进口潜油电泵-进口深井泵-德国KAYSEN泵业

GERMANY KAYSEN PUMP CO .,LTD

德国凯森潜油电泵机组是一种机械采油设备。潜油泵是一种多级离心泵,每一级由一个旋转的叶轮和一个固定的导轮组成,叶轮分浮动和压紧两种,叶轮的结构决定泵的排量,叶轮的级数决定泵的扬程,在油井中潜油电机将机械能传递给潜油泵,潜油泵内的叶轮高速旋转,将原油从井中抽送到地面集油系统。潜油电泵原以美国三大公司引进,经改造开发了各种系列,并获得了较高的泵效、扬程及流量。


主要特点:
 大排量采液是这种采油方法的主要优点。但是,目前潜油电泵也经常应用于产液量比较低的油井。
 这种泵能够把油井中位于上部水层的水转注到下部的注水层中。
 操作简单,管理方便,在市区应用有得于美化环境、减少噪音。
 能够较好地运用于斜井、水平井以及海上采油。
 容易处理腐蚀和结蜡。
 容易安装井下压力及温度等测试装置,并通过电缆将测试信号传递到地面,进行测量读数。
 为适应油井产量递减或发生变化,可采用变频装置调节电源频率来实现,但投入费用较高。
 免修期较长,油井生产时效相对比较高。

 

主要应用:
广泛应用于水、温泉、油田、炼油、石油化工等介质。

使用条件:
环境介质温度:≤150℃;油井温度:50~180℃。温度小于90℃,O型密封圈一般采用*橡胶,叶轮上的止推垫片,一般采用酚醛层压玻璃布板,高于90℃的油井,O型密封圈一般采用氟橡胶(170℃),叶轮上的止推垫片一般选用F4聚苯(150℃)。

含气量:潜油泵在油井工作时是完全浸在井液中的。油井中往往含有不同种类的游离气体,游离气体对潜油泵的工作特性会产生严重影响,当达到一定量时则发生气锁,气体干扰严重影响潜油电泵的正常工作,使电机负载急剧变化或卸载,可在潜油泵的下面安装油气分离器。

井液含砂量:≤0.05%,含砂量:潜油泵在油井中抽汲井液时,要求井液中含砂不超过0.05%。

适用介质:油水或油气水三相混合物,在吸入口压力条件下,气体量占三相总体积流量的0~30%;

井液粘度:≤7mm2/s;

潜油电泵现场管理和故障处理:
       1.1 设备检查部位
  (1)控制柜的检查:运行中接触器是否吸合稳定、振动噪音是否正常;电流记录仪是否准确,卡片上电流数与仪表量程是否一致;
  (2)变压器的检查:声音、油位油色是否属正常现象;高压开关接触良好与否,刀片吃入深度要大于80%;
  (3)井口检查:井口放气阀,油表等是否齐全;闸门开关有无锈蚀,是否灵活等。
  1.2 电泵井投产后的管理要求
  (1)电泵井正常操作由值班采油工操作,发生故障时必须由持有电泵操作证书的专业人员处理;
  (2)机组投入正常运行后,注意更换电流卡片,为确保记录的准确性,在投产前或各种原因停机时应进行电流记录仪零位校正;
  (3)做好各项信息的更新的工作。
  1.3 电泵井清蜡
  在电泵井投产后一周内应进行一次清蜡通井,并根据具体情况制定合理的清蜡周期。清蜡操作要保质保量,应做到起下顺利、不带硬蜡、不顶钻、不堵井筒等事项,在清蜡结束后要建立相关的工作台账。
  2 潜油泵电流卡片分析及故障处理
  潜油泵井电流卡片是反映潜油泵运行过程中时间与潜油电机的电流变化关系曲线,它是潜油泵井日常生产管理的主要依据。正常的电流卡片中,电流曲线应为一条平滑的曲线。
  2.1 泵在受气干扰中运行的电流卡片
  原油脱气,大量气体进泵引起电流波动,导致产量下降。防止方法为:在泵吸入口加气锚或旋转式油气分离器;合理控制套管气;保证机组合理的沉淀度;井液中加入一定量的破乳剂。
  2.2 过载停机的电流卡片
  机组启动后,电流逐渐上升到额定电流值正常运行;随后逐渐上升,*达到过载电流整定值,过载停机。预防及处理方法:正常过载停机应进行洗井;下泵前冲砂,出砂井上提机组;定时清蜡和热洗地面管线;处理缺相,或更换机组。
  2.3 电压波动
  当供电电压波动时,为了满足泵的功率需求,马达电流也会随之波动。原因为供电线路上大功率柱塞泵突然启动引发电压瞬时下降、附近抽油机井多口同时启动,或是有雷击现象。防止办法:在大面积断电后,等其他设备启动后再启泵,并装上避雷设备。
  2.4 供液不足
  由于地层供液不足,泵抽空最终过载关停,系统会自动重启。当电流降低,产液量和泵效就会降低,直至无液进泵,导致欠载停机。原因是在电泵井投产初期,选泵不当,或在生产一段时间后,油井供液。处理办法:缩小油嘴;加深泵挂;更换小排量的机组。
  3 潜油电泵的其它故障的判断与处理[2]
  3.1 管柱漏失判断与处理
  当发生管柱漏失时会出现油压、产量相对下降。带有泄油阀管柱的井,多数是由泄油销被砸断或冲蚀引起,须检泵作业才能恢复生产;管柱腐蚀漏失的井,可通过管柱憋压的验证方法来判断。
  3.2 停机后再启动电流加大
  稠油电泵井停机后重启电流会加大,致使机组被烧毁,此现象在冬季会更加明显。油井在停产后温度降低,油变稠、流动性变差,泵提速变慢,电泵长时间处在高转速下运行,电流很高,导致寿命变短。可采用变频集中切换技术,用一台变频机对多井口进行控制,使每口井实现软启动。投资不大可减少启泵烧机,原油温度的逐渐升高也可减轻原油粘度对泵的影响。3.3 电缆故障诊断与处理
  电缆发生故障表现为地面控制柜过载停机,有时配电盘跳闸电流卡片上的电流曲线突然上升,与电机电气损坏相似,在进行检测时,三相对地绝缘电阻为0,电阻平衡。电缆损坏有两种情况:一是在井口或油管挂处损坏,直阻不超过1Ω;二是远离井口,直阻为2-3Ω,具体损坏处可根据每米电缆的阻值进行测算得出。对于在井口损坏情况,可重新接缆;如果在采油树帽下到几根油管处,可上提油管重新接缆;若损坏很严重,必须检泵作业。
  3.4 井液引起的故障与处理
  这种情况可能发生在井液含砂泥等机械杂质井、电泵试油勘探井、防砂完井生产的新井中。表现是运行电流高、有波动,当超过过载设定值时过载停机,也有可能堵塞油嘴。对于防砂完井生产的新井,原因是完井作业后填砂未冲洗干净,可采取以下办法解决:上调过载设定值;调大油嘴;停机进行反冲洗。
  3.5 套管气引起的故障诊断与排除
  当油井供液不足时,引起油井液面很低接近泵吸入口,套管环空内的气体进入电泵内导致欠载停泵。处理这种情况有以下几种办法:
  (1)控制套压、调低欠载设定值;
  (2)间歇生产,采取人工或控制柜自动启泵方式;
  (3)若泵挂较浅,可加深泵挂深度;
  (4)调低欠载设定值、缩小油嘴;
  (5)对油层进行酸化、压裂等增产措施;
  (6)打开未开采层位生产,补充液源;
  (7)更换与油井相配的电泵泵。
  3.6 机组匹配不合理引起的故障判断与处理
  若电泵机组匹配不合理,也可能引起故障。一是出现“大马拉小车”现象,一般不会引起事故,但当电机余量大时会发生欠载;二是出现“小马拉大车”现象,运行电流会高于额定电流,严重时会出现启动困难和机组烧毁现象。当出现这些情况时,只能待检泵作业时更换合适的电泵机组。



Germany Kaysen submersible pump unit is a mechanical oil production equipment. The submersible pump is a multi-stage centrifugal pump. Each stage consists of a rotating impeller and a fixed guide wheel. The impeller is divided into two types: the impeller is divided into two types. The structure of the impeller determines the displacement of the pump. The number of stages of the impeller determines the pump. The lift of the submersible motor in the oil well transfers the mechanical energy to the submersible pump, and the impeller in the submersible pump rotates at a high speed to pump the crude oil from the well to the ground oil collection system. The submersible electric pump was originally introduced by the three major US companies. It has been developed and developed in various series, and has achieved high pump efficiency, lift and flow.



main feature:

● Large displacement liquid extraction is the main advantage of this oil recovery method. However, current submersible electric pumps are also frequently used in oil wells with relatively low liquid production.

? This pump is capable of transferring water from the upper water layer in the well to the lower water injection layer.

● It is easy to operate and easy to manage. It can be used in urban areas to beautify the environment and reduce noise.

● It can be used in inclined wells, horizontal wells and offshore oil production.

● Easy to handle corrosion and waxing.

● It is easy to install test equipment such as downhole pressure and temperature, and pass the test signal to the ground through the cable to make measurement readings.

● In order to adapt to the diminishing or change of oil well production, the frequency conversion device can be used to adjust the power frequency to achieve, but the input cost is high.

● The maintenance period is longer and the production time of oil wells is relatively high.


 


main application:

Widely used in water, hot springs, oil fields, oil refining, petrochemical and other media.


Conditions of Use:

● Ambient medium temperature: ≤150 °C; oil well temperature: 50~180 °C. The temperature is less than 90 °C, the O-ring is generally made of nitrile rubber, the thrust pad on the impeller, the phenolic laminated glass cloth board is generally used, the oil well is higher than 90 °C, the O-ring is generally made of fluorine rubber (170 °C) ), the thrust washer on the impeller is generally F4 polystyrene (150 ° C).


● Air content: The submersible pump is completely immersed in the well fluid when it is working in the oil well. Oil wells often contain different kinds of free gases. Free gas will have a serious impact on the working characteristics of submersible pumps. When a certain amount is reached, air locks will occur. Gas interference seriously affects the normal operation of submersible electric pumps, causing the motor load to change drastically. Or unloading, the oil separator can be installed under the submersible pump.


● Sand content of well fluid: ≤0.05%, sand content: When the submersible pump draws well fluid in the oil well, it is required that the sand in the well fluid does not exceed 0.05%.


●Applicable medium: oil-water or three-phase mixture of oil and gas, under the pressure of the suction port, the gas volume accounts for 0~30% of the total volume flow of the three phases;


● Well fluid viscosity: ≤ 7mm2 / s;


Submersible electric pump site management and fault handling:

       1.1 Equipment inspection site

(1) Checking of the control cabinet: Whether the contactor is stable during operation, whether the vibration noise is normal, whether the current recorder is accurate, and whether the current on the card is consistent with the meter range;

(2) Inspection of transformer: Whether the sound and oil level are normal; if the high-voltage switch is in good contact, the depth of the blade should be greater than 80%;

(3) Wellhead inspection: Whether the wellhead venting valve, oil meter, etc. are complete; whether the gate switch is rusted, flexible or not.

1.2 Management requirements after the electric pump well is put into operation

(1) The normal operation of the electric pump well is operated by the duty oil producer. When the fault occurs, it must be handled by the professional who holds the electric pump operation certificate;

(2) After the unit is put into normal operation, pay attention to the replacement of the current card. In order to ensure the accuracy of the recording, the current recorder zero calibration should be performed before the production is put into operation or when the various reasons are stopped.

(3) Do a good job of updating all kinds of information.

1.3 Electric pump well waxing

A wax cleaning well should be carried out within one week after the electric pump well is put into production, and a reasonable wax removal cycle should be established according to the specific conditions. The wax cleaning operation should be quality and quantity, and should be carried out smoothly, without hard wax, no drilling, no plugging, etc., and the relevant work ledger should be established after the wax is finished.

2 Submersible pump current card analysis and troubleshooting

The submersible pump well current card is a curve that reflects the relationship between the time of the submersible pump and the current of the submersible motor. It is the main basis for the daily production management of the submersible pump well. In a normal current card, the current curve should be a smooth curve.

2.1 Current card for pump running in gas interference

Degassing of crude oil, a large amount of gas entering the pump causes current fluctuations, resulting in a decrease in production. The prevention method is: adding a gas anchor or a rotary oil separator in the pump suction port; reasonably controlling the casing gas; ensuring a reasonable sedimentation degree of the unit; adding a certain amount of demulsifier to the well liquid.

2.2 Current card for overload shutdown

After the unit is started, the current gradually rises to the rated current value for normal operation; then it gradually rises, and finally reaches the overload current setting value, and the overload stops. Prevention and treatment methods: normal overload shutdown should be carried out for washing; sand pumping before the pump, lifting the sand pumping unit; regular wax cleaning and hot washing of the ground pipeline; processing phase loss, or replacing the unit.

2.3 Voltage fluctuations

When the supply voltage fluctuates, the motor current fluctuates in order to meet the pump's power requirements. The reason is that the sudden start of the high-power plunger pump on the power supply line causes the voltage to drop instantaneously, and multiple ports of the nearby pumping unit are started at the same time, or there is a lightning strike. Prevention: After a large area power failure, wait for other equipment to start and then start the pump and install lightning protection equipment.

2.4 Insufficient liquid supply

Due to insufficient liquid supply in the formation, the pump will eventually shut down and the system will automatically restart. When the current is reduced, the liquid production and pump efficiency will be reduced until there is no liquid to enter the pump, resulting in underload shutdown. The reason is that in the initial stage of commissioning of the electric pump well, the pump is improperly selected, or the oil well is supplied after a period of production. Treatment: reduce the nozzle; deepen the pump; replace the small displacement unit.

3 Judgment and treatment of other faults of submersible electric pump [2]

3.1 Pipe column missing judgment and treatment

When a column leak occurs, oil pressure and relative yield decrease. Most wells with drain valve string are caused by the dumping pin being smashed or eroded. It is necessary to check the pump operation to resume production; the well leaked by the pipe string can be judged by the verification method of pipe string rolling. .

3.2 Increase the current after the shutdown

After the shutdown of the heavy oil electric pump well, the restart current will increase, causing the unit to be burned. This phenomenon will be more obvious in winter. After the oil well is stopped, the temperature is lowered, the oil becomes thicker, the fluidity becomes worse, the pump speed is slower, the electric pump runs at a high speed for a long time, and the current is high, resulting in a shorter life. The variable frequency centralized switching technology can be used to control multiple wellheads with one frequency converter, so that each well can achieve soft start. The investment is not large enough to reduce the pumping, and the gradual increase of the crude oil temperature can also reduce the impact of the viscosity of the crude oil on the pump. 3.3 Cable Fault Diagnosis and Processing

The cable failure occurs as an overload stop of the ground control cabinet. Sometimes the current curve on the switchboard current card suddenly rises, similar to the electrical damage of the motor. When detecting, the relative insulation resistance of the three is 0, and the resistance is balanced. There are two kinds of cable damage: one is damage at the wellhead or tubing, the direct resistance is less than 1Ω; the second is far away from the wellhead, the direct resistance is 2-3Ω, and the specific damage can be calculated according to the resistance of each meter of cable. . For the damage at the wellhead, the cable can be reconnected; if there are several oil pipes under the tree cap, the oil pipe can be reconnected; if the damage is serious, the pump must be checked.

3.4 Faults and treatment caused by well fluid

This situation may occur in wells with mechanical impurities such as sand and mud, electric pump test oil exploration wells, and sand control completion. The performance is high running current, fluctuating, overload stop when the overload setting value is exceeded, and it is also possible to block the nozzle. For the new wells produced by sand control completion, the reason is that the sand filling after the completion operation is not washed out, the following solutions can be taken: increase the overload setting value; adjust the large nozzle; stop the backwashing.

3.5 Fault diagnosis and elimination caused by casing gas

When the oil supply of the oil well is insufficient, the oil well level is very low and close to the pump suction port, and the gas in the casing annulus enters the electric pump, causing the underload to stop the pump. There are several ways to handle this situation:

(1) Control the sleeve pressure and lower the underload setting value;

(2) Intermittent production, adopt manual or control cabinet to automatically start pumping mode;

(3) If the pump is shallow, the pumping depth can be deepened;

(4) Lower the underload set value and reduce the nozzle;

(5) Measures to increase the production of oil layers by acidification and fracturing;

(6) Open the unmined horizon production and replenish the liquid source;

(7) Replace the electric pump that matches the well.

3.6 Fault diagnosis and treatment caused by unreasonable unit matching

If the electric pump unit is not properly matched, it may cause a malfunction. First, the phenomenon of “large horse-drawn car” appears, which generally does not cause an accident. However, when the motor has a large margin, underload occurs. Second, the phenomenon of “small horse-drawn carriage” appears, and the running current will be higher than the rated current. Difficulties in starting up and burning of the unit can occur. When these conditions occur, only replace the appropriate pump unit when the pump is in operation.
