| 摘 要： | 针对文留油田自喷转抽井抽油作业过程中敏感性地层易受入井液污染,导致渗透率下降,采收率降低的问题,研制了新型可带压作业抽油泵。该泵主要由泵上接头、泵筒、柱塞总成和防喷装置总成等组成,是在普通泵的基础上增加了带压作业防喷装置,能够较好地防止下泵过程中出现的井喷及溢流。文留油田的现场应用效果表明,该泵施工成功率100%,具备操作简单、施工省时省费用、减少洗井液对油井污染等特点,值得大面积推广应用。 |

| Abstract: | The sensitive formation is easily polluted by well liquid in the oil pumping process in flowing-to-pumping wells in Wenliu Oilfield to cause the decrease of permeability and reduction of recovery rate.Considering the problem,a new type of snubbing subsurface pump was developed.The pump mainly consists of pump sub,pump barrel,plunger assembly and blowout prevention assembly.By adding a snubbing blowout prevention device in the common pump,this pump is capable of effectively preventing the blowout and overflow in the process of pump lowering.The field application in Wenliu Oilfield shows that the operation of the pump reaches a 100% success rate.It is characterized by simple operation,time saving and reduction of oil well pollution caused by flushing fluid.Therefore,it is worth extensive spreading and applying. |
| Keywords: | Wenliu Oilfield snubbing operation subsurface pump overflow blowout prevention device |
