摘要
长庆油田油井埋藏深、单井产量低,为降低作业成本,研制了定筒式顶部固定、机械与皮碗双密封的双卡式杆式泵。现场应用5 000口井,试验结果表明:杆式泵检泵周期约为管式泵的2/3,井下作业总量较管式泵高15%,起油管比例达到70%。杆式泵自身结构是一个重要的影响因素,从杆式泵支撑总成、泵阀结构以及支撑总成与油管配合尺寸3个方面深入剖析了杆式泵产生故障的原因,只有实现了标准化、系列化、通用化,才能真正发挥杆式泵优势。
Oil wells in Changqing oilfield buried deep,low single well production.In order to reduce the cost of operation,a set top drum fixed,mechanical,dual card dual seal cup rod pump were de-veloped,basic structure was composed by oil pump,bearing set and blowout preventer.After field application 5 000 wells,the test results show that,the sucker rod pump inspection period is about tube pump 2/3,downhole operation volume tube pump 15%,an oil pipe ratio cases reached 70%. Rod pump structure itself is an important influencing factor.This paper Article from the rod pump support assembly,valve structure and the support assembly and tubing with the size analy-zes three aspects of the cause of failure rod pump,also pointed out that the promotion of rod pump is a very long way,only to achieve standardization,serialization,universal,can really play a rod pump advantage.
