摘要： 通过分析侧流式深抽泵的工作原理以及受力状况，建立了侧流式深抽泵在油井深抽条件下的悬点载荷计算模型，经过分析论证得出，与普通管式泵相比侧流式深抽泵在上下冲程中均能起到减载的作用，适合油井的深抽。通过对一口深抽井的实例计算，发现侧流式深抽泵深抽井均比普通管式泵的最大、最小载荷减小7%左右，该结果说明侧流式深抽泵在油井深抽设计中具有一定的优势，可为侧流式深抽泵在油田深抽井的推广应用提供技术参考。

Abstract： Based on the mechanism and force analysis for the side-stream deep pump, a mathematical model is established to calculate the polished rod load for deep well adopting the side-stream deep pump. Through theoretical analysis, we can see that the side-stream deep pump can reduce the maximum and minimum load contrasted with the tube pump, and it qualified in deep well. By calculating a deep well example, it’s been found the side-stream deep pump decreases maximum and minimum load around 7%, and it is suitable to the deep well. The results also indicate that the side-stream deep pump has definite advantages in the design of deep drawing, and it provided technical references for the further application of the side-stream deep pump in the oil field’s deep wells.
