抽油机是油田生产的三大机采举升方式之一,在油田的高产稳产中发挥着重要作用,抽油泵作为抽油机井的重要组成部分也要根据油田的发展做进一步的改进和完善。目前应用的普通抽油泵阀芯均为球形结构,启动压力大,开启时间长,冲程损失较大,而且为单一流道,过流面积较小,导致下冲程阻力大,杆柱弯曲,而发生偏磨。针对这一问题,试验应用了多通道高效抽油泵,本文通过对该泵结构和原理的研究以及对该泵试验效果的分析确定其对聚合物区块和水驱区块的适应性。 Pumping unit is one of the three major methods of machine-building and lifting in oilfield production. It plays an important role in the high and stable output of oilfield. As an important part of pumping well, pumping unit should be further improved and perfected according to the development of oilfield . At present, the common pumping valve spools are all spherical in shape. The starting pressure is large, the opening time is long, the stroke loss is large, and the single flow passage has a small flow area, resulting in a large resistance in the lower stroke and bending of the column. Partial wear occurs. In response to this problem, the test applied a multi-channel high-efficiency pump, this paper through the pump structure and principle of the pump test results and analysis of its determination of the polymer block and water-block adaptation.
