塔架式抽油机在冀东油田的应用

Application of tower oil pumping unit in Jidong oilfield

近年来,由于冀东油田油井井深增加、开采条件变差、土地资源的制约等原因,使游梁式抽油机在适应性方面出现一些问题,主要表现为能耗高、质量大,占地面积大,不能满足大悬点负荷、长冲程、低冲速的工况要求等。为解决上述问题,自2010年以后开始批量使用塔架开关磁阻电动机型无游梁式抽油机(以下简称塔架式抽油机),它占地面积小,适用于井位密集,井场狭小的工况;而其长冲程、低冲速的特点,可减少杆、管偏磨,延长杆、管使用寿命。此抽油机还能够满足高负荷、调参方便、节约电能等要求,具有广阔的应用前景。

In Jidong oilfield, because of the well depth increasing, worse mining conditions, land resource constraints, some problems on the adaptability are exposed in the beam pumping unit, such as higher energy-consumption, bigger weight, larger area and it can not meet the requirements on bigger suspension point load, long stroke, low speed working conditions. In order to solve these problems, the tower oil pumping unit has been batch used since 2010. Because it covers smaller area, the tower oil pumping unit applies to densely wells and narrow site condition; based on long stroke and low speed characteristics, the life of rod and pipe can be prolonged by reducing eccentric wear of rod and tube. Because tower oil pumping unit has higher load, longer stroke, lower speed, parameter easy-adjusting and energy-saving, it has a broad application prospect.
