查询词典 pumping

Studied pumping well system in this article, the intermediate power transmission parts uesed flexible rod, the downhole assembled rod pump, the ground driving device would transform up and down reciprocating motion into rotating motion. With own mechanism rounded trip for the downhole flexible rod and pump. Wellhead polished rod changed common stell for flexible polished rod. It was a innovation in theory study and craftwork method. It was a remarkable feature in this article, because these innovations were not studied and attempted for prehuman.

本文所研究的抽油系统，中间动力传动部件采用柔性抽油杆，井下配套杆式抽油泵，其地面驱动装置将传统抽油机驴头的上下往复运动变为旋转运动，并且能够利用自身结构对井下柔性抽油杆及泵体实现起下作业，井口光杆也由普通钢质光杆变为柔性光杆，这是理论研究和工艺方法的创新，这些创新都是前人所没有研究和尝试的，是本文的一大显著特点。
