在油田开发过程中,应用机采系统采油存在着管杆偏磨问题。管杆偏磨是指抽油杆接箍及其本体与油管内壁产生摩擦,而引起抽油杆、管磨损导致损坏的现象,它是油井频繁作业、缩短检泵周期的主要原因。通过对梁西管理区三年来维护作业井作业原因的深入调查分析,针对油田开发中后期的特点,提出并应用了减少管杆偏磨的系列配套措施,提高了检泵周期和油井管理水平。
In the process of oilfield development, there is a problem of partial eccentricity of pipe rod in the production of oil by mechanical mining system. Pipe rod wear refers to the sucker rod coupling and its body with the tubing wall friction, resulting in sucker rod, tube wear damage caused by the phenomenon, it is the oil wells frequent operations, shorten the main reason pump cycle. Through in-depth investigation and analysis of the reasons for maintenance of operation wells in Liangxi Management Area in the past three years, a series of supporting measures to reduce partial wear of the pipe rods are proposed and applied in accordance with the characteristics of mid-late development of oilfields, and the inspection pump cycle and well management level are improved.
