随着我国的改革开放,油田的生产在进几十年得到了飞速发展,但也有许多的油田油井在向老龄井过渡。并伴随着许多新的问题在油田采油工程中出现,其中最为严重的就是油管与抽油杆等机械的磨损。它们的出现严重的影响了油田向高效率、低耗能的生产方向发展。 With the reform and opening up of our country, the production of oilfields has progressed rapidly in recent decades. However, there are also many oilfields in transition to aging wells. And along with many new problems in the oil recovery project, the most serious of which is the tubing and sucker rod and other mechanical wear and tear. Their appearance has seriously affected the development of oilfields towards high efficiency and low energy consumption.
