随着油田生产的不断发展和油田油井向老龄井过渡,油田采油工程出现了许多新的问题,特别是机械采油过程中出现的油管、抽油杆的机械磨损,严重的影响着油田高效、低耗生产的发展。
With the continuous development of oilfield production and the transition from oilfields to aging wells, many new problems have arisen in oilfield production engineering. Especially, the mechanical wear of tubing and sucker rod in the process of mechanical oil recovery seriously affects the high efficiency and low Consumption of production development.
