本文叙述了我作业区所管辖八区下乌尔组油藏,油水井在修井过程中造成费用发生的原因。由于作业区的油水井井深、井况复杂,管杆偏磨严重。油田进入了中高含水开采阶段,作业难度非常大。这些复杂井况抽油井在生产过程中,油管、抽油杆腐蚀结垢严重。井下抽油泵、工作降低泵效,缩短井下工具寿命,严重造成泵卡等一系列生产问题,大量的油管、抽杆报废,造成极大浪费,抽油井时率降低,检泵周期短。针对问题的结症,采取针对性的解决手段,尽可能减少材料的消耗。 This article describes the reasons for costs incurred in the workover process of the Lower Wuer Formation oil-water wells in the eight districts under my jurisdiction. Due to the well depth and the complicated well conditions of the oil and gas wells in the operation area, the pipe eccentric wear seriously. Oilfield has entered a high water cut stage, operation is very difficult. These complex well conditions pumping wells in the production process, tubing, sucker rod corrosion scale serious. Downhole pump, work to reduce pump efficiency, shorten the life of underground tools, pump cards and a series of serious production problems caused by a large number of tubing, pumping rod scrapped, resulting in tremendous waste, pumping wells when the rate is reduced, the pump cycle is short. For the problem of knot disease, take targeted solutions to minimize the consumption of materials.
