在小修作业中,为了保证油井的正常生产要对油水井进行必要的维护作业:检泵。抽油泵在日常生产过程中,受到机械磨损及地层砂、蜡、气、水等不同腐蚀侵害,使抽油泵各部件受到不同程度损害,甚至漏失或蜡卡、泵杆断脱等使油井减产、停产等。因此,及时检泵、换泵井下作业施工,是维护油井正常生产的必要程序。油井检泵按照检泵原因和目的分为计划检泵和躺井检泵。其中,计划检泵,是按预定周期或生产到一定限度进行周期检泵或加深泵挂、换泵、泵升级等;躺井检泵,是指在油井正常生产过程中或还没到计划检泵周期,由于抽油泵的各部件突发故障或油井由于其他原因的突然变化造成产量大幅下降,甚至停产,而进行的检泵施工。随着修井技术的不断发展和提高,一些新工艺、新技术也不断的应用于检泵工艺。
In minor repairs, in order to ensure the normal production of oil and gas wells to carry out the necessary maintenance operations: pump. Pumps in the daily production process, by mechanical wear and sand, wax, gas, water and other corrosion damage, so that various parts of the pump suffered damage or even missing or wax card, pump rod off the oil well to cut production, Stop production and so on. Therefore, the timely detection pump, pump downhole construction work, is to maintain the normal production of oil wells necessary procedures. Oil well inspection pump in accordance with the reasons and objectives of the inspection pump is divided into plans to check the pump and lying well pump. Among them, the plan to check the pump, is scheduled to cycle or production to a certain limit cycle pump or deepen the pump hanging, changing the pump, pump upgrades, etc .; lying well pump, refers to the well in the normal production process or not yet planned inspection Pump cycle, due to pumping parts sudden failure or oil wells due to sudden changes in other causes a substantial decline in production, or even stop production, while the pump construction. With the continuous development and improvement of workover technology, some new processes and new technologies are also continuously applied to the process of pump inspection.
