针对目前螺杆泵井生产过程中存在的卡泵问题,油田常以常规热洗、或者吊车上提光杆热洗的方面进行处理,然而对于“深液面、低沉没度”供液能力不足的井,这两种办法常常都无济于事,会导致油井检泵频繁,大大影响了油井的时率、利用率。油田通过反复实践找到了以改生产流程,“上提光杆正注洗井”为主的解除卡泵的新方法,实现了不检泵、不修井,直接解除卡泵故障,减少了躺井,提高了油井开井率和生产时率,甚至解决了以往依靠检泵以至修井也无法解决的疑难问题。经现场应用和效果评价,具有一定的可操作性和实用性,取得了较好的经济效益。 In view of the card pump problem existing in the production process of the screw pump well at present, the oil field is often treated by the conventional heat-washing or the hot-rod cleaning of the light-emitting rod on the crane. However, for the “deep liquid level, Of the wells, these two methods are often useless, will lead to frequent inspection of oil wells, greatly affected the rate of oil wells, utilization. Through repeated practice, the oilfield discovered a new method of releasing the card pump that mainly relies on the production flow modification and the ”light-up lever is injecting and washing the well", and realized no pump failure and no well-servicing, and directly eliminated the card pump failure and reduced Laying wells, raising the well open rate and production rate, and even solved the past rely on the pump and even workover can not solve the difficult problems. The field application and effect evaluation, has a certain degree of maneuverability and practicality, and achieved good economic returns.
