摘要
CS油田南断块油井结蜡严重,常规清防蜡技术效果不佳,油井频繁遇阻、停抽,降低生产时率,影响油井产量。为解决油井结蜡遇阻、延长油井检泵周期,应用轻便型油井自洗装置和空心杆油管内热洗工艺,经现场跟踪验证:清蜡效率高、成本低。
Wax deposition is serious in South Fault Block of CS Oilfield,and the effect of conventional wax removal and control technology is not good.Oil wells are frequently blocked and shut down,which reduces the productivity and affects the production of oil wells.In order to solve the problem of wax deposition in oil wells and prolong the period of pump inspection in oil wells,The application of portable oil well self-washing device and hot washing process in hollow rod tubing shows that the wax removal efficiency is high and the cost is low.
