在油田生产的过程中,油井结蜡是影响油井生产的一个重要原因。热洗是减少和清除井下管杆泵结蜡,进行油井维护管理的最重要手段,可以改善井筒流动条件,光洁油管内壁。讨论油田洗井方式,阐述热洗机理,并对热洗周期和热洗时间进行试验。通过实践,我们摸索了水驱油井结蜡判断及洗井的一些方法,并在实际生产中进行了推广应用,取得了良好的效果。
Oil well waxing is one of the most important factors affecting oil well production in oilfield production. Hot wash is to reduce and remove downhole pipe pump wax, the most important means of oil well maintenance and management, can improve wellbore flow conditions, clean the inner wall of tubing. Discusses oil well washing patterns, elaborates the hot washing mechanism, and tests the hot wash cycle and hot wash time. Through practice, we have explored some methods of waxing judgment and well washing in waterflooding wells, and have carried out popularization and application in actual production and achieved good results.
