在结蜡油井中,普遍采用从油套管环形空间加入药液,而达到油管清防蜡的目的。但同一种药剂,对不同类型的井,采用不同的加药方法,其试验效果不一样。我们在几年的油井加药试验中,根据油井的不同情况,采用了不同的加药方法及合理的工作制度,已取得较好效果。基本上解决了蜡卡、蜡堵及回压升高等问题,摸索到了一些加药规律。下面对一些不同类型井的加药办法作一简介。 Waxing oil wells, the universal use of casing from the oil ring to join the liquid chemical, and to achieve the purpose of anti-wax tubing. However, the same agent, different types of wells, using different dosing methods, the test results are not the same. In a few years of well dosing experiments, we have adopted different dosing methods and reasonable working systems according to the different situations of oil wells and have achieved good results. Basically solved the wax card, wax blocking and back pressure and other issues, found some dosing rules. Here are some different types of wells dosing approach for a brief introduction.
