文明寨油田部分生产油井存在结蜡、油稠、井温低的现象,在保持正常生产时不可避免的要采取洗井等措施,当洗井液与地层流体、岩石不配伍时,会对油气层造成损害或堵塞,严重时会造成水锁损害,短期或长期影响油井产量。文章究污染油层的机理出发,结合单井生产实际,采用高效活性解堵工艺,成功解除洗井替油过程中造成的油层污染问题。

Part of the producing well exists paraffinning,viscous crude oil production,low well temperature,pHenomenon in Wenmingzhai Oilfield,production inevitable to take measures such as washing,when washing fluid is not compatible with formation fluid or litho,it will be damage or blind hydrocarbon reservoir,even cause serious damage to the water lock,short-term or long-term effect on oil production.The paper studies on the mechanism of oil pollution,combined with the practice oil production,high performance active plugging relief technology,successfully relieved for washing oil wells process caused by pollution.
