化学堵水剂在油田生产中的应用

针对油气井见水早造成注水井波及系数降低及投资费用增加等方面的危害,分析了选择性堵水调剖剂和非选择性堵水调剖剂的特点及其在油田实际生产过程中应用情况,选择性堵水剂是利用油和水、出油层和出水层之间的性质差异来实现选择性堵水的;非选择性堵水技术则主要用于封堵单一水层或高含水层。文章还总结了化学堵水调剖的应用效果,展望了堵水调剖的发展前景。

The summary of chemical blocking agents application in oilfield production

In terms of early water breakthrough of oil and gas wells that result in sweep reducing and costs increasing,this paper analyzes the characteristics of selectivity of water plugging agent,including water-based blocking agent,oil-based blocking agent and alcohol-based blocking agent.And it also analyzes the characteristics of non-selective of water plugging agent including cement blocking agent,precipitated blocking agent,resinbased blocking agent,gel-type water blocking agent and gel blocking agent.It points out the actual production process in oil field applications.Summarize the application of the chemical effects of water plugging and look forward to the future development of water control.
