摘要
大庆油田为确保稳油控水而进行的注水结构调整中使用了多种注水井解堵增注方法。本文介绍了各种方法的概况、特点和适应性,根据全油田1991-1994年统计资料比较了各种方法的技术经济效果,强调了根据井况选用增注方法的重要性。
In this review paper the methods and techniques for removing various precipitations plugged in raservoirs and for enhancing injectivity of water injection wells in Daqing Oil Fields are described briefly for their basic principles, characteristic features and proper uses. Their techno-economical aspects are compered on the basis of statistical data in 1991 - 1994. The suitability of the methods and techniques for different purposes is stressed on. The methods and techniques reviewed are:acidization by common acids and by various retarded acids in different forms; chemical thermogeneration; common and multiple hydrofracturing; repeated perforation by using bullet YD-89; hydraulic and supersonic oscillation; and others.
