摘　　要：中途测试资料可作为优选压裂层的直接依据。联系鄂北气田杭锦旗含水气藏、大牛地老区压裂改造的实际效果,分析中途测试资料在压裂选层中的应用情况。测试资料显示污染严重的井,适合进行小规模解堵压裂;测试期间产水量较大的井、下部储层含水而无法有效控水的井、压力亏空较大的井,不适合进行压裂改造。Drill-stem testing data can be used as a direct basis for the preferred fracturing layer.Based on the actual effect of fracturing in the water-bearing gas reservoir of Hangjinqi and the old area of Daniudi in Ebei gas field,the application of the drill-stem testing data in the fracturing layer is analyzed.The test data shows that the seriously polluted well is suitable for small-scale plug removal fracturing.Wells with large water production during the test,wells with water in the lower reservoir and unable to effectively control water,and wells with large pressure deficits are not suitable for fracturing.
