摘　　要：大牛地上古生界砂岩气藏致密低渗,进行压裂投产必不可少。根据裂缝井试井解释理论,综合运用压前、压后实测试井资料,分析试井曲线形态变异特征及地层参数变化,动态认识地层储渗特征、边界特征、井层污染程度等,深入剖析评价压裂改造增产效果及其原因,结合测试情况分析压裂施工规模对压裂效果的影响。该分析方法对同类型气藏的科学开发具有一定的指导和借鉴意义。Fracturing is a absolutely necessarily method for Daniudi upper Paleozoic sandstone gas reservoir to be put into production because of its compact reservoir. According to well test theory of the fracturing and factual well test data, the paper has dynamically analyzed differentiation of well test curves characteristics and reservoir parameters, characteristics of underground percolation and reservoir boundary, information of formation damage, fracturing effect and its factors, and influence of fracture scale. The analysis method in this paper is correct, its result being reliable, which is of certainly guiding and referable significance for scientifically developing the same gas reservoirs.
