摘　　要：利用MDT(电缆地层测试仪)测压力剖面点的压力资料,根据压力梯度可分析判断油气水层。但因测试受各种因素的影响而使判断存在不准确性,因而存在对储集层的流体性质作出错误判断的可能性。利用试井分析方法,判定MDT是否测取了真实的地层压力,提供了取舍的方法,经矿场实际应用,取得了较好的效果。With pressure data of the pressure profile acquired with the modular formation dynamics tester tool （MDT）, the oil, gas and water zones/layers can be identified in general. But there exists erroneous adjustment probability of reservoir fluid property, due to various influ- encing factors in the process of well testing. With the method of well test analysis, this paper determines whether the MDT measures the re- al formation pressure or not, and proposes the choice of accepting the data or rejecting them given by MDT. The field application indicates that this method can be used to get good results in field application.
