摘　　要：经对吐哈油田 85口井测试资料的统计分析 ,指出仅凭主观经验确定的开关井工作制度对中、高渗透层和低渗透层存在严重的不合理性。本文从孔隙度与开关井时间存在相互制约关系入手 ,统计分析了各区块井层的测试资料 ,并通过作图 ,对不同储集层分别进行研究 ,找出了开关井次数与开关井时间的分布规律 ,提出了一套可行的地层测试工作制度确定方法。Through statistical analysis to DST data of 85 wells in Tuha Oilfield,it indicates that fixing opening and shut-in regime by subjective experience has its serious irrationality to medium,high and low permeable formations.This paper,starting with the relationship of conditioning each other between porosity and opening,shut-in time,statistically analyzes test data from wells of differents blocks,and through plotting ,studies different reservoris respectively,finds out the analysis regularity between number of opening and shut-in and time of opening and shut-in ,and puts forward a set of applicable methods to fix DST opening and shut-in regime
