摘　　要：本文通过产能模拟实验验证了致密砂岩气藏有效储层物性下限,并应用压力敏感性试验建立覆压条件下孔渗相关函数,求出苏里格气田东区致密砂岩在地层条件下的有效储层物性下限,指出在地表条件下鄂尔多斯盆地致密砂岩砂岩气藏有效储层孔隙度下限为5%,渗透率下限为0.1×10-3μm2,为目前的致密砂岩气藏开发工艺指明了方向。this paper,relying on the production capacity simulation experiment,proved the petrophysical lower standard study of tight sandstone effective reservoir;at the same time,using the pressure sensitivity experiment to establish fitting equation the between porosity and permeability,the corresponding petrophysical lower standard study of tight sandstone effective reservoir in formation conditions is computed. The research conclusion not only extend the definition of tight sandstone but also direct the production techniques in tight sandstone reservoir.

关 键 词：产能模拟实验 有效储层物性下限
