Characteristic of shale reservoir is important to the occurrences of shale gas,gas content and the exploitation(Chalmers and Bustin,2008;Gasparik et al.,2013).The lacustrine shale at oil window stage is quite different from marine shale.This study use quantities of testing data from cores and outcrops from the basin edge to analyze the reservoir characteristics in Lacustrine Shale of Middle Characteristic of the shale reservoir is important to the occurrences of shale gas, gas content and the exploitation (Chalmers and Bustin, 2008; Gasparik et al., 2013).
