Abstract:

Shale reservoirs are characterized by much influencing factors, complicated relationship between porosity and permeability, as well as strong heterogeneity, so it is difficult to evaluate.  In order to determine the weight of eva?luation parameters for shale gas reservoirs, Longmaxi shale in Nanchuan area of Chongqing was taken as an example, and the gray correlation analysis method and fuzzy comprehensive evaluation method were applied to evaluate the shale reservoir quality. The result shows that the total organic carbon content （TOC）, vitrinite reflectance （Ro）, effective thickness, porosity, brittle mineral content and permeability are the main factors affecting the shale reservoir quality, and the weights are 0.257 9, 0.133 1, 0.119 1, 0.149 6, 0.139 2 and 0.201 1, respectively. The comprehensive evalua?tion factor of shale reservoir is 0.41?0.93 through the fuzzy mathematics calculation of each parameter. On this basis, the distribution of shale gas reservoirs of Longmaxi Formation in Nanchuan area was predicted.
