Analysis of Shale Reservoir Forming Condition of Longmaxi Formation of Weixin Sag
摘要
Abstract
Silurian Longmaxi Formation of Weixin Sag in the Dianqianbei Depression is one of the two principle exploration targets in Weixin Sag.This paper studies Longmaxi Formation through the experiment data of porosity,permeability,X-ray diffraction etc.The result shows that,compared with shale gas of North America and Jiaoshiba in Shichuan Province,this shale reservoir has richer organic content and higher organic maturity with good gas generation potential.This shale reservoir has good adsorption capacity,low porosity and permeability,and so has good storage capacity and poor physical properties.This reservoir has moderate brittle mineral content,moderate Young's modulus,and low Poisson's ratio.While the lower part of Longmaxi Formation has greater organic content,better porosity and permeability,and higher brittle mineral content,and so has greater exploration capacity.关键词
