以美国典型页岩气盆地的页岩气成藏条件为基础,结合国内学者讨论,归纳出页岩气成藏条件包括:生烃条件(沉积环境、有机质类型、丰度、成熟度、单层厚度)、储集条件(孔隙度、渗透率、裂缝发育程度、矿物成分)、盖层及保存条件(构造运动强度、地层水条件)以及地层压力和埋深等,有利的页岩气成藏指标的下限为:w(TOC)≥2.0%,Ro≥1.1%,单层厚度≥9m,脆性矿物含量≥40%。 Based on the shale gas accumulation conditions in typical shale gas basins in the United States and the discussion by domestic scholars, the conditions of shale gas accumulation are summarized as follows: hydrocarbon generation conditions (sedimentary environment, organic matter type, abundance, maturity, Thickness), favorable reservoir conditions for shale gas accumulation (porosity, permeability, degree of fracture development, mineral composition), caprock and preservation conditions (tectonic motion intensity and formation water conditions), formation pressure and burial depth The lower limit of the indicator is: w (TOC) ≥2.0%, Ro≥1.1%, monolayer thickness≥9m, and brittle mineral content≥40%.
