| 摘 要： | 页岩气因其储量大、分布广、清洁，被认为是替代常规能源的重要能源之一。此类气藏属于特低孔、特低渗且存在吸附解吸等特性的非常规气藏。与常规气藏相比，因其具有特殊的微观储存结构和复杂的渗流机理，导致一般无自然产能或低产。因此能否认清其储渗结构和渗流机理是制约页岩气藏有效开发的瓶颈之一。为此调研了页岩气孔渗特征、评价方法以及多尺度下的渗流产出机理发展现状，为下一步的页岩气藏动态分析，产能预测等研究提供理论支撑。

| Abstract: | Due to large reserves,wide distribution and cleanliness,shale gas is considered as one of the important energy sources alternative to conventional energy.This kind of shale gas reservoir is unconventional gas reservoir with extra-low porosity,ex tra-low permeability and adsorption/desorption characteristics.Compared with the conventional gas reservoir,its special micro stor age structure and complex seepage mechanism lead to no natural productivity or low productivity.Therefore,whether or not to make clear ... |
