 非常规天然气作为一种潜力巨大的替代能源，开发应用前景十分广阔。致密砂岩气作为非常规天然气的重要组成部分，越来越受到广大石油地质工作者的关注，而正确地认识致密砂岩气是有效开发利用它的前提条件。文章从致密砂岩气藏的概念、储层的分类方案、储层特性及其与常规储层异同点、气藏成藏过程和分布规律等方面出发，详细阐述了致密砂岩气藏的研究现状，讨论了致密砂岩气藏在国内的分布情况和开发潜力,旨在对国内致密砂岩气藏的前期勘探工作起到一定的指导作用，并为后期开发方案的制订提供合理的参考意见。

Unconventional natural gas has a great development and application prospect as a potential alternative energy source. As an important component of unconventional natural gas, tight sandstone gas gets more and more attention from the oil geologists. The right way to recognize this gas pool is the precondition of gas exploring and utilizing. This paper elaborates the current research situation of tight sandstone gas pool from the concept, classification and features, the similarities and differences compared with the conventional reservoir, accumulation process and distribution rule of gas pool. Meanwhile, it expects to play a certain instruction role in the early exploration of the tight sandstone gas and discusses the distribution situation and exploitative potentiality of gas pool at home in order to provide a reasonable reference for the formulation of later development program.
