摘要: 煤储层渗透性是制约煤层气勘探选区的重要参数,影响渗透率差异分布的因素有很多,从裂隙系统的发育、煤储层有效应力、煤层构造演化、煤岩变质程度几个方面阐述了它们与高渗区空间分布的关系及其研究进展。对其研究技术、手段、主要认识及存在的问题等进行了系统的总结。对有效预测煤储层渗透性、发展渗透性描述理论、寻找有利勘探区带具有重要意义。

Abstract:

The coalbed gas reservoirs permeability is an important factor controlling the selection of exploration targets of coalbed gas.There exist lots of factors

influencing the differencial distribution of permeability,from such aspects as the development of fracture system,the effective stress of coalbed reservoirs,coal

bed tectonic evolution and coalbearing rock metamorphic degree,the relationship among them and spacial distribution of highly permeable areas and the research progress

are illustrated.Syetemalic sumary is carried out to the research technology,methoclology,recognition and existing problems,which is meaningful to effectively pridecting

coalbed permeability,developing permeability description theory and searching for favarable explorative areas.

Key words: coalbed gas, permeability, fracture system, effective stress, tectonic evolution, metamorphic degree
