文中综述了国外利用测井评价煤层气储层特性的现状及实例.成果表明.测井能用于精确确定煤层厚度和煤的工业分析值,对煤层气含量、渗透率的估算已成可能.测井还能用来帮助确定吸附等温线的精度.
In this paper, the status quo and examples of the evaluation of CBM reservoirs using logging in foreign countries are summarized.The results show that logging can be used to accurately determine the thickness of coal seams and industrial analysis of coal, and it is possible to estimate the CBM content and permeability. Well logging can also be used to help determine the accuracy of adsorption isotherms.
