摘要
在研究体积法计算煤层气储量以及煤层气含量的测定方法时,发现现行的《煤层气资源/储量规范》存在一些问题,如规范性引用文件已经滞后,体积法公式基准选取欠妥,原煤基、空气干燥基和干燥无灰基三种基准的含气量换算公式不当,原煤基含气量的测定方法操作性不强等。对这些问题的原因及其造成的影响做了详细的阐述,并提出了相应的修改建议。
Some problems that exist in operating CBM resources/reserves standards are found when studying the content determination method of CBM and its reserves calculation by volumetric method.The problems are as follows: the standard reference file has lagged behind;the basis of volumetric method equation is not properly selected;the gas content conversion equations of in-situ basis,dry ash-free basis and air-dry basis are improper;the method which is used to determine the gas content of in-situ basis is not operated very well.In this paper,the cause of these problems and their influences are described in detail and the corresponding revised suggestions are also proposed.
