煤层气含量是煤层气勘探过程中必须精确获取的最重要的煤储层参数之一,是决定一个区块的煤层气资源能否进行商业化勘探开发的先决条件。本文介绍了目前中国煤层气含量测试技术、测试设备及国内外研究历程,并结合实际测试经验,提出按照国家标准进行气含量测试时仍会产生较大误差。从观测数据的准确性等方面入手,定性分析了实际测试过程中影响观测质量的因素和误差产生的原因,提出了减少误差、准确获取煤层气含量参数的完善措施,对煤层气含量精确测试提出了新的建议。

Gas content of CBM is one of the most important parameters of coal reservoir, which should be obtained accurately in the CBM prospecting process. It is a prerequisite condition for determining whether the CBM resources in a block can be commercially explored or developed. The paper described the cur rent testing technique and equipment for testing gas content of CBM in China, as well as the progress of research in this field at.home and abroad. Based on practical experiences with testing, the authors con sider that if the gas content is tested according to the national standards in China the error would be high. In view of the accuracy of the observed data, the paper has made a qualitative analysis of factors which affect the quality of observation in the process of actual testing, and points out the reasons for these er rors. The paper has proposed measures for reducing errors and obtaining accurately the parameter of gas content. New suggestions are made for accurate testing of gas content.
