非传统资源所产生的天然气(如煤层气)现已成为普遍的开采对象,ASTM一项新标准提出了使用地面钻井取样解吸法测定煤中气体含量的方法。ASTM D 7569煤层气含量的检测方法实践规程一直接解吸法,由ASTM D 05煤和焦炭技术委员会下属的D 05.21分析方法分会负责制定。此标准将为政府、行业和研究实验室建立
Natural gas (such as CBM) from non-traditional sources is now a common source of exploitation and a new ASTM standard proposes a method for the determination of gas content in coal using Ground Drilling Sampling and Desorption. ASTM D 7569 Method for the Detection of Coalbed Methane Content Practice A direct desorption method was developed by the ASTM D 05 Coal and Coke Technical Committee Subcommittee on D 05.21 Methods. This standard will be for government, industry and research laboratories
