中国煤层气资源丰富，因此煤层气的勘探与开发具有很强的经济意义、环境意义以及社会效益。煤层气研究方法与准确评估是煤层气高效开发的关键。以华北地区煤层气资料为例，煤层气的选区、选井及选层主要依靠地震勘探技术结合基础地质技术，然后在选区内的井进行数据测量以及按设定所需要的数据进行煤层划分以及煤层识别，测井方法主要有自然伽马测井 GR、深浅侧向测井 LLD|LLS、中子测井 CNL、密度测井DEN、声波时差测井AC及冲洗带电阻率测井RXO。

Coalbed gas resource in China is rich, so exploration and development of the coalbed gas has the very strong economic significance, environmental significance and social benefit. Research methods and accurate assessment of the coalbed gas are the key to efficient development of the coalbed gas. In this paper, taking data of coalbed gas in North China area as an example, block selection, well selection and layer selection of the coalbed gas were carried out by the seismic exploration technology and the basic geological technology, then well data measurement in selected block was carried out to finish the coal bed division and the coal bed identification based on the data. Logging methods mainly include natural gamma logging GR, depth lateral logging neutron logging LLD|LLS, CNL, DEN, acoustic logging, density logging AC and flush zone resistivity logging RXO.
