煤层气资源开发现状及测井技术攻关方向

Resources Development Status and Research Direction of Logging Technology in Coalbed Methane Industry

综述国内外煤层气资源量和勘探开发历史和现状。世界上煤层气资源潜力巨大,是值得重视的天然气后备资源。在煤层气的勘探开发过程中,煤层气储层特征的独特性使得常规地球物理测井评价在资料采集、基础理论和解释方法、三维储层精细描述等方面存在不适用性。测井技术的进一步发展需要在测井新仪器研发、测井解释新理论和方法、测井新技术应用和井间地球物理技术等几个方面深入攻关。

The coalbed methane resources, their history and present situation of exploration and development at home and abroad are summarized. It shows that the resource potential of combed methane in the world is huge and worthy. In the processing of exploration and development, the unique of reservoir characteristics makes normal log evaluation inapplicable in several aspects as data acquisition, theory and interpretation method, 3D fine reservoir description and etc. So it is necessary for further development of well logging technology that the following aspects need research as new logging instrument development, new log interpretation method, new logging technology application and borehole geophysical technique, which lay a good foundation for increasing the reservoir evaluation precision of cnoalbed methane.
