摘要
煤层气富集成藏受煤储层地质特征的制约。通过对大量实验测试数据的分析与对比,研究了乡宁矿区煤层气成藏基础地质特征,主要包括煤储层发育特征、煤岩学特征、煤化学与工艺特征及煤级与煤相特征等。结果表明,本区主要煤层煤空间展布稳定、累计厚度大、煤质好、热演化程度高,具备煤层气成藏的基础条件。
Coalbed methane(CBM) reservoirs is greatly affected by geological characteristics of coal seams.Based on analysis of a large number of experimental test's data,we study the geological properities of coal reservoir which include 3D of coal seams,coal petrology,coal chemistry,coal's process feature,coal rank and coal facies,et al.The results showed that the key coal seams are stable spatial distribution,the cumulative thickness is huge,coal quality is good and has a high degree of thermal evolution.It has a very good basic conditions for coalbed methane reservoir.
