PARAMETERS AND FLOW CHART FOR COALBED METHANE POOL ANALYSIS

摘要: 煤层气藏特有的赋存状态、圈闭形式和不均一性决定了煤层气藏分析在煤层气勘探乃至开发中的重要地位.煤层气资源条件、煤储层岩石的不均一性程度是煤层气藏分析的重要方面.煤层气藏的分析评价应适应煤层气勘探开发的进程.在勘探初期评价选区阶段应以煤层气藏的地质条件分析为主.在进入井网试采阶段应突出煤层气藏分析, 特别是煤层气藏的不均一性分析.Abstract: The occurrence state, trapping pattern and heterogeneity characteristic of the coalbed methane pool contribute to the important role of the coalbed methane pool analysis in the coalbed methane exploration and development. The conditions of the coalbed methane pool and the heterogeneity of the rock in the coal reservoir are both important aspects of the coalbed methane pool analysis. The analysis and assessment of the coalbed methane pool should meet the needs of the progress of coalbed methane exploration and development. In the initial exploration, the evaluation of the chosen exploration region should be dominated by the analysis of the geological conditions of the coalbed methane pool. However, the sampling drilling of the well network should be dominated by the analysis, especially by the heterogeneous analysis, of the coalbed methane pool.
