介绍了基于国际通用准则"石油资源管理系统"(PRMS)的各级煤层气资源/储量的定义及分类要求,从资产所有权、政府监管与项目审批条件、井控程度、测试程度、基础设施和销售市场、开发与生产时间以及经济参数这7个方面详细分析煤层气各级储量的划分依据。结合煤层气地质条件和工程条件、现行经济条件、操作条件以及政府相关政策等,初步制定了煤层气3P储量和条件储量的确定原则并进行实例分析,为合理评估煤层气储量提供重要参考。

This paper introduces a set of definitions and classification requirements for coalbed methane (CBM) resources/reserves based on the Petroleum Resources Management System (PRMS).General requirements for the classification of CBM reserves are outlined from seven perspectives: ownership considerations, governmental regulatory and project approval considerations, drilling requirements, testing requirements, infrastructure and market considerations, timing of production and development, and economic requirements.Combined with the geological and engineering conditions, current economics, operating conditions and government policies of CBM, the principles used to classify Proved, Probable, and Possible (3P) reserves and contingent resources were formulated, and demonstrated by a case analysis.These data provide important reference points for the reasonable assessment of CBM reserves.
