煤层甲烷气藏的现代化评价技术

The Current State of the Techniques Evaluating Coalbed-Methane

论述了用于评价煤层气藏开发远景的储藏评价技术。对煤层气藏进行评价的各种不同类型评价方法都曾经历了长期的技术演变与改进完善 ,其中包括岩心评价、测井、地震勘探、不稳定压力测试与生产分析。介绍了目前正在投入矿场应用的评价方法和近几年研究推出的具有先进技术水平的评价方法。具有先进技术水平的评价方法有一部分尚处于深入研究开发阶段 ,有一部分将会被石油工业界业内人士接纳 。

This paper focuses on the reservoir evaluation techniques that are used to assess coalbed-methane development prospects. A variety of reservoir-evaluation methods specific to coal reservoirs have evolved over time,including core evaluation,well logging,seismic,transient-pressure testing and production analysis.This paper addresses current methods and newer,state-of-the-art methods that are under development and becoming more accepted for use in evaluating coalbed reservoirs.
