介绍了煤层气藏和页岩气藏形成的基本原理,以及用于评价煤层气藏和页岩气藏的关键数据及其获取方法。概述了这些气藏的钻井、完井及开采过程。在煤层气藏中,天然气地层储量绝大部分被认为是吸附气;页岩气则是吸附气和游离气的混合体,其普遍依赖于水力压裂来连接井筒与天然裂缝。煤层气藏与页岩气藏都具有强烈的非均质性,两种气体将在世界能源供给中占有越来越重要的地位。 The basic principles of the formation of CBM reservoirs and shale gas reservoirs, as well as the key data used to evaluate the CBM reservoirs and shale gas reservoirs and the methods for obtaining them are introduced. Outlines the drilling, completion and recovery processes for these reservoirs. In CBM reservoirs, the vast majority of natural gas reservoirs are considered as adsorbed gas. Shale gas is a mixture of adsorbed gas and free gas. It generally relies on hydraulic fracturing to connect wellbores with natural fractures. Both CBM and shale gas reservoirs have strong heterogeneity, and both gases will occupy an increasingly important position in the world energy supply.
