摘　　要：水力封堵型煤层气藏有着自身独特的性质,是最常见的煤层气藏边界,对其深入研究有助于总结受水力影响煤层气富集地区的规律,丰富地质学理论。文章对国内外各类型水力封堵型煤层气藏分析的基础上,根据气藏区域构造特征和岩性特征,将水力封堵型煤层气藏分为两类六型,即构造类:单斜型水力封堵煤层气藏、向斜型水力封堵煤层气藏、断层型水力封堵煤层气藏,以及复合类:水力封堵-物性型煤层气藏、水力封堵-岩性型煤层气藏和水力封堵-断层型煤层气藏。The unique characteristic of the hydraulically sealed type CBM reservoirs is the most commonly found CBM reservoir boundary. To-the-depth study of the characteristic will help us to summarize the rules of CBM enrichment area hydraulically sealed,and will enrich the geology theory. The paper divides the hydraulically sealed CBM reservoirs into two categories and six types based on all types of hydraulically-sealed CBM reservoirs at home and abroad and based on tectonic characteristics and rock types of gas reservoirs：i.e. tectonic category,and composite category. The tectonic category is subdivided into monocline type hydraulically sealed CBM reservoir; syncline type hydraulically-sealed CBM reservoir; fault type hydraulically-sealed CBM reservoir. The composite category is subdivided into hydraulically sealed-physical property type CBM reservoir,hydraulically-sealed rock type CBM reservoir,and hydraulically sealed fault type CBM reservoir.
