通过分析和顺区块15号煤层厚度、埋深、煤岩煤质特征、演化程度、煤层含气性及吸附性、煤储层物性、煤层气保存条件等煤层气成藏影响因素，认为和顺区块煤层气成藏条件具有煤层厚度大、分布面积广、含气量高，煤储层裂隙发育、保存条件好、水动力条件优越等特点，是沁水盆地15号煤层煤层气勘探的有利目标区。
通過分析和順區塊15號煤層厚度、埋深、煤巖煤質特徵、縯化程度、煤層含氣性及吸附性、煤儲層物性、煤層氣保存條件等煤層氣成藏影響因素，認為和順區塊煤層氣成藏條件具有煤層厚度大、分佈麵積廣、含氣量高，煤儲層裂隙髮育、保存條件好、水動力條件優越等特點，是沁水盆地15號煤層煤層氣勘探的有利目標區。

It is proved that the coalbed methane enrichment conditions of Heshun block are favorable by analyzing the influencing factors like coal seam thickness, buried depth, coal quality characteristics, evolutionary degree, coal seam gas content and adsorb-ability, coal seam property and coalbed methane storage conditions, which have the characteristics of large coal seam thickness, wide distribution area, high gas content, developed coal seam fracture, great storage conditions and fine hydrodynamic conditions. It shows that Heshun block is the favorable target area of the coalbed methane exploration of 15# coal seam in Qinshui basin.
