中文摘要	为查明准噶尔盆地阜康西区块中侏罗统西山窑组煤层控气地质作用,依据区域性水文地质边界池钢逆断层,将区块划分为2个构造单元,依据甲烷风化带、水文地质条件划分出煤层气富集单元。在对研究区构造特征和水文地质特征进行分析的基础上,探讨了构造-水文地质耦合控气机制。研究结果表明,阜康西区块西山窑组煤层气富集是构造-水文地质耦合作用的结果,构造运动使煤层发生动力变质作用与深成变质作用,有助于热成因气生成;燕山运动晚期与喜马拉雅运动期水平挤压运动产生的封闭性褶皱和逆冲断层有助于煤层气保存,燕山运动早期构造抬升不利于原生生物成因煤层气保存;地下水侧向补给至高矿化度滞留区,煤层气因水力封堵作用而富集。而中浅部西山窑组煤层埋深小于600 m的斜坡带则由于构造抬升、较强的季节性径流和蒸发,导致煤层气逸散,同时气候干旱导致的高矿化度地层水抑制次生生物成因气生成,煤层气含量相对较低。
英文摘要	In order to understand the geological gas-controlling functions in the coalbeds of the Middle Jurassic Xishanyao formation in western Fukang block, Junggar basin, the block is divided into 2 structural units according to the regional hydrogeological boundary--Chigang reverse fault and CBM-rich units are classified based on methane weathering zone and hydrogeological conditions. Based on the analysis of structural and hydrogeological features, the paper discusses the coupled structural-hydrogeological gas-controlling mechanism. The study results show that the enrichment of CBM in the Xishanyao formation of western Fukang block should be the product of the coupled functions of structure and hydrogeology conditions. Tectonic movements resulted in dynamic metamorphism and plutonic metamorphism in coalbeds, which are helpful for the generation of thermogenic gas; the sealed folds and thrust faults resulted from horizontal compression in the late Yanshan movement and Himalayan movement contributed to CBM preservation, whereas the tectonic uplift in the early Yanshan movement was not conductive to primary biogenic gas preservation; CBM accumulation by hydraulic seal occurred due to the lateral charging of groundwater into the stagnation areas with high salinity. CBM losses in the coalbeds with the burial depth lower than 600 m in the middle-upper Xishanyao formation were caused by tectonic uplift, relatively strong seasonal runoff and evaporation. Meanwhile, high-salinity formation water due to arid climate restrained the generation of secondary biogenic gas, resulting in the low content of CBM.
