摘要
通过对新疆阜康白杨河矿区急倾斜煤层岩石物理特征、储层裂隙系统特征、煤层水特征的研究,发现本区煤层水垂向分带特征明显,气水分异程度比较高。对比研究了本区和沁南盆地煤层水赋存特征和可采性,认为本区可采性优于沁南盆地。在煤层气井排采实例分析的基础上,对本区煤层气藏开发的井型、钻井、压裂和排采等工程技术给出了指导建议。
Focused on petrophysical characteristics, large fracture system and coalbed water characteristics of steep coal seam, discovered that the coalbed water characteristic of vertical zonging is obvious and the gas and water differentiation degree is higher. To comparative study the characteristics of coalbed water occurrence and workability in study area and the south of Qinshui basin, and offer some proposals about selection well type, well drilling, hydraulic fracturing and drainage process.
