摘　　要：煤层气属于低渗透非常规气藏,水力压裂技术是提高煤层气井产量的重要措施。根据煤层气压裂改造的特点和难点,依托实验手段对煤岩裂缝延伸规律进行研究,优化压裂液和支撑剂体系,通过现场实验,最终形成了一套针对山西鄂尔多斯盆地煤层气井压裂改造的优化技术。By conventional technology,it is difficult to generate economic benefits from coaled,low permeability gas reservoirs.Hydraulic fracturing is the most important method of increasing production of CBM wells.The article is based on experimental methods of study on regular patterns of fracture extension,as well as the optimization of the fluid and proppant system.Technological research,combined with field trials,has formed optimization techniques in SHANXI CBM wells stimulation.
