北美地区页岩气开发已经商业化,开发技术也逐步趋于成熟,而中国虽然有丰富的页岩气资源,但由于起步较晚,目前还处于探索阶段.有效开采页岩气通常需要在水平井中实施大规模的多级水力压裂,提出了低渗油气藏大规模水力压裂的关键岩石力学原则,介绍了微地震技术在水力压裂监测中的应用,并用离散单元法建立的数学模型对水力压裂的效果进行了评价,分析了中国页岩油气藏水力压裂方案优化的地质因素,并对大规模水力压裂的可持续性发展提出了一些建议.

Production of gas and hydrocarbon liquids from low permeability shales has been established in North America; exploration and development has accelerated in Europe and in China, and generic opportunities in China are postulated. Currently,effective production requires multiple hydraulic fracturing stages usually in horizontally drilled wells. Key geomechanical principles relating to the response of these reservoirs to large volume hydraulic fracturing are presented. Geologic reasons why hydraulic fracturing treatment schedules may need to be refined for some shale plays in China are outlined. Finally, from a longer-term perspective, sustainability of these large volume treatments is considered and modifications and alternatives are suggested.
