摘要
通过对全球页岩气的资源量、分布状况、勘探开发技术研究现状的分析,指出页岩气的资源评价、储层评价、裂缝预测、储层改造、水平井钻采工艺等是当前国际页岩气勘探开发技术研究的热点。当前和未来国际页岩气研究将主要关注:页岩气成因机理研究、成藏机制探讨、有效页岩气层识别、页岩气产层压裂改造、水平井和多分支井等技术。我国页岩气研发总体还处在起步阶段,当前主要任务是进行资源量评价和有利目标区域优选,以及开展关键技术的试验先导性研究。我国今后需要进一步加强页岩气成藏机理和模式研究、加大对页岩气勘探开发相关技术研究、深入开展页岩气开发先导性试验、加大国家政策对页岩气研发的支持力度以及加强国际交流与技术合作。
The reserve,the distribution as well as the status of exploration and exploitation technologies were systematically investigated.It has become an international hot research field for the technologies of shale gas resource evaluation,reservoir identification and evaluation,fracture prediction,reservoir reconstruction,horizontal well drilling process and so on.The current and future focus of the shale gas will be concerned as follows：shale gas formation mechanism study,the mechanism of accumulation,the effective identification shale gas,shale gas producing formation fracturing,horizontal wells and multilateral well technology.China＇s shale gas development in general is still in its infancy,the current main task is to evaluate the amount of resources and a favorable target area preferred,as well as key technology to carry out experimental pilot study.China need to further strengthen shale gas accumulation mechanism and mode of study,to increase technology research of shale gas exploration and development,to development pilot projects,to increase the national policy on R D support and to strengthen international exchange and technical cooperation.
