摘要
页岩气分布广泛,开发潜力巨大,但是页岩气成藏规律、储集空间、渗流规律以及开发模式有其自身的特点,特别是储层具有低孔特征和极低的基质渗透率,给有效开发带来很大的困难和挑战。本文从介绍页岩气的概念、成藏机理及储层特点出发,重点总结了目前页岩气的主要开发技术及存在的问题,并分析了我国页岩气开发适应性技术,对开展页岩气开发技术的研究有一定的指导意义。
Shale gas has a wide range of distribution and great potential for exploration, but the shale gas has its own characteristics on the accumulation rule, reservoir space, seepage rule and the development mode, especially the reservoir with low porosity and very low matrix permeability that has brought a lot of difficulties and challenges for effective development. This paper not only introduces the concept, accumulation mechanism and reservoir characteristics of shale gas, but also mainly summarizes the current main development technologies and existing problems as well. The shale gas development technologies which are suitable to China are analyzed and hope the research results on the shale gas development technology is of certain guiding significance.
