油气资源的紧缺是一项世界性的难题。油气资源对世界经济发展而言具有不可替代的作用,而作为不可再生资源,其应用的范围越广,就会越快地迎来资源耗尽的问题。而页岩气作为非常规的油气资源之一,其存在对于世界日渐枯竭的能源资源而言是一个强有力的补充。本文从页岩气的相关概念入手,分析页岩气成藏过程和储存状态,对页岩气储存研究现状与其矿物成分、化学特征、物性特征、储集空间特征以及含气性特征进行分析,指出我国对页岩气研究存在的各种问题,为页岩气研究的发展提供建议,促进我国页岩气研究的发展。
The shortage of oil and gas resources is a worldwide problem. Oil and gas resources play an irreplaceable role in the world economic development. As the non-renewable resources, the wider their application, the sooner the problem of depletion of resources will be met. As an unconventional oil and gas resource, shale gas is a powerful supplement to the world’s depleted energy resources. This paper starts with the related concepts of shale gas, analyzes the process of shale gas accumulation and its storage status, analyzes the status of shale gas storage and its mineral composition, chemical characteristics, physical properties, reservoir space characteristics and gas-bearing characteristics, It points out various problems in shale gas research in our country, provides suggestions for the development of shale gas research and promotes the development of shale gas research in China.
