乌鲁木齐河东河西矿区煤层气储层特征

Coalbed Methane Reservoir Features of Hedong-Hexi Mining Area,Urumqi

乌鲁木齐河东河西矿区早-中侏罗纪富煤带,聚集着丰富的煤层气资源,笔者通过对该区煤层气赋存的地质条件、储层特征、资源量、煤层气保存条件的专门研究,评价出了有利区块,为下一步煤层气勘探提供了依据。本文主要通过实际采样测试,对该区煤储层的含气性、吸附性、孔隙结构、渗透性等进行了系统研究,探讨本区煤层气有利于勘探开发的储层条件。

There are abundant coal methane resources hosted in early to middle Jurassic coal prolific zone in Hedong-Hexi coal district,Urumqi.The authors find out beneficial blocks through special studies on geological setting of coal methane,reservoir features,resource extent ,retaining condition etc.as a basis of further coal methane exploration.Mainly through site sampling and testing,the paper has made a systematic exposition on coalbed methane-bearing feature,adsorption,porosity and permeability,probed into beneficial reservoir features for coalbed methane exploration and exploitation.
