齐古断褶带中部煤层气储层特征及成藏模式研究
Study on Coal Bed Methane Reservoir Characteristics and Accumulation Model in the Middle of Qigu Fault-fold Belt
摘要
Abstract
Complex geological structure of southern margin of Junggar Basin is one of the main factors affecting the coalbed methane (CBM) development work,in order to grasp the uniqueness of CBM accumulation pattern in small area,based on the middle Qigu fault fold belt of more than 200 km2,according to its regional tectonic characteristics and hydro-geological characteristics and coal quality characteristics,combined with the related units of drilling,logging,and coal sample analysis,isothermal adsorption and other data and literatures,we analyze and evaluate reservoir characteristics of coal seams in the study area on the control function of production and storage of coalbed methane,and set up the regional accumulation pattern of coalbed methane,namely the homocline accumulation mode and broad and gentle fold accumulation mode.By analyzing gas bearing area and coalbed methane storage capacity from two kinds of accumulation patterns,we think that broad and gentle fold accumulation model is superior to homocline accumulation model.关键词
