摘　　要：本文以新疆阜康白杨河示范区为研究对象,基于研究区煤储层渗透率好、煤层厚度大的特殊性,依据钻井取心解吸实测数据,结合测井资料分析研究影响煤层气储层含气、孔渗特征的地质因素,建立研究区煤层气富集与开发的地质评价体系,进行研究区煤层气富集高产研究。研究表明研究区的东部和西部为煤层气富集高产区,中部相对较弱,研究区呈现高产-低产-高产-低产的交替规律,且与产能展布具有良好相关性。In this paper,Baiyanghe demonstration area in Fukang,Xinjiang is taken as the research object.Based on the particularity of good permeability of coal reservoirs and large thickness of coal seams in the study area,according to the measured data of drilling coring and desorption,and combined with the logging data,the geological factors affecting the gas content and porosity and permeability characteristics of CBM reservoirs are analyzed and studied.The geological evaluation system for CBM enrichment and development in the study area is established,and the enrichment and high yield of CBM in the study area is studied.The study shows that the eastern and western parts of the study area are rich in coalbed methane,and the central part is relatively weak.The study area presents the alternating law of high-yield-low-yield-high-low-yield,and has a good correlation with productivity distribution.
