摘要
深部煤层取心数据和室内试验数据相对较少,很难有效鉴定煤层煤体结构、显微组分、含气量和渗透率等重要参数,阻碍了煤层气的开发和预测。为了解决这一问题,通过数据统计分析,对比测井资料、实验室测试数据和现场注入压降试井数据并进行分析,以构建目标区块煤层参数测井解释模型,通过这一模型对煤层展开了全面评价。
Deep coal seam coring data and laboratory test data are relatively few,so it is difficult to effectively identify important parameters such as coal structure,maceral,gas content and permeability,which further hinders the development and prediction of coalbed methane.In order to solve this problem,the logging data,laboratory test data and field injection pressure drop well test data should be compared and analyzed through statistical analysis of data,so as to build a logging interpretation model of coal seam parameters in the target block,and then comprehensively evaluate coal seams through this model.
