摘　　要：煤阶类型的准确识别是地球物理测井技术评价煤层气储层的关键。为建立煤岩储层煤阶类型测井识别方法,选取国内各大盆地典型的煤层气储层为研究对象,利用大量的测试化验分析实验与测井资料结果,系统总结了褐煤、长焰煤、气煤、肥煤等8种煤阶类型储层的测井响应特征,构建了不同煤阶类型储层测井响应图版;同时针对煤岩层段井眼状况复杂的实际问题,分析了不同井眼条件下的测井响应特征,建立了不同扩径尺度上识别煤阶类型的测井解释图版。相关结果为煤岩储层煤阶类型的测井识别奠定了基础。Accurate identification of coal rank type is the key to the evaluation of coalbed methane reservoir by geophysical logging technology. In this paper,in order to establish a coal rank type logging identification method for coal and rock reservoirs,typical coalbed methane reservoirs in major domestic basins are selected as the research object,and a large number of test laboratory analysis experiments and logging data results are used to systematically summarize the logging response characteristics of 8 coal rank reservoirs including lignite,long flame coal,gas coal and fat coal. So the well logging response charts of different coal rank types were constructed;At the same time,in response to the practical problems of complex borehole conditions in coal-rock intervals,the logging response characteristics under different borehole conditions were analyzed,and log interpretation plates for identifying coal rank types at different expansion scales were established. The related results laid the foundation for logging identification of coal rank types in coal and rock reservoirs.
