摘要
针对页岩特殊的储层条件,优选出含气页岩储层关键参数,并建立页岩气测井评价流程。围绕目标区页岩岩心实验分析结果,提出页岩储层"六元"体积模型,并分别建立了矿物组分评价模型、物性参数评价模型、地化参数评价模型以及含气量评价模型,进行页岩岩石力学分析和可压裂性分析,探讨了页岩储层综合选层思路。并对实际测井处理解释结果应用效果进行分析,证明所建立的测井评价方法在页岩气测井评价中具有较好的推广应用价值。
Aiming at the special shale reservoir conditions, the key parameters of shale gas reservoir were optimized and the shale gas logging evaluation process was established. According to the shale core test analysis results of the target area, the ＂six ele- ments＂ volume models of shale reservoir were proposed, the mineral composition evaluation model, the physical parameter evalua- tion model, the geochemical parameter evaluation model and the gas content evaluation model were established to carry on the shale rock mechanics analysis and the fracturing feasibility analysis, and the comprehensive layer selection ideas of the shale reser- voirs were discussed. Meanwhile, by the application effect analysis of the actual well logging interpretation results, this logging eval- uation method was proved to have great popularization and application value in shale gas logging evaluation.
