摘要
由于我国页岩气勘探开发仍处于不成熟阶段,页岩气资源评价需用多种方法。通过对目的层段的钻井取心及对取心资料的地球化学分析、X衍射资料、扫描电镜等资料分析,结合研究区页岩气成藏条件,基于有机质丰度、有机质成熟度、泥页岩厚度、埋深和地表条件等5方面,建立了页岩气远景区、有利区和目标区优选参数体系,并采用概率体积法计算出了其地质资源量。研究发现梨树断陷页岩气丰富,具有巨大的勘探潜力。
Restricted by shale gas exploration in immature period of our country, resource assessment methods of shale gas are various. According to the core and relative geochemistry analysis, X-diffraction and SEM （ scanning electron microscope） data of the target straturm in combination with reservoir forming conditions, this paper estab-lished preferentially selection parametric system of shale gas prospective areas, favorable areas and target areas in Lishu depression based on abundance, maturity of organic materials, thickness of mud shale depth and surface con-dition, and conditional probability principle was adopted to calculate geologic resource. The study showed abundant shale gas in Lishu depression, suggesting enormous exploration potentiality.
