    Occurrence Mechanism and Key Controlling Factors of Wufeng-Longmaxi Shale Gas, Eastern Sichuan Basin

    • 摘要: 页岩气是重要的非常规天然气资源,主要以游离气与吸附气状态赋存于页岩中,研究和阐明其含量、主控因素和演化规律对于揭示页岩气成藏机理具有重要意义.采用不同条件下页岩高温高压等温吸附实验、FE-EM、CO2吸附、N2吸附、压汞等实验方法综合研究页岩气藏中的游离气与吸附气的主控因素.结果表明,游离气主要受页岩孔隙类型、孔隙结构、储层温度与压力等条件控制;OC、成熟度和水分影响吸附气含量.基于吸附气体积校正、地质模型和数值计算综合表征,五峰-龙马溪组页岩中以游离气为主,其平均含量约为%,吸附气含量约为4%.在抬升阶段,储层温度和压力发生改变,页岩气赋存形式随之变化,游离气减少,吸附气增加.
