南川地区浅层常压页岩气吸附解吸机理与开发实践OA北大核心CSTPCD
Adsorption and desorption mechanism and development practice of shallow normal pressure shale gas in Nanchuan area
中国浅层常压页岩气勘探开发尚处于探索阶段,目前在四川盆地及周缘地区实施的多口浅层页岩气井钻遇含气层显示良好,初步揭示了浅层页岩气具有较大的勘探开发潜力.但浅层常压页岩中天然气的赋存状态以吸附气为主,勘探开发面临吸附解吸规律不清、针对性排采工艺尚待建立等问题.为此,以重庆市南川地区武隆区块常压页岩气田为对象,选取不同埋深条件下的岩心样品,开展了页岩储层评价与室内等温吸附实验,基于等温吸附曲线,建立了浅层页岩气吸附解吸模型并划分了吸附气 3 个解吸阶…查看全部>>
Exploration and development of shallow normal pressure shale gas in China is still in the exploratory stage.Currently,multiple shallow shale gas wells in the Sichuan Basin and its periphery have encountered gas bearing layers with good shows,which reveals the significant exploration and development potential of shallow shale gas.However,the shallow normal pressure shale gas is mainly in the occurrence state of adsorbed gas,and its exploration and development…查看全部>>
