摘要: 通过对页岩层系发育的时代、沉积特征、演化历史、现今所处的大地构造位置、构造特征、页岩残留状况、分布特征、埋深和含气量等因素的综合考虑,根据"单源一位"页岩气成藏体系划分的一般性原则,将四川盆地及其周缘上奥陶统-下志留统页岩气成藏体系划分为川南-川东南、黔北、渝东、湘鄂西、龙门山、米仓山-大巴山和川中7个成藏体系,描述了不同成藏体系中页岩层系的厚度、有机碳含量、成熟度和含气量等特征,并按战略展开区、战略突破区、战略准备区和战略远景区4个层次对成藏体系进行了评价,明确了勘探层次.Abstract: Shale sedimentary time,feature,evolution history,present tectonic location,tectonic feature,residual condition,distribution,burial depth and gas content were discussed in this paper.The accumulation system for shale gas from the Upper Ordovician to the Lower Silurian in the Sichuan Basin and the surrounding areas was divided into 7 accumulation systems,including the southern and southeastern Sichuan,the northern Guizhou,the eastern Chongqing,the western Hunan and Hubei,Longmen Mountain,Micang Mountain-Daba Mountain,and the central Sichuan.Shale thickness,organic carbon content,maturity and gas content in each accumulation system were analyzed.The accumulation systems were evaluated at 4 levels as followed: strategic breakthrough,expansion,preparation and perspective area.Exploration targets were also pointed out.
