摘要
In this paper, rock constituents of high GR reservoirs are analyzed and are compared with these of nonreservoirs.T he genesis factors of high GR reservoirs are concluded as the increase of pyroclastics, the change of clay types and the absorption effect of clay particles. With the study, two methods, Pe-GR cross plot analysis and volume model are used to interpret these high GR reservoirs. This study established effective solutions for high GR reservoir identification.
