摘要
Sand bodies,reservoir physical properties and source rocks are the most important key factors for hydrocarbon accumulation. On the basis of fully analyzing the petroleum geological characteristics in the Cangdong sag,sand body evolution index(Isb),reservoir property evaluation index(Irp),source rock evaluation index(Isr) and three factors evaluation index(Itf) of every lobe are established to compose a complete evaluation system.The result shows that the Cangxian system of delta-offshore subaqueous fans,Shenvsi delta,the Kongdian system of delta-offshore subaqueous fans and the Yesanbo delta are the most favorable oil-gas exploration targets.
