摘要
The fault basin in Paleogene has the physiognomy sight of alternating convex and concave, steep low-high relief and volatile ups and downs with multi-sedimentary sourced, narrow facies, multi-genesis sands and sub-structure belts in different scales. These sub-structure belts have a very good matching relationship with different sediment microfacies and different genesis reservoirs, forming various kinds of structure lithofacies belts. Many difficulties have been posed in petroliferous evaluation and exploration in oil and gas because of the much difference in their sedimentary and structure property and the formation condition of oil and gas.
