Control Mode of Fault on the Buried-Hill Tectonic Zone of Kendong-Chengdao

Kendong-Chengdao region buried-hill tectonic zone formation mechanism and accumulation difference was unclear. The buried-hill tectonic zone faulting characteristics and mode for the control mountain had been systematically studied. Studies had shown that originated in NW of indosinian to the basement fault controlled the formation of buried-hill tectonic zone. Originated in NE of the Late Jurassic to the basement fault tectonic zone divided into Kendong, GuDong, changti and chengdao four relatively independent buried-hill;Different direction of the basement faults in paleogene tensile stress field in NS under action of the resurrection, controlling the structure of the pattern of buried-hill f tectonic zone. The number activity style and activity intensity of the boundary fault, controlled the height difference of different-buried hill. Accordingly, the establishment of a single break-low convex type, double break-convex type and multi broken-high convex type in three kinds of fault mode control mountain, it had been clear about the different types of buried-hill reservoir in paleogene filling style, sedimentary system and reservoir assemblage characteristics.
