THE RELATION BETWEEN STRUCTURAL EVOLUTION AND HYDROCARBON MIGRATION AND ACCUMULATION OF KONGQUEHE SLOPE IN TARIM BASIN

The research method of combining the structural evolution with hydrocarbon accumulation has important directive function for oil gas exploration in Kongquehe slope of Tarim Basin. We have concluded that the structural movement of the area can be divided into three stages: The stretching stage from Simian to early Ordovician, the extrusion and rising stage from middle and late Ordovician to Jurassic and stable depressed stage of foreland basin slope from Cretaceous to Neozoic. Structural which has controlled many factors, such as the development of oil generation, source rock, cap rock and the fault, is the main control factor of hydrocarbon migration and accumulation. Finally, through comparison and analysis, we believe that Weimake-Kaiping and Longkou structural belts possess better potential for exploration.
