Abstract:
The east of the southern fringe of Junggar basin Uygur Autonomous Region of Xinjiang is an important oil and gas exploration region in Junggar basin. The forming conditions of the reservoirs are studied, the patterns of the reservoirs are established and the potential of hydrocarbon resources is predicted with the techniques of basin analysis, effective source rock evaluation, reservoir prediction, basin modeling and fluid inclusion with the theories of basin evolution, hydrocarbon generation, and reservoir formation. It is demonstrated that the three source rocks of Upper Permian, Upper-Middle Triassic, and Middle-Lower Jurassic are developed in this area with Upper Permian as the main source rock and the main zone of hydrocarbon resources. The main reservoirs are the Upper Permian of Chaiwopu Block, and Middle-Lower Triassic and Middle-Lower Jurassic of Miquan Block with rather poor petrophysical properties, being a good gas-bearing reservoir as a whole, and the main exploration target for hydrocarbon. There are two types of patterns of reservoirs, i. e., self source-lateral expulsion of hydrocarbon, and external source-vertical expulsion of hydrocarbon;the northern part of Chaiwopu sag and Miquan Block is still a favorable oil and gas exploration region in the east of the southern fringe of Junggar basin.
