| 摘 要： | 准噶尔盆地南缘东段是准噶尔盆地油气勘探的重点地区。以成盆、成烃和成藏理论为指导，应用盆地分析、有效烃源岩评价、储层（裂缝）预测、盆地模拟及流体包裹体分析等技术和方法，综合研究分析了准噶尔盆地南缘东段油气成藏条件，预测了油气资源潜力，建立了油气成藏模式。研究结果表明，该区发育上二叠统、中上三叠统和中下侏罗统三套烃源岩。最主要的烃源岩层为上二叠统，是油气资源分布的主要层位；主要储集层为柴窝堡区块的上二叠统和米泉区块的中下三叠统及中下侏罗统，其物性较差，总体为较好含气储层，是主要的勘探目的层。存在自源（侧向排烃）、它源（垂向排烃）两类油气成藏模式。柴窝堡区块北部和米泉区块仍然是有利的油气勘探地区。

| Abstract: | The east of the southern fringe of Junggar basin Uygur Autonomous Region ot 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. |
