摘要： 准噶尔盆地油 气资源丰富勘探程度低,勘探潜力巨大。南深北浅 的楔形地质结构与区域单斜形态决定了盆地腹部中浅层侏罗_白垩系主要发育低幅度背斜.断裂.岩性体、地层.岩性等非构造油气藏.这是油气勘探的现实领域;南缘强烈的冲断活动与压扭作用形成的复杂叠加构造带是油气勘探的战略突破领域:被晚期深埋的腹部石炭系_三叠系大构造则是重要的战略接替领域。准噶尔盆地的油气勘探具有多个油气储量增长高峰的特点.近10年来非构造油气藏、中深层油气藏的储量发现大幅度攀升。非构造油气藏已成为勘探的主要对象，

Abstract: Junggar basin is one with abundant hydrocarbon resources,low degree of exploration and great potentials for oilprospecting. For further petroleum exploration, its wedge-like structure with shallow or thin strata in the north and deep or thickstrata in the south and regional monoclinal structure would be the realistic domains by their determinants for the fact that thesubtle trapping oil-gas reservoirs such as low -amplitude anticline,faulting-lithologic and stratigraphic-lithologic types are primarilydeveloped in middle- and shallow. -buried Jurassic-Cretaceous in the hinterland of Junggar basin; its complex superimposed struc-tural belts shaped by intense thrusting and compresso-shear actions would be the strategic breakthrough domains; while the deep-buried large -scale structures of Carboniferous to Triassic in hinterland of the basin should be the important successive domains. Inaddition, Junggar basin has a characteristic of multiple incremental peaks in oil-gasreserves or OOIP/OGIP. In recent 10 years,much more reserves have been found out from the subtle reservoirs and the middle-deep reservoirs.Hence subtle reservoirs havebecome major targets for further hydrocarbon exploration in Junggar basin.

Key words: Junggar basin, oil-gas field, exploration, play, structure, trap
