    摘要:

    作为准噶尔盆地腹部较早开发的地区之一,近年来在滴南凸起下白垩统及白家海凸起-阜北斜坡区的中上侏罗统地层内相继发现了高产油气藏,揭示了该区中上侏罗统-下白垩统具有良好的生、储、盖成藏条件,丰富的圈闭类型和有效的疏导体系。在成藏条件上,东道海子凹陷、阜康凹陷的石炭统、二叠系平地泉组以及侏罗系的八道湾组、三工河组、西山窑组等多套烃源岩为侏罗-白垩系成藏提供了充足的油气,河流、三角洲沉积体系控制下的中上侏罗统头屯河组、齐古组以及下白垩统的清水河组、呼图壁河组分布有多套有效的储盖组合,长期继承性的断裂系统及砂体和不整合面作为油气的疏导体系,在成藏条件分析的基础上总结了滴南凸起-阜北斜坡地区3种油气成藏模式。

    Abstract:

    As one of the early developed area in central Junggar Basin, in recent years, the Lower Cretaceous in Dinan swell and the middle–upper Jurassic formation in Baijiahai swell-Fubei slope area have found the high-yield oil and gas reservoirs, reveals that the area of the upper-middle Jurassic and Lower Cretaceous have good source-reservoir-cap reservoirSforming conditions, rich types of trapsSand effectiveScarrierSsystem.SIn theSreservoir forming conditions, SA number of suites of Carboniferous, Pingdiquan formation of Permian andS Badaowan formation,SSangongheSformation,SXishanyao formationSofSJurassic Ssource rocks in Dongdaohaizi and FukangSdepression provide plenty ofSoil and gas to the upper-middle Jurassic and Cretaceous hydrocarbon accumulation, Toutunhe and Qigu formation of the upper-middle Jurassic,Qingshuihe and Hutubihe formation of Lower Cretaceous which are controlled by river and delta sedimentary system have a number of suites of good reservoir-seal assemblage, Sinherited and developed fault system and sand,unconformity are used to be the carrier system of oil and gas,SbasedSon the analysis ofSreservoir forming conditions, summarizesSthree Shydrocarbon Reservoir Modes in Dinan swell-Fubei slope area.
