Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态，充填叠置方式、演化及沉积体系分布的最重要因素：凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成；受断层控制，层序外部形态有箱状-楔形、楔形-席状披覆型，边界终止方式有双断终止型、单断终止超覆型；不同构造演化阶段层序内部充填的沉积体系各具特征，初始断陷阶段的SQ1沉积冲积层序，强烈断陷阶段的SQ2-SQ4充填湖相层序，晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积；同沉积断层陡坡带沉降迅速、可容纳空间快速增长，是凹陷的沉积和沉降中心，断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。

The Triassic structure in the east part of North Shaanxi Slope of Ordos Basin is a large smooth westward monocline and characterized by simple structure without folds and faults.

陕北斜坡东部三叠系构造简单，为平缓的西倾单斜，断裂褶皱均不发育，因此该区三叠系油藏的形成和分布一直被认为主要受沉积相控制，油藏类型主要为岩性油藏。

The result indicates that Chang 6^2 is a delta-lacustrine depositional system, and the principal producing pay is in subaqueous distributary channel where deposit fine sandstones and have good physical properties. The areas in the center of subaqueous distributary channel get high oil-produce while the flanks gel lower oil-produce relatively. The distribution of oil layer is mainly controlled by lithology, and Chang 6^2 is lithologic reservoir developed in the monocline setting which clime to the northwest.

研究表明：长6^2储层为三角洲－湖泊沉积体系，主要产油层位于长6(上标 2-2)的水下分流河道中，沉积细砂岩且物性较好，河道中心地区的产油量相对较高，而河道侧翼地区的产油量相时较低：长6^2中的油层分布主要受岩性控制，是在北西倾料的单料背景上发育的岩性油藏。

But the geological and geochemical analyses showed that there existed a set of high quality marine source rock in the platform slope facies of Middle Ordovician Pingliang Formation. The oil and gas generated from the source rock of Pingliang Formation was accumulated firstly in the central Palaeo-uplift and its surrounding regions. The thermogenic asphalt in palaeo-uplift carbonate reservoir indicated that oil accumulation completed transition from oil to gas in the Lower Crataceous. Along with the palaeo-uplift axis convection and the formation of westward monocline in the Late Crataceous, gas from the palaeo-reservoir was finally accumulated in the weathering crust of Majiagou carbonate reservoir.

地质和地球化学分析证实，盆地西、南缘台缘深水斜坡相的中奥陶统平凉组存在优质海相烃源岩，其形成的油气最早富集在中央古隆起及其周围；伴随着中央古隆起带轴部的向东迁移和早白垩世末盆地西倾大单斜的定型，平凉组烃源岩在早白垩世生烃高峰期生成的天然气和早期古油藏裂解气，由中央古隆起带向北东方向发生二次运聚，最终在盆地中部奥陶系马家沟组风化壳中聚集成藏，即形成靖边大气田。
