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。

When the gas reserves of the gas cap are relatively bigger, the gas cap and the oil column should be exploited simultaneously. When the volume of the gas cap is relatively smaller and the energy of the edge and bottom water is sufficient, the oil column should be exploited first depending on the natural energy, then water injection should be done artificially, and the gas cap should be exploited at last.
