Abstract: Shin Ginning Basin is a large composite basin. It under went through midlate Proterozoic to early Paleozoic continental sea, late Paleozoic transition and Mesozoic-Cenozoic continentil lacustrine depositional stages, and many kinds of source socks of oil and gas are developed. Within this basin oil and gas traps in Mesozoic are mainly subtle pools, and mainly structural gas pools in Paleozoic. It can be devided into five accumulation regions of oil ind gas. There are not only the conditions of forming the oil and gas pool in large Mesozoic continental facies basin, but also a rich potential of nituural gas in Paleozoic marine facies and transitional ficies formations. With a wide exploration field, this basin is probably one of the important strategic areas for natural gas explorations.

摘要： 陕甘宁盆地是一个大型叠合盆地,它经历了中晚元古代——早古生代陆表海,晚古生代海陆过渡以及中新生代内陆湖相沉积阶段,发育多类型油气源岩。盆地的油气圈闭,中生界以隐蔽型油藏为主,古生界为构造型气藏,可划分出五个不同类型的油气聚集区,既具备甲生代大型陆相盆地油气藏形成条件,又海相、海陆交互相地层天然气资源丰富,勘探领域广阔.
