摘要
茨榆坨潜山为东部凹陷典型的太古宇潜山。根据区内潜山埋深、构造形态及主要断层的控制作用,可以划分为高、中、低三个潜山带。裂缝型储层是茨榆坨潜山的储集层,良好的储层是潜山成藏的关键。牛居-长滩洼陷为潜山提供了丰富的油源,茨东断层及不整合面做为良好的输导体系,上覆房身泡组火山岩为油气成藏提供了盖层条件。油气分布与岩性、构造有关,且有沿裂缝发育带、近油源分布的特点。
Ciyutuo buried hill is the typical Arohaeozoie buried hill of east sag.According to the depth,structure feature and the controlling of main fault of buried hill,it is divided into high,medium,low buried hill zone.Fracture type reservoir is the reservoir of Ciyutuo buried hill,and good reservoir stratum is the key of buried hill to be deposit.Niuju-Changtan low-lying supplies fruitful oil source for buried hill,Cidong fault and the unconformity of surface is a good conduct system,and Fang-shen-pao group supplies cap rock.Oil and gas distribution relates to rock properties and structure,and has the distribution featur,that is along the fracture development zone and close to oil source.
