胡状集北部沙一下段盐岩沉积与油气分布规律研究

运用层序地层学的方法,利用地震岩性反演手段,对东濮凹陷胡状集北部沙一下段盐岩透镜体形成古环境、盐湖层序结构模式以及盐岩透镜体所在区域油气分布规律进行了研究.结果认为：岩性透镜体是湖泊中心或斜坡带底部发育的盐类扇体,其盐间薄层白云岩、泥质白云岩和砂岩为有利的勘探目标;对研究区寻找隐蔽油气圈闭具有重要的指导意义.

Salt deposition and oil distribution study in the north of Huzhuangji

This article utilizes the method of sequence stratigraphy and seismic lithologic inversion to study the ancient environment of salt lens,salt lake sequence structure,and oil and gas distribution in the lower Sha-1 member of the north of Huzhuangji in Dongpu depression.The result is that the lithologic lens is the salt fan grown in lake center or pitch belt base,and the thin dolomite, shaly dolomite and sandstone in the salt lens are the advantageous exploration goals.These have an important guiding sense to seek the subtle trap in the research area.
