胡状集北部沙一段地质条件分析及油气分布规律研究
|
摘要
运用层序地层学的方法,利用地震岩性反演等手段,通过对东濮凹陷胡状集北部沙一段地层、构造、沉积等地质条件进行分析以及研究区油气分布规律的研究认为,胡状集北部沙一段各套地层的构造形态简单,构造圈闭少,对于寻找构造油气藏来说,勘探风险比较大。而研究区有多种典型的地震异常体,如盐类透镜体、上超、断续强反射等,这些地震异常体的发现对研究区寻找隐蔽油气圈闭有重要的指导意义。
utilizing the method of sequence stratigraphy and the seismic lithologic inversion technology,This article analyses geological conditions such as stratum,construct and sediment of Sha-1 member of the north area of Huzhuangji in Dongpu depression and what the petroleum distribution rule in the region is,obtained conclusions of these,it is the greater risk of exploration to search for structural reservoir,and these seismic anomaly bodies have the important guiding sense to seek the hiding petroleum trap in the research area.
