广利及周缘地区构造位置上位于济阳坳陷断陷湖盆东营凹陷的东部,是陡坡带基岩内侧向凹陷区的转折部位。本区的两个洼陷中心有着不错的油源条件,可以为储集层提供充足的油气来源。从广利及周缘地区的油气成藏特点来看,油气成藏主要受到以下三点因素控制:(1)有利储层的发育与分布;(2)油气运移与遮挡方式;(3)构造与圈闭形态的控制作用。广利及周缘地区发现的油藏类型可分为构造、岩性和构造—岩性或岩性—构造三大类。
Located in the eastern part of the Dongying Sag of the fault depression lake basin in the Jiyang depression, Guangli and its peripheral tectonic positions are the turning points of the lateral sag zone in the steep slope bedrock. The two sags centers in this area have good oil source conditions that provide adequate source of oil and gas for the reservoir. From the characteristics of hydrocarbon accumulation in Guangli and its peripheral areas, hydrocarbon accumulation is mainly controlled by three factors: (1) the development and distribution of favorable reservoirs; (2) the migration and occlusion of hydrocarbons; and (3) the structure And trap shape control role. The types of reservoirs discovered in Kwang Lee and its peripheral areas can be divided into three categories: tectonics, lithology and tectono-lithology or lithology-tectonics.
