摘要：

通过对民丰洼陷的油气成藏特点、油气富集规律及主控因素进行研究,表明该区处在凹陷东北边缘的特殊位置,成藏条件优越.古近系岩性油藏主要包括砂岩透镜体油藏、砂体上倾尖灭油藏和砂体被断层切穿的岩性油藏3种类型.三角洲前缘砂体、滑塌浊积岩砂体的性质和分布,砂体分布范围内有利的构造位置和有利的沉积储集相带成为控制岩性油藏形成的主要因素.油气勘探方向应围绕不同时期、不同部位两种成因的储集砂体展开.

Abstract: A study on the characteristics,patterns,and controlling factors of hydrocarbon pooling in Minfeng sag reveals that the sag occupies an advantageous place for oil pooling in the northeastern margin of Dongying depression.The Paleogene lithologic oil reservoirs are mainly sand lens reservoirs,updip pinchout sandbody,and sandbody reservoirs cut through by faults.Major controlling factors of the lithologic oil reservoirs include the properties and distribution of delta front sandbodies and fluxoturbidite sandbodies,the favorable structural location within the distributions of sandbodies,and the prospective sedimentary reservoir facies belts.It is suggested that the exploration be focused on the delta front and fluxoturbidite reservoir sandbodies of different ages formed in difference structural positions.

Key words: lithologic oil reservoir, control factors, delta,fluxoturbidite, Minfeng sag, Jiyang depression
