根据岩心相、测井相、地震相,结合对背景资料的分析,认为渤海绥中36-1油田由三角洲、浊积扇、浅湖-半深湖3种沉积体系构成,合理的生、储、盖组合关系为油气聚集创造了条件。由于差异压实作用,造成潜山斜坡部位坡降加大,在洪水、地震等条件的诱发作用下,三角洲前缘沉积物垮塌形成了多期次的滑塌浊积岩。不同沉积微相沉积砂体由于砂体厚度、分布面积、储集物性、分布位置等不同,其储量丰度不同。其中,水下分流河道砂体储量丰度最高,其他依次为河口坝、浊积扇、前缘席状砂和远砂坝。
According to the core facies, logging facies and seismic facies, combined with the background data, it is concluded that the Bohai Sea Suizhong 36-1 oilfield is composed of three sedimentary systems of delta, turbidite fan and shallow lake - semi-deep lake. , Cover the combination of relations to create the conditions for the accumulation of hydrocarbons. As a result of differential compaction, the slope gradient of buried hill slopes increases. Under the conditions of floods and earthquakes, the delta front sediments collapsed to form multi-stage slump turbidite rocks. Different sedimentary microfacies sedimentary sand body due to sand body thickness, distribution area, reservoir properties, distribution of different locations, the reserves of different abundance. Among them, the distributary channel sand bodies have the highest reserves abundance, followed by the estuarine dam, the turbidite fan, the leading edge sands sand and the far sand dam.
