通过石油地质综合研究,基本明确了金湖凹陷及腰滩地区的石油地质特征:主要沉积盖层由古近系泰州组、阜宁组、戴南组、三垛组及新近系盐城组组成,其勘探主要目的层为古近系地层;在凹陷的发育演化过程中,自下而上主要发育了古近系泰州组、阜宁组二段、四段和戴南组等多套砂岩储集层,以三角洲前缘相砂体为主;构造是控制油气藏富集的主要控制因素,凹陷已分别在上述各储集层段发现油层并获得工业油气流,对于腰滩地区,目前发现的油藏主要分布在阜一、阜二、阜三及戴一段砂岩储层中,具有良好的油气勘探前景。
Through the comprehensive study of petroleum geology, the petroleum geology characteristics of Jinhu depression and Yaotan area are basically clarified. The main sedimentary cover consists of Paleogene Taizhou Formation, Funing Formation, Dainan Formation, Sanduo Formation and Neogene Yancheng Formation. During the development and evolution of the sag, there are mainly sandstone reservoirs in the Lower Paleogene Taizhou Formation, the second member of Funing Formation, the fourth member and the Dainan Formation, etc. Layer is dominated by the delta front facies sand body. The structure is the main controlling factor for controlling the accumulation of oil and gas reservoirs. The sags have been found in the reservoirs above each other to obtain industrial oil and gas flow. For the lumbar region, The reservoirs are mainly distributed in sandstone reservoirs of Fu 1, Fu 2, Fu 3 and Dai Wei, and have good prospect of oil and gas exploration.
