摘要
对高邮凹陷花庄油田阜三段岩石类型、粒度分析、沉积构造特征和测井相进行综合分析,从而对研究区沉积相类型及特征进行了深入研究。研究确定高邮凹陷花庄油田阜三段发育三角洲沉积体系,主要发育三角洲前缘和前三角洲2种亚相,缺失三角洲平原亚相。三角洲前缘亚相进一步划分为水下分流河道、河口砂坝、远砂坝、前缘席状砂、水下分流河道间等微相。在综合考虑研究区沉积背景及沉积特征的基础上,建立了研究区的沉积模式,为寻找剩余油提供了重要的地质依据。
The sedimentary facies and characteristics of the third member of Funing Formation in Huazhuang Oilfield in Gaoyou Sag are studied through comprehensive analyses of rock types, grain size,sedimentary structural features and logging facies.The study shows that delta sedimentary systems are developed in the third member of Funing Formation in Huazhuang oilfield in Gaoyou Sag,two main subfacies of delta front and predelta are developed with the absence of delta plain subfacies.The delta front subfacies can be further divided into sedimentary microfacies of underwater distributary channel, mouth bar, distal bar,frontal sand sheet and underwater distributary interchannel.The sedimentary mode is established on the basis of considering the depositional setting and the sedimentary characteristics.It provides important geological reference for finding remaining oil
