通过对舍女寺油田n90-10断块地质综合分析结合地震相分析技术对舍女寺油田的沉积相进行了划分,根据取芯井资料,结合岩相、电性特征分析、古生物分析、和属性预测技术(均方根振幅属性)的基础上,确定了孔二段的沉积相的类型。目标区为三角洲前缘主体沉积,储层较发育。同时利用地震资料,在构造精细解释的基础上,通过地震相多属性小时窗的提取,分析沉积相平面展布及物源方向。分析认为研究区的孔二段为三角洲前缘亚相沉积,沉积微相主要发育水下分流河道、水下分流河道间湾、前缘席状砂。
Based on the comprehensive analysis of the n90-10 fault block in Shensi Oilfield and the analysis of seismic facies analysis technology, the sedimentary facies of Shensi Oilfield is divided. According to the data of coring wells, combining lithofacies, electrical characteristics analysis, paleontological analysis and Based on the property prediction technique (root mean square amplitude property), the type of sedimentary facies in the second member of Konggong is determined. The target area is the deposition of the delta front and the reservoir is well developed. Based on the detailed interpretation of the seismic data and the extraction of multi-attribute small time windows, the sedimentary facies plane distribution and source direction are analyzed. The analysis shows that the second member of Konggou Formation in the study area is the sedimentary facies of the delta front. The sedimentary microfacies mainly develop underwater distributary channel, underwater distributary channel bay and front edge sands sand.
