下刚果盆地下白垩统Albian阶碳酸盐台地地震沉积学
Study on seismic sedimentology of the Lower Cretaceous Albian Stage carbonate platform in the Lower Congo Basin
摘要
Abstract
Data of drilling cores,logging and three dimensional seismic data are used to discuss the characteristics of seismic geology,spatial distribution of favorable reservoir and evolution regularity of the carbonate sedimentary system in Lower Cretaceous Albian Stage in Lower Congo Basin,so as to provide geological evidence for the prediction and selection of exploration targets.It shows that the Block A and its adjacent area in Albian Stage,Lower Congo Basin can be classified into 3 kinds of hybrid facies,6 kinds of subfacies and even more kinds of microfacies.On the basis of establishment of sedimentary model of hybrid facies,the growth period,direction and paleotopography height of beach body are determined,the development and evolution rules of the beach body in the key section of Block A and adjacent area are clarified,the sedimentary evolution history of SQ2 and SQ3 sequence is finely reconstructed and the evolution characteristics of each sequence and the distribution rules of favorable reservoir facies belt are recognized.Accordingly,a research system of comprehensive multi scale combination is proposed and the 3D dynamic sedimentary evolution model of Albian Stage in the Lower Congo Basin is established.It reveals that the platform gully controls the belt,platform margin controls the beach and beach controls reservoir is the reservoir development mechanism in the area.关键词
