渤海湾渤南洼陷深层湖相滩坝储集层沉积微相预测
Seismic facies prediction of lacustrine beach and bar reservoirs in the deep zone of the Bonan Subsag,Bohai Bay Basin
摘要
Abstract
The lacustrine carbonates are developed in the Paleogene Sha 4 Member of the Bonan Subsag in the Zhanhua Sag of the Bohai Bay Basin. This type of reservoirs is characterized by deep-burial, thin bed, thin alternated bed deposition, complicated rock types, and a dramatic lateral change of lithofacies, so the main problem of its exploration is the identification of effective reservoirs. On the basis of analyzing rock facies and geophysical features, this paper develops a new technique for the prediction of complicated lithofacies based on sedimentary parameters. It begins from the normal seismic attributes analysis such as amplitude and frequency types, extracts the 3D seismic attributes, counts the sedimentary parameters such as the percent of the limestone, and sets up the relationship of the sedimentary parameters from wells and the seismic attributes along wells, and then computes the lateral features of many sedimentary parameters.At last, the cluster analysis is done to predict the sedimentary facies. This technology gets a preferable result in the Sha 4 Member of the Bonan subsag, and it can provide some reference for other types of depositional system.关键词
