基于地震正演与井震结合的低序级断层描述技术及应用
Technology of Fine Characterization of Lower-class Fault Based on Seismic Forward Modeling and Well-seismic Combination
摘要
Abstract
The development practice of complex fault block reservoir shows that,the lower-class fault controls the distribution of remaining oil obviously,therefore,the fine description of the low-class faults is a key to the research of different types of fault block reservoir development technology.Meanwhile,the development of fault block reservoir is facing more and more complicated geological conditions,that is,the faults,erosion,overlap and syndeposition and other geological phenomena often coexist,which have caused complex stratigraphic contact relationship and fracture system.Aiming at solving this problem,a technology of fine characterization of the lower-class fault and its combination has been formed based on seismic forward modeling and well-seismic combination,such as reconstruction of the stratum contrast pattern by well-seismic combination to guide the accurate fault ridge identification,establishment of lower-class fault seismic identification by the combination of multiwell integrated calibration and seismic forward modeling,well-seismic multi-attribute analysis,and well-control multi-horizon tracking for the fine description of fault edge.Then,a new complex fracture system has been rebuilt in Shahejie Formation of region 2 & 6,Gudong Oilfield,based on this method,which has screened out the confusing relationship between oil and water,and achieved high development performance.关键词
