基于层控蚁群层位自动追踪的Wheeler转换方法及其应用
Wheeler conversion method based on layer-controlled horizon automatic tracking with ant-colony algorithm and its application
摘要
Abstract
Continuity of the same phase axis is enhanced with pretreatment of seismic data.Then,the support vector machine technology is introduced to classify the points on the seismic profile.An improved ant-colony algorithm for seismic horizon correlation and automatic tracking algorithm is proposed,in which the information of seismic amplitude,instantaneous phase,dip angle,and pheromone concentration is used as the evaluation function of ant-colony horizon tracking.On this basis,contrast and tracking results of sedimentary cycle rhythm in time-depth domain are transformed to Wheeler domain which realizes synchronous interpretation of time domain and Wheeler domain.Thus,the spatial relationship of sedimentary assemblages is revealed effectively with highlight loss and overlay mode to make it possible to extract time slices in the age-strata domain,which have a deeper understanding with the time of deposition,erosion and deposition.The validity of the method is verified by the application of the actual seismic data.关键词
