摘要
Abstract
Rich oil and gas resources in west Kunlun piedmont belt,southwest of Tarim basin,is one of the main seismic exploration area of Tarim oilfield company in recent years.However,due to geological conditions underground complex surface effects and poor seismic imaging area in the west Kunlun piedmont,it is difficult to meet the needs of geological exploration for a long time.Among the many factors affecting the seismic data imaging,the western Kunlun piedmont ubiquitous thick loess and dramatic ups and downs so that the area of surface statics problem is particularly prominent for late denoising,migration velocity analysis and imaging processing adversely affected area is one of the main causes of poor seismic imaging.Based on the wave equation forward modeling of seismic exploration practice combined analysis of the main reasons the west kunlun piedmont zone statics problems,which put forward a comprehensive static correction method based tomostatics,reach fine portray thick the purpose of the near-surface layer of loess complex structure.关键词
