Abstract
Conventional towed cable seismic acquisition operational mode causes unilateral sufficient illumination and blur image at buried hill or high-steep structure area due to its single-side shooting and single-side receiving with single azimuth.We put forward acquisition design of fore and after source double-way simultaneous shooting through analyzing limitation of conventional towed cable to improve illumination of both sides for the high-steep structure.In China,fore and after source double-way simultaneous shooting operation is firstly carried out with optimal selection the operation mode,in which the assistant seismic vessel is shooting by chasing the tail-buoy by comparing the different implementations.The application in JZ block proves that:compared to conventional towed cable seismic acquisition,the new method can improve the imaging of buried hill and fully promote the operational potentiality in buried hill and high-steep structure area.The technical process is feasible and the operation mode is reasonable,which is of significant reference for potentiality exploitation of towed cable seismic operation.关键词
