Abstract:
Chuxiong basin is one of the main marine carbonate oil and gas exploration regions,it located in the southwest of the Yangtze plate,and with long and multiple geological movements.So now its surface topography is complex and up and down dramatically,and the subsurface structure and the fault underground are very complex.This area has the character that both the surface complex and the subsurface are also complex,this region is a typical low s/n ration area.With many years experiences in this region,we throught that we can got better reflection data from the simulation technology,this technology has four steps:① Establish the model of the surface elevation and underground target model;② Estimate the geological simulation profile along the survey line;③Seismic acquisition simulate according to the line simulation model;④ Correct the seismic line simulation model and the operation parameters.
