Abstract：Oil/gas resource is rich in piedmont of com-plex mountains that is one of major exploration fields in the west of China.There are double complex-ities in piedmont of western mountains that charac-terized by both complex and variable surface condi-tions and strong underground feature of overthrust structure,increasing the difficulty in seismic data acquisition,processing and interpretation.The dif-ficulties are focused on two aspects:lower S/N ra-tio of seismic data ratio and poorer structural preci-sion that become a technical bottleneck of develop-ing western seismic exploration.After near decade's technical tackling key problems,a set of experiences of complex mountainous seismic explo-ration has been formed,some complex structures have been successfully captured and Kela-2 gas field and Dila-2 gas field in the piedmont of Kuche foreland basin have been found.But,this success is by no means that the other problems in western mountainous exploration are readily solved.Since the seismic-geologic conditions in western complex mountains of China are complex and variable,it has to continuously develop new techniques and new e-quipments aimed at concrete existed problems,which can meet the needs of western oil/gas explo-ration.
