The southern area generally exist bare carbonate area.The physical conditions of carbonate rock strict limit the explosive efficient energy generation,transmission and reception,and leading to the bare carbonate area′s seismic data very low in signal-to-noise.In the effect of carbonate outcropped area seismic data quality factors,energy transfer problem is the first problem to solve.Through the study of carbonate rock of the excitation mechanism,in permitting of surface conditions selecting controllable source can obtain relatively high SNR data.Make full use of the successful experience that obtain a higher signal to noise ratio data in the loess plateau area by using the multi-well small explosives excitation,flexible application in carbonate outcropped area,looking for a way to suitable for carbonate outcropped area of excitation.
