Abstract：With its many obvious advantages in lithology and fracture exploration,3C seismic exploration is favored in practical application,so more and more 3C exploration are being used.The data processing for converted wave data is more complex than the routine data,especially in the complex areas.The main problems include static correction,low signal to noise ratio,difficulties for amplitude compensation and imaging,and difficult to realize correct imaging for the converted wave by CCP method.Therefore,by using the matching static correction method to solve the static correction problem and the targeted means to suppress various noises,through the amplitude compensation and pre-stack deconvolution processing,a set of converted wave iteration processing flowchart,including static correction,pre-stack denoise,migration velocity analysis and pre-stack migration imaging,was developed.The field date processing result showed that the better quality 3D converted wave data volume was acquired by applying the flowchart,laid the foundation for converted wave data integrated interpretation and raising oil gas identification accuracy.
