Abstract:

It is known that the conventional common midpoint binning method can not be used in converted wave processing because of the asymmetry during the converted wave propagation. Therefore, the research on converted wave common conversion point （CCP） binning method is very important. At present, asymptotic method and target-oriented method are twomain kinds of common conversion point binningmethods. Through the comparison and analysis of these two kinds ofmethods, this paper carried out common conversion point binning of converted wave data in the actual field, and compared the stack sections obtained by the two kinds ofmethods. The result shows that the target-oriented method can calculate the conversion point position of the target time or layer flexibly, which is better than asymptotic method.

Key words: micro suspension emulsion, high water content, heterogeneity, permeability ratio, core displacement
