Abstract：Stratigraphic/lithologic traps are playing an increasingly important role as hydrocarbon reserves and productions from them are growing. Focusing on three dominating types of lithological traps in South Turgay Basin, i.e. channel sand body, up dip wedge-out and buried hills, this paper introduces a two-step work flow for identification and characterization of lithological traps. The first step is to setup the sequence stratigraphic framework and to qualitatively describe the type, characteristics and distribution of lithological traps. The second step is to quantitatively characterize the shape, thickness and physical properties of the traps by some seismic reservoir prediction approaches. This work flow has been proved to be effective in the exploration practice in South Turgay Basin for above-mentioned three types of lithological traps.
