LITHOLOGIC OIL POOL EXPLORATION METHOD——A CASE STUDY OF THE LIAOHE DEPRESSION IN THE BOHAI BAY BASIN

MQZ region is situated in the western sag of the Liaohe Depression in the Bohai Bay Basin.The ramp zone controlled by slope break is favorable for underwater fans generation.Since they are near source rock and have good reservoir beds and channels,the low-system-type fans can form lithologic oil pools.By exploring lithologic traps in MQZ area,it is concluded in this paper the 3 ways to explore lithologic traps.High resolution seismic data are the base of lithologic trap exploration,sequences stratigraphy is the theory, and seismic prediction technology is the method.
