Abstract

Further study of the geology in the steep slope zone of Biyang depression reveals favorable reservoiring conditions and great exploration potential.In view of the large surface relief

inaccurate positioning of the major boundary faults through seismic processing

and low ascertainment degree of traps

prestack depth migration processing and subtle trap identification are carried out by using the re-acquired 3D seismic data

leading to the discovery of several oil-bearing traps with controlled geological reserves of 17.4 millions of tons in Liyuan area of southern steep slope zone.
