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.

Key words: hydrocarbon accumulation condition, exploration practice, 3D seismic survey, subtle trap, southern steep slope zone, Biyang Depression
