Continental slope gravity flow channel is an important part of deep-water source-sink system, and it is also a critical target of international deep-water oil and gas exploration. The recent exploration of oil and gas has revealed that the distribution of gravity flow channels is complex in thrust fault zone of continental slope. While the influences of thrust faults on gravity flow channels have been studied all over the world, few researches have been carried out in terms of microtopography styles formed under the comprehensive action of thrust-transfer structures and their control on gravity flow channels. Taking a deep-water study area in West Africa continental slope as an example, this paper applies core, logging and seismic data comprehensively to clarify the types and genesis of thrust-transfer microtopography and the control of microtopography on distribution of gravity flow channels. High-resolution 3D seismic data was employed to investigate the thrust faults and distribution of gravity flow channel. Thrust fault traces were tracked in seismic profiles based on reflection terminations and offsets. Two stratigraphic units (S1, S2) were interpreted according to the characteristics of seismic facies and the geometric relationship between strata and stratigraphic surface. Both S1 and S2 were interpreted to represent the growth strata that was active synchronously with the thrust faults. Application of RMS amplitude attribute within time windows was done for clearer images to envisage the location and form of gravity flow channels. Paleogeomorphology maps were made from stratigraphic thickness and indicated the distribution of gravity flow channels in the study area. Results and conclusions were as follows: In Miocene, topography of the study area was dominated by arcuate thrust faults and fault-related folds oriented perpendicular to the continental slope, and the thrust faults were connected by transfer structures. Thrust faults, which were formed as a result of the gravity sliding, were developed toward the deep water. Two different thrust fault systems in study area were developed along two detachment surfaces at different depths in the overpressure mudstone, resulting in different thrust displacements, which was the main reason for the difference in structural style and activity intensity between the two thrust fault systems. Displacements of two thrust fault systems and difference of the displacement along the strike of a single thrust fault led to a variety of transfer structures. Controlled by thrust-transfer structures, five different microtopography styles were summarized from the perspective of genesis: triangular faulted anticline, tear fault-diapir anticline, reverse fault connection valley, tear fault slope and strike trough. Under the influence of thrust-transfer microtopography, contemporaneous gravity flow channels showed three plane distribution styles: diversion, crossing and confinement. Triangular faulted anticline and tear-diapir anticline deflected gravity flow channels that were developed along continental slope. Reverse fault connection valley and the edge of tear fault slope enabled gravity flow channels to cross the faults. Strike trough confined gravity flow channels. This study could provide a new analytical approach for seismic interpretation of gravity flow channel reservoir.
