摘要
Using three-dimensional seismic and drilling/logging data, by researching Shinan fault of Bozhong Depression and distribution of depositional system, this paper discusses the control of combination patterns of faults over the sandbody. The results show that the Shinan fault can be divided into six parts according to different strikes,and the combination patterns of the intersection of adjacent sections are “concave” and “convex”. At the “concave”, it is easy to form the progradation of main provenance and gather sandbody near the basin, and in uplifted area, paleovalleys developing along faults are the main pathways of clastic progradation. While at the “convex” it is hard to build up large-scale distribution of sandbody.
