Petroleum Geophysical Prospecting, 2 0 0, 38 (3): 2 97 ~ 30 2 Due to the lack of systematic analysis of the key factors, the exploration of Mesozoic in the Kongxi fault zone has been at a standstill. Based on the macrostructural background analysis, the paper first divides the scope of the Kongxi fault zone, the inner trap and the main faults, and elaborates the forming elements of the Mesozoic in the fault zone. Secondly, The topography, the source rock distribution, the relative position between the oil reservoir and the reservoir, the main fault occurrence and the activity intensity have the conditions of lateral migration, and the crude oil analysis also confirmed that the fault zone In the end, according to this migration method, the search for favorable targets is carried out. It is found that there are great exploration potentials at both ends of the Kongxi fault zone.
