Abstract: The western Fukang fault zone underwent multi?stage tectonic movements and the complex faulting systems were developed, which caused the fault identification and the structural modeling were difficult. Based on the theory of fault?related folding, the 3D structural model has been developed in three steps: 1) complex seismic profiles are calibrated with stratum and stratigraphic dip by means of geologic, well logging and seismic data; 2) the iso?dip domain division and axial plane analysis based on the calibrated seismic profiles as well as geometrical analysis of the framework in the whole area are conducted, so as to develop the structural model of the target area; 3) the 2D and 3D integrated seismic interpretation data are used to develop 3D model for the whole area using Earth Vision software. The studied results show that there are two sets of regional fault systems laterally distributed in EW or near EW and two sets of structural zones in vertical. And the over thrust structures and lithologic traps between Fukang fault and Ganhezi fault are favorable zones for oil and gas exploration in this area
