摘要
Based on the geologic interpretations of the seismic reflection data, the authors investigated the growth rate and the evolution of the master faults forming basin boundaries by applying the method of analyzing the relationship of displacement-length along strike of normal faults and the approaches for analyzing growth rate along dip direction. It is revealed that the faults formed mainly in the Shahezi Period. Only weak and local faulting activity occurred around some linking areas after the Yingcheng Period. The oil and gas fields are mainly located in the areas where secondary tectonic element developed. This finding bears important implications for the further oil and gas exploration in Xujiaweizi Area.
