The Carboniferous of Zhongguai Uplift develops igneous rock.High velocity igneous rocks have a shielding effect on underlying formations,which leads to poor imaging quality and is not conducive to fine exploration.The distribution rule of oil and gas in Carboniferous reservoirs is complex,and each trap has different oil-water interfaces.The distribution of oil and gas is controlled by fault,and the fine description of faults is affected by the quality of seismic data,and the minor fault is very difficult to identify.The conventional high resolution processing techniques always compensates the high frequency components while the signal-to-noise ratio decreases;in consequence,it makes the structure interpretation difficult,especially for the small fault.To satisfy the exploration demand in following stage,a high resolution technique based on Generalized S-transform is introduced in this paper.The proposed method is characterized by high fidelity and preserved-amplitude;it can compensate the high frequency contents on the basis of high signal-to-noise ratio.This method makes the seismic reflection continuous,and has the potential in the detailed seismic interpretation and seeking the structural trap.
