Abstract：Laoyemiao oilfield has complex continental deposit characteristics such as multi-provenance,multiple depositional systems,current energy variation,frequent transgression and regression,fast facies change,multi-faults,small displacements,thin beds and horizontally fast changes.These cause a real challenge for seismic exploration in the area.To solve the geological problems,this paper introduces a method for seismic data resolution improvement with wavelet analysis in the condition of keeping high signal-to-noise ratio data,and proposes its implementation procedure.Applications of this method to synthetical data and real field data prove its validity and effectiveness for seismic data resolution improvement of thin interbeds.Its results will be helpful to thin interbed distribution delineation and reservoir prediction.
