Abstract：Authors detail both experience of high-resolution seismic exploration in Luoduxi mountainous region in Sichuan basin and some measures for improving data quality. The measures such as high fold, high sampling rate, high-frequency geophone, small group interval, short array length, small offset, big charge and two isodepth planes, are taken in field data acquisition. Indoor data processing involves some special methods, including detailed dynamic and static corrections, frequency-divided processing, powerful noise elimination, dual-directional deconvolution, poststack processing and so on. In data interpretation, some effective ways are used, which are horizon determination, horizon correlation, quantitative fault interpretation, Seislog section interpretation, trace integration, etc. The application of these techniques widens hydrocarbon exploration in mid Sichuan basin.
