Abstract

Thin inter-bedded reservoirs,lithologic reservoirs and subtle reservoirs have gradually become the focus of exploration and development,which requires higher resolution processing methods and fidelity processing.In the process of improving resolution of conventional seismic data processing,the focus is mainly concentrated on the study of improving resolution methods,and there is a lack of systematic and comprehensive quantitative evaluation and analysis methods and software modules for improving resolution effect.In order to meet the urgent need of improving resolution quality monitoring,the authors carried out the study and development of evaluation methods and technical modules for improving seismic resolution effect so as to optimize the processing technology,process and parameters of improving resolution efficiently,comprehensively and reliably monitor the processing process of improving resolution,and realize the quantitative evaluation and analysis of the effect of improving resolution processing of seismic data.Quantitative evaluation method of improving resolution effect was applied to Shawan Formation thin layer reservoir in Chepaizi area.Quantitative evaluation and analysis of the effect of whole process of improving resolution processing were carried out.The capability of identifying thin layer has been greatly enhanced after improving resolution processing,and ideal results have been achieved.

Key words： seismic data resolution result evaluation software module amplitude preservation
