Monitoring and evaluation technology for high resolution processing of seismic data

Thin-bedded lithologic reservoirs have gradually become an important field of exploration and development. Thin-bedded sand bodies require higher requirements for improving resolution processing methods and results fidelity. In the processing of high resolution,the research mainly focuses on high resolution algorithm, and lacks systematic and comprehensive monitoring and evaluation methods. In order to meet the urgent need of improving resolution,the research of monitoring and evaluation technology for improving seismic resolution was carried out. The processing flow of improving high resolution was monitored comprehensively and reliably from nine aspects of attribute characteristics,and the quantitative evaluation and analysis of processing results was realized. Thus,the processing technology,process and parameters of improving resolution were optimized efficiently,so as to obtain the best high-resolution data. This technology has been applied in Zhuang-3 well area in the central of Junggar Basin. The whole processing of improving high resolution was evaluated and analyzed. The problems of conventional processing parameter test were solved,and the recognition ability of thin sand body was significantly enhanced after improving seismic resolution.
