摘　　要：中江气田JS气藏河道具有宽度窄、厚度薄、相互叠置复杂隐弊致密的特征。针对薄互层砂体地震分辨难、钻井跟踪难背景下,开展了高分辨谱反演拓频和波形特征指示反演技术,能显著地拓宽地震频带提高分辨率,从而识别薄储层和理清多期次叠置河道砂体,为钻井跟踪提供可靠的依据。将该技术应用于中江气田JS气藏的开发评价工作中,有力地助推高效评价建产。JS gas reservoir in Zhongjiang gas field is a tight channel characterized by narrow width,thin sand body,complex sedimentary law,multi-cycle,multi-flow,and common staggered vertical phenomenon.So conventional seismic data are difficult to accurately describe the shape and stage of the channel.With the deepening of exploration and development,stratigraphic qualitative prediction has been difficult to meet the needs of evaluation and development,fine determination of channel sand body.Therefore,the spectral inversion extension frequency processing technology can be used to widen the seismic data spectrum,which can effectively identify the Marine reservoir and describe the superposed channel sand body.By using the high-resolution shard waveform characteristic indication inversion technology,the channel sand can be predicted with high precision and fixed distance,and the same basis can be provided for drilling tracking.The application of the high-score seismic technique in the development and evaluation of the gas reservoir in Zhongjiang gas field will have effectively boosted the efficient evaluation and production of the gas reservoir.
