地震相精细刻画建南气田飞三气藏鲕滩体

Elaborating on Er Beach Body of Fei Ⅲ Gas Reservoir in Jiannan Gas Field through Seismic Facies

建南气田飞三气藏为建南气田最为重要的产能建设层,目前已进入开发中后期,气田现有老井产量即将进入递减期,产量主要集中在少数单井上,稳产风险大,为保持产量稳定,寻找储层发育有利区部署高效调整开发井势在必行。在前期沉积、储层的认识基础上,通过对单井储层、产能、地震响应特征的对比分析,运用地震相分析法对飞三气藏鲕滩体进行了精细刻画,为下一步开发部署提供了依据。

As the most important output contributor in Jiannan gas field, the third member of Fei gas reservoir has entered the late development period. Considering that the existent wells are about to decline in output and the burden falls on a handful of single wells which poses great risks to stable produetion, it＇s imperative to locate areas conducive to reservoir development and employ and adjust development wells. This paper analyzed the reservoirs features, capacity and seismic response characteristics of single wells based on the knowledge about the deposits and reservoirs during early development period. Seismic facies analysis offered a good perspective to elaborate on the features of Er Beach Bodies in the third member of Fei gas reservoir, thus offering guidance for future development planning.
