摘　　要：鄂尔多斯盆地苏里格气田西区苏54区块主力气层上古生界下二叠统下石盒子组盒8段属于砂岩岩性气藏,储层致密,非均值性强,有效储层薄且相对孤立分散,含气富集区不明朗,开发难度较大。针对该区块开发难点问题,利用AVO烃类检测及叠前参数反演技术对主要目的层段进行了储层厚度、有效储层厚度及含气性预测,在储层综合评价的基础上优选了含气富集区。以地震储层预测成果为主要依据部署实施开发井54口,Ⅰ+Ⅱ类井比例较勘探阶段大幅度提高,开发效果良好。该区块的开发实践表明,所运用的地震储层预测技术行之有效,值得同类气藏开发借鉴。The eighth member of Upper Paleozoic Lower Permian Xiashihezi formation in Su-54 block is the main gas reservoir of the block, and it belongs to sandstone lithologic gas reservoir. The reservoir is tight and severely heterogeneous. Effective reservoirs are thin and their distribution is dispersed. The gas-rich regions in the studied area are not understood and there^bre there are difficulties in the development of the reservoir. For this reason, the reservoir thickness, the effective reservoir thickness and the gas-bearing feature of the main target segments are predicted using AVO hydrocarbons detection and pre-stack parameter inversion, and the gasrich regions are optimized based on the comprehensive evaluation of the reservoir. 54 development wells are arranged according to the seismic reservoir prediction results. The proportion of Ⅰ ＋ Ⅱ type wells in development phase is higher than in exploration phase, and a good development result is achieved. The development practiees in Su-54 block show that the use of seismic reservoir prediction technique is very effective and is worth drawing in the development of similar gas reservoirs.
