摘　　要：鄂尔多斯盆地苏里格气田的气藏属于大面积分布的低压、低含气饱和度气藏,主要储集层为上古生界河流相叠合砂体,以高分辨率二维地震为基础的储集层预测在该气田的发现中发挥了关键作用。在分析近年地震预测效果的基础上,从野外采集、原始资料品质、处理及解释等方面分析影响预测精度的主要因素,根据寻找富集高产区的开发生产需求,建议加强基于全三维数据体的叠前多属性分析、以测井资料和地层等时格架约束储集层反演、开展弹性波反演技术研究,并建议在积极开展地震资料品质攻关的基础上,进行适量的三维VSP及多波地震的试验攻关。Sulige Gas Field is a large but low pressure and low saturation gas field located in the Ordos Basin. The main reservoirs are of Late Paleozoic amalgamated fluvial channel sands. High-resolution 2-D seismic played a critical role in reservoir prediction and the discovery of gas fields. Data acquisition, quality, processing and interpretation in recent years are reanalyzed to improve the predictability of future work. To meet the ever increasing gas field development demand, it is suggested here to apply 3-D pre-stack seismic attributes analysis, well-logging, strata time-frame constraint, reservoir inversion and elastic wave inversion technology, 3-D VSP and 3-C seismic techniques in future work.
