摘　　要：针对滩坝因厚度较薄、地震响应不明显、横向连续性差而长期以来缺乏有效预测方法的状况，在勘探实践的基础上，提出了一套以地质规律为指导、综合运用地震储层预测技术预测滩坝的方法，即古地貌分析预测滩坝发育区带、层序地层学研究确定重点层位、地震属性分析固定滩坝发育范围以及储层特征重构反演等技术精细刻画储层。该方法实际应用效果良好，能够对滩坝储层进行有效识别和精细刻画。The exploration of beach bar is restricted for lack of reservoir prediction technique aiming at the single layer with small thickness, indistinct seismic response and poor lateral continuity. Base on the practice of exploration, an integrated series of seism-geology prediction techniques for beach bar reservoirs, guided by the geologic laws, is proposed in this paper. That is, using palaeogeomorphology analysis to locate the development region of beach bar, using sequence stratigraphy research to determine the promising stratigraphic position, and using seismic attribute analysis to block out prospective area, as well as using reservoir characteristic reconstruction and inversion technology to describe the reservoirs accurately. This reservoir prediction technique has been proved in field practice with good effect, which can predict and identify beach bar reservoirs effectively.
