摘　　要：渤深6块潜山储层位于沾化拗陷渤南凹陷北部，埋藏深度4100～4900m，储层发育及成藏规律复杂。为了高效开发渤深6块，必须引进和优化潜山油藏描述技术，然后根据自身特点选择优化并创新使用。采用地震资料目标处理、叠前深度偏移、高精度三维地震采集处理解释等基础资料处理技术；用多井地震合成记录综合标定、变速成图等技术准确描述潜山形态。多井采用了斯伦贝谢成相、核磁共振测井、多尺度边缘检测平面预测等先进技术，最后根据录井、测井等多项信息进行综合判识并量化。应用结果表明，渤深6块15口新井全部钻遇设计油层，且均自喷生产，投产平均产油能力84t／d，产气5×10^4m^3／d，油藏开发效果好。It is difficult to discover the subtle deposit in area with high exploration mature. This paper illustrates great discovery of subtle deposit in turbidity channel sand in the Bonan Depression caused by two aspects. The first one is the prosperous exploring potent revealed by the analysis of the feature of oil test of some wild wells. The second one is the new recognition in sedimentary pattern in the area where the pattern of sheet sand sediment pattern is replaced by the turbidity channel sand resulted from the geological research with advanced techniques, including integration treatment of seismic data, mapping with variable velocity, reservoir analyzing according to principle of sequence strategy, reservoir prediction under control of sedimentary face, and reverse of seismic data with boundary of well log data. Application indicates that the reservoir is drilled by 15 wells with 84 t/d oil and 5 × 10^3 m^3/d gas production.
