摘　　要：锦州25-1南潜山裂缝储层埋藏深、年代老、非均质性强,影响储层发育和分布的因素非常复杂,采用单一的常规储层预测方法难以准确预测储层的分布。基于裂缝形成的主控因素和储层特征分析,运用等效应力场模拟与叠前弹性波阻抗反演方法综合预测了锦州25-1南潜山裂缝储层分布,并得到了后钻开发井的验证,这在渤海油田尚属首次,对同类储层研究具有一定的借鉴意义。In Jinzhou25-1S buried hill,a single conventional method can not be used to accuratelly predict fractured reservoirs,because of their deep burial,old age and high heterogeneity and complex factors affecting their development and distribution.The major factors to produce fractures and the reservoir characteristics were analyzed in the buried hill.Then equivalent stress-field simulation and pre-stack elastic impedance inversion were comprehensively used to predict the distribution of fractured reservoirs there,with the results confirmed by the follow-up drilling.It is the first time to use the approach in Bohai oilfield,and this may be used for reference in other similar reservoirs.
