摘　　要：利用对盐间非砂岩储层的物性统计分析、薄互层的模型正演、地震资料的波阻抗反演和构造曲率分析等方法对王场地区的裂缝-孔隙储层的物理特性、裂缝发育特点和分布规律、以及预测中的地震地质资料使用条件等方面进行研究,总结了适合该区的盐间非砂岩储层的预测方法:用模型正演分析地震、地质资料对储层预测方法的有效性,编制目的层段波阻抗异常图预测裂缝-孔隙储层发育有利区,通过构造曲率法进一步圈定有效区。该方法为整个潜江凹陷的盐间非砂岩储层的研究和预测提供了好的借鉴。The physical properties of fracture-pore reservoirs, the characteristics and distributional rules of fracture growth and as well conditions for application of geologic and seismic data in the prediction in Wangchang Area are studied by using physical statistical analysis of non-sandstone reservoirs within the salt-layer, forwarding thin interbed, wave impedance inverse of seismic data and structural curvature analysis. Methods for predicting the sandstone reservoirs with salt layer suitable for the area are summarized; which include the effectiveness of seismic and geologic data to the reservoir predicting methods is analyzed by using model forwarding. Abnormal chart of target zone wave impedance is made to predict the growth of beneficial area of fracture-pore reservoirs, and effective area is further determined by structural curvature method. Good reference is provided for studying and predicting inter-salt non-sandstone reservoirs for the whole Qianjiang Depression.
