摘　　要：渤海海域新近系河流相油田投产后储量变化研究表明,在油田开发初期,开发井钻遇新的含油砂体是储量增长的主要原因,占油田总储量的30%,为合理把握油田储量规模、科学部署开发设施及确保开发效果,在油田开发初期阶段研究探井未钻遇的潜力砂体意义重大。依据渤海新近系成藏理论和十多个已开发河流相油田钻井证实含油砂体的成功因素,论证潜力砂体含油可能性高的3种类型,依据相控储层描述技术开展潜力砂体的定量描述。该技术成功应用于BZ油田滚动扩边块3井区,钻前预测的潜力含油砂体储量近8×106m3。在近几年油田开发初期阶段预测和论证的潜力砂体中,开发井钻后67%的潜力砂体储量得到落实,达到了合理部署河流相油田开发设施的目的,提高了开发效果。New oil - bearing sand bodies drilled on the stage of oilfield construction is important portion of fluvial oilfield reserves. The development facilities have a good effect for reasonable controlling the fluvial oilfield reserves; therefore studying potential oil - bearing sand body is very important. Based on analysis of Bohai development fluvi- al reservoir, by using sand body description and hydrocarbon pooling factors of drilled oil -bearing sand body, three types of potential oil - bearing sand bodies were demonstrated. Based on the study of potential oil - hearing sand body types, the sand body＇ s distribution were done by using sand body description technology. The technolo- gy are successfully applied in 3 block of BZ oilfield, the predicted reserves were confirmed after drilling, nearly 800 x 106m3. In recent years, 67% reserves of the potential sand bodies which predicted in early development were confirmed after development wells drilled, this technology has been implemented to achieve the purpose of improved development results.
