摘　　要：板桥斜坡是歧口凹陷主要勘探区块之一,该区经过50余年的勘探开发已经进入高勘探阶段,如何持续获得高效优质储量,是油田持续稳定发展必须面对的现实问题。鉴于当前面临的技术难题和增储上产的需求,针对斜坡区构造成因、沉积储层、油藏特征等方面开展了综合研究。结果表明:板桥地区沙河街组扇三角洲前缘水下分支河道、河口坝和滨浅湖砂坝主体为最有利的沉积相带,在滨Ⅰ中、滨Ⅰ下等有重大勘探突破,证明该区仍有很大的勘探潜力。Banqiao slope is one of the main exploration blocks in the Qikou sag.After the exploration and development more than 50 years,this area has entered the stage of high exploration.How to obtain efficient and high-quality reserves continuously is a practical problem that must be faced with for the sustained and stable development of the oilfield.In view of the current technical difficulties as well as the demand of increasing reserves and production,a comprehensive study has been carried out on the tectonic origin,sedimentary reservoir and reservoir characteristics of the slope area.Results show that underwater distributary channel and mouth bar of fan delta front,sand bar body of shore-shallow lake is the most favorable sedimentary facies belt in the Shahejie Formation,Banqiao area.The important exploration breakthrough have been achieved in Middle and Lower BinⅠ,which proves that the Banqiao area still has great exploration potential.
