摘　　要：潜江凹陷潜江组沉积时期发育三角洲-盐湖体系潜34、潜40等油组在洼陷带发现多个岩性油藏,具备广阔的勘探潜力。分析了潜江凹陷蚌湖向斜地区的沉积背景和储层特性,结合地震反射特征、属性分析、正演模拟和地震反演描述总结了储层分布规律。利用测井资料、地震资料进行储层精细标定和识别追踪,预测有利砂体展布区,半干旱期成藏主控因素为储层和油源距离,预测结果与钻井和地质规律相符。The delta-salt lake system was developed in the sedimentary period of Qianjiang Formation in Qianjiang sag,Among them,many lithologic reservoirs were found in Eq34、Eq 40 and other oil formations in the hollow zone,which has broad exploration potential.This paper analyzes the sedimentary background and reservoir characteristics of Benghu Syncline in Qianjiang sag,and summarizes the reservoir distribution combined with seismic reflection characteristics、attribute analysis、forward modeling and inversion description.Using logging data and seismic data for fine labeling of reservoir,identification and tracking,to predict the favorable sand body distribution area,it is considered that the main controlling factors of reservoir formation in semi-arid period are reservoir and oil source distance,and the prediction results are consistent with drilling and geological laws.
