摘　　要：复兴地区位于梁平-开江陆棚西南缘,二-三叠系沉积时期为一缓坡沉积环境,具有礁滩体规模小、有效储层厚度薄、物性横向变化快的特点。在深入分析研究区地层岩性、沉积旋回组合和测井响应特征的基础上,利用2018年针对目的层的重新处理地震资料开展地震储层预测,重点研究了飞仙关组储层特征及空间展布规律。研究认为飞仙关组鲕滩受古地貌控制,整体呈北西-南东展布,具有自南西向北东迁移并连片分布的特点,圈定了鲕滩有效储层分布的2块有利区;储层精细描述结果显示,福石2井东南高能鲕滩异常体特征明显、储层物性较好,是下一步勘探的重要目标。Located in the southwest margin of Liangping-Kaijiang continental shelf,Fuxing Area is in a gentle slope sedimentary environment during the permian-triassic sedimentary period,which is characterized by small reef beach body size,effective thin reservoir and the rapid lateral change of the physical properties.On the basis of in-depth analysis of formation lithologic,sedimentary cycle combination and logging response characteristics in the area,this paper predicts seismic reservoir by using the reprocessing seismic data of the target formation in 2018,mainly studies reservoir characteristics and spatial distribution rules of Feixianguan Formation and believes that the oolitic beach in Feixianguan Formation is controlled by paleogeomorphology,which is distributed from northwest to southeast,and has the characteristics of migration from southwest to northeast and continuous distribution,which delineates two favorable areas for the distribution of effective oolitic beach reservoirs.The fine reservoir description results show that the high energy oolitic beach anomaly body in the southeast of Fushi 2 Well has obvious reservoir physical properties and is an important target for further exploration.
