摘　　要：江汉盆地潜江凹陷周返-张港斜坡带在潜江组沉积时期是岩性圈闭发育的有利区,该区岩性组合复杂,岩性圈闭识别具有较强的多解性。从实际钻井出发,结合该区沉积规律,重新刻画岩性岩相平面展布,明确储层发育的有利地质相带;开展不同岩性组合的地震响应特征分析,明确有利储层发育的波形特征及有利地震相带,地震地质结合,针对有利区优选敏感属性,开展储层预测研究,在该区发现和落实一批有潜力的岩性圈闭目标,有效指导该区岩性油藏勘探。During the sedimentary period of the Qianjiang Formation in the Zhoufan-Zhanggang slope belt of the Qianjiang Sag in the Jianghan Basin,lithologic traps developed favorably.Due to the complex lithologic assembly in this area,the identification of lithologic traps presents significant ambiguity.Based on actual drilling data and the sedimentary patterns in this area,the lithologic and lithofacies planar distributions are redefined,identifying favorable geological facies belts for reservoir development.Seismic response characteristics of different lithologic combinations are analyzed to pinpoint favorable reservoir development waveform features and seismic facies belts.By combining seismic and geological data,sensitive attributes are selected for reservoir prediction research.This approach has led to the identification and confirmation of several potential lithologic trap targets,effectively guiding lithologic reservoir exploration in this area.
