摘　　要：涠西南凹陷W油田古近系浊积岩油藏具有埋藏深、个体小、隐蔽性强等特点,常规地球物理勘探技术难以有效识别;加之受欠压实作用的影响,区内低速泥岩发育,进一步增加了浊积岩油藏储层预测难度。针对上述问题,通过开展地震资料拓频保幅处理及声波曲线重构技术等研究,总结出一套适合涠西南凹陷浊积体储层预测的技术及流程。该技术应用于勘探开发实践,并取得了较好效果,表明该技术对整个盆地岩性油藏勘探具有一定的指导意义和推广价值。The Paleogene turbidite reservoir is characterized by deep burial,small bodies and strong concealment of W oilfield in Weixi’nan Sag,it is difficult to identify the turbidite reservoir by conventional exploration technology.Due to under-compaction,low-velocity mud stone develops in the study area,which further increases the difficulty of turbidite reservoir prediction.In view of above problems,a set of technology for turbidite reservoir prediction in Weixi’nan Sag was summarized by studying seismic extension frequency and amplitude preserving processing and acoustic curve reconstruction.This technology has been applied to exploration and development practice,and has achieved good results,indicating that this technology has a good guidance and popularization value for lithologic reservoir exploration in the whole basin.
