【摘要】 从研究砂泥岩阻抗特征入手,通过多井合成记录分析地震反射与砂泥岩对应关系,结合模型正演分析,总结出温米地区砂泥岩地震响应特征及沉积特征。在此研究的基础上,运用多属性提取与地震相分析相结合,初步圈定岩性圈闭;运用沿层雕刻、时间切片、测井约束反演等技术手段综合运用,确定河道展布,并圈定岩性边界,在温五-红胡区块的应用中取得良好效果。更多还原

【Abstract】 From starting with the research on impedance characteristics of sandstone and shale, analyzing the seismic reflection and the corresponding relation between sandstone and shale by multi-well synthetic traces, combining with the analysis of forward model, seismic response and depositional characteristics of sandstone and shale in Wenmi oilfield is able to be presented. Based on the study, combining multiattribute extraction with seismic facies analysis, lithologic traps can be delineated. Several integrated technical measures, such as carving along layer, time slices as well as logging constraining inversion were integratedly used to confirm the channel distribution and delineate the lithogy boundaries, which have got good application effects in block Wen 5-Honghu.更多还原
