摘　　要：东营凹陷盐家油田砂砾岩体为快速堆积而成的近岸水下扇沉积,内部结构复杂,地层划分与对比难度较大。本文运用井—震联合分析技术对砂砾岩体内幕进行精细解剖,划分出多期水道,并刻画了单期水道的横向展布及空间分布形态。在此基础上,运用测井INPEFA旋回分析技术对单期水道内部进行精细划分与对比,为后续油田注水开发提供地质依据。The glutenite in Yanjia oilfield of Dongying Depression is a fast piled-up nearshore submarine fan deposition,its inner structure is complex,as a result it is difficult to conduct stratigraphic division and correlation.In this paper well-to-seismic joint analysis technique was used to conduct detailed interpretation for the episode of the glutenite,multiple water channels were classified,and lateral and spatial distribution of single water channel was delineated.Based on the analysis above well logging INPEFA cycle analysis technique was utilized to conduct detailed division and correlation for the episode of single water channel,the analysis results achieved could provide geological basis for further oilfields water-flooding development.
