摘要(Abstract)：

为了进行孤东油田开发中后期有利储集体的预测和开发，以孤东油田四区主力小层Ng31为例，通过地震沉积学、地震资料和测井资料在储层中划分不同次级单元，识别构型单元类型及其组合体，对曲流河储层构型进行细致解剖。在正演的指导下建立复杂曲流河带及其内部单元的特征模型；应用模型对研究区进行地震构型解剖，结合动态资料和测井曲线进行验证，地层的吸水情况反映了砂体连通情况，解释结果反映了废弃泥岩的存在，验证结果与构型解释结果吻合，证明了河流相地震构型解释方法的可靠性。研究成果为下一步高效开发剩余油起到有效的指导作用，并对类似河流相储层构型研究有较好的借鉴意义。
In order to predict and develop favorable reservoirs in middle and late stages of oil field development, the main sublayer Ng31 in Block 4 of Gudong oilfield is selected for case study. Seismic sedimentology, seismic data and logging data are used to divide reservoirs into different orders of units, identify reservoir architecture unit types and their assemblages, and characterize meandering river reservoir architecture. The characteristics model of complex meander belts and their internal units is built with forward modeling, and is used to dissect seismic architecture of studied area. Validated with dynamic data and logging curves, the water absorption of stratum reflects sand bodies connectivity, and the interpretation reflects the presence of abandoned mudstone. Validation results tally with architecture interpretation, proving the reliability of fluvial facies seismic architecture interpretation method.The research plays guiding role in further effective development of remaining oil in Shengli Oilfield, and provides reference for study of similar fluvial reservoir architectures.
