摘要:

曲流河砂体横向变化快,砂体内部构型具有复杂性和多变性。利用探地雷达(GPR),以平—剖结合的思路对新疆呼图壁河与额尔齐斯河砾石质曲流河段进行沉积模式研究,并综合现代沉积、无人机与遥感影像对GPR剖面进行解释。识别出4GPR相: 连续的亚平行低—中振幅反射、连续的顶平底凸型低—中振幅反射、连续倾斜中—高振幅反射以及不连续倾斜高振幅反射,分别对应河漫滩、废弃河道、点坝和滞留沉积4种沉积微相。通过总结砾石质曲流河垂向与横向沉积特征演变及交互作用,建立了多期次沉积模式,并构建了三维地质模型,为后期曲流河储集层预测及建模提供了精细构型组合规律和定量地质信息。

Abstract:

The meandering river sand bodies exhibit rapid lateral variability and feature complex and heterogeneous internal architectures. In this study,ground-penetrating radar(GPR)was employed in conjunction with a combined plan-view and cross-sectional approach to investigate sedimentary patterns in gravel-dominated meandering river segments of the Hutubi and Irtysh Rivers in Xinjiang. Interpretations of GPR profiles were supported by modern sedimentological observations,UAV imagery,and remote sensing data. Four distinct GPR facies were identified: (1)continuous subparallel low-to-medium amplitude reflections corresponding to floodplain deposits;(2)continuous flat-topped to convex-based low-to-medium amplitude reflections indicative of abandoned channels;(3)continuous inclined medium-to-high amplitude reflections characteristic of point bars;and(4)discontinuous inclined high-amplitude reflections associated with lag deposits. Through an integrated analysis of the vertical and lateral sedimentary evolution and their interactions in gravel-bed meandering systems,a multi-phase depositional model was developed. This model supports the construction of a three-dimensional geological framework,providing refined architectural configurations and quantitative geological information that offer valuable guidance for reservoir prediction and modeling in meandering fluvial systems.
