摘　　要：地质雷达探测技术(Ground-penetrating Radar,简称GPR)是一种用于确定浅层地下介质分布的广谱勘探地球物理技术。以海拉尔曲流河现代沉积为目标,探讨了如何应用地质雷达探测技术开展河流相储层构型表征及建立原型地质模型。地质雷达探测技术及实施过程具体包括目标区地质雷达资料采集、数据处理及剖面综合解释等环节,以河流相储层构型及沉积模式为基础的地质雷达剖面分析和解释是研究工作的核心。通过海拉尔地区目标的探测,共识别出了河道充填构型(CH)、侧向增生体(LA)、废弃河道沉积(FFCH)、洪泛细粒沉积(FF)4种曲流河储层构型单元,总结了各自的地质雷达响应特征以及构型界面识别标志,结合探槽、钻孔等其他信息,建立了目标区曲流河沉积三维原型地质模型。Penetrating Radar(GPR) is a broad-spectrum exploration geophysical technique that is used to determine the distribution of shallow underground media. In this paper,taking modern deposits of meander river in Hailaer as the target,we discuss how to use geological radar detection technology to characterize fluvial reservoir architecture and establish prototype geological model. The geological radar detection technology and implementation process include the target area geological radar data collection,data processing and comprehensive interpretation of the profile. The analysis and interpretation of the geological radar profile based on the fluvial reservoir architecture and sedimentary model is the core of the research work. Four meanded-river reservoir architecture units,channel filling architecture(CH),lateral accretion body(LA),abandoned channel deposit(FFCH),and flood finegrained deposit(FF),were identified by consensus through target detection in the Heilar area. Their geological radar response characteristics and recognition marks of configuration interface were summarized,combined with other information such as trough and borehole. The three-dimensional prototype geological model of meandering river deposition in the target area is established.
