本申请实施例提供一种地下井间单河道砂体的对比方法和装置，该方法包括：获取监测井中检测到的由注入井注入的示踪剂的检测信息；根据检测信息，计算井间砂体的连通性参数，其中，连通性参数表示注入井和监测井之间的砂体连通性能；根据连通性参数，确定注入井和监测井之间的砂体连通状况；根据砂体连通状况，从复合河道中识别出单河道砂体并进行对比，其中，复合河道由多条单河道砂体拼合叠置形成。本申请实施例通过示踪剂来精准地确定注入井和监测井之间的砂体连通状况，进而能够避免地下井间河道砂体对比不确定性的问题。 An embodiment of the invention provides a contrast method and a contrast device for single river channel sand bodies between underground wells. The contrast method comprises the steps of: acquiring detection information of a tracer agent which is injected from an injection well and detected in a monitored well; calculating connectivity parameters of interwell sand bodies according to the detectioninformation, wherein the connectivity parameters indicate sand body connectivity between the injection well and the monitored well; determining the sand body connecting situation between the injection well and the monitored well according to the connectivity parameters; and identifying the single river channel sand bodies from a composite river channel according to the sand bod
