Displacement test device and displacement test method

Abstract

A displacement test device and a displacement test method are provided, relating to the technical field of displacement tests. The displacement test device includes a displacement fluid system, a core holder, and a nuclear magnetic resonance instrument. A fluid outlet of the displacement fluid system communicates with a fluid inlet of the core holder, and a core is arranged in the core holder. The displacement fluid system can transport a displacement fluid into the core holder, the core holder can displace a target fluid from the core, and the core holder is arranged in a detection cavity of the nuclear magnetic resonance instrument. According to the displacement test device and the displacement test method, shale can be detected during shale displacement test, and a displacement test effect can be evaluated well.
