Abstract

The present disclosure provides a visualization model, a visualization device and method of gas overburden phenomenon, wherein the visualization model includes: a model body; inlet pipes and outlet pipes respectively connected to opposite ends of the model body; at least two pipes formed in the model body A layer of pore network structure; and a shunt pipe formed in the model body and connecting each layer of the pore network structure with the inlet pipeline and the outlet pipeline; wherein, the projections of each layer of the pore network structure on the horizontal plane do not overlap . The visualization model, visualization device and method of the gas overriding phenomenon provided in the present disclosure are used to realize the visual observation of the gas overriding phenomenon in the gas drive process.

Description

technical field [0001] The present disclosure relates to the technical field of experimental equipment for oil exploitation, and in particular to a visualization model, a visualization device and method for gas overburden phenomena. Background technique [0002] Using various types of gas to drive oil is an effective method to enhance oil recovery, but due to the density difference between gas and liquid, gas overburden will be formed under the action of gravity. Contents of the invention [0003] Some embodiments of the present disclosure provide a visualization model, a visualization device and method for gas overburden phenomena, so as to realize the visualization of gas overburden phenomena during displacement experiments. [0004] On the one hand, a visual model is provided, including: a model body; inlet pipes and outlet pipes respectively connected to opposite ends of the model body; at least two layers of pore network structures formed in the model body; and, forme...
