Device and method for obtaining position of liquid displacement surface in rock fracture

Abstract

The invention provides a device and method for obtaining the position of a liquid displacement surface in a rock fracture. The top end of a water tank communicates with a gas pressurizing device usedfor providing a stable pressure. The device comprises normal stress frames, a rock crack simulation sample used for a simulation experiment is installed between the normal stress frames through a supporting plate assembly, and a plurality of high-speed cameras used for monitoring the experiment process are arranged on the periphery of the rock crack simulation sample; and a water outlet in the bottom end of a water tank is communicated with a crack communicated with the rock crack simulation sample through a high-pressure water pipe. Therefore, the motion loss rule of the filler can be directly observed, researchers can conveniently observe the displacement operation rule from the plane and the vertical plane, and the device has the advantages of being visual in observation, easy to operate and convenient to collect data.

Description

technical field [0001] The invention relates to the field of liquid displacement in rock fractures, that is, a method for obtaining the position change of the displacement surface at any time by innovating and upgrading the traditional displacement method. Background technique [0002] The displacement process has applications in many aspects of industrial production. If the knowledge and understanding of the displacement process can be improved, the utilization rate of raw materials and production efficiency of industrial production will be improved. For the displacement process, traditional instruments and methods are generally used to study the displacement process in the actual construction process. The advantage is that the production cost is lower and the investment in operating equipment is less. But at the same time, the disadvantage is that usually only the materials at the inlet and outlet (such as outlet pressure, inlet pressure, flow velocity, etc.) can be used ...
