A device and method for obtaining the position of liquid displacement surface in rock fractures

Abstract

The invention provides a device and method for obtaining the position of a liquid displacement surface in a rock fracture. The top of the water tank is connected with a gas pressurizing device for providing stable pressure; it includes a normal stress frame, and the normal stress frame is between the A rock crack simulation sample for the simulation experiment is installed through the support plate assembly, and a plurality of high-speed cameras are arranged around the rock crack simulation sample for monitoring the experimental process; the water outlet at the bottom of the water tank is connected with the high-pressure water pipe. The fractures connected to the rock fracture simulation sample are connected; the movement loss law of the filler can be directly observed, which is convenient for researchers to observe the displacement operation law from the plane and elevation. It has the characteristics of intuitive observation, simple operation and convenient data collection. .

Description

technical field [0001] The invention relates to the field of liquid displacement in rock fractures, that is, a method for innovating and upgrading a traditional displacement method so as to obtain the position change of the displacement surface at any time. Background technique [0002] The displacement process has applications in many aspects of industrial production. If the understanding 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 also less. But at the same time, the disadvantage is that the material at the inlet and outlet (such as outlet pressure, inlet pressure, flow rate, etc.) can usually only be...
