A concentration field monitoring device for salt rock indoor water-solution cavity-making test

Abstract

The invention discloses a concentration field monitoring device for indoor water-soluble cavity-making experiments in salt rock. The upright column, the rock salt support and the bottom plate support are respectively connected to the base through bolts, and the salt rock support is between the upright column and the bottom plate support; The columns are fixed and connected by bolts; the laser emitting module bracket is provided with a chute, the laser emitting module and the laser emitting module bracket are connected by bolts, and the laser emitting module is fixed in the laser emitting module bracket by tightening the bolts, the camera and the laser emitting module bracket The uprights are fixed and connected by bolts, and the camera can completely capture the picture on the bottom plate; the computer and the camera are connected by a data cable. The structure is simple, no need for multiple sampling and repeated operations, and it is convenient to use. The measurement accuracy based on the refractive index is high, and it is not affected by temperature, pressure, etc. The monitoring is carried out from the outside, and there is no interference with the concentration field of the indoor water-solution cavity-making experiment in salt rock. The monitoring density is high, and the concentration data of up to 10,000 coordinate points can be collected.

Description

technical field [0001] The invention relates to the fields of water-soluble mining of salt mines and cavity building of salt rock storage, and more particularly relates to a concentration field monitoring device for indoor water-soluble cavity building experiments of salt rock. The invention is applicable to the monitoring of the concentration field during the indoor water-solution cavity-making process of salt rock. Background technique [0002] At present, the use of salt rock caverns for underground storage of energy is increasing day by day. It is necessary to control the shape of salt caverns in the water solution mining of salt mines and the construction of salt rock reservoirs. The most important thing for the development of salt caverns is the brine in salt caverns. Therefore, it is necessary to explore the concentration distribution of brine in the salt cavity; [0003] It is too difficult to monitor the three-dimensional concentration of salt caverns, and the unde...

Problems solved by technology

[0004] The existing monitoring methods include the dye loss method and the sampling measurement method. Among them, the dye trace method needs to dye the salt rock, which is difficult, and the dye will interfere with the actual dissociation of the salt rock and the convection process of the brine. In addition, many parameters of the dye and salt are different, and cannot fully represent the migration and concentration distribution of brine; the sampling measurement method requires manual or mechanical collection of brine samples from different positions in the salt cavity for measurement and research, and the sampling density is small. Point layout is difficult, the efficiency is low, and the sampling process will interfere with the flow field in the salt cavity, which makes the experiment lose its authenticity

There is no means of high-density and high-precision real-time monitoring of the unevenly distributed brine concentration field in the closed salt cavity
