Description

technical field [0001] The invention relates to a method for simulating the flow field and the concentration field of the water-soluble cavity of a salt rock opposite well. Background technique [0002] In the process of salt rock mining and salt rock water-solution cavity building process, whether the shape of the cavity can be well controlled is an important factor related to the recovery rate of the salt mine and the success of cavity construction. At present, domestic and foreign studies on water-solution cavity-making of wells mostly focus on the dissolution characteristics, cavity stability and mechanical properties, and there are few analysis of the flow field migration law and concentration distribution characteristics of well-salt rock solution cavity from the perspective of flow field. The flow field of the well dissolution cavity is also limited to numerical simulation calculations, and there are few physical model experimental data. Contents of the invention ...
