Detached Flows at Rock Salt Exposition to Aqueous Solution

The results of experimental and field studies of breakaway currents when the solution affects rock salt are presented. Experiments are carried out on the samples of rock salt kern from the interval of underground shell-reservoirs for hydrocarbons storage, on the cubes of salt (models of vertical wells), large-scale horizontal models under field conditions. For the first time, it is found that during the mass transfer, when the solution affects the rock salt, a complex mechanism of various breaks of the boundary layer is formed: concentration detachment, surface detachment due to surface roughness (ledges of the trough), detachment at sedimentation of insoluble inclusions from salt—mechanical detachment, vortex detachment at formation of surface vortices, mechanodynamic break-off at the salt plate removal from the crystal, gas break-off at gas emission from rock salt (gas-mechanodynamic break-off at the salt plate removal and gas emission from the crystal, gas-metho-crystal break-off at gas emission from intercrystalline space). © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
