“…The salt cavities formed after brine extraction and production are all gas storage resources that can be exploited and used. Compared with other natural gas storage facilities, salt rock is considered as the best underground natural gas storage site due to its low permeability, high ductility, creep properties and damage self-healing [7,8].…”

This study aimed to overcome the difficulty of conducting the horizontal-well cavity leaching test in the field and to investigate the long-term stability of the horizontal-well salt-cavity natural gas storage. The simulation test design is combined with the similarity theory to study the cavity expansion characteristics and the influence law of cavity leaching parameters. Through the design of a rubber hose connection, an integrated closed test system for multi-stage horizontal-well cavity leaching and brine drainage was built. The test system also realises the repeatable backward movement of the injection well during the test. A similarity simulation of the test design was carried out, and the test platform was constructed to carry out multi-stage horizontal-well leaching tests with a nitrogen cushion. In the horizontal-well leaching tests with a nitrogen cushion, the influence laws of the well spacing, flow rate and liquid level position on cavity expansion were investigated. Based on the morphological characteristics of the horizontal-well cavity, a numerical model of the horizontal-well salt cavity was developed, which reflects the real cavity morphology leached in the test. The long-term stability of the horizontal-well salt-cavity natural gas storage under different internal pressures was investigated through numerical simulation.

“…Compared with other natural gas storage media, salt rock is recognised as the best underground natural gas storage site due to its low permeability, high ductility, creep properties and damage selfhealing [11,12]. Since the first salt cavern natural gas storage was built in the Soviet Union in 1959, as of the beginning of 2020, 108 salt cavern natural gas storage facilities have been put into operation in 14 countries worldwide, with a working gas capacity of 32.346 billion m³ [13,14].…”

Based on the similarity theory, a large-size salt rock horizontal well cavity-leaching test platform was built, and horizontal-well cavity leaching tests with nitrogen cushion were carried out, and based on the cavity-leaching parameters, the extension characteristics of cavity morphology and the influence law of the cavity-leaching parameters were analysed; and through the establishment of numerical models reflecting the actual horizontal-well cavities morphology and characteristics, a long-term stability analysis of the horizontal well cavities was carried out, and in combination with the cavity morphology and characteristics, the distribution characteristics of the horizontal well cavity displacements and the plastic zones in the long-term operation were analysed.
