Abstract

The invention discloses a constant temperature and constant pressure seal test apparatus. The constant temperature and constant pressure seal test apparatus comprises a pedestal support, a pressure-control system, a temperature-control experiment system and a valve pipeline system. The pressure-control system comprises an energy accumulator and a pressure gage arranged on a pedestal; the temperature control experiment system comprises a crystallization cavity, an upper cover used for sealing is arranged on the crystallization cavity, a contact tube is arranged on the upper cover of the crystallization cavity, a solution introduction interface and a lower water outlet are arranged at a lower part of the crystallization cavity, a heating resistor is arranged in the crystallization cavity, the heating resistor is connected with a heating resistor interface arranged on the upper cover, a sensor is arranged on the upper cover; the energy accumulator is communicated with the crystallization cavity through a dimension pressure pipeline, and a dimension press valve and the pressure gage are arranged on the dimension pressure pipeline. The constant temperature and constant pressure seal test apparatus has the advantages of simple structure, high efficiency and convenience while in use, accurate temperature control, and long-term pressure control, and can be used for researching interacting phenomenon of defect rocks and a recrystallized substance of a saturated solution under constant temperature and constant pressure.

Description

technical field [0001] The invention relates to a constant temperature and constant pressure sealing test device, which belongs to the field of water-soluble mining indoor tests. Background technique [0002] The underground energy reserve of salt rock is built by water-soluble mining. High-pressure water is injected from the underground salt layer through the casing (inside), and the underground salt mine is dissolved in water to form saturated brine, which is discharged from the casing (middle) Discharge, such a cycle, the underground salt mine is continuously dissolved, thus forming a huge underground salt cavern cavity, because salt rock has extremely low permeability and good creep performance, so it becomes an ideal medium for underground energy storage. Water-solution cavity building is a very long process. It takes several years to build a salt rock underground energy storage cavity. During this process, due to the impact of mining activities, a cavity is formed in t...
