Embodiment Construction
[0026] First of all, it needs to be explained that the underground storage in this example is built on underwater natural rock mass. Therefore, before the construction of the underground storage, the underwater natural rock mass needs to be surveyed on site to obtain the basic underground rock mass. The basic data includes the rock properties, structural characteristics, in-situ stress, earthquake distribution, intensity and topography of the underground rock mass; among them, the earthquake can cause sudden damage to the built underground storage, and the in-situ stress can damage the built underground Storage tanks cause slow damage. For example, the accumulation of ground stress is often released in the form of earthquakes or rock bursts, and its damage to underground storage tanks is also extremely serious. These basic data are very important for the construction of underground storage. Specifically, existing technologies can be used to measure natural rock masses, such as u...

The invention discloses a construction method for constructing a non-metallic underground liquid gas reservoir by using a natural rock mass. The construction method includes the steps that the underground rock mass is surveyed, the basic data of the underground rock mass is obtained, and the basic data includes the rock mass nature, structural characteristics, ground stress, seismic distribution,strength and topography of the underground rock mass; a three-dimensional underground rock mass model is constructed through virtual constructed modules is constructed base on the rock mass nature andthe structure characteristics of the underground rock mass, the virtual environment of the three-dimensional underground rock mass, under the virtual environment, the underground reservoir is excavated by the virtual constructed modules on the three-dimensional underground rock mass, and the stress distribution is conducted on the three-dimensional underground rock mass under the condition of goaf through the virtual constructed modules; and by using the excavation of the underground reservoir in the virtual environment and the stress distribution under the excavation condition as guidance,the real underground reservoir is excavated by using excavation equipment in the surveyed underground rock mass, and the real underground reservoir includes the depth, size and shape of excavation. The invention further discloses a system by using the construction method.
Description
Technical field [0001] The invention relates to the field of liquid gas storage, in particular to a construction method and system for constructing a non-metallic underground liquid gas storage by using natural rock mass. Background technique [0002] The storage of liquid gas such as oil and natural gas is ground storage, that is, the corresponding storage is built on the ground to store the liquid gas; if the corresponding liquid gas explosion occurs, the ground storage has a devastating risk, and the risk is uncontrollable. Therefore, underground storage has become a research hotspot for liquid gas storage. However, the current underground storage is constructed with metal plates, which is not only costly, but also that metal plates are easily corroded after long-term use, which poses certain safety risks. Summary of the invention [0003] The technical solution adopted by the present invention to solve its technical problem is: a construction method for constructing a non-meta...
