Abstract

The invention provides a method and a device for establishing a geomechanical model of a salt-cavern gas storage group, which are used for providing scientific and effective data support for evaluation of a to-be-established salt-cavern gas storage such as an ultra-deep salt-cavern gas storage group and ensuring reasonable selection of the to-be-established salt-cavern gas storage such as the ultra-deep salt-cavern gas storage group.

Description

technical field [0001] This application relates to the field of geology, in particular to a method and device for establishing a geomechanical model of a salt cavern gas storage group. Background technique [0002] With the rapid development of economy and society, China's demand for energy is increasing day by day. Huge energy demand, high dependence on foreign oil and gas, and weak peak-shaving supply capacity make it urgent to establish a complete energy reserve system. The salt cavern underground gas storage has the advantages of safety, high efficiency and stability, flexible injection and production mode, high gas injection and production rate, and large short-term throughput. Since the world's first salt cavern underground gas storage began to operate in the 1960s, In 2020, there will be more than 100 operating gas storages in the world. Considering the limited storage capacity and working gas volume of single-cavity gas storages, in order to meet the needs of market...
