Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0023] In general, there is a significant difference in the parameter requirements for salt mining in underground salt mines and cavity building in salt caverns. Salt mining in underground salt mines has higher requirements on parameters such as the amount of salt to be extracted, but lower requirements on parameters such as cavity shape....

Abstract

The embodiment of the invention discloses a salt cavern store mining parameter test apparatus and a method thereof. The apparatus comprises a barrel body, a tray, a collet and a cover plate, wherein the barrel body is transparent; the cover plate is covered on the opening of the barrel body, the cover plate is provided with a clamping portion used for clamping salt rocks to be tested, and the clamping portion is positioned in the barrel body and stretches downward when the cover plate covers the opening of the barrel body; and the collet is arranged at the bottom in the barrel body, and the tray is arranged above the collet. Requirements of salt cavern store mining design are met on the basis of mining parameters obtained through the test apparatus and the method in the embodiment of the invention.

Description

technical field [0001] The present application relates to the field of water-solution cavity-building of underground storage, and in particular to a device and method for testing parameters of cavity-building of salt-cavern storage. Background technique [0002] Salt cavern storage is a cave storage space artificially formed by water dissolution in thicker underground salt layers or salt domes to store oil and natural gas, which can be used for peak regulation and strategic reserves. The key technology for building salt cavern storage is salt cavern cavity building. The size and shape of the cavity are mainly determined by geological conditions. Therefore, before building salt cavern storage, it is necessary to fully understand the structure, composition and other conditions of the salt layer in order to study how to build a safe and stable cavity in the underground salt layer. Generally, simulation experiments can be carried out indoors to determine the influence of cavit...
