Embodiment Construction
[0039]The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope. After reading the present invention, those skilled in the art will understand the present invention Modifications of various equivalent forms fall within the scope defined in the present application.
[0040] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions are for the purpose of illustration onl...

The application discloses a jet cleaning simulation experiment system for a salt cavern gas storage, including: a cavity; a cover; a flushing mechanism and a flowback mechanism whose lower end extends into the cavity; the flushing mechanism includes: a flushing main column and a flushing branch connected to it There is at least one flushing branch column, and the lower end of the flushing main column and the flushing branch column can be detachably connected with a rotary jet nozzle; the first flushing valve; the second flushing valve; the flowback mechanism includes a sleeve set outside the flushing main column The flowback main column and the flowback branch column connected with the flowback main column, there is at least one flowback branch column, and there is a predetermined distance between the flowback port and the rotating jet nozzle; the first flowback valve; the second flowback A discharge valve; a liquid injection device for injecting cleaning liquid into the flushing mechanism; a flowback recovery device connected with the flowback mechanism. This application can simulate the process of jet cleaning the insoluble matter in the salt cavern gas storage cavity, and reveal the influence of cleaning methods, cleaning displacement, injection pressure and other factors on the cleaning efficiency.
Description
technical field [0001] The invention relates to the technical field of cleaning insoluble matter in a salt cavern underground gas storage, in particular to a jet cleaning simulation experiment system for a salt cavern gas storage. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] The salt cavern underground gas storage is to use the thicker salt layer or salt dome underground to store oil and natural gas in the salt layer or salt dome through water dissolution to form a cave cavity storage space. As a good carrier for storing natural gas, salt cavern cavity has important strategic significance in my country's West-East Gas Transmission Project. [0004] The salt rocks available for reservoir construction in my country generally have the characteristics of mainly layered, many ore layers, thin single layers, and high content of insoluble impurities.
