Problems solved by technology

[0003] When carbon dioxide is injected into the oil layer through carbon dioxide flooding technology, it is generally necessary to use a gas storage device to store the carbon dioxide. The general gas storage device is often provided with rollers at the bottom for easy movement. When the gas storage device is used, the rollers will The stability of the gas storage device will be affected, and the gas storage device will move when it is placed; when the general gas storage device is exhausted, the internal carbon dioxide gas may be difficult to get rid of; when the gas storage device collides, the impact force may be relatively large. Large, may cause damage to the gas storage device

Abstract

The invention discloses a gas storing device for carbon dioxide flooding. The gas storing device comprises a gas storing tank, a carbon dioxide opening, a first valve, a first air pump, an air pipe, arubber air bag, handles, elastic buffer rods, rubber balls, moving rods, fixing sleeves, springs, ball nuts, first screw rods, first screwing blocks, moving trundles, first plastic soft sleeves, second plastic soft sleeves, supporting rods, second screw rods, second screwing blocks, a second valve, fixing blocks, rotating rings, fixing rings, annular grooves, fixing plates, threaded holes, shortpipes, a three-way pipe, second air pumps and one-way valves. The structure is rational. The device can be used for gas supply for carbon dioxide flooding in oil and gas field development. Through a moving structure, the gas storing tank can move on the ground. When moving is not required, the moving trundles are lifted and are not in contact with the ground, and a ground inserting structure is arranged in a matched mode. Stability during application of the gas storing tank is guaranteed, and moving is avoided.

Description

technical field [0001] The invention relates to a gas storage device, in particular to a gas storage device for carbon dioxide flooding, and belongs to the technical field of oil and gas field development and application. Background technique [0002] Petroleum is a viscous, dark brown liquid that is stored in parts of the upper crust. In the development of oil and gas fields, carbon dioxide flooding technology is often used to inject carbon dioxide into the oil layer, which can effectively increase the oil recovery rate of the oil field. [0003] When carbon dioxide is injected into the oil layer through carbon dioxide flooding technology, it is generally necessary to use a gas storage device to store the carbon dioxide. The general gas storage device is often provided with rollers at the bottom for easy movement. When the gas storage device is used, the rollers will The stability of the gas storage device will be affected, and the gas storage device will move when it is pl...
