Good-stability gas storage device for carbon dioxide flooding

Abstract

The invention discloses a good-stability gas storage device for carbon dioxide flooding. The device comprises a gas storage tank body, the bottom of the gas storage tank body is fixedly connected to a connecting plate, moving wheels are fixedly connected to the four ends of the bottom of the connecting plate, and a threaded rod is rotatably connected to the position, located in the center of the front portion of the gas storage tank body, of the connecting plate. A rotating knob is fixedly connected to the other end of the threaded rod, the threaded rod is sleeved with a lifting plate, an open groove is formed in the center of the lifting plate, the air storage tank body penetrates through an open groove, fixing boxes are fixedly connected to the four ends of the bottom of the lifting plate, sleeving plates are fixedly connected into the fixing boxes in a sleeving mode, and third springs are fixedly connected to the sleeving plates. The rotating knob rotates to drive the threaded rod to rotate and drive the lifting plate to move, so that the fixing boxes move downwards, a placement plate is driven to move downwards, the height of the placement plate is gradually close to and lower than that of the moving wheels, the placement plate touches the ground, and the whole device is fixed to the ground.

Description

technical field [0001] The application relates to a gas storage device, in particular to a gas storage device for carbon dioxide flooding with good stability. Background technique [0002] Carbon dioxide flooding technology is a technology that injects carbon dioxide into the oil layer to increase the oil recovery rate of the oil field. When carbon dioxide and formation crude oil first contact, they cannot form miscible phases, but under the conditions of suitable pressure, temperature and crude oil components, carbon dioxide can form miscible phases. leading edge. The supercritical fluid will extract the heavier hydrocarbons from the crude oil and continuously concentrate the gas at the displacement front, so that the carbon dioxide and crude oil become miscible liquids, forming a single liquid phase, which can effectively decompose the formation Crude oil is displaced to production wells. [0003] When carbon dioxide is injected into the oil layer through carbon dioxide ...

AI Technical Summary

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 gas storage device generally needs to be transported by moving wheels, but it cannot be fixed during use, and it may move, resulting in stability. Poor, and when the external force collides with the gas storage device, the gas storage device will be damaged
