AI Technical Summary

Technical Problem

In the existing carbon dioxide injection device, the air conduit pipe cannot move in the vertical direction, and the carbon dioxide discharge at a specific precise position cannot be achieved, resulting in low injection efficiency.

Method used

A carbon dioxide oil-fighting and gas-fighting storage device in kerosene gas symbiosis area is designed, including a base, gas injection assembly, storage tank, conveying pipe and position adjustment assembly. The position adjustment assembly can drive the conveying pipe to move in the vertical direction, realizing the automatic re-movement of the conveying pipe in a specific precise position.

Benefits of technology

The stable, continuous supply and precise injection of carbon dioxide have been achieved, the efficiency of carbon dioxide injection has been improved, waste has been reduced, and safety has been enhanced.

Abstract

The invention relates to the technical field of carbon dioxide oil displacement, in particular to a carbon dioxide oil displacement and gas displacement sealing device for a coal-oil-gas symbiotic area. The gas injection assembly is arranged above the base; the storage tank is fixedly arranged at the top of the base, and the gas inlet end of the gas injection assembly communicates with the interior of the storage tank; the conveying pipe is arranged above the base, and the gas outlet end of the gas injection assembly communicates with the interior of the conveying pipe; and the position adjusting assembly is arranged above the base, and the output end of the position adjusting assembly is connected with the conveying pipe. When the device is used, the device is moved to a designated place through the base, the gas injection assembly can pump carbon dioxide in the storage tank into the conveying pipe, the conveying pipe discharges the carbon dioxide into the ground, and oil type gas, methane and coal bed gas can be pumped to the ground. The position adjusting assembly can drive the conveying pipe to move in the vertical direction, the position of the conveying pipe in the vertical direction can be freely changed, the conveying pipe automatically moves upwards again, and carbon dioxide is discharged at a specific accurate position.
