Liquid supply device

Abstract

The invention discloses a liquid supply device, and belongs to the technical field of detection. The liquid supply device comprises a first manifold assembly, a booster pump and a plurality of second manifold assemblies; the booster pump is provided with a plurality of booster outlets and a plurality of booster inlets; each second manifold assembly comprises a second outlet and a plurality of second inlets, the plurality of second inlets correspond to a plurality of liquid carbon dioxide storage tanks in a one-to-one mode, each second inlet is configured to be connected to the corresponding carbon dioxide storage tank, the plurality of second manifold assemblies correspond to the booster inlets of the booster pump in a one-to-one mode, and the second outlets of each second manifold assembly is connected to the corresponding booster inlet; and the first manifold assembly comprises a first outlet and a plurality of first inlets, the plurality of booster outlets are connected to the plurality of first inlets in a one-to-one correspondence mode, and the first outlet is configured to be connected to a fracturing blender truck. The problem that the supply amount of liquid carbon dioxide in the fracturing blender truck is unstable due to the fact that the fracturing blender truck cannot be connected to a plurality of low-pressure pipelines at the same time in the prior art is solved, and the effect of improving the liquid supply continuity and stability is achieved.

Description

technical field [0001] The present application relates to the technical field of detection, in particular to a liquid supply device. Background technique [0002] Carbon dioxide water-free fracturing technology is a technology that injects liquid carbon dioxide into the reservoir as a sand-carrying fluid during the production of oil and gas wells to increase reservoir production. Liquid carbon dioxide is injected into the sand mixer, and then the mixed The final carbon dioxide sand-carrying fluid is injected into the reservoir, because when injected into the reservoir, a large amount of continuous sand-carrying fluid can get better fracturing effect, therefore, the continuous and stable supply of liquid carbon dioxide to the sand mixer has become one of the technologies. unresolved issues. [0003] A liquid supply device in the prior art includes a plurality of carbon dioxide liquid storage tanks and a plurality of low-pressure pipelines, one end of each low-pressure pipeli...

AI Technical Summary

Problems solved by technology

[0004] In the process of implementing the present application, the inventor found that the above method has at least the following defects: due to the limited connection port of the sand mixing vehicle, multiple low-pressure pipelines cannot be connected at the same time, and the carbon dioxide storage tank needs to be replaced in time when there is insufficient liquid during the liquid supply process , resulting in unstable supply of liquid carbon dioxide in the mixer truck
