Embodiment 1

[0041] The special device for fracturing fluid mixing provided by the embodiment 1 of the present invention includes a mixing tank, a diffuser, a liquid outlet pipe, a liquid level adjustment structure, and a stirring structure. The mixing tank is provided with a first-in-first-out restriction liquid The diffuser is installed on the mixing tank body, the diffuser is connected with the inside of the mixing tank body, the liquid level adjustment structure and the stirring structure are both installed inside the mixing tank body, The liquid outlet pipe communicates with the bottom of the mixing tank.

[0042] The working principle of this embodiment is as follows: because the traditional liquid configuration is extremely easy to cause uneven mixing, the phenomenon of "powder in water" occurs, which seriously affects the work progress. In the present invention, the traditional fracturing fluid mixing form is changed, and the S-shaped liquid flow channel design of this scheme is used ...

Embodiment 2

[0044] The preferred embodiment 2 of the present invention provides a special device for mixing fracturing fluid, which includes a mixing tank, a diffuser, a liquid outlet pipe, a liquid level adjustment structure, and a stirring structure. The first-out S-shaped liquid flow channel, the diffuser is installed on the mixing tank, the diffuser is connected with the inside of the mixing tank, and the liquid level adjustment structure and the stirring structure are both installed inside the mixing tank, The liquid outlet pipe is communicated with the bottom of the mixing tank. The stirring structure includes a stirrer and a stirring motor, the stirrer is installed in the S-shaped liquid flow channel, and the stirrer is connected to the output end of the stirring motor. The liquid level adjustment structure includes a liquid level gauge and a liquid level adjustment plate, the liquid level gauge is installed inside the mixing tank, and the liquid level adjustment plate can be raised...

Abstract

The invention discloses a special device for mixing fracturing fluid, which relates to the technical field of oilfield fracturing equipment. The device comprises a mixing tank body, a diffuser, a liquid outlet pipe, a liquid level adjusting structure and a stirring structure, an S-shaped liquid flow channel for limiting first-in first-out of liquid is arranged in the mixing tank body; wherein thediffuser is installed on the mixing tank body, the diffuser is communicated with the interior of the mixing tank body, the liquid level adjusting structure and the stirring structure are both installed in the mixing tank body, and the liquid outlet pipe is communicated with the bottom of the mixing tank body, so that the powder-in-water phenomenon is avoided, the hydration viscosity of mixed liquid is greatly improved, and the mixing quality is improved.

Description

Technical field [0001] The invention belongs to the technical field of oilfield fracturing equipment, and specifically relates to a special device for fracturing fluid mixing. Background technique [0002] In oil field fracturing operations, the mixing quality of fracturing fluids is an important factor to ensure the success of fracturing operations. The traditional fracturing fluid mixing method is the intermittent method, that is, using a pool of water or a tank of water, relying on manual calculation and weighing of the required amount of each material, and then put the powder into the pool or tank according to the ratio, after a long time After time stirring and circulating dissolution, after mechanical stirring and circulating hydration, a prepared fracturing fluid is obtained. However, the quality of the fracturing fluid prepared by this manual intermittent liquid mixing method is poor, the "powder in water" is serious, the viscosity is uneven, and the intermittent operati...
