Fracturing slickwater and fracturing fluid online continuous mixing device and using method

Abstract

The invention relates to afracturingslickwater and fracturing fluid online continuous mixing device, which comprises a base, the top end of the base is fixedly connected with a roots pump, the other side of the roots pump is fixedly connected with a leading-in pipe, the other end of the leading-in pipe is fixedly connected with a storage tank, a feeding mechanism is installed in the storage tank,two bearing plates are arranged in the feeding mechanism, and the two bearing plates are connected with the two sides of the storage tank in a welded mode correspondingly. According to the device, mother liquor can be stored through the storage tank, a hydraulic telescopic rod can drive a cover plate to move up and down to block or expose the open end of the storage tank, the mother liquid can beadded through the opening end of the storage tank, after liquid adding is completed, the opening end is blocked, so that dust and impurities can be prevented from entering the storage tank to pollutethe mother liquid and cause blockage of the device, and through a second motor, a stirring paddle can be driven to rotate to stir the mother liquor in the storage tank, and the situation that the mother liquor is precipitated and solidified can be prevented.

Description

technical field [0001] The invention relates to an online continuous mixing device for slick water and fracturing fluid for fracturing, and belongs to the technical field of continuous mixing equipment for fracturing fluid. Background technique [0002] In the process of acid fracturing construction, it is necessary to use clean water and mother liquid to configure two liquids, slick water and fracturing fluid, in a certain proportion. By adjusting the amount of mother liquor to meet the required ratio of construction equipment, so that the configuration of slick water and fracturing fluid can meet the construction design requirements. [0003] The existing slick water and fracturing fluid online continuous mixing device for fracturing, during its use, the carrier for storing mother liquor is exposed for a long time, which easily causes dust and impurities to accumulate for a long time, making its interior blocked, reducing the discharge of mother liquor transportation. amo...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problems of the existing on-line continuous mixing device for slick water and fracturing fluid used for fracturing. The carrier for storing the mother liquor is exposed for a long time, which is easy to cause dust and impurities to accumulate for a long time, making its interior blocked, and reducing the delivery capacity of the mother liquor. And through the previous gear pump, the pump body is easily corroded, which will easily lead to the problem that the sealing performance of the gear pump is weakened.
