SYSTEM AND METHOD OF PREPARING FLUID FOR PROCESSING NEAR-WELLBORE ZONE Russian patent published in 2018 - IPC E21B43/267 E21B21/06 B02C23/20 

FIELD: technological processes.

SUBSTANCE: system and method are disclosed for preparing a fluid for processing near-wellbore area, comprising loading packets containing a coated coating additive into a first-container storage area; passing the packets to the bag shredder; the destruction of the envelopes of the packets to open the additive; passing the uncoated additive into the mixer; passing the aqueous solution from the second container to the mixer and mixing the uncoated additive with an aqueous solution to produce a fluid for processing the near-wellbore zone. First container may also contain a proppant storage zone of the first container, and then the proppant is passed from the proppant storage zone of the first container to the mixer. Fluid for processing the near-wellbore zone can be injected into the well that passes into the interior of the subterranean formation. System and method may also include a container in fluid communication with the first container and divided into a container storage area and a proppant storage area of the container.

EFFECT: technical result consists in increased efficiency of preparation of the fluid for processing the near-wellbore zone.
