INTEGRATED SUPPLY IN PROCESS AT DRILLING SITE Russian patent published in 2019 - IPC E21B43/26 

FIELD: mining.

SUBSTANCE: group of inventions relates to underground operations of well treatment in oil and gas industry, and in particular to formation hydraulic fracturing. Device for mixture formation provides for use of mixing unit. This assembly comprises a frame and a rheological inspection assembly. Rheology control unit comprises a means for receiving the first material from the first transporting mechanism, a dispersion and / or mixing system connected to the frame, and a first dosing system. This system is configured to dispense the first material from the first material receiving material into the dispersion and / or mixing system. Dispersion and / or mixing system is configured to disperse and / or mix the metered first material with fluid to form a first fluid mixture. There is a unit for mixing of coarse solid fraction. This assembly comprises means for receiving second material from second conveying mechanism. Second material is a material of a coarse solid fraction. There is a solid fraction mixing system connected to the frame and a second metering system configured to dispense the second material from the second material receiving material into the solid fraction mixing system. Solid fraction mixing system is configured to mix the dosed second material with the first fluid mixture to form a second fluid mixture.

EFFECT: technical result is increased efficiency of operations of formation treatment, including hydraulic fracturing, and reliability of device operation.
