Abstract

The invention provides a mixing system of fracturing fluid, which comprises a first mixer, a base fluid supply piece and a powder supply piece; the first mixer is a jet mixer, and a base fluid input end of the first mixer is connected with the base fluid supply piece; a powder input end of the first mixer is connected with the powder supply piece, and the first mixer is linked in parallel with a parallel pipeline capable of conveying the base fluid; the base fluid input end of the parallel pipeline is connected with the base fluid output end of the base fluid supplier, and the first mixer is linked with a second mixer in series; the second mixer is a variable flow jet type mixer, a fracturing fluid input end of the second mixer is connected with a fracturing fluid output end of the first mixer; the base fluid input end of the second mixer is connected with the base fluid output end of the parallel pipeline. The mixing system of fracturing fluid can meet the emission and fluid viscosity of the fracturing fluid simultaneously.

Description

technical field [0001] The invention belongs to the technical field of fracturing, and in particular relates to a fracturing fluid mixing system and a mixing method using the mixing system. Background technique [0002] Fracturing technology refers to a method of using liquid pressure to form cracks in oil and gas reservoirs in the process of oil or gas production. The specific operation is to use high-pressure and large-displacement pumps and use the principle of liquid pressure transmission. A liquid with a certain viscosity (that is, fracturing fluid) is injected into the reservoir at a pressure greater than the absorption capacity of the reservoir, and then sand-filled fractures with a certain geometric size and high conductivity are formed in the formation near the bottom of the well, so that The well achieves the purpose of increasing production and injection. Since the current fracturing construction sites at home and abroad (especially shale gas fracturing construct...
