Device for preparing fracture acidifying fracturing fluid with high viscosity and low resistance reduction

Abstract

The invention provides a device for preparing fracture acidifying fracturing fluid with high viscosity and low resistance reduction. The device comprises a tank body, a mixing cylinder, a stirring unit and a power unit, part of the mixing cylinder is located in the tank body, and the mixing cylinder is provided with at least one raw material inlet and a communication port communicated with the tank body; the stirring unit comprises a rotating shaft, first shearing blades and second shearing blades, and part of a shaft body of the rotating shaft is located in the mixing cylinder; the first shearing blades are arranged on the shaft body of the rotating shaft in the mixing cylinder body; the second shearing blades are arranged on the inner wall of the mixing cylinder; at least one second shearing blade is arranged in each of the upper direction and the lower direction of each first shearing blade; and the power unit can drive the rotating shaft to drive the first shearing blades to stir fracturing fluid raw materials. The device has the following beneficial effects: the overall liquid preparation speed is increased, meanwhile, the contact time of operators and various chemical raw materials is shortened, and the body health and life safety of the operators are guaranteed.

Description

technical field [0001] The invention relates to the technical field of fracturing and acidizing oil and gas wells, in particular to a device for preparing high-viscosity, low-resistance fracturing acidizing fracturing fluid. Background technique [0002] In view of the high-temperature and high-pressure sulfur-containing characteristics of the Sinian and Longwangmiao reservoirs in the Gaomo area, the Lower Permian in western Sichuan, and the Lower Paleo-Sinian in eastern Sichuan, with the development of deep well and ultra-deep well acidizing technology, fracturing and acidizing operations The acid solution system is constantly changing and innovating, the construction scale is increasing day by day, and the safety and environmental protection requirements are more stringent. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to solve one or more problems in the above prior art. For example, one of the ...
