Problems solved by technology

[0005] In order to overcome the fact that the current acid fracturing drag reducer is not ground after its production is completed, resulting in the production of acid fracturing drag reducer with a small specific surface area, when the acid fracturing drag reducer is used, its efficacy cannot be fully exerted, and currently During the production of drag reducing agent, solids are usually directly mixed with liquid, resulting in agglomeration of solids, and the current grinding equipment usually requires additional equipment to pressurize, thereby increasing the friction between drag reducing agent and the rotor and stator of the grinder For the disadvantage of impact force, a mixing and grinding device for ultra-fine powder of drag reducing agent based on the principle of fluid mechanics is provided

Abstract

The invention relates to the technical field of drag reducing agent mixing, in particular to a drag reducing agent ultrafine powder mixing and grinding device. At present, the acid fracturing drag reducer is not ground after the production is completed, resulting in a small specific surface area of ​​the acid fracturing drag reducer, and its effect cannot be fully exerted when the acid fracturing drag reducer is used. A resistance reducing agent ultrafine powder mixing and grinding device comprises a grinding mechanism, the upper part of the grinding mechanism is provided with a mixing and pressing mechanism, the upper part of the mixing and pressing mechanism is provided with a stirring mechanism, and the upper part of the stirring mechanism is provided with a feeding mechanism. The present invention grinds the generated suspension emulsion type drag-reducing agent by setting a grinding mechanism, thereby increasing the specific surface area of ​​the drag-reducing agent, making the reaction between the drag-reducing agent and the acidifying fracturing fluid more sufficient, and achieving better performance through the grinding mechanism. Grinding effect, better pressurization effect is achieved by the mixing and pressurizing mechanism, better stirring effect is achieved by the stirring mechanism, and better mixing effect is achieved by the feeding mechanism.

Description

technical field [0001] The invention relates to the technical field of drag reducing agent mixing, in particular to a drag reducing agent ultrafine powder mixing and grinding device. Background technique [0002] In the process of oil and gas well development in oilfields, for some oil and gas wells in deep or low-permeability areas, it is usually necessary to add acidizing fracturing fluid to prevent the fractures from being completely closed after the pump is stopped to release pressure. In the process of cracking, it is usually necessary to add a drag reducing agent to reduce the friction between the acid fracturing fluid and the pipeline, thereby increasing the fluidity of the acid fracturing fluid. The raw materials of the drag reducing agent are polyacrylamide, emulsifier and initiator. agent, etc. [0003] At present, the acid fracturing drag reducer is not ground after the production is completed, resulting in a small specific surface area of ​​the acid fracturing d...
