Abstract

The invention relates to the technical field of water-powder mixing or liquid mixing equipment in the construction operations of oil and gas fields and particularly relates to a fracturing base liquidmixer used in a construction process of an oil field fracturing site. The fracturing base liquid mixer comprises a rotational flow premixing device which comprises a liquid inlet, a feeding hole, a connecting component and an annulus, wherein the feeding hole is vertically formed, the liquid inlet is horizontally formed, the side wall of the feeding hole is connected with a sleeve, the connectingcomponent is arranged in the sleeve, the annulus is formed by the connecting component and the side wall of the feeding hole and is communicated with the liquid inlet, an oblique side is arranged atthe lower end part of the side wall of the feeding hole, an oblique plane is arranged at the upper part of the connecting component, and the oblique plane and the oblique side form certain angles witha vertical plane and are 0-80 degrees; and a reduced section, a throat pipe and a dispersion pipe are sequentially arranged at the lower part of the feeding hole. The fracturing base liquid mixer canmeet the requirements on the fracturing base liquid during large-scale operations in a fracturing operation site, the blending and mixing efficiencies are improved, the mixing quality of guanidine gum liquid is improved, and the optimal energy efficiency ratio is realized.

Description

technical field [0001] The invention relates to the technical field of water-powder mixing or liquid mixing equipment in oil and gas field construction operations, in particular to a fracturing base fluid mixer used in field construction of oil field fracturing. Background technique [0002] During oil testing or production of oil and gas wells, the production of oil and gas wells will be low due to pollution near the wellbore (drilling, cementing, well washing and killing processes will cause pollution) or low original permeability of the formation. This problem can be solved by fracturing technology. [0003] 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 reservo...
