Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to an oilfield additive mixer. Background Art

[0002] When exploiting an oil field, in order to increase the recovery rate of the oil field, there are primary oil recovery, secondary oil recovery and tertiary oil recovery. Primary oil recovery relies on natural energy, and secondary oil recovery uses water injection to supplement energy. Tertiary oil recovery is referred to as "three recovery", which uses other measures to increase the recovery rate. Injecting additives into oil wells to increase the recovery rate is a common way. The additives mainly contain two or more of drilling fluid emulsifiers, oilfield foaming agents, clean fracturing fluid thickeners, acidizing chemicals, oil displacement active agents, drainage active agents, clay stabilizers, low interfacial tension chemicals, oilfield wetting agents, etc., and the additives need to be stirred evenly when mixing.

[0003] At present, a Chinese utility model with a publication number of CN214862734U discloses a three-production auxiliary agent mixing device for oilfields. This utility model relates to a three-production auxiliary agent mixing device for oilfields, including a tank body, a supporting foot, a first liquid inlet pipe, a second liquid inlet pipe, a discharge pipe, a stirring motor, a stirring shaft and a stirring part; the tank body is arranged at the upper end of the supporting foot, the first liquid inlet pipe and the second liquid inlet pipe are respectively arranged at the upper end of the tank body, the discharge pipe is arranged at the lower end of the tank body, and a control valve is installed on the discharge pipe; the stirring shaft is rotatably assembled in the tank body, the upper end passes through the tank body and is fixedly docked with the output shaft of the stirring motor, and the stirring part is fixed on the stirring shaft; the three-production auxiliary agent mixing device for oilfields also includes a dispersion cylinder, a dispersion hole is opened on the dispersion cylinder, the dispersion cylinder is arranged at the upper end of the tank body, the dispersion cylinder is sleeved and fixed on the circumferential side of the stirring shaft, and one end of the first liquid inlet pipe and the second liquid inlet pipe inserted into the tank body extends above the dispersion cylinder; so that the raw material liquid is dispersed into the tank body, which is conducive to uniform mixing of the materials.

[0004] According to the above patent, when the existing oilfield additive mixer is in use, a rotating dispersion cylinder is used to achieve centrifugal rotation of the liquid material added thereto, thereby dispersing the material and then adding it to the tank body for mixing, so as to improve the efficiency and speed of subsequent uniform mixing. However, it is unable to scrape the inner wall of the tank body when mixing the liquid material, so that the material is easy to stick to the wall after long-term stirring, which is not conducive to subsequent cleaning and wastes resources. After the dispersed liquid material is added to the tank body, it only adopts a single stirring direction, which is not conducive to the mixing speed of the liquid material. Therefore, the above patent is improved according to the problems raised. Utility Model Content
