Description

Technical Field

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

[0002] Oilfield drilling and crude oil extraction require the use of additives. The two main additives used in oil drilling are oil well cement admixtures and drilling fluid treatment agents, while three commonly used additives in crude oil extraction are water plugging agents, fungicides, and acidizing corrosion inhibitors. Adding these additives requires a device, such as the Chinese utility model patent publication number CN210829220U, which specifically discloses an oilfield additive dosing device.

[0003] However, most of the current adding devices for oilfield additives do not have a mixing function. When using additives, there may be a situation where multiple additives need to be used, and the current adding devices are difficult to mix multiple additives together when used, which greatly reduces its practicality.

[0009] As a preferred embodiment of the present invention, an observation window is provided on the front of the adding tank, and a scale is provided on the side of the observation window. The observation window is mainly provided to facilitate observation of the material inside the adding tank.

[0010] As a preferred embodiment of the present invention, valves are provided on both the feeding port and the discharging port, and the feeding or discharging is controlled by the valves.

[0011] As a preferred embodiment of the present invention, a plurality of scrapers are fixed to the end of the stirring rod, and each scraper is in contact with the inner wall of the adding tank. The scrapers can be used to scrape off the materials in the adding tank during the mixing process.

[0012] As a preferred embodiment of the present invention, the outer side of the filter cartridge is provided with anti-slip grooves, and the anti-slip grooves are mainly provided to facilitate twisting the filter cartridge, so as to facilitate later disassembly and maintenance.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model can achieve mixing of additives added to the tank through the stirring assembly, ensuring that when adding multiple oilfield additives, multiple additives can be mixed together. By providing a filter cartridge at the discharge port and a filter screen inside the filter cartridge to achieve a filtering effect, impurities are avoided in the additives and the purity of the additives is improved.
