Electric drive water powder continuous mixing device

Abstract

The invention relates to the technical field of fracturing fluid preparation devices, and is an electric-driven water-powder continuous mixing device, which includes a powder bin, a powder feeding device, a water-powder mixer, a vertical pipeline centrifugal pump and an electric control cabinet. In the operating state of the present invention, powder can be randomly added to the powder bin, so that the device can continuously feed powder, and a spare water-powder mixer and a spare vertical pipeline centrifugal pump can be added to ensure that the device can work continuously without interruption when the instrument fails. To improve work efficiency, the invention adopts an electric driving force system, rationally utilizes the power grid of the oil field to obtain electricity, and the power drive does not burn oil and gas, and does not emit carbon dioxide into the atmosphere, which has environmental protection value, and can precisely control the mixing ratio of water and powder to ensure the mixing quality , remote control through the electric drive system, reducing the process, greatly reducing the work intensity of the operator, the integrated setting of the skid seat, effectively reducing the input cost of production, which can meet the use requirements in the liquid distribution station, and can also be used for fracturing on-site operations .

Description

technical field [0001] The invention relates to the technical field of fracturing fluid preparation devices, and relates to an electric drive water powder continuous mixing device. Background technique [0002] Fracturing is one of the main measures to increase the production of oil and gas wells in the tertiary oil recovery of oil fields, and it is widely used in various oil fields. The working fluid used in fracturing operations is usually called fracturing fluid. Over the past decades, domestic and foreign oil fields have conducted extensive research on fracturing technology, and developed from the initial thickened water fracturing fluid to the later natural plant jelly fracturing fluid, foam fracturing fluid, and acid-based fracturing fluid. Various fracturing fluid systems, such as fracturing fluid, emulsified fracturing fluid, oil-based fracturing fluid, clean fracturing fluid, etc. The fracturing fluid system is gradually becoming more and more perfect, playing an i...
