Detailed description

How it works
The is a cutting-edge technology product that integrates magnetic and fluid dynamics principles, designed specifically to work with rod-type pumping units. It effectively prevents wax and scale buildup, enhances pump efficiency, and boosts individual well productivity. The device is installed directly beneath the oil pump and above the screen pipe. Utilizing the energy from the pumping unit, as crude oil flows through this innovative device during production, its unique structural design generates cavitation effects and acoustic vibrations. Moreover, under the influence of a powerful, high-energy magnetic field, the device creates a synergistic coupling effect between acoustic and magnetic fields.
By altering the physical properties of crude oil—such as fluid flow rate, flow regime, temperature, pressure, viscosity, gas-liquid phase solubility, solid-liquid mixing degree, crystal precipitation temperature, and adsorption/growth environment—the microscopic structure of hydrocarbon components undergoes a series of physical and chemical transformations. This process results in highly soluble and emulsified produced fluids, effectively reducing crude oil viscosity, enhancing flowability, preventing wax and scale buildup in tubing, improving pump efficiency, and ultimately boosting well productivity. As a result, it delivers remarkable benefits in wax prevention, scale inhibition, viscosity reduction, and oil production enhancement.
