Ground driving screw pump sand rotation device and method

The invention discloses a ground driving screw pump sand spinning device and method, a sucker rod, a screw pump and a sand spinning device are sequentially connected to the lower end of a driving head, meanwhile, a liquid discharge hole and a sand discharge hole are formed in the sand spinning device, the sand spinning device is driven by the screw pump to quickly rotate to generate centrifugal force, so that oil, sand and gas are separated, and the sand spinning effect is improved. Sand enters the pipe column on the lower portion through the sand discharging hole, oil liquid enters the screw pump through the liquid discharging hole, the oil liquid and sand grains are effectively separated, the device does not depend on centrifugal force of rotation of the liquid, oil and sand separation can be achieved through separating force generated by the sand cyclone, the device is suitable for being applied to displacement oil extraction of various scales, and the device is suitable for popularization and application.
