Oil-gas-sand three-phase separation equipment matched with oil field oil drawing

The utility model belongs to the field of crude oil separation, and particularly relates to oil-gas-sand three-phase separation equipment matched with oil drawing of an oil field. A feeding port is formed in the position, close to the upper portion, of the side face of the shell body, a cover plate is installed on the top face of the shell body in a riveted mode, an exhaust port is formed in the top of the cover plate, an oil discharging port is formed in the position, close to the bottom, of the side face of the shell body, and a sand discharging port is formed in the position, close to the center, of the bottom of the shell body. Centrifugal force is generated through rotation of the separation device, oil liquid is filtered out through filtering holes evenly formed in the surface of a filtering plate, the oil-sand separation effect is achieved, the device is conveniently limited through arrangement of a clamping groove and a limiting ring, the stability of the device during operation is improved, the oil l
