The complete set of electric submersible screw pump is a new type of oil production equipment combining the advantages of electric submersible pump and screw pump. The ground drive of screw pump is changed to be driven by efficient submersible motor, and the sucker rod is removed. The problems of trip, broken rod and partial wear caused by the screw thread and coupling are solved, and the pump inspection period is extended.
Compared with other oil production equipment, the system has the advantages of wide adaptation range, no rod wear, easy management, high efficiency and energy saving, etc. The equipment is suitable for various well types, such as rod pump, submersible electric pump and other common heavy oil Wells, gas Wells, small displacement Wells, directional Wells and horizontal Wells that are difficult to operate.
Our company has conventional external cable type electric submersible screw pump, cable internal fishing type electric submersible screw pump, small diameter integrated upside down electric submersible screw pump, upper screw pump without duct cap structure, can meet the needs of different working conditions.



(1) small diameter integrated inverted electric submersible screw pump unit

1, the maximum outside diameter of the motor 89mm, according to the power of different motor length 2.5-4m
2. The maximum outer diameter of the integrated unit is 110mm and the maximum length is less than 10m
3, the lower screw pump structure, can choose a variety of sand and gas prevention schemes

(2) The upper duct structure of the electric submersible screw pump unit

1. The maximum outer diameter of the motor is 114mm and the length is 2.5m
2, screw pump structure, the flow hood is not hanging motor special design structure, to ensure effective overflow and gas liquid separation at the same time, effectively control the outside diameter size, the maximum outside diameter of the flow hood 110mm

(3) the upper screw pump without the shield structure of the electric submersible screw pump

Using 2.5m small size high efficiency submersible motor matching the upper type high efficiency anti-gas screw pump, can be in the case of no increase in the guide hood, not affected by certain gas, to meet the production requirements
