PRODUCT ADVANTAGES

     After years of improvement and modifications, we broke through a number of technical barriers in the course of designing and manufacturing servo  drive, submersible motor and shaft couple and succeeded in developing this submersible screw pump intelligent oil production system which has the      following unique advantages:

    1. Having no bulk of pumping unit and the sucker rod, it takes a much smaller space, is free of noise and leakage at wellhead, and ensures better         safety.

Get rid of the portion of pumping unit on the groud and the sucker rod and avoid the use of a great deal of steel

Free it from the possibility of rod braking off, rod tube wear and tear, and power loss

Save the vost on foundation construction

Highly reliable and more cost-efficient in maintenance

1. 2.

Overall efficiency elevation, outstanding power-saving benefit, and less power consumption compared to like products.


A. Long system life and complete with all kinds of protection means
    Require no reducer and have longer life
    Designed with overload, overvoltage, under-voltage, and short circuit protection
    The permanet magnertic synchronous motor operates against degaussing
    An addition of PCP reversal ratation laocking is provided


B. Oil extraction under intelligent constant dynamic liquid level helps to avoid pump “dry abrasion”

    The combination of the ground submersible servo controller and the well liquid depth gauge helps to achieve control of fluid level in a closed loop, preventing the occurrrence of PCP dry abrasion due to insufficient liqyid supply.



C. Digital remote intelligent control can be realized

    Well data real-time collection 
    Well remote ON/OFF control
    Well fluid yield regulation
    Well operation condition diagnosis
    Well alarm monitor
    Free of field manual maintenance


3. Suitable for oil extraction in heavy oil wells and oil wells carrying sand or gas, and less prone to airlock



Type	Aoolication
Conventional (Pumping Unit)	Not suitable for stripper wells and heavy oil wells
Ground PCP	Not suitable for directional wells
Electric Submersible Centrifugal Pump	Sensitive to sand/gas where blades are susceptible to dameage, and not suitable for stripper wells and heavy oil wells
Electric Submersible Progressing Cavity Pump	Suitable for stripper wells and heavy oil wells but is restricted by the technical problem with reducer
ESPCP System	Suitable for exploitation in heavy oil wells and sand/gas wells and Directional/Horizontal wells
