Zhongyuan oilfield applications TaiBang 3GR screw energy saving technology
China Sinopec Zhongyuan Oilfield Group actively promote the use of a variety of new technologies, the construction of " energy-efficient oil extraction plant " in the promotion and application of wax wells screw technology. 3GR screw pumps driven by rotation of the screw downhole , will give rise to the liquid surface . The technology ease out 150 wells since the trial has achieved remarkable results, compared with the original by pumping oil , not only can save more than 200 kWh of electricity a day, and greatly improves the recovery , lie well cycle is significantly reduced. So I ordered the plant in a 20 3GR screw .
Our in-depth study of foreign advanced technology, according to China's current oil and gas multiphase actual requirements developed 2W.WH external bearing double suction pump twin-screw multiphase transport and 2W.W series twin screw pump , and GB11035-89 << >> marine electric twin-screw pump manufactured in accordance with the provisions of the national standard . With the main pump by the mutual engagement of the driven screw , and the screw and the bushing hole , forming a sealed cavity in the pump body when the screw is rotated, the continuous forward movement of a sealed cavity , the sealed chamber to promote the outlet of the liquid to achieve the purpose of pumping the liquid.
● 3gr screw pump structural features:
The double suction pump structure , screw both ends at the same pressure chamber , the axial force can be self- balancing. Externally mounted bearings at both ends , used alone lubricant (grease ) lubrication, thus not affecting transport medium between the two screw drive with a pair of synchronized gears , do not touch the tooth surface between the screw , while leaving a small gap , medium impurities does not have a direct wear ( except scour outside ) to screw the tooth surface .
Except for some small-displacement pump outside (2w.w4.0 less ) , usually in the pump comes with the flow valve, when the discharge pressure exceeds the rating, there is a protective effect . Import and export orientation on the pump there are two , one for horizontal feed , level out ; two horizontal into the vertical upwardly ; Users can choose according to their needs .
● twin-screw pump advantages:
1, the transmission fluid smooth , pulseless , without stirring , vibration, low noise.
2 , has a strong self-absorption properties, when multiphase transport , gas rate is not higher than 80% , sediment concentration is not higher than 500g/m3.
3 , external bearing structure , using an independent lubrication, can transport a variety of non -lubricating media.
4, using synchronous gear drive , no contact between the two rotors, even a short time idling anyway.
