Shengli Oilfield Breakthrough: Patented Low-Shear Valve Solves Key Polymer Injection Challenge
A critical technology breakthrough at Shengli Oilfield is enhancing polymer flooding efficiency. The traditional problem? Standard control valves cause severe mechanical shear to the polymer solution, degrading its essential viscosity. This forced the inefficient "one pump, one well" model, limiting productivity and increasing costs.The main stop valve product names of China Stop Valve Network include:ANSI Flange Straight-through Globe Valve,Angle-type Ammonia Globe Valve,
Electric Flange Straight-through Globe Valve,Flange Straight-through Low Temperature Globe Valve,GB Bellows Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,
Pneumatic Flange Straight-through Globe Valve,Y-type Butt Welded Globe Valve
To solve this, technicians at the Gudong Oil Production Plant innovated a balanced low-shear regulating valve, now secured with a national patent. This valve directly addresses the industry's viscosity retention pain point through three core innovations:
1.Low-Shear Flow Path: A conical valve core and arc-shaped fluid channel minimize mechanical shear on polymer chains during regulation.
2.Durable Sealing: Wear-resistant alloy materials welded to sealing surfaces enhance erosion resistance and long-term reliability.
3.Balanced Regulation System: Sealed pressure reduction technology ensures flexible, stable, and precise flow control.
Proven Field Results: Since its 2005 trial in Gudong's District Two, this patented valve enabled efficient single-pump injection to multiple wells. Key verification data after six months shows:
1.High adjustment accuracy for polymer mother liquor.
2.Simple, reliable operation.
3.Exceptional viscosity retention rate consistently above 98% across various openings, preserving the solution's oil-displacement effectiveness.
This Shengli Oilfield patent solves a major production bottleneck. It boosts equipment utilization, improves oil recovery efficiency, and provides vital support for cost-reduction and advanced tertiary oil recovery techniques.
