The role of drag reducer in fracturing fluid
The role of drag reducer in fracturing fluid
Drag reducing agent composition:
Drag reducing composition are diverse, with different chemical structures and compositions, which may be polymers, surfactants or other special chemicals. Generally, drag reducing agent with specific molecular structure designs can achieve the function of reducing the flow resistance of fluids in pipelines.
Different types of drag reducing agent composition perform differently in terms of solubility, stability and other aspects.
Reducing frictional resistance about drag reducer in oilfield:
Drag reducing agent can significantly reduce the frictional resistance when the fracturing fluid flows in pipes and wellbores. This reduces the energy required to pump the fracturing fluid, thereby reducing construction costs and increasing the injection rate of drag reducer in fracturing fluid and speeding up the progress of the fracturing operation.
Improving construction efficiency:
Due to the reduction in frictional resistance, smaller power pumping equipment can be used, which can effectively reduce equipment investment and operating costs. Under the same equipment conditions, a higher injection volume of drag reducer in fracturing fluid can be achieved, improving construction efficiency.
Improving the flow state: Make the flow of the drag reducing agent in fracturing fluid in pipes and wellbores smoother, reducing the generation of turbulence and vortices, and helping to improve the sand-carrying capacity and stability of the drag reducing in fracturing fluid.
