The role of PHPA in fracturing fluids
The role of PHPA in fracturing fluid
Thickening effect of PHPA in oilfield:
PHPA, also named partially hydrolyzed polyacrylamide can significantly increase the viscosity of the fracturing fluid. A high-viscosity fracturing fluid can better carry proppants into formation fractures, providing efficient diversion channels for oil and gas, thereby increasing the production of oil and gas wells. PHPA ensures a more uniform distribution of proppants in the fractures and avoids local accumulation or absence.
Sand suspension performance of PHPA in oilfield:
Due to the thickening effect of PHPA, PHPA endow the fracturing fluid with good sand suspension ability. This enables the proppants to be uniformly suspended in the fracturing fluid and prevents premature settlement of the proppants during the fracturing process, thus ensuring the effectiveness and stability of the fracturing operation.
Adjusting rheological properties of PHPA in oilfield:
The rheological properties of the fracturing fluid can be adjusted according to different formation conditions and construction requirements. In complex formation environments, by changing the molecular structure and concentration of PHPA, the fracturing fluid maintains appropriate viscosity and performance to adapt to special formation conditions such as high temperature and high pressure.
Protecting the reservoir of PHPA in oilfield: Reduce the damage of the fracturing fluid to the reservoir and reduce the loss of reservoir permeability. After the fracturing operation, PHPA in oilfield can be discharged from the formation through degradation or flowback, reducing the long-term impact on the reservoir.
