Area of Science:

  • Petroleum Engineering
  • Materials Science

Background:

  • Ultra-deep reservoir hydraulic fracturing faces challenges: high wellbore friction and thermal instability of conventional fluids.
  • Existing fracturing fluids lack the necessary thermal stability and friction reduction for extreme conditions.

Purpose of the Study:

  • To develop a novel weighted fracturing fluid for ultra-deep reservoirs.
  • To address limitations of conventional fluids regarding friction and thermal stability.

Main Methods:

  • Formulation of a potassium formate-weighted fluid using a hydrophobic associating polymer and organic zirconium crosslinker.
  • Investigation of fluid properties: density (1.4 g/cm³), crosslinking time (300 s at 90 °C), and friction reduction (63.2%).
  • Evaluation of dual-network structure formation above 60 °C and retained viscosity after shearing (75.3 mPa·s at 200 °C).

Main Results:

  • The fluid exhibits delayed crosslinking and superior temperature resistance.
  • A dual-network structure provides enhanced thermal and shear stability.
  • Effective gel breaking achieved using sodium bromate.

Conclusions:

  • The developed fluid reconciles low wellbore friction with high-temperature proppant-carrying capacity.
  • Presents a superior fracturing fluid and an innovative technique for ultra-deep reservoir development.
