Area of Science:

  • Petroleum Engineering
  • Reservoir Engineering
  • Enhanced Oil Recovery

Background:

  • Chemical profile control is vital for reducing water cut in heterogeneous reservoirs.
  • High costs and harsh reservoir conditions (high temperature, salinity) limit traditional methods.
  • Need for innovative solutions to improve oil recovery efficiency.

Purpose of the Study:

  • To investigate a novel multiphase mixed fluid system for enhanced oil recovery.
  • To elucidate the mechanisms of this system in heterogeneous reservoirs.
  • To address limitations of conventional profile control methods.

Main Methods:

  • Parallel sand pack experiments.
  • Transparent visualization plate displacement experiments.
  • Systematic investigation of fluid flow and blockage mechanisms.

Main Results:

  • The multiphase mixed fluid system effectively creates dynamic blockages in high-permeability channels via the Jamin effect.
  • Permeability reduction in high-permeability layers (2227 to 178 mD) achieved fluid redirection.
  • Increased recovery factor in low-permeability zones by 8.5% and confirmed via sand pack experiments.

Conclusions:

  • Multiphase mixed fluid technology offers a new approach for developing high-water-cut oilfields.
  • Intelligent blockage and energy redistribution enhance sweep efficiency in heterogeneous reservoirs.
  • This technology provides a viable alternative to overcome challenges in complex reservoir development.
