Area of Science:

  • Colloid science and materials science
  • Petroleum engineering and enhanced oil recovery

Background:

  • Conventional gel plugging agents are ineffective in hot-water drive oil reservoirs due to temperature fluctuations.
  • High permeability layers in reservoirs like Bohai Oilfield require adaptable plugging solutions for efficient hot water flooding.

Purpose of the Study:

  • To develop a smart plugging reagent that responds to temperature changes in dominant reservoir channels.
  • To enhance the recovery rate of hot water drive mining in thick oil reservoirs.

Main Methods:

  • Formulation of a temperature-sensitive gel system using cellulose ether, nanosilica, HEDP·4Na, and urea through physical cross-linking.
  • Evaluation of injection, plugging, scouring resistance, and cooling/plugging removal performance in porous media.
  • Optimization of system composition and salinity to control gelation temperature between 50-100 °C.

Main Results:

  • The optimal composition (cellulose ether 1#, nanosilica, HEDP·4Na, urea) achieved over 96% plugging rate in high-permeability media (3000-7000 × 10-3 μm2).
  • The gel system maintained stable high pressure (above 4.5 MPa) after 11 pore volumes of water injection.
  • Effective temporary blockage and significant pressure reduction after cooling (52 °C) demonstrated reversible plugging capabilities.

Conclusions:

  • The developed smart plugging system exhibits excellent plugging ability and stability under harsh reservoir conditions.
  • The system shows significant fluid diversion effects, improving water absorption profiles in reservoirs with permeability ratios of 4-8.5.
  • This technology offers a promising solution for enhancing thick oil thermal recovery in challenging oilfield environments.
