WATER PRODUCTION ISOLATION TECHNIQUES FOR OIL-WELLS WITH HIGH RESERVOIR TEMPERATURE

Advanced drilling technology makes it possible to penetrate oil and gas sites with deep bedding of reservoir, a complex multi-layer structure high reservoir temperature at the well bottom, reaching 150°C. The difficult geology strata leads fact that productive layers are flooded unevenly. In this work causes for water cut in reservoirs given, repair insulation technologies isolation water-bearing intervals oil-producing wells considered. Grouting composites inflow limitation low (up 100°C) high-temperature studied. For flood control viscoelastic extended gel-time stable strength adhesive properties has been proposed. advantage polymer-based is their kinetic behavior dynamic mode, when filtering porous medium, which isolate effectively intake formations different channel openings small flow rate mixture.
