In order to eliminate the disadvantages arising from the traditional thermal method of impact, we offer to supply equipment for continuous heating of the bottom-hole zone of wells in order to reduce the viscosity of oil, eliminate colmatation and prevent the formation of asphalt-resin-paraffin deposits in the bottom-hole zones of wells, working bodies of ESP, on the inner walls of pipes.
Equipment for heating:
• Stationary well electric heater
• Heating control station with high voltage transformer
One of the effective methods of intensification of oil inflow and increase of productivity of production wells is artificial increase of temperature in a trunk and in its bottom-hole zone.
When warming up the bottom–hole zone is achieved:
• the decrease in the viscosity of oil;
• reduction of surface tension at the oil – rock-oil interface –water;
• transfer to liquid phase some solid deposits, for example, asphalt and paraffin;
• increased mobility of the fluid displaced from the reservoir.
