SYSTEM FOR ARRANGEMENT OF HEAVY OIL AND NATURAL BITUMEN DEPOSIT Russian patent published in 2019 - IPC E21B43/20 

FIELD: oil industry.

SUBSTANCE: invention relates to system for arrangement of heavy oil and natural bitumen deposits. System for arrangement of heavy oil and natural bitumen deposit includes production wells connected through well production pipeline to demulsifier dosage unit, group metering unit, booster pump station and oil treatment unit, which is equipped with well product heating system via fuel gas pipeline, is equipped with commercial oil pipeline, associated petroleum gas pipeline and associated water production pipeline, which is communicated with treatment facilities and through the purified water pipeline is communicated with the cluster pumping station and the corrosion inhibitor dosing unit in the water conduit communicated with injection wells. Through the second pipeline of purified water treatment facilities are connected with a water treatment unit, which is connected through a sewage pipeline to a cluster pumping station, and through a pipeline of deep water with a steam generator, which is connected to a pipeline of fuel gas, and through a steam line is communicated with steam-injection wells. Treatment facilities are equipped with a pipeline of trapped oil for its return to the oil treatment plant. Water treatment unit is connected to a fresh water source through a fresh water pipeline. Between the treatment facilities and the water treatment unit, an additional water purification unit is installed, which is a filter unit using a filter material based on aluminosilicate rocks. Unit of additional water treatment is interconnected by pipeline of caught oil with oil treatment unit.

EFFECT: high efficiency of operation.
