摘要： The present invention relates to a system for treatment of a mixture from a production well, said mixture comprising a first aqueous liquid and a second oily liquid, the treatment system comprising an extraction tube installed in said well and capable of conducting said mixture from the bottom of said well, a separator capable of separating the first liquid from the second liquid in said mixture, a first end of said tube being connected to the separator, a first injection means capable of injecting a first product into said tube, said first product being capable of improving the flocculation and coalescence of the second fluid in the mixture. Any diameter of the tube between said first end of the tube and a second end of said tube lies in an interval of 10% around a predetermined diameter.

摘要： The present invention relates to a liquid evacuation device for an extraction well. The device comprises a tank presenting a liquid accumulation area. The tank is connected to a gas evacuation tubing. An insulant limits a flow of fluid between a wall of the tank and a wall of the well, from a first space formed between the insulant and the well bottom to a second space formed between the insulant and the well head. A first opening on the tank enables circulation of a gas-liquid mixture from said first space to a third space formed in the gas evacuation tubing. A second opening on the tank enables circulation of fluid from said second space to the liquid accumulation area. The first opening is made between the liquid accumulation area and the connection to the evacuation tubing.
