The invention relates to an artificial system for simultaneous production and maintenance with mechanical pumping with flexible tubing for fluid extraction, which includes: a surface assembly that includes a sub-base, a hydraulic traction head, a stuffing box, an annular seal blowout preventer, a slip blowout preventer and a means for connecting and coupling; a production string extending vertically down into a well from the surface assembly; a well casing; a flexible pipe located inside the production string, extending the entire length thereof, the well casing, the production string and the flexible pipe remaining one inside the other concentrically; and a pumping assembly that includes a connector, a check valve, a cleaning tool and a stationary pump. The system enables production with a mechanical pump for the extraction of fluids, and maintenance by the simultaneous pumping of chemical products to said well to modify the physical properties of the fluid to be extracted and to clean the deposit of organic and inorganic material in the well. |
