An artificial simultaneous production and maintenance system assisted by mechanical pumping with flexible tubing for fluid extraction, comprising: a surface assembly including a sub-base, a hydraulic drive head, a stuffing box, an O-ring preventer, a wedge preventer and a connection and splicing means; from the surface assembly a production tubing extends vertically downwards inside the well bore; a casing; a flexible tubing located inside the production tubing all along its length, being the casing, the production tubing and the flexible tubing concentrically one inside the other; and a pump assembly including a connector, a check valve, cleaning tool, standing pump. The system allows assisted production by mechanical pumping for fluid extraction and maintenance by simultaneous pumping of chemicals to the well to modify physical properties of the fluid to be extracted and clean organic and inorganic material buildup within the well. |
