Definitions
- the present invention relates to a system for the extraction of fluids from a well that does not have sufficient oil field energy to raise the produced fluids to the surface, in particular, an artificial production system assisted by mechanical pumping with flexible pipe for fluid extraction, and maintenance by simultaneous pumping of chemicals to said well to modify the physical properties of the fluid to be extracted and clean the deposit of organic and inorganic material in the well.
- the oil is extracted by drilling a well over a reservoir.
- the pressure in the well is sufficient, it will force the natural exit of the oil through the well for its subsequent treatment and / or distillation.
- the rod pump system is used (also known as pump jack, horsehead pump, beam pump, sucker rod pump, etc.) which is the surface part of an impeller piston pump.
- Rod pump systems are common in oilfield extraction and their size is determined by the depth, the inside diameter of the pipe inside the well and the density or viscosity of the oil to be extracted, where deeper extraction requires more energy to move longer lengths of the fluid column.
- a crank-crank mechanism converts the rotary movement of the motor to an alternative vertical movement that moves the pump rod, and produces the upper to lower repetitive movement.
- Rod pumps are driven by a motor. Said motor moves a pulley system that in turn connects to a connecting rod, to compensate for the weight of the rod string that reaches the bottom of the well.
- the connecting rod goes up and down a crank connected to the end of a beam, at the other end of the beam, is the head.
- a cable made of steel connects the head with the polished rod, which passes through a sealing box, allowing it to move in and out of the pipe without fluid leaking from the well (The pipe runs to the bottom of the well).
- a reciprocating pump which contains two valves: a stationary valve and a valve in the piston connected to the end of the rods with trajectory upper and lower, known as the "traveling valve".

- the subsoil pump is held in the well and is driven by repetitive upward and downward movements of the tube.
- the subsoil pump pumps liquids to the surface through the intubation column.
- This patent describes a system that uses a tube to "move" a reciprocating pump, however the system is exclusive for the extraction of oil and in case of failures or breakdowns that prevent its operation all the equipment must be disassembled, including the one that is found in the basement, for repair.
- the system extracts oil exclusively through the concentric pipeline, freeing the piping column.
