Abstract: The present invention corresponds to a check valve with an inertial mass that is installed in the bottom of the production tubing and above the progressive cavity pump (PCP) of an oil well, which prevents that the hydrostatic column that is inside of the production tubing go down in the moment where the artificial lift of the column stops for the detention of the PCP pump. If we prevent that this phenomenon to happen, the PCP pump will not rotate in the opposite direction of its normal operation and it will not be clogged by any particulate material that is contained in it.

Abstract: The invention corresponds to a mechanical hydraulic pumping unit with a radiator integrated to the chassis and a hydraulic circuit which allows it to operate with high flow rates and low pressure or with low flow rates and high pressure. This mechanical hydraulic pumping unit with a radiator integrated is used to supply a particular pressurized oil flow to a hydraulic actuator, which in turn lifts the load exerted by a string of rods and lift the hydrostatic column that is inside an oil well. The main feature of this mechanical hydraulic pumping unit with a radiator integrated is that the radiator is part of the machine's chassis and is located in the middle of two hydraulic oil tanks. The first of these tanks is the oil suction tank, while the second is the oil return tank.

Abstract: The present invention relates to an improved mechanical pumping hydraulic unit for use in oil production or hydrocarbon extraction. The unit is characterized in that it has one motor (1-25), which activates a dual pump (1-15) at one end of the shaft and activates a fan (1-26) at the opposite end of the same shaft. The dual pump (1-15) provides power to the hydraulic power circuit (1-13) and to the hydraulic recirculation circuit (1-14). The motor (1-25), along with the pump (1-15) and the fan (1-26), are inside a metal structure (1-8), or focusing element, which serves to propel air sent by the fan (1-26) through the radiator (1-14-3) and to protect all the components of said unit, such as a tank (1-3) for the hydraulic oil, a compartment or casing for the electrical components (1-5), and a component or dry chamber (1-2) for the hydraulic instrument panel (1-7).

Abstract: The invention relates to an artificial lifting system comprising a progressive cavity motor for hydrocarbon's extraction. In the invention's system a pump injects a fluid stored in the surface to the progressive cavity motor, located in the basement; the rotation that occurs by the passage of fluid is transmitted to a progressive cavity pump such that the hydrocarbon is pushed toward the surface.
