specific Embodiment approach

[0039] The mechanical hydraulic pumping unit with rocking effect of the present invention comprises a hydraulic power unit (1), a base (2), a hydraulic actuator (3) and a balancing system (4), which consists of a pulley and a counterweight ( 4) constitute the system. The power unit (1), base (2), hydraulic actuator (3) and balancing system (4) raise and lower the weight generated by the artificial lift mechanism installed at the bottom of the oil well.

[0040] The pumping unit of the invention also has a base layer (2.1) for the base on which the base (2) is mounted. This base has in the upper part a balancing system (4) comprising at least two movable pulleys (4.1) through which cables (4.2) The fixed pulley (4.4) of the weight device (4.3) connects the weight generated by the artificial lift mechanism with the counterweight device (4.3). Likewise, a hydraulic actuator (3) is mounted above the base (2) connected to the weights generated by the artificial lift mechanism. T...

[0043] Example 1: Structure of the mechanical hydraulic pumping unit with rocking effect according to the invention

[0044] On the premise of an industrial plant, cutting of pipes for assembly of the structure of the power unit and base. First, the metal sheets for the case, box, base, and base layer are cut using plasma.

[0045] Next, the base is welded to the cutting elements with plasma that form the structure of the power unit and holes are made in the base for mounting sensors and valves.

[0046] Next, assemble the motor and bell. Mechanizing the flexible coupling between the pump and the motor and the flexible coupling between the shaft and the motor has the purpose of extending the flexible coupling and being able to place it on the distal side of the ventilator. Also, connect the radiator parts and filter elements.

[0047] Assemble and connect electrical systems including cables, hydraulics, and hoses.

[0048] Furthermore, the piston, cover and actuator housin...

Abstract

The present invention relates to a hydraulic mechanical pumping unit with rocking effect, which comprises a compact-design power unit, a pedestal, a hydraulic actuator and a rocking system composed of movable pulleys, a fixed pulley and counterweights.

Description

technical field [0001] The present invention relates to the field of mechanical engineering, in particular mechanical engineering as applied in the field of petroleum engineering, and more particularly in techniques and equipment for artificial lift of hydrocarbons. Background technique [0002] A mechanical hydraulic pumping unit is a device used to perform artificial lift of crude oil found in the ground. For this purpose, a hydraulic system consisting of a series of individual elements is used. Typically, these pumping units use motors and other elements to generate the power required to perform the process of fluid and artificial lift of the lifting mechanism. [0003] In particular, Colombian Patent Application No. 10130183 describes a mechanical hydraulic pumping unit comprising a hydraulic power module and a base with hydraulic actuators. The invention works when the first pump of the dual system takes the hydraulic oil in the hydraulic tank and sends it as pressuri...
