Definitions
- the present invention relates to the field of mechanical engineering and has application in the hydrocarbon sector.
- the present invention has applicability in oil wells where said BCP pumps are used.
- the patent application, number 2006027513 "Fuel pump improvement system” presents a fuel supply system that includes a fuel pump, a controller, and a pulse circuit.
- the fuel pump has an electric motor that includes a winding configured to operate with maximum efficiency at a first voltage for an expected load.
- the controller includes a pulse width modulator to generate an activation signal for the electric motor.
- the circuit acts as a passing pulse and the excitation signal is modulated at the first voltage to control the pump output.
- the pulse circuit acts to scale the excitation signal to a second voltage that is greater than the first voltage.
- the second voltage drives the electric motor to a voltage beyond maximum efficiency, but in general it provides greater system efficiency.
- the patent application entitled Linear pump with exhaust pulsation attenuation with number 20060034709 describes a linear pump that has an axially aligned cylinder and piston arrangement driven by an electromagnet motor has an exhaust chamber that defines a covered cavity for a diaphragm
- the diaphragm can be moved into the cavity in response to pressure fluctuations in the exhaust chamber to attenuate pulsations in a stream of air exiting the exhaust chamber.
- a diaphragm is mounted on the cavity recessed by a support ring that has an open center allowing air to act against the diaphragm.
- BCP Progressive Cavity Pumps
- a surface machine consisting of a motor and a speed reducer is used, which is responsible for providing the rotation and the power necessary to move said pump.
- It also uses a string of rods, which connect the rotor of the BCP pump with the surface. These rods measure approximately 6 meters, but the string, which is the union of several, can measure between 300 m to 3000 m approximately; these rods transmit the power and the rotation of the machine from surface to the pump.
- the current problem is that when the BCP pump stops, the hydrostatic column on top of it causes it to rotate in the opposite direction of its normal operation.
- the present invention provides a check valve with inertial mass that is installed at the bottom of the production pipe and above the BCP pump of the oil well, which prevents the hydrostatic column present inside the production pipe from going down at the moment that the artificial lift is suspended as a result of the stopping of the BCP pump. Preventing this phenomenon from occurring means that the BCP pump does not rotate in the opposite direction to its normal operation and that it does not get stuck due to the particulate material that would be deposited in it.
- the check valve with inertial mass for progressive cavity pumps consists of eight components which are: an upper locknut, a rod, a piston, a piston cover, a nipple, a lower locknut, an inner gasket and an outer gasket.
- the piston moves axially through the rod and sits in the nipple where the hydraulic seal is made.
- the piston is not seated, it allows the artificial lifting of the fluid and due to its characteristic geometry it is embedded in the wedges of the upper locknut that is coupled to the upper left thread of the rod in order to rotate in a integral manner to the rod.
- This check valve for progressive cavity pumps is of inertial mass, refers to the weight of the piston.
- the weight of the piston improves the downward movement of the same, guaranteeing the closing action of the check valve with inertial mass for progressive cavity pumps.
- the check valve with inertial mass consists of eight main parts: an upper locknut 1, a rod 2, a piston 3, a piston cover 4, a nipple 5, a lower locknut 6, an inner gasket 17 and an outer gasket 18, as It is seen in figure 1.
- the stem 2 consists of a shaft made of medium alloy steel by machining procedures, which has threads 8 and 1 1 at its ends, in addition to two left threads 9 and 10, as shown in Figure 3.
- the thread upper left 9 is located next to the upper thread 8 while the lower left thread 10 is located next to the lower thread 1 1.
- To the upper thread 8 is connected a cuplin belonging to the string of rods that is connected to a motor with speed reducer on the surface of the well.
- the lower thread 1 1 is connected by a cuplin to a second string of rods that is connected to the rotor of the BCP pump.
- the lower locknut 6 is installed, in order to support the cuplin that is installed in the lower thread 1 1.
- the piston 3 consists of an inner groove 13 where the inner gasket 17 is installed that holds the liquids between the piston 3 and the rod 2, which can be observed in figure 4.
- it has a step 14 where the outer gasket 18 is installed which retains the liquids present between the nipple 5 and the piston 3, as seen in figure 4.
- the piston 3 also has a thread 15 in which the piston cover 4 is installed in order to hold and secure the position of the external gasket 18.
- the piston cover 4 has two parallel flat faces, as seen in figure 5, which serve as support for the tool used to thread the piston cover 4 on the thread 15 of the piston 3.
- the rod 2 is inserted through the piston 3 and is restricted by installing the upper locknut 1 on the upper left thread 8.
- the upper lock nut 1 It is characterized by having two wedges 7, as seen in Figure 2, which fit the wedge grooves 12 of the piston 3.
- the nipple 5 is installed in the pipe string below the piston 3 and above the lower locknut 6.
- This ni ple 5 has a conical seat 16, as seen in figure 6, where the piston 3 is supported when the check valve with inertial mass is closed.
- the design of the piston contemplates the sufficient weight to manage to lower and overcome the friction that occurs between the internal gasket 17 and the rod 2. In this way it is guaranteed that the piston 3 is introduced in the nipple 5 and seals the fluid passage inside and outside, as seen in figure 8. Additionally, the design of the piston 3 contemplates diameter 1 (D1) and diameter 2 (D2), as seen in figure 4. Diameter D1 has a sufficient measure for the rod 2 to pass through the piston 3, with a sliding adjustment. The diameter D2 is larger than the diameter D1 in order to provide a loose fit between the rod 2 and the piston 3. This ensures the operation of the system even when the rod 2 has a slight buckling.
