Definitions
- the present invention relates to the field of machinery, arrangements and devices used in the oil industry, and more particularly it refers to a gas extracting and transferring unit for oil wells that allows reducing pressure in the well annulus depending on the well gas contribution, thus increasing the production of fluid from it.
- this gas pumping unit is completely independent from the systems commonly used for oil extraction, such as, for example, AIB (Independent Pumping Unit, for its abbreviation in Spanish) rod pumps, PCP, electro-submersible pumps, “PLUNGER LIFT” type pumps, etc., and in turn, it allows programming the required pressure in the well.
- AIB Independent Pumping Unit
- AIB rod pumps are well known in the oil industry, and are known to allow carrying out mechanical extraction of crude oil from oil wells.
- Rod pumps are commonly used in many oilfields, and depending on the size of the pump, 5 to more than 50 m3 of a mixture of crude oil and water can generally be produced in 24 hours.
- the size of the pump is also determined by the depth and weight of the crude oil to be extracted, wherein a deeper extraction requires more energy to move greater lengths of fluid column.
- a connecting rod-crank mechanism converts the motor rotary motion into a reciprocating vertical movement that moves the pump rod, and produces the typical pitch movement.
- the AIB rod pump allows the extraction of crude oil from wells.
- It is still another object of the present invention to provide a gas pumping unit for oil wells comprising at least one compressor cylinder having at least one gas inlet in connection with the well, at least one gas outlet, one pivoting lower end and a double-acting piston whose drive shaft is connected to a drive motor, which can be an electric, hydraulic or combustion motor, said drive motor being connected to a pressure transmitter operatively connected to a pressure switch which is in turn operatively connected to the well.
- FIG. 1 shows an exemplary schematic view of the gas pumping unit for oil wells according to the present invention, wherein it has been illustrated, merely by way of example, in connection with the corresponding parts installed in the well.
- FIG. 2 shows a perspective view of the gas pumping unit for oil wells according to the present invention.
- FIGS. 3 and 4 show a sectional view of the gas pumping unit according to the present invention, wherein the direction of advancement of the piston can be observed allowing gas entry and simultaneous compression/discharge thereof.
- FIG. 1 illustrates the pumping unit in connection with the respective parts of the well.
- both the separation distances and the dimensions of the illustrated components have been illustrated disproportionately, it being understood that this is not a limitation for the invention and that in practice it correctly adapts to the demands of the place.
- the pumping unit for oil wells of the present invention is indicated by the general reference 1 and comprises at least one compressor cylinder 2 having an upper part 3 on which an upper sealing cover 4 is mounted and a lower part 5 on which a lower sealing cover 6 is mounted, both covers 4 and 6 being fixed to the cylinder 2 by respective bolts, pins or similar fixing elements.
- said compressor cylinder 2 comprises an upper gas cylinder inlet/outlet mouth 7 provided in the upper part 3 and a lower gas cylinder inlet/outlet mouth 8 provided in the lower part 5 .
- the compressor cylinder 2 comprises a double-acting piston 9 whose drive shaft 10 passes through the upper cover 4 and has a proximal end that has a connection element 11 provided with a bearing 12 on which a connecting shaft 13 is fixed, said connecting shaft 13 allowing the connection between said driving shaft 10 and a respective connecting rod 14 which is connected to a drive motor 15 -reducer 16 by means of the shaft 17 of the latter.
- the drive motor 10 may be a combustion, hydraulic or electric drive motor, but it is preferably an electric motor which is operatively connected to a pressure switch 18 by a pressure transmitter 41 which is used to control the speed of said motor-reducer, the pressure switch 18 being used to set or establish the start/stop pressure and being operatively connected to the well, more particularly to the annulus space between the casing and the extraction pipe.
- the pressure in the well can be programmable without any inconvenience, this not being possible by any of the conventional devices of the prior art since they operate with the beam pump stroke and there is no way of being able to program the pressure required in the well.
- the pressure transmitter 41 measures the pressure in the annulus and regulates the rotational revolution of the motor so that the piston moves at a greater or lower speed inside the compressor cylinder. This allows the extraction of gas in accordance with gas pressure existing inside the annulus.
- the pressure transmitter 41 sends a signal to the variable speed drive of the motor so that it rotates at higher revolutions and thus generating a greater speed in the piston movement, consequently extracting a greater amount of gas from the annulus in order to reduce the pressure existing in it.
- the use of the pressure transmitter makes it possible to know the pressure in the annulus and to maintain the ideal pressure therein on a constant basis. In turn, owing to the pressure switch arrangement and the pressure transmitter, the required pressure inside the well can be programmable according to the operating conditions of the moment.
- the connecting rod 14 provides an eccentric movement rectilinear to the drive shaft 10 of the piston 9 which moves longitudinally inside the compressor cylinder 2 to allow the entry of gas as well as, simultaneously, its compression and discharge.
- said driving shaft 10 performs a rectilinear eccentric movement, it causes the compressor cylinder 2 to pivot in a tilting manner.
- a pivoting lower end is provided which comprises a lower arm 19 provided with a bearing 20 through which a shaft 21 passes whose ends are fixed to respective lateral support plates (not shown) provided with bearings (not shown) and which are mounted on a frame (not shown) that supports the general structure of the unit of the invention. In this way, pivoting from the lower end is allowed accompanying the eccentric rectilinear movement of the drive shaft 10 and the tilting movement of the cylinder 2 .
- the invention comprises at least one main gas inlet 22 in connection with the well annulus and at least one main gas outlet 23 in connection with the gas production line and/or related reservoirs.
- main gas inlet 22 is on the right, while the main gas outlet is on the left, this does not imply that the invention is limited to said configuration, but other arrangements can be considered and used without any inconvenience.
- the main gas inlet 22 bifurcates and projects into a lower gas inlet 24 which is in connection with the lower gas cylinder inlet/outlet 8 of the lower part 5 of the cylinder 2 through a unidirectional check valve 25 , and in a upper gas inlet 26 which is connected to the upper gas cylinder inlet/outlet 7 of the upper part 3 of the compressor cylinder 2 by another unidirectional check valve 27 .
- the present invention has a lower gas outlet 28 which is connected to the lower gas cylinder inlet/outlet 8 by a unidirectional check valve 29 and an upper gas outlet 30 which is connected to the upper gas cylinder inlet/outlet 7 through another unidirectional check valve 31 , both gas outlets 28 and 30 extending and being connected to the main gas outlet 23 .
- projections and bifurcations mentioned above include tubes or pipes 32 as well as bends 33 , shut-off valves, connectors, flanges, seals, stuffing boxes, etc., as best illustrated in FIGS. 1 to 4 .
- the main gas inlet 22 and the main gas outlet 23 have connectors 34 and are connected to the well and reservoir/production line respectively by means of a conduit 40 or conduits such as duct(s), pipe(s), hose(s) or the like. More particularly, and in accordance with FIG.
- the main gas inlet 22 is in connection with a suction gas outlet 35 from which the gas of the well annulus comes, while said main outlet of gas 23 is in connection with a discharge gas inlet 36 which is projected towards the gas production line and/or related reservoirs.
- FIG. 1 some components of those parts that are usually used in wells have been illustrated for exemplary and helping purposes for a better understanding of the present invention. Wherein, said components that are illustrated are the “casing” 37 , pipe 38 and rod 39 among many others.
- FIG. 4 when the piston 9 moves down, the gas entering through the main gas inlet 22 is projected entering the cylinder 2 through the upper gas inlet 26 —upper gas cylinder inlet/outlet 7 .
- both the direction of gas circulation and the main gas inlet and outlet are not limited to what has been described above, but can be adapted for having other configurations without any inconvenience.
- pressure difference Discharge pressure ⁇ Suction pressure.
- Piston diameter Piston diameter: (psi) 6 inches 8 inches ⁇ P 10 12 14 16 10 12 14 16 5 80 96 112 128 142 170 199 227 10 160 192 224 256 284 341 398 454 15 240 287 335 383 426 511 596 681 20 319 383 447 511 568 681 795 909 DETAILS 25 399 479 559 639 710 852 994 1136 APPLICABLE IN 30 479 575 671 767 852 1022 1193 1363 THE FIELD 35 559 671 783 894 994 1193 1391 1590 40 639 767 894 1022 1136 1363 1590 1817 45 719 862 1006 1150 1278 1533 1789 2044 50 799 958 1118 1278 1420 1704 1988 2272
- the selected well had a production of 02 BO ⁇ 0 BW, in October 2016, taking the following physical measurement:
- the pressure without the compressor or pumping unit was 3 psi, changing to ⁇ 4 (four negative) psi by using the compressor or pumping unit of the present invention, resulting consequently that, that difference of vacuum pressure allows a greater production.
- the pumping unit for oil wells of the present invention is constituted and constructed, which is independent from the operation of the AIB rod pump and in turn, it allows the variation of the piston moving speed to extract a greater or lesser amount of gas in accordance with the existing pressure in the well annulus owing to the novel arrangement of the pressure transmitter and pressure switch. That is to say, the pressure is programmable, this being not possible with any conventional mechanism of the prior art. It is emphasized that the gas extraction cycle is continuous during the period of oil extraction.
- the pumping unit allows maintaining a constant gas pressure in the well, since it has the pressure switch and pressure transmitter that controls the piston speed according to the gas flow to be extracted, pressure being programmable;
- the unit of the invention is environment friendly since it does not generate excessive noise
- Compressor accessories horizontal check valves, bends, tee's, tubes, etc. designed to work in media with gas flow;
- the invention allows varying the piston drive amount according to what we want by means of the variable speed drive that drives the motor and without depending on the frequency of actuation of the mechanical pumping as it occurs with the units of the prior art.
- the unit of the invention allows the compressor to be smaller since there being more frequency a smaller compressor is needed, thus allowing regulating the gas pressure of the well as desired owing to the arrangement of the pressure switch and pressure transmitter connected to the casing that, according to the desired programmed pressure, varies the speed of the motor that drives the compressor and therefore extracts more or less gas.
