'AUTOMATIC OIL AND GAS SEPARATING) PUMP.
Appeati-on filed February 16, 1924. Serial N o. 693,373.
have invented certain new and useful Improvements in Automatic Oil and Gas 'Separating Pumps, of which the following is a s ecification.
ur invention f relates to the class of pumps adapted for use in the production of p petroleum.
Our pump is especially applicable in wells where gas is present, in that it is capable of automatically separating the oil and gas, said separation taking place at the point where the oil enters the pump, the gas being mainly excluded, thus relieving the pumping nstrumentalities of its presence, and resulting in distinct advantages as will hereinafter appear. In entitling and describing our invention in terms of oil and gas we are simply referring, for the sake of illustration, to the petroleum producing art as the one in which the invention is immediately 'and particularly applicable. It must be understood however that our pump may be used in any situation and with any Huid-body aggregate comprising a liquid and a gaseous component under circumstances where it will be of benefit to the pump to exclude the gas therefrom. It will also be understood that changes in the form and arrangement and in the details of our pump may be made without departing from the spirit of the invention as defined in the claims hereunto appended. lVith this understanding we shall now describe our invention in its npreferred and practical embodiment, reference being made to the accompanying drawings in which- Figure 1 is a vertical section of the barrel portion of our pump and its connections; the valve and plunger assembly being omitted.
Fig. 2 is a vertical section, enlarged and broken, of that portion of our pump, which includes the valve and plunger assembly.
Fig. 3 is a vertical section of that portion of the pump in the region in which the separation of the gas takes place, showing the point of entrance of the oil to the annular space within the pump barrel.
Fig. 4 is -a vertical section of that portion of the pump in the region in which the oil from the pump barrel enters the interior of the pump to be directed to the plunger and valve assembly.
1 indicates a well and 2 the casing. 3 1s the pump barrel which at its upper end is connected with the tubing-string 4 leading to the surface, by the coupling 5, Fig. 3. At the lower end the barrel 3 is connected with the tail-pipe 6, by the couping 7, the foot of the tail-pipe being closed,
lig. 4.
Within the pump barrel 3 are the liner members 8, usually as here shown, in a plurality of sections. These liners have an exterior diameter sufficiently smaller than the interior diameter of the barrel 3 to leave an intervening space indicated by 9, and said liners are provided with exterior lugs 10 both circumferentially and linearly spaced, which bearagainst the inner Wall of the barrel. The top liner as seen best. m Fig. 3, has a collar 11 on its upper end, and the bottom liner as seen in Fig. 4, has a collar 11 on its lower end, said collars closely fitting the barrel thus closing thel space 9 above and below, as in Fig. 1. The liners are held in place between the couplings 5 and 7.
The barrel 3 near its upper end has the ports or openings 3', Figs. 1 and 3 through which the well interior communicates with the upper portion of the space 9. The bottom liner has ports o r openings 8', Figs. 1 and 4, through which the space 9 at its lower portion communicates with the interior of the pump assembly and with the tail pipe 6. Referring now` to Fig. 2, 12 is the upper y or traveling-valve assembly, with which is connected the sucker rods 13, above, and the hollow plunger 14 below.
15 is the lower or standing-valve assembly which is seated at 16 in the usual manner in the barrel linings, and has extending downwardly from it the anchor or suction pipe 17. The standing-valve assembly 15 is -connected above with the plunger 14 by means of the usual garbutt rod 18 to enable said assembly to be pulled out with the other Working parts of the pump.
The operation of the device as indicated by the several arrows, is as follows. The gas and liquid rise together in the well. At the upper ports 3 the separation takes place, the gas passing on up in the well as seen in Fig. 3, while the liquid passes through said ports into the space 9. In this space the liquid descends and passes'through the lower ports 8 as seen in Fig. 4 into .the interior of the'pump. lThence down in the tail pipe 6 and up through the anchor or suction pipe 17, F ig. 4, the standing valve assembly 15, the plunger 14:, the traveling'valve assembly 1,2, and the tubing string l to the surface, Figs. 4, 2 and 3. The separation of the gas from the liquid isy due tothe downward course which the liquid is compelled initially to take and occurs at the point where the liquid enters the pump structure. The advantage gained is the assured and positive valve action, thus increasing the pumping eiciency.-
In pumping equipments as usually employed in the production of o-il where gas is present, the valve action is not positive, due
to the fact that the gas drawn through the bottom Valve often collects in the plunger between the valves, thus preventing the Apump from obtaining full capacity of displacement, since the gas will not pass out from the pump through the top lvalve until the pump creates a pressure between the, valves sufiicient to overcome the weight of the liquid .above. n
Moreover, the presence of gas also causes Valve chatter, which is destructive tothe balls and seats )of ball-check valves, and oftentimes necessitates the pulling of the Pump?. operation 1s costly, 1n additlon to wear and tear on equipment, and loss of production. Valve chatter, caused by gas also decreases the yeliiciency of the pump, due to the fact that the valve does not properlyclose during pump action.
.It will also be seen that by the separation of the gas and' oil by means of our pump emulsion is eliminated.
We claim: A
1. An oil and gasseparating pump comprising a closed barrel adapted for suspension in a well; a liner itted concentrically within and spaced from said barrel, the space between. the barrel and liner being closed above and below, said barrel having ports through which the well communicates to renew said balls and seats. This with the upper-portion of said space, and
said liner having ports through which the lower portion of said space communicateswith the interior of the liner; and pumping instrumentalities fitted within saidliner intermediate said. ports.
2. An oil and gas separating pump comprising a barrel adapted for suspension in a well; a tail pipe carried by fthe lower end of the barrel, said tail pipe having a closed foot; a liner fitted wnc'entricalljr within and spaced from said barrel, the space between the barrel and liner being closed above and below, said barrel having ports Athrough prising a barrel adapted for suspension 1n a well, said barrel having an exterior space with an entrance from the well to its upper ortion vand said s ace havin also an en-l. Y
trance from its lower portion into the interior of the barrel; and pumping instrumentalities within the barrel intermediate said entrances.
4:. An oil and gas separating pump comprising a barrel adapted for suspension in a well, said barrelhaving an exterior cir? cumscribing space with closed ends, said space having an entrance in its side to its upper portion from theffwell, and said space having also an 'entrance in its side from its lower portion into the interior of the barrel; and pumping instrumentalities within the barrel intermediate said entrances.
