claims. (ci. 10a-179) 1 This invention relates to an oil well pump, and particularly to a pump capable of ejecting low gravity or heavy oil from a well, and also a pump which is efficient in its operation and can, therefore, effectively and economically pump wells which have a small oil output.
An object of my invention is to provide a novel oil well pump which is simple in construction, inexpensive to manufacture, and which requires little machine work on the barrel or on the pistons.
Still another object of my invention is to provide a novel oil well pump assembly in which the oil is withdrawn from the upper portion of the perforated liner, thereby reducing the possibility of thepump sanding up or becoming gas bound.
A feature of my invention lresides in the novel arrangement and positioning of a packer below the pump, and this packer resting on top of the perforated liner and sealing off the top of this liner so that oil or other liquids cannot drop back into the top of the liner. n
A further feature of my invention is to provide a novel oil well pump con-.struction in which the pistons are formed with flexible packing thereon to engage the wall of the barrel, and a novel upper valve assembly in the pump through which the sucker rods extend.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description andv the appended claims.
In the drawing:
Figure 1 is a fragmentary longitudinal sectional view of the lower portion of my oil well pump assembly.
Figure 2 is a fragmentary longitudinal sectional view of the upper portion of my oil well pump assembly.
Figure 3 is a sectional view taken on line 3-3 of Figure 1.
Figure 4 is a sectional view taken on line 4-4 of Figure 3.
Figure 5 is a fragmentary longitudinal sectional view of the sucker rod coupling.
Figure S is a sectional View taken on line 6-6 ofFigure 1.
Figure 'lA is a sectional view taken on line 'I-1 of Figure 6.
.. Figure 10 is a side elevation of the oil draining device with yparts brokenaway to show inte.-
rior construction.
Referring more particularly to the drawing, the numeral I indicates the usual casing in the well, which extends from top to bottom of the well. The usual perforated liner is indicated at 2, and this liner is positioned within the oil sand and is cemented to the casing I, as shown at 3, all of which is usual and well known in the art.
My pump consists of an elongated barrel 4 on the upper end of which I provide a reducing sub. This sub 5 is threaded on to the `barrel and the purpose of this' sub is to provide an attachment for the tubing 6, which screws on to 0r into the sub and the tubing is of smaller diameter than the barrel il. The tubing 6 extends to the surface and oil is withdrawn from the well through this tubing, all of which is usual and well known.
A reducing fitting l screws on to the lower end of the barrel 4, and a nipple 8 screws on to the fitting l and into the sleeve 9 of the packer I0. An intake pipe II screws into the bottom of the sleeve 9 and extends downwardly into the liner 2. The upper end of the intake pipe II is perforated, as shown at I2, and oil is drawn through these perforatons from the upper part of the liner 2, substantially as shown in Figure 1. The lower part I3 of the pipe I I may consist of a settling basin for the purpose of accumulating sand.
The packer I0 surrounds the pipe II, as previously described, and normally is somewhat smaller in outside diameter than the inside of the casing I. The packer I0 rests on top of the liner 2, as shown in Figure 1, and weight of the pump assembly and tubing will compress the packer I0, causing the peripheral packing I4 to expand and seal the space above the top or open end of the liner 2, thus preventing any liquid from owing back into the top of the liner. Any liquid which might seep into the casing I from upper levels is thus prevented from flowing back into the top of the liner 2. A standing valve I5 is seated in the fitting 'I and performs the usual function of a standing valve in a pump.
The upper Valve assembly and packing I6 consists of a shell Il' which screws into the sub 5, or is otherwise iXedly mounted in this sub. A plurality of oil ports I8 are arranged adjacent the periphery of the shell Il and each port is controlled by a ball valve I9, which seats in the port. A packing gland 20 surrounds the sucker rod 2| and prevents leakage of oil around the sucker rod and back into the pump. The
A plurality of oil ducts 24 extend vertically through each of the pistons 22 and each duct is controlled by a ball valve 25. The sucker rods 2l are secured to each of the pistons 22 and a nut 26 screws on to the lower end of the sucker rod, and this nut is provided with a slot 2l which can engage the bumper bar 28 for the purpose of unscrewing the sucker rods from the piston when desired. A sucker rod coupling 29, of usual and well known construction, is provided above the valve assembly I6 so that the entire pump can be assembled iirst and then attached to the sucker rods at the time it is lowered into the oil well.
Just above the pump, I may provide a iluid drain for the tubing E and included as a part of the tubing, which consists of a sleeve 30, extending oVer the riser 3l. The riser is threaded into the tubing 6, as shown. An elongated slot 32 in the riser is normally covered by the sleeve 30, and consequently oil cannot leak out of this. slot, however, if the tubing 6 is pulled upwardly at the surface, the slot 32 will be uncovered and oil can then drain back. into the casing l so that there is no fluid in the tubing when this tubing is removed from the well. The sleeve 30 is threaded on to the upper porn tion of the tubing S, 'as shown in Figure 2.
Reciprocation of the sucker rods 2t from the surface of the well will move the pistons 22 in the barrel d. On` the up-stroke of the pistons the ball valves 25 are seated and oil is drawn from the formation past the standing valve I5. Also, any oil above the pistons 22 on the up-stroke will be forced past the check valvesv I9 and thence upwardly into the tubing 6, and thence to the surface. On the down-stroke of the pistons 22, the standing valve i is closed, the valves 25 are open and oil passes through the ducts 24 to the space above the pistons 22, and within the barrel 4.
Having described my invention, I claim:
