This invention relates to a deep Well pump.
An object of the invention is to provide a pump shaped to be located in a well and arranged to be operated by the pressure of balanced columns of an operating uid with means for alternately applying pressure to said columns .of operating uid to effect the reciprocation of the traveling plunger of the pump.
Another object is to provide pump mechanism of this character of such construction that the pressure of the operating fluid will be excluded from the producing stratum in the well.
Another object is to provide pump mechanism lof the character described having a traveling plunger andan operating piston connected to `the plunger and means for coniining balanced columns of operating iiuid in combination with means at the ground surface for applying pressure to one column and simultaneously relieving pressure from the other column inalternating` succession whereby the piston will be reciprocated to reciprocate the traveling plunger of the pump. With the above and other objects in view, the -invention lhas particular relation to certain novel 'features of construction, operation and arrange- -ment of parts, an example oi' which is given in this speciiication and illustrated in the accom-- panying drawings, wherein: Figure 1 shows a vertical sectional view of the Y gupper end of the tubing showing also the means for applying pressure to and relieving pressure 'from the columns of separating iiuid.
Figure 2 shows a side elevation partly in section 'of the pump mechanism, Figure 3 shows an enlargedlvertical sectional 'view of the lower end of said mechanism, and Figure 4 shows an enlarged vertical sectional view of the upper end thereof. In the drawings the numeral Ildesignates a outer tubing 'adapted to be lowered into a well 'and whose lower end may be formed into a screen '2. Within this tubing there is secured a suitable packer 3 preferably located above the liquid level in the well- The numeral 4 designates the inner tubing which extends down into the outer tubing. A suitable tubing head 5' is secured to 'the upper end of the outer tubing and is equipped with a suitable stufling box 6 through which the inner tubing descends. Attachedto the top of the inner tubing there 'is a tubing head 1 and an 'eduction tube 8 is 'iitted through a stuffing box 8 and through the.
head 1 and extends down into the well.
Anchored within and extending beneath the packer 3 there is the cylinder Il having the in- Wardly opening valves II at its lower end and similar inwardly opening valves I2, I2 at its upper end. This cylinder has a head I3 at its upper end to which the lower end of the operating cylinder I4 is connected and the space 5 within the outer tubing and aroundv the inner tubing communicates with the space within said operating cylinder through the joints I5, I5.
Within the cylinder I4 there' is an operating piston I6 and a tubular piston rod Il has its 10 upper end connected to the piston I6 and extends down through suitable stuiling boxes I8, I8 in the cylinder head I3 and its lower end is attached to the traveling plunger I9 ofA the pump. This plunger reciprocates in the cylinder 15 III and is formed with the upper and lower collars 20, 2|, the former of which is controlled by the downwardly opening valves 22 and the latter of which is controlled by` the upwardly opening valves 23, said valves controlling the 20 I inlet of the pumped fluid into the chamber 24 by the pump plunger. The eduction tube 8 is let down into and is closely surrounded by the tubular piston load I1 said eduction tube being anchored to the upper end of the cylinder I4. 25 The upper end of the cylinder I4 has the port 25 for the admission of operating fluid from the inner tube 4 into the cylinder I4 above the piston I6.
At the ground surface, means have been pro` 30 vided for applying pressure to thecolumns of operating fluid. As shown this means for applying pressure to said operating uid comprises the cylinders 26, 26 and leading from the outer end of these respective cylinders are the pressure 35 lines 21, 28, the former entering the outer tubing 4and the latter entering the inner tubing. In the cylinders 26 are the reciprocable pistons 23, 29 which are welded to the ,outer end of the pistn rods 36, 30. The inner ends of these roads are 40 attached to the reciprocable cross heads 3I, 3| which are reciprocated by a suitable central tower. The outer tubing and the pressure line and simultaneously relieved from the other in 55 alternate succession and the piston I6 will be correspondingly reciprocated thus reciprocating the pump plunger I9. The cylinder I will be 'submerged in the liquid tobe pumped and upon upward movement of the pump plunger I9 the liquid will enter through the' valves II into the cylinder III beneath said plunger and the liquid in said cylinder I0 above said plunger will enter the chamber 24 through the ports 20 and pass on into the eduction tube 8. Upon downward movement of the plunger I9 the liquid from the well will flow into the cylinder I0 above the plunger through the valves I2 and the liquid in the cylinder III beneath said plunger will pass in through the ports 20 to the chamber v24 and thence up through the eduction tube 8 and with each downward and upward stroke of the pump plunger I9 the pumped liquid will be discharged through the eduction tube 8.
The drawings and specication now disclose what is considered to be a preferred form of the invention by way of illustration only, while the broad principle of the invention will be defined by the appended claim.
What I claim is:
A deep well pump comprising an outer tubing, a tubular packer within and forming a fluid-tight seal with the wall of said outer tubing, an inner tubing extending down into the outer tubing, said outer tubing having a seal through which the inner tubing extends, a. tubing head attached to the top of the inner tubing, an eduction tube extending through and forming a fluid-tight joint with the tubing head and extended down through the inner tubing, a lower cylinder anchored to and extended beneath said packer, said cylinder having inwardly opening valves at its lower and upper ends and havingan enlarged head upon the upper end of said cylinder, an upper operating cylinder whose lower end is connected to said cylinder head, said operating cylinder having inlet ports at its respective ends, one communieating said upper cylinder with the outer tubing and the other communicating the upper cylinder with the inner tubing, an operating piston within said operating cylinder between said ports, said eduction tube extending through said piston and through the' operating cylinder and terminating in the lower cylinder, a tubular piston rod around the eduction tube and attached, at its upper end, to said piston, said piston rod being extended through and forming a duid-tight joint with said cylinder head, a hollow pump plunger in the lower cylinder to which said piston rod is connected, whereby the piston and plunger are rigidly con-- nected together, inwardly opening upper and lower valves controlling the ow of liquid through said pump plunger into the eduction tube, means for anchoring the eduction tube to the upper end of the operating cylinder, and means for alternately applying uid under pressure through said upper and lower ports to opposite sides of said piston.
