BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an elevational view of a well bore and well head in cross section.
FIG. 2 is an enlarged, elevational view of a pressure chamber.
DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawings, the numeral 1 designates a well casing mounted in a well bore and extending from the ground surface 2 to the production formation 3. A collar 4 is mounted on the upper section of the casing l and the well head housing 5 is diametrically reduced at one end and externally threaded to be received by the internal threads of the collar 4. The upper portion of the head housing 5 forms an air storage chamber 6, having the partition 7 separating the storage chamber 6, from the lower chamber 8. An air compressor and motor 9 is mounted in the chamber 8 and has the line 10 leading into the chamber 6. An air discharge line 1 1 leads from the chamber 6 and into the valves 12, 13 which are controlled by the recycling control 14, powered through the supply line 15, leading from a suitable source of power (not shown). A production tubing 16, having a valve 17 and a tester bleed off 18, extends through the housing 5 and extends into the well casing. At spaced intervals in the production tubing and mounted on said tubing are the pressure chambers, as 19, 19, and a back pressure valve, such as the ball and cage 20, are mounted in the production tubing immediately above each pressure chamber. An air passageway 21 is formed in the upper end of each chamber 19 into which one of the respective air lines 22, 23, 24, 25, are mounted. In one of the lines leading from each of the valves 12, 13, is a restricted orifice, as 26, 26, which may be of the adjustable type, to provide means for varied restriction of flow therethrough.
The lower end of the production tubing extends into the screen 27, through the usual packing 28. In each chamber 19, adjacent the lower end thereof, are flow passageways 29 into the production tubing.
In operation, the well is first engineered to determine the rate of flow into the screen area, and the weight of the production. With this information at hand, the operator sets the timing means (not shown) to actuate and deactivate the pump at intervals providing the maximum production, and sets the recycling unit 14 to control the valves 12, 13, to provide a continuous flow of production until the fluid in the screen area is exhausted. The valves 12, 13 pressurize alternate chambers 19, the air flowing into the chamber being pressurized, through the lines 24, 25, forcing the fluid in the chamber through the passageways 29 and up the production tubing, past the back pressure valve 20 into the chamber 19 above, which is being exhausted, the air in the chambers last mentioned escaping through the lines 22, 26. The restricted orifices are in the lines leading to the uppermost chambers, and the delay in raising lifting pressure caused by these restricted orifices, will give the lowermost chambers a chance to have received a supply of pressure and the movement upwardly in each of the pressurized chambers will be at approximately the same time. An adjustment of the orifices may be necessary to tune the operation to a smooth constant flow. Upon lapse of the predetermined time foremptying the pressurized chambers, the recycling unit will reverse the flow of air, pressurizing the now filled compartments and exhausting the ones to be filled.
When the supply of production fluid in the screen area has been depleted, the timing device will deactivate the pump until the necessary time interval to permit the area to again be filled from the formation, when the pump will again be actuated and the pumping process repeated.
While four pressure chambers are shown, it is obvious that as many as are necessary may be employed, with taps off of the respective air lines. The air storage chamber 6 may be provided with the usual gauge to assure maintainance of the necessary supply of pressure to actuate the pump.
The method herein taught consists of engineering a well, determining the rate of flow into the screen area and the weight of the production fluid, adjusting the timing mechanism accordingly, and adjusting the recycling mechanism to move the air from the storage tank into the respective chambers, restricting the flow to the uppermost members to permit a time delay in the actuation of the said last mentioned chambers so that the movement of the production fluid upwardly in the production tubing will be simultaneous, and deactivating the pump when the predetermined time interval has lapsed, to permit refilling of the screen area.
Where gas is present from another strata, or from any other outside source, it may be substituted for the air hereinbefore referred to.
What we claim is:
1. In a pump, a production tubing in a well casing, a plurality of pressure chambers in said tubing at spaced intervals, a source of supply of pressure, pressure lines leading from said source of supply to said pressure chambers, selectively adjustable timing mechanism for actuating the valves controlling the flow of pressure and to pressurize alternate chambers and simultaneously exhaust the other chambers.
2. The device defined in claim 1 having adjustable means in a portion of said pressure lines restricting the flow of pressure therethrough.
3. The device defined in claim 1 wherein each of said pressure chambers have a section of production tubing extending through the longitudinal axis thereof, and have passageways in said production tubing adjacent the lower ends thereof, for the passage of production fluid into and out of said chambers, and back pressure valves in said tubing adjacent the upper end of each of said chambers.
4. The device defined in claim 1, having means for controlling the flow of production fluid from said proto alternate chambers in said tubing and simultaneously exhausting the remaining chambers, reducing the flow of pressure to the uppermost chambers to permit the required pressure build up in the lower chambers.
6. The device defined in claim 1 wherein said source of supply of pressure is gas from another formation than that from which the production fluid is being produced.
