WELL-PUMPING SYSTEM 3 Sheets-Sheet 3 Filed Oct. 15. 1962 FIG. 7.
INVENTORS. CHARLES B. CORLEY, JR., PETER R. McSTRAVICK,
ATTORNEY.
United States Patent This invention relates to the pumping of wells. More particularly, this invention is an improved well-pumping 3 system for simultaneously pumping a multiple completion-type well.
Usually, in pumping a plurality of wells or a multiple completion-type well, one pumping unit complete in itself is used to pump each completion as needed. Hence, if there are, for example, four completions, four complete pumping units are required. Therefore, a method of pumping several completions with only one pumping unit is highly desirable. This would eliminate an obvious duplication of material and expense.
The invention to be described herein uses only one pumping unit. This pumping unit can be used to simultaneously pump a plurality of wells.
Briefly described, the new pumping system includes a single main pumping unit. Means are operated by the pumping unit to move a plurality of pulley drive shafts in back-and-forth rotative movement. A number of pulleys are mounted on the drive shafts, the total number corresponding to the number of wells to be pumped. Means, such as flexible cables, are connected to each pulley and lead to the corresponding completion well for operating a subsurface pump.
The invention, as well as its many advantages, will be further understood by reference to the following detailed description and drawings in which:
FIG. 1 is a plan view showing a part of our new pumping system;
FIG. 2 is a view taken along line 22 of FIG. 1;
FIG. 3 is a view taken along line 3-3 of FIG. 1;
FIG. 4 is an elevational view of a pump for operating the main drive, the main drive being shown along line 4-4 of FIG. 1;
FIG. 5 and FIG. 6 are modifications of the gear mounts of FIG. 1; and
FIG. 7 is a view similar to FIG. 3 showing a modification of the invention.
Referring to the drawings and particularly to FIG. 4, a main pumping unit indicated generally by the numeral 10 is shown supported on support 12 which may be positioned at any desired height above the earths surface. The pumping unit 10 includes a gearbox 14 operated by a source of power (not shown). The power operates a rotatable weight 16 to which a pitman rod 18 is connected. The pitman rod 18 is, in turn, connected to the walking beam 20 having a horsehead 22.
A cable 24 is connected to the horsehead 22 and leads to a main drive pulley 26 rigidly mounted on a main drive shaft 28. Referring to FIG. 1, it can be seen that the main drive shaft 28 has its ends mounted within a generally U-shaped support 30. The main drive pulley 26 is provided on one side thereof with gear teeth 32 (see FIG. 2) adapted to engage bevel gear 34. Gear teeth (not shown) on the other side of main drive pulley 26 are adapted to engage bevel gear 36.
Bevel gear 34 is connected through shaft 38 to a universal and slip joint 40. Universal and slip joint 40 has its other end connected to a shaft 42 mounted within support 44. A second universal and slip joint 46 is also connected to shaft 42 and through shaft 48 to a bevel gear 50 mounted within L-shaped support 52. Back-and- 3,166,944 Patented Jan. 26, 1965 forth rotative movement of main drive pulley 26 causes shaft 42 to be rotated back and forth.
Also, mounted within the L-shaped support 52 is a gear 54 mounted in a manner so as to provide a right-angle drive. In a similar manner, L-shaped supports 56 and 58 provide support for right-angle gear drives 60 and 62, respectively.
Shaft 64 supported by bearing 66 is rotated in backand-forth movement by means of gear 54 and gear 63 through universal and slip joints 70 and 72, respectively. Shaft 74 is rotated in back-and-forth movement by means of gears 78 and 80 through universal and slip joints 82 and 34, respectively. Similarly, shaft 86 is rotated in back-and-forth movement by means of gears 88 and 36 through universal and slip joints 90 and 92, respectively.
At least one pulley is mounted on each of the pulley drive shafts. The actual number of pulleys should preferably correspond to the number of wells to be pumped. For example, in FIG. 1, four wells are shown. Therefore, pulleys 94, 96, 98, and are shown rigidly connected to pulley drive shafts 42, 64, 74, and 86, respectively.
A flexible cable 102 is connected to each of the pulleys. The flexible cables 102 are, in turn, attached to the top of polish rods 104. Each polish rod 104 leads through a wellhead and to the subsurface pump used to pump the well.
As shown in FIG. 3, support 76 is horizontally adjustable for installing various pulley sizes. Horizontal adjustment is made by removing bolts 106, sliding the base of support 76 in groove 108 provided in base 110, and replacing bolts 106.
In operation, the power source operates the rotating weight 16 which causes the horsehead 22 of the pumping unit 10 to move upwardly and downwardly through the operation of pitman rod 18 and walking beam 20. The up-and-down movement of horsehead 22 causes the main drive pulley 26 to be moved in back-and-forth rotative movement. This movement is caused by the connection of cable 24 to the horsehead 22 and the main drive pulley 26. The back-and-forth rotative movement of main drive pulley 26 causes the back-and-forth rotative movement of pulleys 94, 96, 9S, and 100 to operate the pumps in the subsurface wells.
In the embodiment shown in FIG. 1, as the main drive pulley 26 is moved downwardly, all the cables on all the pulleys are also moved downwardly. Conversely, when main drive pulley 26 moves upwardly, all the cables on all the pulleys are moved upwardly. With a less powerful pumping unit, this may create an undesirable load on the pumping unit. Hence, modifications are shown in FIG. 5 and FIG. 6 as substitutes for L-shaped members 58 and 52. As shown in FIG. 5 and FIG. 6, C-shaped members 112 and 114 are substituted for L-shaped members 58 and 52, respectively. Also, outboard gears 116 and 118 are substituted for inboard gears 80 and 54, respectively. With this arrangement, pulleys 94 and 100 are moved downwardly while pulleys 96 and 98 are moved upwardly and vice versa. This tends to reduce the load on the pumping unit.
Stroke variation can also be maintained by using adjustable pulley mounts for up-and-down and horizontal displacement so that various sizes of pulleys can be installed. This modification is shown in FIG. 7. Referring to FIG. 7, the bearing 120 is shown provided with a rigid shaft 122. A pivot arm 124 is connected to the shaft 122 and also to the shaft 126 upon which the pulley 128 is mounted.
A stud 129 is also mounted on the bearing 120. The stud 129 is adapted to fit into each of a plurality of holes 130 provided in an adjusting arm 132. The adjusting arm 132 is also connected to the pulley drive shaft 126.
The provision of the pivot arm 12 5 and adjusting arm 132 with the holes 130 provides for a quick and easy Way of adding diflierent sized pulleys to vary the length of stroke of the pump. The different sized pulleys are shown in broken lines in FIG/7.: The flexible rod cable 134 connected to the pulley 1-28 is :packed of? directly in the wellhead 136 by means'of the stufiing gland 138. The bearing 120 may also be adjusted horizontally by incorporating a base mounting as shown in 'FIG. 3.
We claim:
1. A well-pumping system for simultaneously pumping a multiple completion Well comprising: a pumping unit; a main drive shaft, a single main drive pulley rigidly mounted on the main drive shaft; a cable connected to the pumping unit and the main drive pulley so that the main drive pulley is moved in backand-forth rotative movei merit; a plurality of pulley drive shafts operated by the main drive pulley; supporting means for supporting the plurality of pulley drive shafts; at least one pulley mounted on each pulley drive shaft; and means connected to each pulley and leading to a corresponding completion for operating a subsurface pump.
