4 Claims.
This invention rela-tes to improvements in assemblies employed in deep Wells for actuating pumps, bailers, and the like.
Ordinarily, pump rods, known as sucker rods, are used in deep wells in actuating pumping mechanisms. These sucker rods are about 30 1s the fact that all forms of wire off whatever gas pressure might exist around the cable has been evolved.
The present invention is directed to an assembly which can be effectively used in actuating deep well pumps, bailers, etc., in an economical manner and without the necessity of employing a multitude of sucker rods as heretofore. Generally stated, the assembly contemplated by this invention may be said to comprise a polish rod extending through a normal well head assembly, wipers, oil savers, glands, etc., the lower end of said polish rod being connected to a plurality of consecutive sections of Wire cable, said sections being composed of right-hand lay cable and lefthand lay cable sections alternately. These sections are connected by couplings, each coupling including a threaded connector adapted to receive a threaded end of a normal sucker rod. The lowermost section of such cable may therefore be readily connected to a sucker rod extending into the pump or other deep well mechanism which is to be actuated. Whenever desired, a section of sucker rod may be connected into the series of cable sections.
Such an assembly has many advantages. Since the sections of cable are alternately composed of right-hand and left-hand lays, torque which pump-actuating sections of right-hand and left-hand cable coupled together, in combination with a normal pony rod or sucker rod.
Another object of the invention is to disclose and provide an assembly comprising sections of wire cable provided with couplings including threaded connectors adapted for engagement with normal sucker rods.
A still further object oi the invention is to disclose and provide as an article of commerce a length of wire cable for use in actuating deep well pumps and the like, each end of said length of cable being iirmly anchored in a coupling having a threaded end portion.
These and other objects, uses and advantages of the invention will become apparent to those skilled in the art from the following description of exemplary forms in which the invention may be embodied.
In the drawings:
Fig. l is a side elevation, partly diagrammatic, showing a typical assembly.
Fig. 2 is an enlarged side elevation, partly in section, through a coupling and connector between two consecutive cable sections.
Fig. 3 is an enlarged side elevation, partly in section, through a modiiiedv form or" coupling.
Fig. l diagrammatically illustrates a conventional type of installation, it being understood that the precise type of casing head and the precise type and number of pipe strings may vary according to the particular characteristics of the individual well and the practice o individual drilling operators. The arrangement shown in Fig l shows a casing head l5 connected tothe upper end of surface casing or conductor pipe li, a water string i2, casing i3, tubing 55:1. tending downwardly through the tubing ld to a pump it is the improved sucker rod assembly oi this invention, generally indicated by the numeral Such assembly may comprise the upper polish rod il, alternate sections oi' righthand and leitJhand lay cable, such as i8, le, iii', id', etc., and a section o sucker rod 2li connected to the pump rod and plunger (not shown) in the pump barrel. Details ci construction of the pump are not indicated, since they are not a part oi the present invention and the structure and operation are well understood in the art.
r.'he upper end o the polish rod may be con nected through any suitable fitting with a wallsm ing beam or other pumping mechanism for reciprocating the assembly.
By referring to Fig. Z (which illustrates a connection between two adjacent sections o cable) it will be noted that the lower end ofthe righthand lay vcable iii is connected to the upper end of the lett-hand lay cable section lil by means of a coupling and connector. Since each end of a section or cable is similarly anchored in a coun pling, the coupling carried by the lower end o cable section is .illustrative of all of the couplings.
coupling carried by the lower end ci cable section it (as shown in Fig. 2) comprises a cylindrical member 2l provided with an Vaxially dieposed port 22 leading to a recess 230i enlarged section past outwardly aring, inner wall suriaces 2d. The enlarged recess 23 is arranged to receive the splayed `end of cable iE and such splayed end is then firmly held in place within the recess by means of Babbitt metal or other means. ''he body portion linay carry on its outer surface a collar of wear-resisting material` 2li, such collar being preferably spaced roma wrenchflat 2l, also formed in the outer surface of the coupling 2l.
That end of the coupling-2l opposite the port or channell 22 is internally threaded, asindicated at 28, with standard or normal sucker rod threads. It will be understood, therefore, that the cable section I8 can be readily connected to a standard sucker rod. It may also be connected to the standard or usual pony rods, such as the pony rod 30. A pony rod is a miniature, short length of sucker rod, each end thereof being provided with an outwardly extending threaded pin. The pony rod 3G can therefore be readily connected to the upper end of cable section i9 provided with the coupling 2l', whereas the upper end of the pony rod can be readily connected to the coupling 2| carried by cable section I8.
Fig. 2 is therefore illustrative oi a joint between successive sections of cable. Thoserskilled inthe art will readily appreciate that any cable section can be connected to a sucker rod or to a polish rod. As a result, the assembly is an extremely flexible one in that the operator may use as many cable sections as he desires (preferably employing right-hand lay and left-hand lay sections alternately and in equal number within the assembly) or he may introduce polish rods, sucker. rods, or the like, at any desired point. When, for example, the assembly is to be used in a deep well, the lower portions oi which are filled with a corrosive oil or liquid, it may be well to use sucker rods in such lower section and cable sections thereabove, since sucker rods are more resistantto the action ci corrosive liquids than ordinary unclad cable.
The modified form o coupling illustrated in Fig. 3 shows the -end of right-hand lay cable section lil extending into a recessed coupling member'i and babbitted therein. This coupled section. is provided with an internally threaded bore adapted to receive a sub E23 provided with an .externally threaded pin end Eli extending into a portion E5 which is in ernally threaded, the cooperating threads at -l being identical to those employed on normal sucker rods. rlhe sub mem-V ber 35 is. provided with an outwardly extending pin capable of engagement with the internal threads 32 on coupling lbody 3i in which the upper endof the left-hand lay cable section it is anchored. .1t will be noted, thereiore, that an assembly composed of coupling lli and subv body 35" may be either connected to an adjacentlength of cable by means of the `adapter 33 or to a nor mal sucker rod.
Attention is called to the fact that :not only7 does the present assembly give rise to many economies, but it greatly aciltates and expedites the making up or a string. When couplings of the character shownin Fig. 2 are employed, substantially all of. the parts usedarestandard and readily available. Moreover, the couplings are easily replaced when worn. The pins and boxes of the coupling members can be reclaimed and reused, even when a section owire line is damaged -or worn, by disconnecting the coupling member or box from the worn line and replacing it with new line. impossible with regular sucker rods. Furthermore, instead of discarding a complete drilling line, only that section which has kinked, worn or has been damaged need be discarded, and a new section can, be readily inserted, thereby resulting -in a definite saving to the operator. Those skilled in the art will appreciate the many advantages which flow from the .construction hereinabove described.
All changes coming within the scopeof the appended claims-are embraced thereby.
Such reclaiming and reuse isv I claim:
with an internal! wrenh flat assembly may crooked well holes.
