PLASTIC DRILL PIPES AND SUCKER RODS FOR OIL WELLS Filed Feb. 9, 1959 INVENTOR, /Ww ,Q ia/4W United States Patent O 3,212,582 PLASTIC DRILL PIPES AND SUC'KER RODS FOR OIL WELLS Kenard D. Brown, Fort Collins, Colo. (1227 S. Willow St., Casper, Wyo.) Filed Feb. 9, 1959, Ser. No. 792,143 7 Claims. (Cl. 166-242) This invention relates to an improved sucker rod and tubing structure for oil wells, more particularly for use on wells being pumped by a standard rig employing a pumping jack on the surface which acts to vertically reciprocate a sucker rod for actuating a subsurface pump to elevate the oil within a string of tubing surrounding the sucker rod.
In pumping high paraffin base oils with this type of standard equipment, the paraffin rapidly collects and builds upon both the sucker rod and the tubing so to quickly reduce the output of the well. When this occurs, the sucker rod and the tubing must be withdrawn and disjointed to remove the paraffin deposits. This is an expensive and time consuming procedure.
The principal object of this invention is to provide a sucker rod and tubing structure of a type which will prevent the depositing and accumulation of paraffin and to provide a sucker rod and tubing structure which will allow the sucker rod and the tubing to be withdrawn from the well in a continuous length so as to completely eliminate the expensive, time consuming jointing and disjointing of the conventional sectional sucker rod and tubing.
It has been found that paraffin has an affinity for metal parts. It will rapidly and rmly attach to and build up upon all exposed metal surfaces submerged in the oil in the well. Experiment has shown, however, that paraflin will freely flow over synthetic plastic surfaces without attachment or accumulation. This improved sucker rod and tubing structure completely eliminates all exposed metallic surfaces for the accumulation of parafiin by forming both the sucker rod and the tubing from metal reinforced, flexible plastic so constructed that the metal parts are completely insulated from the oil by the plastic and so constructed that the tubing and the rod will be continuous, flexible units throughout their entire lengths so that they can be withdrawn from the well -as units without disjointing and so that both may be reeled upon a reel as they are withdrawn for cleaning, replacements, and repairs.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and eiciency. These will become more apparent from the following description.
In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
FIG. 1 is a side view of one extremity of the improved tubing and sucker rod, the wall layers thereof being broken away in succession to show the internal construction;
FIG. 2 is a cross section through the sucker rod and tubing structure of FIG. l;
FIG. 3 is a similar successively broken away side view of an alternate form of the improved sucker rod and tubing structure; and
FIG. 4 is a cross section through the alternate form of FIG. 3.
The sucker rod of the preferred form comprises a plurality of relatively straight, longitudinally extending, spaced, exible steel rod wires completely embedded ICC in a cylindrical, plastic rod 11. The tubing of the preferred form comprises an annular plurality of similar relatively straight steel tension wires 12 embedded in a tubular, plastic, cylinder between an outer plastic shell 13 and an inner, separating layer of plastic 14. The inner, separating layer of plastic 14 surrounds a tubular helically wound core wire 15 which in turn surrounds an inner tubular plastic lining 16.
For the purpose of illustrating the wall structure of the tubing the latter has been illustrated in FIG. 1 as being cut away successively at increasing depths. It could be formed by wrapping the helical core wire 15 about the tubular plastic lining 16 thence placing the layer 14 thereover as a continuous tube, thence placing the tension wires 12 along the latter tube and covering them with the outer shell 13. For quantity production, however, the entire structure could be extruded simultaneously about the wires so that a unitary tubular plastic cylinder would include and enclose the inner helical core wire 15 and the outer tension wires 12. The tubing structure could be extruded from the plastic die simultaneously with the wires 10 and the plastic covering 11 of the sucker rod so that the tubing and the rod could be formed simultaneously.
In use, the above described tubing structure is run into the well as a continuous unit and the above described sucker rod, connected to the pump, is similarly, either individually or simultaneously, run into the well as a continuous full length unit. The pumping is accomplished as usual, by applying tension to the sucker rod through the medium of a pumping jack with the oil flowing upwardly between the plastic surface of the sucker rod and the plastic lining of the tubing. It will be noted that no metal is exposed to the oil so that the accumulation of paraffin is substantially eliminated.
It will also be noted that since both the tubing and the sucker rod are formed in continuous, unitary, exible lengths, both can be unreeled from a reel at the surface as they are run into the well and re-reeled so as to eliminate all jointing and disjointing steps. p
The form of FIGS. 3 and 4 is similar to that previously described. However, in the second form, tension wires 17, exposed on the exterior of the tubing, are wrapped about a plastic separating cylinder 18 in a continuous spiral. The tubing 18 contains a spiral core wire wrapping 19, similar to the wrapping 15 previously described, and a lining tube 20, similar to the tube 16 previously described. The sucker rod of the second form, indicated at 21, is a cylindrical, plastic rod containing longitudinally extending reinforcing wires 22 similar to the elements 10 and 11 previously described. The advantages, the functions, and the use of the second form is similar to that of the previously described form.
Sucker rods are exposed to tensional strains due to the weight of the oil and the rod itself. They are also exposed to bending stresses and wall friction due to misalignment of the well. This improved sucker rod is ideally suited to meet these conditions since the straight wires 10 easily absorb the tension and, due to their individually small diameters, they absorb the bending stresses with much less effort than a solid rod. The oil lubricated plastic surfaces of the rod and tubing have a relatively low coetiicient of friction so that ease of operation with minimum wear results.
It can be seen that the improved rod and tubing structure will greatly increase the efiiciency of pumping, in that paraffin shut-downs are greatly reduced if not completely eliminated; full ow is maintained; and the time and labor of pulling is reduced to a minimum.
The core wires 15 and 19 have been illustrated as a single wire wound in spaced-apart turns. It could, of
course, be a plurality of wires wound simultaneously in side by side relation and the spacing could vary in accordance with the particular pressures and conditions which the tubing is designed to accommodate.
The tension wires 12 have been illustrated as straight and the tension wires 17 are positioned at an incline to the axis. These tension wires could, of course, be positioned at any desired incline intermediate the positions shown in FIG. 1 and FIG. 3 depending upon the service for which the tubing is being designed.
The plastic used in the sticker rod and tubing may be any suitable type such as the alkyd resin plastics, commonly known as the polyethylenes or the vinyl plastics, commonly known as vinylidene chloride plastic.
While a specific form of the improvement has been described and illustrated herein, it is to be understood that the same may be varied within the scope of the appended claims, without departing from the spirit of the invention.
