.ALBERT OTTO, OF K'ANSAS CITY, MISSOURI REAMER FOR OIL AND GAS BEARING SAND.
Application filed February 9, 1918.
To all whom t may concern:
Be, it known that I, ALBERT O'r'ro, a citizen of the United States, and-a resident of Kansas City, in the county of Jackson and State of Missouri, have invented a new 'and Improved Beamer for Oil and Gas Bearing Sand, of which the following is a full, clear, and exact description.
This invention relates to appllances for oil wells and has for an object the provision of an improved construction for removing part of the gas and oil `bearing sandstone ot' an oil well so as to allow a freer flow of oil and gas.
Another object in view is to .provide a reaming device for oil wells furnished with a centrifugal reaming structure, and means for removing the removed sand and deposit.
In the accompanying drawing:
Figure l is a longitudinal vertical section through the upper part of the reaming structure disclosing certain features of the invention.
Fig. 2 is a side view with certain parts in section of the lower partof the reaming structure.
Fig. 3 is a sectional view through Fig. 2 on line 3-3.
Fig. 4 is a transverse sectional view through Fig. 2 on line 4 4. V
Referring to the accompanying drawing by numerals, 1 indicates a supporting frame which carries bearing or pivot Iblocks 2 and 3 of any suitable structure coacting with the blocks -l and 5 so as to retain suitable anti-friction balls in place and to rotatably support the casing 6. Arranged interiorly of the casing 6 is a tube 7 having a keyway 8 accommodating the key 9 which key eX- tends through a suitable slot in the casing and is connected to the hub of the drivingv gear 10. Gear 10 meshes with a pinion 11 which pinion is driven by any suitable power whereby the casing 6 and tube 7 are rotated so as to rotate the boring or reaming device hereinafter fully described.
The upper part of the tube 7 is provided with threads 12 accommodating the threaded hand wheel 13, which is used for raising or lowering the tube 7 without disturbing the casing 6, so as to raise or lower the reamer as occasion may demand and as the reamer operates for providing the desired reservoir at the bottom of the well. A pipe 14 extends through the upper part of the Specmoation of Letters Patent. Ptentgd NOV, )19, 11918,
Serial No. 216,293.
tube 7 which upper part is provided with a suita'ble cap 15 'whereby water or other cleaning fluid may fbe introduced into tube 7 and finally discharged through the nozzle pipe. 16 (Fig. 3) at the Ibottom of the well. rlhis water flows downwardly to the bottom of the well and then upwardly carrying with it the removed sand and deposit which has been dislodged by the cutting members 17 and 18 of the reamer 19.
In oil wells it has been found that after continued use for a time there will be accumulated a deposit of parafin or other more or less solid substance at the point where the crude oil and gas enter the well. As this deposit increases the openings through which the oil and gas flow are gradually closed so that some means must be provided for removing this deposit or again providing openings in the sand surrounding the well. Sometimes this has been done by an explosion which is commonly known as shooting the. well, while other devices have been provided for melting or using some force for removing the deposit. Shooting of the well will cure that defect for some time, but it is not unusual that such a procedure will lruin the well. In the present invention it is aimed to secure the same results aimed to be secured by the device above mentioned and othersl which are well known, namely, to remove the deposit and provide a more ready How of the gas and, oil into the well. When it has been found that al given well is flowing slowly, or hasv ceased to How the reamer 19 is lowered into the well to a point opposite the oil and gas bearing sand after which the power or driving pinion 11 is operated ttor rotating the tube. 7 to which the reamer 19 is connected whereupon said reamer will begin to ream or grind the side walls of the wel] for removing the deposit and also some of the sand. Reamer 19 is provided with a head 20 having a passageway theretl'irough which registers with the passageway of the pipe 16 so that the water from the tube 7 may freely enter pipe 16, Head 20 is provided with a threaded eX- tension 21 which is screwed into the lower end of the tube 7 as shown in Fig. 2, and if desired is locked in position by a suitable locknut 22. The head 20 is also provided with cut away portions 23 and 24 having apertures through which the pins 25 and 26 extend, said pins also extending through the respective ears 27 of the reaming or grinding -removed sand and deposit in a loose condi tion and Which will force same upwardly through the well easing 28. lIn order to' assist the upward movement of the water, sand and deposit the tube 7 is provided with a screw 29 which preferably extends from near the reamer as shown in Fig. 2 to the upper end ofthe casing 28,.4 As the reainer is raised and lowered the screw will, of
course, be raised and lowered, but will be substantially in `the same position, as the up and down movement of the reamer is,
merely to cause the same to act on the oil, bearing sand from the upper surface thereof to the lower surface. In this Way there is provided a large reservoir for the accumulation of oil in the Well and in addition a free passage is provided for the oil and gas so that the life ofthe well is renewed without the `usual danger of the well which goes with the process of shooting, or which goes with some of the other processes now in use.
The members 17, 7', 18 and 18 are loosely pivotall'yv mounted on head 20and Will consequently operate under the action of centrifugal fforce when the tube 7 is'rotated. Four of these driving members are shown, but it is evident that one or more may be vused Withoutl departing from the spirit of the invention.
What jI claim is:
A reamer for oil wells comprising a centrifugallyfoperated reamin structurel provided with a head, a plura ity of pivotally mounted reaming members, and a Water nozzle extending from the bottom art of the head, a tubeconnected with sald head for, supplying water thereto andfor supporting the reamer structure opposite `the oil .bearing'sands of the well, means vfor f supplying water to said tube, and means Vfor rotatingl said tube for causing said ream'er to act against the walls of said oil bear,- ing sand for removing some of said sand and thev deposit thereon, f e t ALBERT oTfro,
