JOHN A; Ynienns, or LONGBEACH, "o aLIFonNaf Arran-Atrus non nearing oir.. A,
Application filed February rlhis invention relates to heating apparatus, and more particularly to an apparatus lor heating the oil in oil wells to reducethe viscosity of the oil, so that it may be more easilT and eiliciently pumped out oi. the well and inv greater` volume than otherwise. l
@ne of the objects of the invention is to provide an oil well heatingapparatus of the character stated, whereby the entire oil formation of the well may be heated.
Another object is to provide an oil well heating` apparatus by means of which the oil will be heated below the pump and all the wayV up the pump and puinptubing to the top of the wallfso that the oil will be more elizectively heated and its viscosity reduced to a minimum, in order that the pump may oper-y ate more eiiieiently and pump the eil` out of the well in efreater volume than is rpossible v t) v with oth u pumpingl apparatus.
Another object is yto `provide an oil ywell pump and an oil heating,` apparatus combined in one struct-ure so that the sainemay be raised or loweredin the oil lwell as a unit.
A further object is to provide a continuous circulating heating system for heating the oil in oil wells.
"With the above and other objects in view, the invention consists in the novel and usefulk iiovision formation constructionand inter- Y 1 a 7 v relation of parts, members and features, all
as shown in the drawing, hereinafter de-c scribed, and finally pointed out in claims.
ln the drawing:
ligure l is a view partly in elevation and partly in vertical section of my heating apparatus as applied to an oil well and pump;
Figure 2 is a vertical section on an `en lai-ged scale of the lower port-ion of myheating` apparatus as shown in Fig. l;
Figure 3 is a vertical section of the lower portionei a modified form of my invention; Y Figure Ll is an enlarged side view of a portion of my invention showing the holding means for the water circulating pipe; and,
Figure 5 is a plan view of Fig. 4:. n Corresponding parte in all the figures are designated by the same reference characters.
Referringl with particularity to the drawing, I have shown an oil well Wlined with a casing;` C and an ripper casing' section C in which the upper portion of the casing C tele- `opes, there being' per'itorations c in the lower portion oi? the casing' C and a hea'd c detachably fitted on the upper end of the casing section C.

The headcf is providediwitha central threaded opening c2 in ywhich is screwthreaded the upper portion or a pump water jacketL tubelv J which extends downwardly into the casingC, the lower end `o' said tube being` screw seated in the upper endet a screw cou pling` K as at j, which coupling is screwfcon-,yr Y
nected to the upper en'd or a perforated inlet tube I provided ,with `perforations z'. The lower end of said inlet tube is coupled tothe uper end of a. het water heating chamber H bymeans of a screw coupling L, which chamber.y i
restsin the bottom of the well, therebeing a headk h gripped between tlie,`,adjoinin`g ends ofthe inlet tubing'fl and the chamber H, which head separates the tube from the chain-` ber. yQn theylower endo the chamber H is connected a cap 72, by means of a screwcoupling h2. kThe water `jacket tube J includes upper section j which isscrew seated at its lower end in the ,opening offof the head l c and is closed at its'upperend by'a head o A' pump P extends throughthe water jacket tube J. This pump may be of the California oil well pump type, but its shoe S, which is screwseated on the lower end of its rbarrel l, is `)formed witha conical end 8 which seats on ar conical seat 7c in the upper end of the eouplingK. The upper end of ,the pump,
tube 2, whicliis coupled atits lower end to Y ytheupper endet the pump barrel 1` by coupling 3, extends through the head j?, and a stufiingooz: in said head. In the pump barrel l are the usual standing' :valve 4,
plunger (lrarbutt rod 6 and nut 7 connectiup,` said valve and plunger, and working` valve 8 connected to the upper end of said plunger, to kwhich latter valve is connected the lower end of the sucker rod l() whichv eX-y tends throughthe stu'fiingfbox llin the upper end of the` pump tubeZf,v there beingoutlet pipes l2 and 13 leading :trointlie upper end or thepuinp tube. E i y o iriiapparatus iorpraeticinginy invention inclu tanl;r `rl", ,heating n n jacket tube J.l `A steam rsupply pipe l5 leads into the steam operating "lindei' 'mi ofthe pump M and a steam exhaust pipe 1G leads from said cylinder into the upper part ofthe water heating' tank 'll where itis wound into a heating' coil N and itsoutlet end n exten ded out oil the lower part of the tank. The tank T isiilled with water and a water pipe'l leads ves a steam pump M, a, water heatingk cliainberf H, 'and' water therefrom into the water cylinder m of the y is split at 19 and its adjoining ends screw.
seated in a screw coupling 2O welded on the upperside of the head fh. On the lower end ot' the pipe 18 in the chamber H is coupled a perforated outlet cage 21. The pipe 18 is clamped o'n the water jacket tube J by band clamps 22 which engage the tube just above` the joint couplings jNk thereof. A bypass 24 leads from the upper end of the heating chamber H into the lower end ot the hot Water jacket tube J. An outlet pipe 25 leads from the 'upper end of the water jacket J into the top of the water heating tank T. In the modilied form of my invention shown in the pipe 18 leads'into chamber H through the side thereof as at 30.
In operation the oil is pumped out of the well by the pump P through the inlet tube I, couplingK, shoe S, pump barrel 1 and pump tube 2. The water in the tank T is heated by the exhaust steam ot the pump M passing through the coil N. Hot water is pumped by pump M out of said tank through pipe 17 into cylinder m and from said cylinder through pipe 1-8 and cage 21 into the heating chamber H, which heats the oil in the well below the pump P, and from said heating chamber the hot water is conducted through by-pass 24, water jacket tube J and outlet pipe 25 back into the tank T, the water passing through the water jacket tube heating the oil in the pump I) and in the pump tubing 2 all the 'way to the top thereof. The heating of the oil in the well below the pump by the hot water in 'the chamber H and the heating of the oil in the pump and pump tube all the way to the top thereof by the hot water in the jacket tube J reduces-the viscosity of the oil, so that Jthe oil may be pumped more freely and in greater volume from the well than otherwise.
The pump and heatingl apparatus including thepipe 18, chamber H, by-pass 24, and water jacket J, being combined in one structure, maybe raised or lowered in the well as a unit.
Having thus disclosed my invention, I claim and desire to secure by Letters Patent:
