1, within and without the pipe, has been
broken and loosened up, water or other fluid
pressure may be forced down pipe 3 to drive
the matter out between the pipe 3 and pipe
5 1, and air may be used through pipe 5 to
assist this operation. When the paraffin and
other substances have all been cleaned out of
the well, the strata from one well to another
may be blown out with hot steam and air.
10 The upper end of pipe 1 may be sufficiently
closed while the strata to adjacent wells are
being loosened. A plug 4 may be used when
the strata between different wells are to be
blown. This plug 4 is perforated for the
15 passage of pipes 3, 5, and 7. The plug 4
may also be used to confine the heat of the
steam within casing 1 while the paraffin or
other substance is being loosened. Chemi-
cals may be used with the steam for the pur-
20 pose of breaking up the paraffin, or asphalt,
or the chemicals may be used without the
steam.
Should the pipe 3 become clogged in and
about the bottom thereof, a pipe 7 may be
25 used to. force steam or compressed air down
about the pump barrel or lower part of
pipe 3. When the pump barrel is being
used in connection with the working barrel
3, an additional small pipe 7 may be let
30 down in the line casing 1 between the bar-
rel of pipe 3 and the pipe 1. As this pipe
7 is let down within pipe 1 and outside of
pipe 3 hot steam is run down the pipe 7 to
heat the pipe 3 and the pump barrel which
35 is a continuation of the pipe 3. This will
melt the paraffin inside of pipe 3 and within
the casing 1. While the pump barrel is at
work in connection with pipe 3, the water
and oil at the bottom of pipe 3 will be heated
40 and as the hot oil and water rises in pipe 3,
this pipe 3 will be completely cleaned out.
Thus the pipe 3 can be cleaned out without
removing the pipe 3 from the casing 1. Hot
steam is discharged from pipe 7 as this pipe
45 is gradually let down in pipe 1. This will
heat pipe 3 and aid in loosening any paraffin
or asphalt that may be clinging to the in-
side of pipe 3, and when -the hot water and
oil rise or are raised from the bottom of pipe
50 3 up through this pipe 3, the paraffin or as-
phalt will be carried on out of the well.
Provision is also made for introducing hot
steam or other cleansing element down with-in the pipe 3 and the lower end thereof
which constitutes the pump barrel. A pipe 55
8 is run down within the pipe 3 when this
pipe is being used as a pump line, -the pipe 8
being let down by the side of the pump rod
9. Hot steam or other cleansing -fluid is
forced down the pipe 8 to remove any par- 60
affin or other matter that may be accumu-
lated about the pump rod and valves and on
the inside of pipe 3. The pipe 8 may be fit-
ted with a smooth taper nozzle 10 to pre-
vent the injury of the pump rod or valve 65
while being placed in or removed from the
pipe 3 and also to give greater force to the
steam that is put into pipe 3. When the
pipe 3 is used for cleaning purposes during
the clearing of the casing 1 the pump rod 9 70
and the valves may be removed from the
pipe 3.
In case there should be abnormal heat in
the oil well sufficient to cause a crystalliza-
tion of hydrocarbon elements into carbon, 75
it is apparent that cold air can be forced
down in the well to regulate the heat and
any of the pipes above described can be used
for this purpose.
What I claim, is,- 80
1. In an apparatus for cleaning wells, the
combination with a line casing having per-
forations in the side near the bottom end
thereof, of an interior pipe centrally posi-
tioned in said casing and vertically movable 85
therein for forcing hot cleaning fluids down-
wardly and out through said perforations,
and a pipe extending down -between the
walls of said pipes and having the end bent
and extended upwardly for supplying a lift- 90
ing element under a column of fluid to be
drawn out of the well.
2. In an apparatus for cleaning wells, the
combination with a line casing having per-
forations in the side thereof near the lower 95
end, of a combined cleaning, pipe and work-
ing barrel extending centrally down in said
casing and vertically movable therein,.means
for forcing hot fluids down without said
pipe and within said casing, and means for 100
forcing air down under the liquids to be
drawn out of the well.
In testimony whereof, I set my hand this
1st day of January,- 1916.
