' UNiTED STATES RALPH IVI. JACKSON, 0F LA HABRA, CALIFORNIA.
DEEP-WELL OIL PUMP.
Application filed August 26, 1924. Serial No. 734,246.
To all whom l? may concern.'
Be it known that I, RALPH M. JACKSON, a citizen of the United States, residing at La Habra, in the county of Orange and State of California, have invented a new and useful Deep-l/Vell Oil Pump, of which the following is a specification.
This application is an amendmentto an application filed by me, May 9, 1924, Serial No. 712,136 and including an amendment of May 27, 1924.
My invention relates to reciprocating pumps and more particularly to pumps and pumping means for pumping petroleum oil from deep wells.
The chief objects of my invention are to provide, in combination, a pump piston valve mechanism that will not be affected by gas pressure, and means associated with said mechanism adapted to hold excessive downward oil pressure off of the valve while it is opening and closing, and to provide a pump that may be successfully operated with a cable, instead of using pump rods, and to provide a pump without a standing valve below the piston.
Other objects may hereinafter appear.
In the commonly used pump means for the aforesaid purpose, ball check valves are used in the pump piston and such ball check valves are more or less affected by gas in the oil, which causes irregular pumping action. My invention has a positive, mechanically operated valve for the piston.
In the common type of oil pump the downward pressure, or weight of the oil in the line above the piston is constantly against the piston valve, and since such type of pump depends on the weight of the pump rods to open said valve the valve, due to said pressure, does not operate successfully in wells of great depth. In my invention the piston valve works below a packer, which holds the pressure of oil above, ofi:l of the piston while the cylinder is filling with oil from below.
My invention comprises a packer and packing gland, a pump cylinder and piston and piston valve, a hollow actuating member for said piston which extends through Said packer and gland and has inlet means below said packer and outlet means above said packer, and valve means between said inlet means and outlet means for controlling passage through the said actuatingmeans,
The accompanying drawing clearly illustrates my device in the present preferred construction but it is to be understood that various changes may be made in mechanical details without departing from the scope of the invention as claimed.
The drawing is a section of an upper portion of a pump cylinder and a portion of the lower end of a discharge line, and Shows in operative position the principal work@ ing parts of my device some of which are also in section.
In detail, the structure shown comprises,
a pump piston 1 havin@ seal rinor Grooves A*A-A A and two tseal ring? iii each groove, said piston working in a vertically disposed cylinder 2. valve 3, having its seat 4 in said piston, is secured to rod 5 by nut 6, said rod extending upwardly from said valve through a passage way 7 having ports B-B, and guideway 8 in said piston, and is slidably fitted in said guideway. A lock nut 9, adjustable on said rod, limits the downward and the said valve limits the upward lost motion of said rod in the piston, said rod extends thence upwardly and screws into a hollow extension 10, having ports O O, said extension extending upwardly through a packer 11, and packing gland 12, through a connection 13, into a discharge line 14,` `and thence upwardly to a connection 15, said connection forming a valve chamber 16 having ports D-D and containing a valve 17, having its seat 18, at the upper end of said piston rod extension. A sucker rod 19, screws into the upper end of connection 15. Lock nuts 2O and 21 are provided for the connection 15. The device may be constructed to locate the valve 17 and seat 18 just above ports O-(l.
With this structure the pressure from the column of oil above is held by the packer 11, permittino' the oil to pass upward freely, through the open valve- 3, passage 7 and ports B-B, into the cylinder 2, above the piston 1 when the piston and valvey are thrust downward, and ultimately the cylinder will be filled when the piston has completed the downward stroke. At the beginning of the upward stroke the valve 3 is drawn closed by the upward lost motionof rod 5, sliding in the guideway 8, and when the valve is closed the whole mechanism, valves and piston are drawn upwardly by member 10, which forces the oil upwardly through ports O O, passage E, check valve v11/2 to 21/2 inches in diameter and the discharge lines are of correspondingly small dimensions and for this reason I employ a hollow actuating means for the piston, such A structure by permitting the oil to pass the l packer through the actuating means provides for ank actuating means of larger diameter which is better adapted for the packing means required for this purpose.
Due to the fact that my piston valve does not open against excessive pressure my pump may be actuated with a cable instead of the commonly used pump rods; it is however `equally adapted to the use of rods if so desired.
Due to my piston valve being of positive action it is not affected by gas in the oil nor by gas pressure from below the valve, such as is the case with piston valves of the ball check type.
My pump piston and packer may be drawn with the rods out of the cylinder and oil line, the same as the common type of piston, and from the fact that my pump has no valves in the cylinder below the piston,
as in the common type of pump, the oil will drain from the line through the open cylinder at the bottom when the piston and packer are removed. This is an especial advantage when it is desired to remove the oil line, as it eliminates what is called by oil workers, a wet oil line, or in other words a pump line full of oil to be raised to the surface and removed in sections, which is disagreeable or the workmen and a great waste of oil.
Having thus described* myinvention, I claim,
A pump cylinder, a piston in said cylinder, a positive acting mechanically actuated valve in said piston, a packer and packing gland adjacent the upper end of said cylinder, a hollow actuating means for said piston and valve extending through said packer and gland and slidably litted therein, inlet means in said actuating means below said packer and outlet means above said packer, and valve means between said inlet means and outlet means for controlling passage through the said actuating means.
In testimony whereof I hereunto aiiiX my signature.
RALPH M. JACKSON.
