Appl. No.:

10/289904

Inventors:

Benny J. Williams - Godley TX

Assignee:

Harbison-Fischer Manufacturing Company - Crowley TX

International Classification:

F04B 3900

US Classification:

4175551, 417430, 417547, 417554, 4175552, 166105, 166107, 166109

Abstract:

A downhole pump having a barrel with a reciprocating plunger therein has at least one valve. The valve has a cage, a seat and a ball. The cage has a passageway extending between two ends, with the passage including a ball chamber. The ball chamber is between a perforated member and a stop. The ball is located in the ball chamber between the perforated member and the seat, which abuts the stop. The ball is movable along a raceway. The raceway has ribs with channels therebetween. The raceway skews away from a longitudinal axis of the ball chamber from the seat toward to the perforated member. The raceway can be made of a material that is either harder or softer or the same as the hardness of the inner wall of the ball chamber. In another embodiment, the valve has a throat with a stop for receiving a seat. The ball chamber has portions that are hardened.

Inventors:

Benny J. Williams - Godley TX, US

Assignee:

Harbison-Fischer, Inc. - Crowley TX

International Classification:

F04B047/00

US Classification:

417546, 1661055, 4175552

Abstract:

A reciprocating downhole pump has a gas separator located at its bottom end. The separator forms a chamber that is expanded and contracted when the pump is reciprocated. Expansion and contraction of the chamber occurs by either the plunger reciprocating in the chamber or a piston coupled to the plunger reciprocating in the chamber. The chamber has an orifice therein so that during reciprocation fluid flows in and out of the orifice. The orifice is sized so as to subject the fluid to a pressure drop, wherein gas in the fluid is separated from the liquid.

US Classification:

4175552, 277440, 92223, 29888048

Abstract:

A downhole pump for a well has a barrel and a plunger. The barrel has a passage extending along the length of the barrel, with the passage having an inside diameter. The plunger has an outside diameter and is received by the barrel passage for relative reciprocal movement. One of the barrel or the plunger is equipped with wear rings, with a wear ring at one or at each end. The wear rings are made of a material that is harder than the material of the respective plunger or barrel. The wear rings provide protection from abrasion, particularly in a sandy well.

US Classification:

417430, 417545, 417546, 417552, 4175551, 4175552

Abstract:

A downhole pump has a barrel and a plunger which reciprocate with respect to each other. The plunger has a first portion with a first seal, a second portion and a third portion with a second seal. The second portion is intermediate the first and second portions. A balancing chamber is formed between the plunger second portion and the barrel. The balancing chamber communicates with the plunger interior by way of an opening. A sand snare chamber is provided with respect to the opening so as to prevent sand from contacting the seals in the balancing chamber.

Benny J. Williams - Godley TX, US

Assignee:

Harbison-Fischer, Inc. - Crowley TX

International Classification:

F04B 19/00

US Classification:

417238, 471448, 4715552, 92128, 166 68, 166105

Abstract:

A downhole pumping assembly has a tubing string with plural barrels which are arranged in-line with the tubing. The tubing string has a seating location adjacent to each barrel. A standing valve arrangement, which includes a standing valve and a seating device, is located with the standing valve adjacent to the lower end of one of the barrels. A plunger has a traveling valve that is located for reciprocation within the one barrel. The plunger has a clearance with each of the barrels so as to form a fluid seal. The plunger reciprocates inside the barrel so as to lift fluid to the surface. Over time, the barrel will exhibit wear. Instead of pulling the entire tubing string to replace the barrel, the standing valve and the plunger are relocated to one of the other barrels located in the tubing string and reciprocation is resumed to resume pumping.
