Appl. No.:

6/513948

Inventors:

Thomas A. Gilbertson - Moraga CA

International Classification:

F04B 4708

US Classification:

417401

Abstract:

An oil well pumping unit comprising an oil pump unit and a hydraulic cylinder coupled in driving relation to the pump unit and adapted to be mounted along with the pump unit within a bore hole. The cylinder has top and bottom fluid ports and a cylinder rod operatively driving the pump unit. Hydraulic drive/control means is coupled to one of the fluid ports to provide a hydraulic power stroke of said cylinder rod in one direction. The other of the fluid ports of said cylinder is coupled to the well fluid column above said cylinder or to a closed energy storage system to provide energy for producing a return stroke of the cylinder rod. The oil pump unit includes: an elongated cylindrical pump barrel with a first stationary valve mounted at a bottom end of the pump barrel for controlling the entry of bore hole fluid and a second stationary valve mounted at a top end for controlling the exit of oil from the pump barrel into the well casing above said pumping unit. A packing means is mounted in an intermediate position on the pump barrel for retaining the pump barrel in a position within the well casing and forming a seal between the inner wall of the well casing and the pump barrel to define high and low pressure regions of the well respectively above and below the packing means. A cylinder mounting means is provided for mounting said hydraulic cylinder in a substantially sealed manner on top of the pump barrel with the cylinder rod coaxial with the pump barrel and sized to be received within the pump barrel on a downstroke of the cylinder rod to displace bore hole fluid within the pump barrel through the second valve.

Assignee:

Reaction Thermal Systems, Inc. - Napa CA

International Classification:

F25D 300

US Classification:

62185

Abstract:

A chill water system combining a storage vessel 10, a multiplicity of ice encapsulating units 11 contained in the vessel and a chiller system 60. The storage vessel contains a volume of glycol and water solution having a freezing point of about twenty six degrees F. The ice encapsulating units 11 comprise sealed containers filled with a deionized water and having a volume of powdered cholesterol therein to serve as an ice nucleating agent to lower the initial ice formation temperature of the unit. The containers have imperfect geometric shape and deformable wall structures to permit an increase in enclosed volume as said water therein freezes. Chiller system 60 is operatively associated with the vessel and cools the glycol and water solution to about twenty six degrees to freeze the water in the containers 11. A topping tank 90 and an inventory tank 93 receive liquid from the storage vessel 10 as the ice encapsulating units 11 freeze and expand in volume.

Inventors:

Thomas A. Gilbertson - Moraga CA

International Classification:

F04B 4704

US Classification:

417401

Abstract:

An oil well pump driving unit which includes a hydraulic cylinder mounting arrangement which eliminates the use of a stuffing box by mounting the cylinder by way of a mounting arrangement on top of a pumping tee at the wellhead which includes a cylinder rod sealing arrangement separate from the one in the hydraulic cylinder to preclude leakage of well fluid around the cylinder rod.

US Classification:

62430

Abstract:

A chill water system combining a storage vessel 10, a multiplicity of ice encapsulating units 11 contained in the vessel and a chiller system 60. The vessel contains a volume of glycol and water solution having a freezing point about twenty six degrees F. The ice encapsulating units 11 comprise sealed containers filled with deionized water and having a volume 131 of powdered cholesterol therein to serve as an ice nucleating agent to lower the initial ice formation temperature of the unit. The containers have imperfect geometric deformable wall structures to permit an increase in enclosed volume as said water therein freezes. Chiller system 60 is operatively associated with the vessel and cools the glycol and water solution to about twenty six degrees to freeze the water in the containers 11. A topping tank 90 and an inventory tank 93 receive liquid from the storage vessel 10 as the ice encapsulating units 11 freeze and expand in volume.

Inventors:

Thomas A. Gilbertson - Moraga CA

International Classification:

F04B 4704

US Classification:

417399

Abstract:

An oil well pump driving unit with a horizontally disposed hydraulic cylinder having a cylinder rod coupled to a drive rope extending into a pumping tee-stuffing box arrangement for driving the sucker rod string leading to a conventional oil well reciprocating pump. The drive rope extends over a first rotating sheave mounted near the wellhead and passes over a second rotating sheave mounted on a carriage which traverses a carriage channel in a draw works on which the hydraulic cylinder is mounted. A hydraulic drive/control system utilizing limit switches on the draw works provides control over the stroke position, the stroke length, and the stroke rate.

International Classification:

F04B 4704

US Classification:

166 685

Abstract:

An oil well pumping apparatus which includes a submerged reciprocating pump mounted in a tubing arrangement communicating with the wellhead, a sucker rod string extending through the tubing arrangement and connected in driving relation with the pump, and a pumping tee and stuffing box arrangement mounted on the casing of the well at the wellhead and including a sealed drive rod arrangement in the stuffing box connected in driving relation to said sucker rod string, and a pump driving unit. The pump driving unit includes a hydraulic cylinder and support means including a gimbal arrangement for supporting the hydraulic cylinder over the stuffing box with the axis of the cylinder rod aligned with the axis of said stuffing box. A coupling means is provided for coupling the cylinder rod to the sealed drive rod arrangement. A hydraulic drive/control unit is coupled to said in/out fluid line for operating cycle consisting of a hydraulic power upstroke and a gravity power downstroke.
