Abstract

A down-hole oil pump is driven, via a drive shaft, by a wind turbine. Rotation of the drive shaft may rotate an auger which pumps the oil. Alternatively rotation of the drive shaft may be converted to a reciprocating motion to drive a sucker rod and a reciprocating type pump. Solar panels, the electric power grid and/or a combustion engine may be used to supplement the power produced by the wind turbine to assist in driving the pump.

Description

Green energy oilwell production pump
Background
All oilwells today, which cannot produce naturally, have lift-assist pumping systems which require either electric power-drive or are driven by combustion engines. This invention is designed to lift the oil from the wellbore using wind-power, solar power or a combination of both wind & solar energy. The system also allows for a backup support from either mains power and / or combustion engine power, as detailed below: Wind-power oil extraction pumps are environmentally friendly and produce no carbon footprint. The same is true for solar-powered or solar-powered assisted oil extraction pumps.
Oil is discovered in many areas of the world which are remote and the oil extraction may not be sufficiently commercial to run power lines, etc. It may also be uneconomical to run combustion engine extraction pumps.
In addition, some areas have natural, continuous, prevailing wind-power readily available and I or the ability to produce energy from solar-power.
Using the wind-power system: An omni-directional rotating head at the top of the oil-pump assembly will allow for catching the wind force from any direction. The wind force turns propeller blades, which turns the main shaft and drives the rotating imput shaft. The rotating imput shaft drives an auger-type lifting shaft which will extract the oil from the wellbore into a production line. The rotational speed of the auger is determined by the wind speed and also the gear reduction ratio of the driving gears to the imput shaft. The gear reduction box may be a multiplier gearbox which will allow for maximum rotation / lifting ability, even with calm / slight wind conditions. Multiplier gearboxes allow for additional torque, if required.
An optional system allows for the combined use of wind-power and solar-power to drive the same system and finally, the option of additional electric-power, if available or combustion-engine power may be added to the system.
Statement of Invention
The green energy oilwell production pump comprises of the following as detailed in diagrams 1 # to 5# of the attached pages; 1. A lightweight tower to support the windmill style blades / basic design 2. The same unit but with solar-assist power system 3. The same unit but with combustion-engine assist power system 4. The same unit but with optional sucker-rods instead of the lift-auger 5. Basic design of the omni-rotational crown section
1. Description
The onmi-directional rotating head at the top of the oil-pump assembly will allow for catching the wind force from any direction. The wind force turns propeller blades, which turns the main shaft and drives the rotating shaft. The rotating shaft drives an auger-type lifting shaft which will extract the oil from the wellbore into a production line. The rotational speed of the auger is determined by the wind speed and also the gear reduction ratio of the driving gears. The gear reduction box may be a multiplier gearbox which will allow for maximum rotation / lifting ability, even with calm wind conditions.
An optional system allows for the combined use of wind-power and solar-power to drive the same system and finally, the option of electric-power or combustion-engine power may be added to the system.
The system will lift oil, especially heavy crude, by the rotating auger-shaft which is continuously rotating inside the production tubing of the welibore. The crude is lifted and extracted through the production pipeline to the terminal / tank, etc. In some cases, it may be necessary to use a sucker-rod system to lift the oil. This is achieved by replacing the auger-shaft with a sucker-rod of the desired length and the pump lifts the oil by the conventional swabbing method. The sucker-rod action is powered by the same style production pump and the only difference is in using a concentric drive wheel which will cause the sucker-rod to raise & fall. On the up-stroke, the oil is extracted to the pipeline.
Tower -The tower is a lightweight steel structure of various heights, depending in the weather conditions of the desired location and also the exact position of the tower in raised or lowered terrain. The tower can be weighted down with additional concrete removable weights, if required. The tower is designed for ease of movement between wells by means of a lifting skid, lifting eyes and / or hydraulic activated retractable wheels. The new-style tower will replace all of the heavy-structured oilwell pumps in use today. New style lightweight towers may be moved by forklift, crane and or skid-mounted units may be tail-gate lifted onto winch-trucks for ease of transportation. Associated dead-weights may be handled accordingly.
Tower rotating crown -The rotating crown section at the top of the tower allows the drive-wheels / drive-shaft to rotate in any direction to catch the wind direction. It will be mounted to catch the prevailing wind direction for its intended location but will be self-turning to catch wind force from any direction. The top-mounted rudder is fixed on the crown section and will always turn to face the prevailing wind direction.
Windmill style fan-blades -The fan-blades are designed to catch wind force from the front and also from the rear. Two bladed fans mounted either end of the drive-shaft will ensure to trap even the mildest wind-force to activate the drive-shaft in any direction. Multiple bladed fans are designed to catch the maximum amount of wind force.
Auger shaft -The auger shaft is designed to have an upward lift when rotated in a specified direction and this continuous spiral motion of the auger-shaft will lift the crude oil to the surface and deliver it into the delivery pipeline or a designated open tank system, for later trucking. The speed of the auger rotation is determined by the wind-force and also by the gear-reduction ratio design. The lifting auger-shaft may be conventional steel or preferably high-tensile polyurethane for light weight, long-life and durability.
Sucker rod -The conventional sucker rod system can be utilized using the same wind-solar powered units by simply replacing the auger-shaft system with a sucker-rod assembly. The sucker rod action requires modification of the rotating head drive shaft to a concentric wheel driven design as outlined in Model 4# of the attached drawings. The sucker-rod design also incorporates a swivel between the sucker-rod assembly and the drive imput shaft to allow for rotation of the tower rotating head. Sucker-rods may be conventional steel rods or preferably high-tensile polyurethane for light weight, long-life and durability.
Thrust bearings -Used to bear the weight of the drive imput-shaft and associated downhole tools Stuffing-box -Used for isolation of any wellbore pressure and / or spillage of fluids to the surface. Durable long-lasting polyurethane seals & adjustable packing ensures a good surface seal.
Solar panels & storage battery system -Used to trap solar energy and generate power for when the wind-force conditions are insufficient to drive the pump. Can be adjusted for start-up based on declining RPM of the main imput shaft or to be determined by wind-speed as per an electronic manometer.
Alternative external power-source -Used if grid power is available locally and can be attached to the above system with or without the solar-powered unit. As with the solar-system, the grid power will automatically activate whenever wind-speed is insufficient to drive the pump.
Alternative combustion-engine power-source -Used if attached to the above system with or without the solar-powered or grid-power unit. As with the grid power-system, the combustion-engine power will automatically activate whenever wind-speed is insufficient to drive the pump.
Optional clutch -Optional spring-loaded or hydraulic clutch installed at the main drive-shaft will allow for raising & lowering of the sucker-rods by engaging & dis-engaging drive-sprockets for applications which may require additional force or additional lift / travel.
Green energy oilwell production pump advantages 1. The system is environmentally friendly and has no overhead running costs, apart from regular maintenance.
2. There is no carbon footprint if the system is run solely on wind-power and / or solar energy 3. The system will run efficiently in remote areas which otherwise may prove non-commercial to produce new oil discoveries.
4. The system can be integrated with existing grid-power and combustion engine-power systems 5. The system may be lightweight and designed for ease of transportation to remote areas or is quickly transferable to other wells in a multiple well oilfield.
6. The system will run efficiently for wells of borderline commercial value.
