Abstract

A variably operable oil recovery system having a variable motor and reducer in mechanical communication with one another where each shares a common axis of rotation. The reducer receives the drive on a high side where each has the same rotational speed, and the reducer maintains a spooled cable on its low side, which rotates at reduced speed and increased torque. The drive and reducer combination move between a first (forward) mode and a second (reverse) mode to alternatingly release and wind a spooled cable extending between the reducer low side and a below surface reciprocating pump. The system is further characterized by an electronic component combination that can continuously manage operational parameters such as stroke length, stroke speed, and power consumption.

Claims (17)

1. A fluid recovery system, comprising:

a drive member, said drive member configured for variable operation;

a torque variation member, said torque variation member being comprised of:

an input member configured to receive and engage said drive member;

a driver disc, said driver disc configured to move about said input member in eccentric fashion, responding to rotational force applied to said input member by said drive member;

an output component, said output component being configured to rotate about said driver disc and said input component; and

an engagement means located along the periphery of said driver disc such that said engagement means alternatingly engages said output component; and

a pumping means, said pumping means configured in mechanical communication with said torque variation member for actuation by said torque variation member, said pumping means being configured for placement in fluid communication with a subterranean fluid source for conveyance of fluid from said subterranean fluid source to a substantially surface elevation.

2. The fluid recovery system of claim 1 wherein said drive member and said torque variation member being configured for operation in first and second opposing modes whereby, when said drive member and said torque variation member are changed from one of said modes to the other said mode, said drive member and said torque variation member change operational directions.

3. The fluid recovery system of claim 1 further comprising:

a system management means comprising:

a measurement means configured for measuring an amount of pumped fluid; and

a control means configured for controlling operational characteristics of said fluid recovery system.

4. The fluid recovery system of claim 2 further comprising:

a system management means comprising:

a measurement means configured for measuring an amount of pumped fluid; and

a control means configured for controlling operational characteristics of said fluid recovery system.
