Abstract
A system for pumping fluid from a well has a submersible pump introducible into a well for pumping fluid from the well to ground, submersible motor introducible into the well and connected to the submersible pump for driving the submersible pump, the motor including at least one upper tandem motor mechanically connectable to another motor and electrically connectable to a power source, and at least one additional upper tandem motor, the additional upper tandem motor being mechanically connected with the first mentioned upper tandem motor so as to drive the submersible pump with a mechanical power derived from the first mentioned upper tandem motor and the additional upper tandem motor, and a power supply which independently supplies electrical power to the upper tandem motors.
Claims21
A system for pumping fluid from a well, comprising a submersible pump introducible into a well for pumping fluid from the well to ground;
- submersible motor means introducible into the well and connected to said submersible pump for driving said submersible pump, said motor means including at least one upper tandem motor mechanically connectable to another motor and electrically connectable to a power source;
- and at least one additional upper tandem motor, said additional upper tandem motor being mechanically connected with said first mentioned upper tandem motor so as to drive said submersible pump with a mechanical power derived from said first mentioned upper tandem motor and said additional upper tandem motor;
- and power source means for supplying said upper tandem motors with electrical power independently from one another.
A method of pumping fluid from a well to a ground, comprising introducing of a submersible pump into a well for pumping fluid from the well to ground;
- introducing submersible motor means into the well and connecting to said submersible pump for driving said submersible pump, providing in said motor means at least one upper tandem motor mechanically connectable to another motor and electrically connectable to a power source;
- providing in said motor means at least one additional upper tandem motor mechanically connectable to another motor and electrically connectable to a power source;
- mechanically connecting said additional upper tandem motor with said first mentioned upper tandem motor so as to drive said submersible pump with a mechanical power derived from said first mentioned upper tandem motor and said additional upper tandem motor;
- and supplying said upper tandem motors with electrical power from power source means independently from one another.
A motor unit for driving a submersible pump for pumping fluid from a well, comprising a first upper tandem motor which is mechanically connectable to another motor and electrically connectable to a power source;
- at least one additional upper tandem motor which is mechanically connectable to another motor and electrically connectable to another power source;
- connecting means for mechanically connecting said at least two tandem motors with one another without electrically connecting said at least two tandem motors with one another;
- and means for connecting said at least two tandem motor with power supply means for separately receiving electrical power, so that said at least two upper tandem motors mechanically connected to one another and are supplied with electrical power independently from one another, and one of said upper tandem motors is connectable to a centrifugal pump to drive the latter by mechanical power of said at least two upper tandem motors.
