Abstract
Methods and apparatus for utilizing a valve with a pump rotor passage with a downhole production string, the pump rotor being on a rotatable rod with a bobbin moving along the rod between a position for opening the passage to fluid flow, when the bobbin is not seated on a shuttle seat, and a position for closing the passage to fluid flow, when the bobbin is seated on the shuttle seat. The pump rotor and rod are removable through the passage while leaving the pump stator in place upstream of the valve.
Claims12
Equipment for producing oil from a downhole location comprising:
- a valve for inclusion in a production string, the valve between a pump proximate a lower end of the production string and an upper end of the production string;
- and,
- the valve for receiving a rod therethrough, the rod for selective rotation to turn a rotor of the pump;
- wherein during a pump rotor removal operation the rod is passed through the valve such that the pump rotor is removed from the pump, the pump rotor entering the valve at a first end of the valve and leaving the valve at a second and opposite end of the valve.
Oil well equipment for producing oil via a production string, the equipment comprising:
- near a lower end of the production string, a pump including a pump rotor;
- a rod that is rotatable coupled to the pump rotor and extending through an upper end of the production string;
- and,
- the rod passing through a valve between the pump rotor and the upper end of the production string;
- wherein during a pump rotor removal operation the rod is passed through the valve such that the pump rotor is removed from the pump, the pump rotor entering the valve at a first end of the valve and leaving the valve at a second and opposite end of the valve.
