Abstract
A method for controlling a stroker actuator, that includes measuring a piston extension length, calculating a piston buckling threshold based on the piston extension length, measuring a piston force, making a determination that the piston force exceeds the piston buckling threshold, and based on the determination, shortening the piston extension length.
Claims20
A method for controlling a stroker actuator in a wellbore, comprising:
- measuring a piston extension length;
- calculating a piston buckling threshold based on the piston extension length;
- measuring a piston force;
- making a determination that the piston force exceeds the piston buckling threshold;
- based on the determination:
- shortening the piston extension length;
- and
- extending a piston, wherein the piston impacts an object while extending,
- wherein prior to the piston impacting the object, the piston is not contacting the object, and wherein when the piston impacts the object, the piston contacts the object.
