Well tool actuator and isolation valve for use in drilling operations |
摘要 |
A well tool actuator can include a series of chambers which, when opened in succession, cause the well tool to be alternately actuated. A method of operating a well tool actuator can include manipulating an object in a wellbore; a sensor of the actuator detecting the object manipulation; and the actuator actuating in response to the sensor detecting the object manipulation. A drilling isolation valve can comprise an actuator including a series of chambers which, when opened in succession, cause the isolation valve to be alternately opened and closed. A method of operating a drilling isolation valve can include manipulating an object in a wellbore, a sensor of the drilling isolation valve detecting the object manipulation, and the drilling isolation valve operating between open and closed configurations in response to the sensor detecting the object manipulation. |
