Control system for a top drive

摘要

A top drive control system with a remote control having a processor and data storage connected to a torque pin sensor, a speed sensor, a remote control, which enables a user to actuate automatic remote rocking, drilling, orienting and making-up of a drill string using the top drive and provides simultaneous right hand and left hand torque applied to the drill string while simultaneously controlling speed of turning of the drill string. The top drive control system includes computer instructions for automated orienting of drill pipe, automated drilling with drill pipe and automated making-up of drill pipe into a drill string.

主权项

1. An automatically executing control system for a top drive for a drilling rig wherein the control system communicates with a hydraulic pump and a prime mover, wherein the control system comprises:
(i) at least one processor; (ii) data storage connected to the at least one processor; (iii) a torque pin sensor connected to the at least one processor and mounted between the top drive and a torque track slide assembly for moving the top drive; and (iv) a speed sensor connected to at least one of the processors and mounted integrally within the top drive; b. a remote control connected to the processor, enabling a user to remotely perform at least one of four modes of operations at least partially automatically using the drill string by the top drive comprising a drill mode, a make-up mode, an orient mode, and a rocking mode, and wherein the remote control comprises: (i) a torque control and monitor comprising:
1. a right hand torque and left hand torque display connected to the torque pin sensor for displaying simultaneously and in real time right hand torque pressure and left hand torque pressure applied to the drill string by a member of the group, comprising:
a. lithe top drive;b. a mud motor; andc. combinations thereof;2. a torque release actuator;3. a drill torque control connected to the hydraulic pump;4. a make-up torque control connected to the processor; and5. a mode of operation selection means; (ii) a speed control and monitor comprising:
1. a speed display in revolutions per minute connected to the speed sensor for displaying revolutions per minute applied to the drill string in real time by the top drive;2. a speed selection means connected to at least one of the processors; and3. a rotational selection means to control rotation of the drill string wherein the rotational selection means allows a rotational direction to be selected, wherein the rotational direction comprises a clockwise rotation, a counter-clockwise rotation, and a stop; c. computer instructions in the data storage to compare data from the torque pin sensor to a top drive torque maximum or a specified number of turns for the drill string to rock the drill string; d. computer instructions in the data storage for establishing a maximum torque while drilling in a clockwise direction or a specified number of turns for the drill string in a clockwise direction; and e. computer instructions in the data storage for establishing a maximum torque while rotating the drill string in a counter-clockwise direction or a specified number of turns for the drill string in a counter-clockwise direction.
