Abstract
Methods and systems of for tripping pipe on a rig floor positioned over a well are provided.
Claims26
A method of tripping pipe on a rig floor that is positioned over a well, the method comprising the steps of:
- providing a first drill pipe having upper and lower ends;
- providing a second drill pipe having an upper end extending in a vertical direction above the rig floor by a stick-up height;
- measuring a length characteristic of the first drill pipe;
- calculating, based upon the measured length characteristic of the first drill pipe and the stick-up height of the second drill pipe, a vertical position into which it is necessary to place the first drill pipe to complete a tripping process for the first and second drill pipes;
- and
- moving the first drill pipe into the vertical position.
A method of tripping pipe on a rig floor positioned over a well, the method comprising the steps of:
- providing a first drill pipe having an upper end and a lower end;
- providing a second drill pipe having an upper end extending in a vertical direction above the rig floor by a stick-up height;
- providing a controller configured to control machinery for drilling the well;
- measuring a length characteristic of the first drill pipe;
- inputting the length characteristic of the first drill pipe into the controller;
- wherein the controller is further configured to calculate, based upon the measured length characteristic of the first drill pipe and the stick-up height of the second drill pipe, a vertical position into which it is necessary to move the first drill pipe to complete a tripping process for the first and second drill pipes;
- and
- operating the controller to calculate the vertical position.
On a drilling rig having a rig floor positioned over a well and having machinery for drilling into the well, a system for tripping a first drill pipe having an upper end and a lower end and a second drill pipe having an upper end extending above the rig floor by a stick-up height, the system comprising a controller that is configured to calculate, based upon a length characteristic of the first drill pipe and the stick-up height of the second drill pipe, a vertical position into which it is necessary to move the first drill pipe to complete a tripping process for the first and second drill pipes, wherein the controller is further configured to control the machinery to move the first drill pipe into the vertical position and to complete the tripping process for the first and second drill pipes.
