Abstract

Present embodiments are directed to a control system including a controller configured to regulate a drilling fluid flow through a pipe element during installation of the pipe element into a wellbore or removal of the pipe element from the wellbore, wherein the controller is configured to regulate the drilling fluid flow based on feedback from one or more sensors of the control system.

First claim

The invention claimed is:

1. A pipe drive system, comprising:
a gripping device configured to couple with a pipe element;
a sealing mechanism comprising a seal disposed between the gripping device and the drill pipe element;
a strain gauge disposed on the seal and adapted to measure seal pressure;
a pump configured to pump a drilling fluid flow through the gripping device and the pipe element while the pipe element is being installed into or removed from a wellbore; and
a controller configured to regulate a flow rate of the drilling fluid flow while the pipe element is being installed into or removed from the wellbore based on one or more operating parameters associated with installing or removing the pipe element from the wellbore, the one or more operating parameters, comprising the seal pressure.

2. The system of claim 1 , wherein the controller is configured to regulate operation of the pump based on feedback from one or more sensors, wherein the one or more sensors are configured to measure operating parameters of a drilling rig.

3. The system of claim 2 , wherein the operating parameters comprise a pressure within the wellbore, a vacuum within the wellbore, an installation or removal rate of the pipe element, a flow rate of the drilling fluid, or any combination thereof.

4. The system of claim 1 , wherein the sealing mechanism is configured to create a sealing interface between the gripping device and the pipe element and facilitate flow of the drilling fluid through the gripping device into the pipe element.

5. The system of claim 1 , comprising:
a housing of the gripping device configured to extend over and at least partially around a distal end of the pipe element; and
clamp devices configured to engage an outer circumferential surface of the pipe element with frictional engagement features that extend radially inward from the housing.

6. The system of claim 1 , wherein the controller is configured to regulate the pump to pump the drilling fluid through the gripping device and the pipe element proportionally to the volume of the pipe element being installed into or removed from the well bore.

7. A control system, comprising:
a seal disposed between a drillpipe element and a gripping device configured to grip the drill pipe element;
a strain gauge configured to measure seal pressure of the seal, the seal pressure corresponding with one or more operating parameters associated with installation or removal of the drill pipe element from the wellbore; and
a controller configured to regulate a drilling fluid flow rate through the pipe element during installation of the pipe element into a wellbore or removal of the pipe element from the wellbore, wherein the controller is configured to regulate the drilling fluid flow rate based on the seal pressure of the seal.

8. The system of claim 7 , wherein the control system comprises the one or more sensors, and the one or more sensors are configured to measure one or more operating parameters of a drilling rig having the controller.

9. The system of claim 8 , wherein the controller is configured to regulate operation of a mud pump based on the one or more operating parameters measured by the one or more sensors, wherein the mud pump is configured to pump the drilling fluid flow.

10. The system of claim 8 , where in the one or more operating parameters comprises a pressure within the wellbore, a vacuum within the wellbore, a flow rate of the drilling fluid, an installation rate of the pipe element, a removal rate of the pipe element, or any combination thereof.

11. A method of assembling or disassembling a drill string, comprising:
circulating a drilling fluid through the drill string and into a wellbore in which the drill string is disposed with a pump during installation or removal of a drillpipe element of the drill string;
measuring one or more operating parameters associated assembling or disassembling the drill string, wherein the one or more operating parameters comprises a seal pressure of a seal disposed between a gripping device configured to grip the drillpipe element and the drillpipe element, wherein the seal pressure is measured by a strain gauge disposed on the seal; and
controlling a flow rate of the drilling fluid based on the one or more operating parameters.

12. The method of claim 11 , comprising pumping the drilling fluid through the drill string and into the wellbore at a rate proportional to an installation rate or a removal rate of the drill pipe element of the drill string into the well bore or from the well bore.

13. The method of claim 11 , wherein controlling the flow rate of the drilling fluid based on the one or more operating parameters comprises initiating operation of a mud pump configured to pump the drilling fluid.

14. The method of claim 11 , wherein controlling the flow rate of the drilling fluid based on the one or more operating parameters comprises opening a valve configured to regulate flow of the drilling fluid.

15. The method of claim 11 , wherein the one or more operating parameters comprises a pressure within the wellbore, a vacuum within the wellbore, a flow rate of the drilling fluid, an installation rate of the drillpipe element of the drill string, a removal rate of the drillpipe element of the drill string, or any combination thereof.

16. The method of claim 11 , comprising increasing a flow rate of the drilling fluid after the drillpipe element is removed from the wellbore.

17. The method of claim 11 , comprising injecting compressed air into the drillpipe element after the drillpipe element is removed from the wellbore.

18. The method of claim 11 , comprising pumping the drilling fluid through the drill string and into the wellbore at a rate faster than a removal rate of the drill pipe element of the drill string from the well bore.
