Apparatus and methods for detecting performance data in an earth-boring drilling tool |
摘要 |
Methods and associated tools and components related to generating and obtaining performance data during drilling operations of a subterranean formation is disclosed. Performance data may include thermal and mechanical information related to earth-boring drilling tool during a drilling operation are disclosed. For example, a cutting element of an earth-boring drilling tool may include a substrate with a cutting surface thereon. The cutting element may further include at least one thermistor sensor coupled with the cutting surface, and a conductive pathway operably coupled with the at least one thermistor sensor. The at least one thermistor sensor may be configured to vary a resistance in response to a change in temperature. The conductive pathway may be configured to provide a current path through the at least one thermistor sensor in response to a voltage. Other methods, tools and components are provided. |

1. A cutting element for an earth-boring drilling tool, the cutting element comprising:
a substrate with a cutting surface thereon; at least one thermistor sensor coupled with the cutting surface, the at least one thermistor sensor configured to generate an output in response to a change in temperature relating to a parameter of interest of the cutting element when the cutting element is drilling a borehole.
