摘要： A method and apparatus for predicting a formation parameter at a drill bit drilling a formation is disclosed. A vibration measurement is obtained at each of a plurality of depths in the borehole. A formation parameter is obtained proximate each of the plurality of depths in the borehole. A relationship is determined between the obtained vibration measurements and the measured formation parameters at the plurality of depths. A vibration measurement at a new drill bit location is obtained and the formation parameter at the new drill bit location is predicted from the vibration measurement and the determined relation. Formation type can be determined at the new drill bit location from the new vibration measurement and the determined relationship.

摘要： An apparatus for drilling a borehole in an earth formation includes: a plurality of drill pipes configured to be coupled together to form a drill string that is configured to convey an earth formation disintegrating device while progressing into the earth formation; a communication medium disposed on the drill string and configured to communicate a signal; and one or more processors. The one or more processors are configured to: receive drilling information; determine a stress distribution along at least a part of the drill string using the drilling information; determine a cumulative fatigue damage of at least a part of one drill pipe in the drill string using the stress distribution; and write the cumulative fatigue damage of the at least a part of one drill pipe to a memory.
