DRILL BIT FOR PERFORMING ELECTROMAGNETIC MEASUREMENTS IN A SUBTERRANEAN FORMATION |
摘要 |
A drill bit for measuring the electromagnetic propagation resistivity of a subterranean formation is disclosed. The drill bit includes a shank portion and a cutting portion with a raised face. The drill bit includes a transmitter element and a receiver element disposed on the raised face. The transmitter element propagates electromagnetic waves into a subterranean formation with a frequency of at least one gigahertz. The receiver element is positioned relative to the transmitter element at a pre-determined distance, with the predetermined distance is based, at least in part, on the frequency of the electromagnetic wave. |
