Logging tool during drilling of directional resistivity and method for measuring resistivity compensated of logging during drilling

摘要

Logging tool during drilling of directional resistivity and method for measuring resistivity compensated for profiling during drilling a directional resistivity tool (100) includes a pair of transmitters (T1, T2) arranged between at least one pair D And recipients (R1, R2).Each of the transmitters and receivers (T1, T2); R1, R2) preferably includes antennas in Z and X Co located (122, 124, 132, 134; 142144).Methods specimens may also include additional receivers (R3, R4, R5, R6), for example, additional pairs of receivers arranged axially between the transmisspres or a more profound reading receivers (R3, R4, R5) arranged in the axial end of the transmitters (T1, T2).Tools (100) according to the present invention, allow measurement of directional resistivity is acquired in multiple depths of investigation, using fewer shots of transmitter than conventional tools (50).
