METHOD TO PREDICT SONIC LOG AT BIT IN REAL TIME

原文（中国語）

A method and/or system comprising disposing a logging tool into a borehole, wherein the logging tool comprises: a transmitter configured to transmit a sonic pulse into a borehole; and one or more receivers configured to detect reflected sonic pulses as measured sonic data. Further, the method and/or system may be further comprise forming a correlation between the measured sonic data and one measurement from the sonic data and the one or more drilling parameters; and predicting sonic data at a bit with the correlation and one or more drilling parameters. In addition to acoustics the method and/or system maya downhole transmitter configured to transmit a particle and/or wave into the borehole and observe a response from the particle and/or wave, wherein the response is a reflection of or an effect of the particle and/or wave within the borehole or within a formation surrounding the borehole.
