摘要： A method and apparatus for processing acoustic data recorded by a subterranean receiver array. The method includes emitting an acoustic signal into a formation, receiving the signal after it passes through the array, and processing the data with semblance and phase velocity processing. Semblance and phase velocity plots are generated and combined into a single plot. The phase velocity processing creates phase separation lines, the phase separation line that crosses the closest contour of the semblance plot is identified. The point where the intersecting phase separation line crosses an associated tool line marks the slowness and travel time that provides maximum coherence.

摘要： Array quadrupole data obtained in a LWD environment are processed to determine the shear velocity of an earth formation taking into account dispersion effects caused by the logging tool. When this processing is done in an azimuthally anisotropic formation, the shear velocity that is obtained is the slow shear velocity. When 4C (cross-dipole) data are also obtained, then both the fast and slow shear velocities of an azimuthally anisotropic formation can be obtained.

摘要： A method for eliminating the tool mode signal from a received combined signal including both tool mode and formation mode components, uses a signal from a reference receiver that is consists primarily of the tool mode signal. A transfer function is derived relating the time reversed combined signal and the time reversed reference signal and used to predict the tool mode portion of the combined signal. Subtracting the predicted tool mode portion of the combined signal from the combined signal gives an estimate of the formation mode component.

摘要： The logging tool (55) of this invention includes a transmitter conveyed on a drilling collar (90) for exciting a quadruple signal in a borehole (26) being drilled by a drill bit and a receiver for receiving the signal. The transmitter (105) is operated at a frequency below the cut-off frequency of the quadruple collar mode. The received signal consists primarily of the formation quadruple mode which, at low frequencies, has a velocity that approaches the formation shear velocity. The transmitter, in one embodiment, consists of eight equal sectors (101 et al) of a piezoelectric cylinder mounted on the rim of the drilling collar. The value of the cut-off frequency is primarily dependent on the thickness of the drilling collar. Alternatively, the transmitter may be operated to produce both the collar mode and the formation mode and a processor may be used to filter out the collar mode.

摘要： The present invention provides a system (10) for drilling boreholes (26) having a downhole subassembly (59) which contains an acoustic measurement-while-drilling system. The acoustic system contains an acoustic transmitter (T1) and receiver (R) for determining the acoustic velocity through the formations surrounding the borehole ad an acoustic transmitter (T2) and a set of receivers (R1-Rn) for determining the bed boundaries surrounding the borehole formation utilizing the acoustic velocities measured by the system. The downhole subassembly (59) also contains a computing system (150) which performs computations downhole and transmits certain answers uphole during the drilling operations. The bed boundary information is utilized to drill the wellbore along a desired wellbore path. The downhole computing system (150) correlates the acoustic sensor measurements with other measurement-while-drilling measurements and transmits selected correlated information uphole. The downhole computing system (150) contains predetermined well profile which is updated based on the bed boundary information. The system may be adapted to correct or update seismic data and offset well data based on acoustic sensor system measurements.
