Acoustic well logging method and system
This patent describes a system for acoustic well logging of a borehole comprising: (a) a logging sonde having acoustic energy transmitter smitter means for imparting first acoustic energy into the borehole and a plurality of acoustic energy receiver means spaced at selected distances from the transmitter means for recording first signals representative of the first acoustic energy whereby measures of Stonely wave velocity and formation compressional wave velocity can be obtained; (b) a subassembly adapted to e connected with the logging sonde wherein the subassembly includes: (i) interior surfaces forming a transverse passageway therethrough, wherein the transverse passageway includes arcuate surfaces at opposite ends adapted to direct the flow of boreholefluid therethrough during upward and downward movement of the logging sonde and subassembly in the borehole; (ii) first transceiver means mounted circumferentially with the subassembly for imparting second acoustic energy into the borehole and recording a second signal representative of the second acoustic energy after reflection from the borehole wall.
