Abstract:

An electronic circuit for multi pole array acoustic logging receiver was designed for petroleum tools. This circuit consists of signal amortization, signal synthesizers, pattern selection，two stage bandpass filters and program-controlled attenuators & amplifiers. It can transduce the signals received by receiver transducer into monopole signals, dipole signals and quadrupole signals. So it can be used for receiving, composing and filtering of acoustic signals, as well as for program-controlled attenuating & amplifying of acoustic signals. With simplified structure design, it can receive monopole signals, dipole signals and quadrupole signals, and is effective in attenuating & amplifying signals with little signal interference. Moreover, with the feature of compact structure, it is flexible for upgrading, easy for interface extension, and simple for control. It shows excellent performance, and can find good application in high performance downhole tools.
