Abstract

An azimuthally acoustic while drilling signal receiving transducer encapsulating apparatus includes a drill collar, a receiving transducer, a preposed signal processing circuit and a master control electronics housing. The receiving transducer and the preposed signal processing circuit are encapsulated on a drill collar body individually. The receiving transducer and the signal processing circuit are electrically connected by a sealing electrical connector. The preposed signal processing circuit and the master control electronic housing are electrically connected. The signal processing circuit is preposed in terms of signal processing, and encapsulated on the drill collar, so that signal receiving and processing cable length is shortened and noise interference is reduced.
