阵列声波接收换能器的隔声及防震设计

Sound Insulation and Shockproof Design for Receiving Transducer in Array Acoustic Logging Tool

随着多极子阵列声波测井仪在各油田的广泛应用,阵列声波测井仪器在设计时不但要考虑机械结构的稳定性,更要考虑声波的隔声效果,避免声波沿着机体及个连接部分传播。用一维声波传播模型给出了一种隔声设计方法,对接收换能器阵列整体隔声以及各个换能器之间的隔声特征进行了分析,给出了隔声效果比较好的设计。

With using of muhipole acoustic logging tool in oilfields, the design of array acoustic logging tool not only considers mechanical structure stability, but also thinks over sound insulation effect, and then avoids the sound wave propagation along the body and joining parts of receiving transducer. With the help of 1 D sound propagation model, a method of sound insulation design is gived. The sound insulation properties of the whole receiving transducer and each of them are analyzed, the better sound insulation design is found.
