Experimental Study on the Simulation Prototype of Acoustic Nipples for Logging-While-Drilling (LWD)

  • 摘要: 针对随钻声波测井中换能器技术及装配的难题,研制了随钻声波测井声系短节模拟样机,基于随钻单极声波测井理论,以指向性、接收响应、单极测量功能等3个指标评价了声系短节及各组成部分的性能及特性。结果表明:发射声系以单极发射向外辐射的声场具有一定的周向均匀性,其指向性接近于一个圆,可组成单极声波发射器;接收器的接收灵敏度均值在-208.0 dB附近,偏差在2.0 dB以内,接收响应一致性良好,可组合相加接收单极声波信号;以单极测量功能进行的模型井整机联调试验获得了套管井波列,提取的套管波传播速度为5245.6 m/s,相对误差小于3.0%。这表明随钻声波测井声系短节具有单极发射、单极接收的测量功能,可用于模拟随钻单极声波测井,为随钻声波测井仪的研制提供试验数据。
