摘　　要：研究了阵列感应测井仪器的三阶梯波信号的发射与接收特性。通过推导三阶梯波信号的傅里叶展开公式,运用Lab View工具仿真无噪声时8项谐波分量合成的三阶梯波信号的发射与接收特性,仿真具有30%随机高斯白噪声时的发射与接收特性。并分析了基于3倍频信号阵列感应仪器的实际发射与接收特性,实际结果与理论一致,研究成果对阵列感应测井仪器的设计与实现具有一定的指导意义。The characteristics of transmitting and receiving of the three step-wave signal of an array induction logging tool are investigated. First,we derive the three step-wave signal＇s Fourier expansion. Second,in noise free conditions,the characteristic of transmitting and receiving of the three step-wave signal which is composited by eight term harmonics are simulated with Lab View software. The characteristic of transmitting and receiving is simulated when it has 30% ＇s Random Gauss white noise. Finally,we analyze the actual characteristic of transmitting and receiving of an array induction logging tool which is based on the 3 frequency signals. The results are close to the theory simulated.The research results are of great significance to the design and implementation of the array induction logging tool.
