摘要：In order to get a previous understanding about data transmission effect through a long well-logging cable (about 7000 m), a lumped parameter circuit simulating the attenuation characteristics of well-logging cable was designed in this paper. Based on the actual attenuation measurement at every discrete frequency point, the analytic expression of transfer function of the cable was firstly obtained by nonlinear fitting method, then a physically realizable circuit model corresponding to the transfer function was thus established. According to the simulation results, the circuit model shows good fitting effect to the cable attenuation characteristics.
