Simulation device for wireline logging ground auxiliary signals

The invention discloses a simulation device for wireline logging auxiliary signals. The simulation device comprises a depth signal generation module, a tension signal generation module, an MMD signal generation module, a signal acquisition module and a power control module. The depth signal generation module generates a depth signal through a motor and a depth encoder and transmits the depth signal to the signal acquisition module; the tension signal generation module generates a first direct current signal through a first direct current signal generation circuit, simulates a tension signal through the first direct current signal and transmits the tension signal to the signal acquisition module; the MMD signal generation module generates a second direct current signal through a second direct current signal generation circuit, simulates an MMD signal through the second direct current signal and transmits the MMD signal to the signal acquisition module; the signal acquisition module outputs the depth signal, the tension signal and the MMD signal; the power control module is used for supplying power to the depth signal generation module, the tension signal generation module, the MMD signal generation module and the signal acquisition module. By means of the simulation device for the wireline logging ground auxiliary signals, simulation on the depth, tension and MMD ground auxiliary signals is achieved.
