Abstract:
Instrument structure influences of a new dual-induction resistivity LWD tool were simulated using the finite element method (FEM), and optimal parameters of calibration loop and correction coefficients of the calibration tank were determined and discussed respectively. The results show that the nonlinear responses of the tool are mainly caused by the drill collar and the reflector, while the amplitude enhancement of signal is mainly caused by the magnetic ring. After calibration, a wide linear response range of the formation resistivity is obtained. The simulation results can provide theoretical references for the research and calibration of dual-induction resistivity LWD tools.
