Abstract: Numerical simulation of instrument response is an important method for instrument parameters calibration, detection performance evaluation, and complex system theory verification. Measurement results of electrical well logging are important to interpretation of measurement data and characterisation of oil reservoirs, especially in horizontal directional drilling and shale gas and oil development. In this paper, self-adaptive hp finite element method has been used to investigate the electrical well logging instrument response, such as electromagnetic wave resistivity logging-while-drilling (LWD) tool and through casing resistivity logging (TCRL) tool. Measurement results illustrate the efficiency of methods, and provide physical interpretation of resistivity measurements obtained with LWD tool and TCRL tool. Numerical simulation examples are provided to show the validity, accuracy, and efficiency of self-adaptive hp finite element method. And the high accuracy simulation results have great importance to electrical well logging tools calibration and logging data interpretation.

Keywords: numerical simulation; parameters calibration; electromagnetic wave resistivity logging-while-drilling; LWD; through casing resistivity logging; TCRL; self-adaptive hp finite element method.
