Since the dual laterolog response is affected by various environmental factors, the instrument response is difficult to reflect the true resistivity of the formation. Plate correction is a common method of resistivity logging environmental correction. Three-dimensional layered media model was established, and the dual laterolog response in directional wells was simulated by three-dimensional finite element method. The influence of environmental factors such as wellbore, well deviation, surrounding rock and mud intrusion on the response of dual laterolog is analyzed emphatically. Therefore, the environmental factors correction plate with different well deviations is constructed, and the plates can be used to guide the dual laterolog environment correction work for better reservoir identification and oil and gas evaluation.
