Abstract: Disclosed is an invasion correction method and system for resistivity logging. The method includes the steps of: analyzing mud filtrate invasion features based on an actual resistivity logging curve; determining an invasion mechanism, and performing forward modeling on a resistivity logging response; performing inversion by a random forest method to form a correction chart; and outputting a formation resistivity to finally form the invasion correction method and system for resistivity logging. In the present disclosure, double lateral correction under an invasion condition is accomplished, while a chart method and an inversion method are combined, ensuring the accuracy and operating rate of correction.
