Abstract	A fast and efficient inversion algorithm was suggested for high-resolution dual laterolog (HRDI) tool. The algorithm can yield reliable estimates for the depth of invasion zone and trueformation resistivity simultaneously. Both the behaviour of HRDL measurements and inversion were studied for various bed thickness from 0.4m to 4m. The present results indicated that the HRDI tool improved the vertical resolution obviously, but the its measurements deviate the true value of formation due to the invasion and shoulder effect. These environment influences can be corrected from the inversion process, thus the original formation parameters can be obtained. A site application of the present inversion algorithm gave the distribution of the true-formation resistivity in a real formation scale. It is helpful for log analysts to evaluate the reservoirs.
