Abstract The new type of high-resolution dual laterolog tool has been gradually put into large-scale application in production, which can provide powerful support for the exploration and development issues solving the thin-layer reservoir in oil fields. The paper used finite-element algorithm to carry out numeric simulation for such response characters as layering ability, depth of investigation, influences of invasion and borehoe of new type of high-resolution dual lateralog tool and ordinary dual laterolog tool that has been used in large scale at home up-to-now. The numeric simulation showed that in comparison with common dual laterolog although the influence of borehole on high-resolution dual laterolog data is more complex, the surveying results were characteristics of both higher vertical resolution and deeper radial depth of investigation, which can basically be applied in logging to replace common dual laterolog tool. The results of numeric simulation in the paper gave reference and guide to logging workers and interpreters in data check and interpretation as well as processing.
