To overcome the technical difficulties of high formation water salinity diversity, big response characteristics alteration of radial resistivity log,low resistivity reservoirs identification ratio, array induction logging with technical superiority was adopted. Its radial invasive characteristics were studied to improve the gas-water layer recognition accuracy. Results of numerical simulation of array induction were introduced and qualitative and quantitative interpretation methods were presented. The analyses of static and dynamic characteristics of drilling fluid invasion provided a theoretical basis for interpretation of oil and water layers. The radial invasive characterization method of array induction imaging logging was proposed and an oil-water layer recognition method based on it was developed. The technology achieved good application effect.
