Abstract

In this paper, the geosteering technology of drilling tool, relatively bottom of oil horizon in oil and gas reservoir was proposed. A theoretical model of borehole logging tool, transmitting and receiving ultra-wideband (UWB) electromagnetic pulses was proposed. The pulsed voltage at the output of the receiving antenna of borehole electromagnetic logging tool (BELT), located near the oil-water contact (OWC) was simulated, used experimentally tasted models of complex dielectric permittivity (CDP) of oil-saturated rock. The principal possibility of detecting the reflected pulse from transition layer which separates the oil-saturated rock from water-saturated rock and determine the distance to OWC was shown.
