LONGITUDINAL FRACTURE INFLUENCE ON THE UNFOCUSED LATERAL LOGGING SOUNDING RESPONSES IN HIGH-RESISTIVITY DEPOSITS

The article considers the analysis of unfocused lateral logs (BKZ) simulated in three-dimensional media models with a vertical fracture. It was found that for the Tomsk region Upper Paleozoic deposits conditions the influence of a single thin fracture passing through the well axis on the signals is equivalent to the influence of the invaded low resistivity zone. On the practical data measured in the well of Archinskoe oil-gas-condensate field (Tomsk region) we discuss the possibilities of numerical data inversion for identifying oil-productive intervals.
