Key words: wettability, core, oil, water, lab test.
In the present work the results of comprehensive analysis on estimation of wettability using the samples of Jurassic deposition of terrigenous profile of oil deposit are presented. Changes in wettability were estimated by two well-known Tulbovich and Amott methods with extracted samples. The influence of wettability on relative permeability to phase was investigated. As a result of the investigations remarkable change in wettability coefficient has been shown to occur during the first 24 hours. The increase in curing time in stratal conditions does not effect on wettability coefficient and permeability to phase.
