Key words: micro-layering, shaliness, core, interpretation's algorithm.

Determining the proportion of clay layers from photographs core allows to assign an additional petrophysical parameter required for the development of petrophysical model of thin-layer rocks and algorithms for interpretation of well logging techniques. In this work examine a method for determining the proportion of clay layers from photographs core, based on a contrast of texture- component heterogeneous rock. The advantages of this method are the speed and reliability of results.
