Evaluation of postsedimentational process influence on filtration-capacitor properties of chalky deposits of the Western Siberia north

Abstract

The dependences between petrophysical parameters: porosity, volumetric density, permeability and lithochemical characteristics: content of uranium, alumina and value of the U/Al2O3 module, have been examined on the example of Creataceous age productive deposits opened by the Pestsovaya well 209 on territory of Yamalo-Nenetskiy autonomous region. Values of correlation coefficients between volumetric density and alumina content, and also open porosity and alumina content allow evaluating the intensity of secondary mineral formation in collector rocks
