Abstract
Results of petrophysical studies of core samples from Semyrenkivska area wells are presented. Variable pressure influence on the pores volume and distribution in the reservoir rocks was determined both qualitatively and quantitatively. Amounts of total, intergranular, fracture, vugular and secondary porosity were estimated. Linear relationship between the pores volume under reservoir and atmospheric conditions was established. Dependence of different porosity types on pressure was approximated by the power functions. Presented relationships can be used for the productive horizons of Semyrenkivska area or adjoining territories with similar petrophysical and other properties. These relationships with determined validity coefficient can be used to determine changes of the reservoir properties of rocks during the field exploitation on the basis of core laboratory studies.
