| Abstract: | The purpose of the investigation is to reveal the dependences of P p = f(C p) on reservoir conditions and the lithological composition of rocks. The samples were studied using a set of lithological-petrographic investigations. To obtain the dependences on thermobaric conditions, 90 samples of different porosities (C p) of 15, 20, and 25% were collected. As a result, the general pattern of the change in the rock resistivity during the transition from atmospheric conditions of measuring to reservoir conditions was established. Dependences of porosity parameter P p on porosity coefficient C p were obtained for three values of formation water salinity and three reservoir conditions. The measurement errors of the porosity parameter P p were calculated using dependences obtained under atmospheric conditions. |
