The different ways of determination of coefficient of open porosity of terrigenous collectors with regard clayness according to acoustic logging. Coefficients of porosity in these ways and petrophysical relationships were compared with the results of study of core material. For comparison of determined values of porosity coefficient the apparatus of mathematical statistics was used in order to systematize the information received and to estimate the distributions characteristics of this value.
Purpose. The aim of the work is developing the methodology of the prediction of oil-gas-water-saturation of rocks in open-casts of wells based on the data of acoustic (seismic) logging (АL, SL) and core research (CR) and its approbation for wells’ geological open-casts research of rocks of different lithology and geodynamic genesis. Methodology.
