METHOD FOR DETERMINATION OF POROSITY OF LOAMY ROCKS IN OIL AND GAS WELLS

摘要

The invention relates to means for geo-physical investigations of oil and gas wells. Method for determination of porosity of loamy rocks in oil wells is in use of method of acoustic logging () with registration of interval time of propagation of longitudinal waves for determination of porosity by method of and entering correction on clayiness as coefficient at porosity determined by method. Correction on clayiness is obtained by means of gamma-logging (GL) with use of double difference parameter GK. The invention provides increase of self-descriptiveness and reliability and increase of area of implementation of for numerical evaluation of porosity of loamy collectors.
