FIELD: instrumentation.
SUBSTANCE: use: to detect component composition of rocks of chemogenic deposits. The substance of the invention consists in the fact that geophysical survey is carried out by acoustic, gamma-density, neutron and gamma-spectral methods along a well shaft in section of chemogenic deposits with sampling frequency by depth of 0.1 m and at each point of depth, by means of algorhythmic solution of a system of equations with four measured geophysical parameters and available physical properties of skeleton part of rocks they determine quantitative content of 5 prevailing components of rock, including halite, anhydrite, sylvinite, calcite and clay.
EFFECT: increased accuracy and validity of detection of lithological composition and evaluation of quantitative content of rock components in sections of chemogenic deposits.
