Abstract: The isolation and evaluation of the industrial value of complex reservoirs in the sections of exploration and parametric wells in Turkmenistan is a rather difficult task and is currently not completely solved. To study carbonate reservoirs in domestic and foreign practice, various methods of complex interpretation of diagrams of geophysical well research methods are used, most of which are based on comparing the specific or relative resistance with the readings of acoustic and neutron gamma logging. The value of the carbonate deposits of Turkmenistan is associated with a wide variety of structural forms of their pore space, lithological heterogeneity, low-power formations, etc. As a result, the geophysical characteristics of carbonate rocks are ambiguous; the relationship established between different parameters for one lithological reservoir difference is often invalid for carbonate reservoirs of another lithology. Due to the low porosity of deep-lying reservoir rocks, the requirements for the accuracy of determining reservoir parameters from geophysical materials are significantly increasing.
Key words: porosity, corbonal rocks, resistivity, interpretation, cavernosity, saturation, logging, lithology.
