Abstract

The results of studying the petrophysical properties of reservoir rocks selected from deep wells that exposed deposits of carbonate formation of Middle-Upper Jurassic age in the territory of the Central part of the Chardzhou step within the Ispanly-Chandyr, Kultak uplifts and Kushab trough are considered. The article presents data from a comprehensive analysis of the results of studying the petrophysical characteristics of reservoir rocks studied from well cores using lithological-stratigraphic and petrographic parameters of carbonate rocks. On this basis, the filtration-capacitive potential of rocks, the boundary values of reservoirs of productive sediments in the territory under consideration were substantiated, and a map of predictive directions of changes in the boundary values of the filtration-capacitive properties of carbonate rocks was constructed.

Key words:

carbonate formation, Jurassic, limestone, reservoir, seal, petrophysics, porosity, permeability, boundary values
