Abstract
The work is devoted to solving the problem of determining the clayness of reservoir rocks with complicated cross-sections carboniferous deposits at Narijnianske gas-condensate field. The results of determination clayness according to laboratory and well geophysical studies are considered. To solve the problem, a comprehensive approach is proposed regarding to use the results of acoustic, neutron and gamma-gamma-density methods. Petrophysical models of interconnection mass clayness with rock density and porosity coefficient were constructed. . As a result, it has been established that mass clayness practically do not affect to the volumetric density of rock. A spatial model of roof productive horizon C5 at Narijnianske gas-condensate field was constructed.
