At a choice of a technique of determination of permeability on layers BS10-11 of a field Drujnoye in practice five ways were considered. The analysis of comparisons Kpr = α (PS) showed that data of a method of potentials of own polarization without a kompleksirovaniye with other GIS methods don't meet the requirements shown to determination of permeability. Use of the equations Kpr=f (Kpef) allowed to approximate dependences with big factor of correlation. However, the cumulative error in an assessment of permeability remained at level of one order and led to permeability understating on values to 200 mD whereas the maximum permeability on a core made 1100 mD. Three-dimensional comparison Kpr (Кp) - the code Kgl wasn't applied, since the factor of volume shaliness according to a core has almost identical value of 4-5 % for area of sandstones and aleurolites. Determination of permeability with use of structural factor of S received on the basis of the analysis of capillary curves, had the additional error of definitions connected with uncertainty of provision of a mirror at its finest from 5 to 15м. Comparison use Kpr (Кp) - FZI code (hydraulic units of a stream) appeared the most optimum. FZI are received from the equation of Kozeni-Karmana (taking into account parameter of a form, tortuosity and a specific surface). Adaptation of hydraulic units is carried out with data gamma ray since the mentioned method not only depends on shaliness, but also is defined by polimiktovy composition of rocks, and, therefore, and proceeding secondary processes. At permeability calculation taking into account FZI the error of definitions made 1/3 orders. This method is assumed as a basis at 3D-modeling of layers BS10-11 of the Drujnoye field
