THE DEPENDENCY ANALYSIS OF RELATIVE PERMEABILITY FUNCTION OF OIL-SATURATED RESERVOIR BASED ON THE EXAMPLE OF THE FIELDS IN THE SOUTHERN PART OF THE SURGUT AND NIZHNEVARTOVSK ARCHES

The article deals with the dependence of the function of the relative permeability of reservoirs on their petrophysical characteristics. The analysis is based on the actual data of laboratory testing of core rocks of the productive layers of Vasyugan Oil and Gas Complex (oil fields of the southern part of the Surgut and Vartovsk arch of the West Siberian Oil and Gas Province). The dependence functions of relative permeability from saturation (Van Genuchten – Mualem) is analyzed. The values for the variable power settings based on the relative permeability Van Genuchten – Mualem for specific fields were obtained and their relationship with various petrophysical parameters of the reservoirs was showed.
