In recent years study of petrophysical features of hydrocarbon fields, determination of perspective areas for well drilling, control on exploitation of objects are carried out on the basis of joint analysis of (3D) seismic data and results of well geophysical researches (WGR). For the purpose, 3D seismic, geological, petrophysical, hydrodynamic effective models, compiled on the basis of 3D seismic data of fields and WGR have been used. Density factor for the area of 1km2 drilled in the exploiting fields of the lands of Azerbaijan gives opportunity to compiling of any model of most exploiting fields on the basis of WGR results. In this case, models are compiled according to the following phases: - correlation of geological broken in the basis of mutual comparison of carotage information; - specification of lithology-stratigraphic division of geological broken; - compiling of lithology-stratigraphic and lithofasial maps ; - assignment of petrophysical features of collectors and their estimation in the basis of quantity factors; - calculation of porosity and conductivity coefficients; - forecasting of hydrocarbon reserves of the field.
