Integrated approach to the optimization of development of fields with hard to recover reserves

The microstructure analysis of pre-oriented in space core sections is executed. Two general directions of filtration and fluid migration of hydrocarbons, associated with the secondary and intergrain porosity, are established. The detailed geological and filtration model, which formed the basis for the analysis of the applicability of the complex of the secondary (hydrodynamic) and tertiary (physical) methods of an oil recovery increase, is constructed.
