Key words: carbonate reservoir, Tournaisian sediments, fracturing, hydrodynamic model of dual porosity, auto-hydraulic fracturing, hydrochloric acid treatment.

The problems associated with oil recovery from carbonate reservoirs become relevant in recent years due to high depletion of resources in clastic reservoirs and growing proportion of the remaining recoverable reserves in carbonate rocks. The carbonate reservoirs are characterized by a low coefficient of oil recovery associated with the complex structure of the manifold, low porosity matrix, fracturing, vugularity and tectonic faults. It is necessary to adequately describe the processes occurring in the reservoir for the effective development of reserves collectors of this type. This paper presents a method of constructing a hydrodynamic model of carbonate reservoir as example Tournaisian sediments of Mancharovskoe field.
