| Interpretation of the type oil reservoirs of Osa productive unit - the Markovo field (Eastern Siberia) study using modern geological and geophysical data | |
| The oil accumulations of the Osa productive unit belong to the lithologically screened type, complicated by a system of tectonic disturbances of submeridional strike. The use of geological and field data made it possible to delineate a zone of increased productivity, which represents a zone of destruction of unit rocks. Hydrodynamic connectivity between wells in the unit was confirmed by the results of hydrodynamic testing. Biohermic limestones and heterocrystalline dolomites have the best reservoir properties. The dominant role in the classification of “reservoir-non-reservoir” rocks is played by soluble minerals, the amount of which determines the reservoir properties. The void space in these rocks is represented by residual voids and leaching voids. Using an of the quality, classification and distribution of reservoirs, maps of oil-saturated effective thicknesses were constructed and hydrocarbon reserves were calculated. Keywords: reservoir classification, reservoir properties, zone of increased productivity, Osa productive unit, map of oil-saturated effective thicknesses, Markovo field, Eastern Siberia. |
