Abstract
The authors summarized and systematized the available data of the structure of the void space and complex carbonate reservoir types. The data of the well logging for about 500 layers of carbon rocks of the Rudenkivs’ko-Proletars’ka area (Dnieper-Donets Basin) were used. This area includes 7 deposits: Bagatoys’ke, Gnatívs’ke, Leventsívs’ke, Machus’ke, Novomikolaivs’ke, Pereshchepins’ke and Yur’ivs’ke. The materials of the national funds and the data base of Taras Shevchenko National University of Kyiv were attracted.
We have registered the most complex types of the reservoir void space for the Novomikolaivs’ko-Machus’kiy field. This is caused by the significant development of the cavernous voids. More than 35% of the rocks contain the have cavernous porosity. At the same time the cavernous porosity is present only in the 14% of reservoirs for other studied deposits.
These two groups of deposits are characterized by a different structure of the void space: the first group has 43.72% of the fractured-pore and 1.4% pore-fractured reservoirs, and the second group has 5.8% and 58.29% respectively. Moreover, approximately the same number of pure pore (5.8%) and purely fractured reservoirs (about 15%) was found for all deposits in this region.
