Hydrodynamiczne modelowanie basenów osadowych na przykładzie basenu permskiego monokliny przedsudeckiej

Theoretical fundamentals of modelling and hydrodynamic classification of sedimentary oil basins are presented in the paper. Hydrodynamic classification of oil basins is based on the effects differentiating the liquid phase, especially the movement of reservoir fluids. Definition of this type of hydrodynamic basin lies in determining its development stage at present: before, during or after the invasion of infiltration waters. Bearing in mind data of reservoir pressures distribution, directions and flow rates of groundwaters, as well as properties of reservoir fluids, three main types of sedimentary basins have been distinguished: juvenile (centrifugal), transient (centripetal) and mature (static). Physical phenomena and interrelations taking place between accumulated hydrocarbons and the accompanying reservoir waters and pressures predestine the first type as most perspective; the third type is usually eliminated as non-perspective. The so far final results of hydrodynamic analyses for the Permian basin in the Fore-Sudetic Monocline prompt the conclusion that the basin is a very perspective juvenile (centrifugal) basin.
