Popis: In this article the horizontal wells productivity analysis has been hold in respect of edge-typed oil rims developed with depletion recovery drive with gas breakthrough. There are several methods that may help to calculate producion rate of the wells in underlayng oil rims without gas breakthrough (so called critical rate). These methods were obtained due to the relatively simple well drainage area. Considering the of edge-typed oil rim geometry with different saturation zones we get much more complicated boundary conditions and the numerical solution is needed. Main criteria that influence on the character of filtration flows in underlaynig and edge-typed oil rim were formulated. Various simulation runs on 2D "X-Z" model were perfomed to investigate coining peculiarities especially different coning regimes and it’s influence on the oil production rate. Main results of the work are the corrleations between dimensionless oil rate and geometrical parameters of edge-typed oil rim that also may help to calculate economical efficiency of the oil rim development.
