Definition of productivity of directional wells operated in heterogeneous multi-layered formations
M.N. ShykhiyevThe hydrodynamic task of fluid flow to directional wells, opened multi-layered formation partially or completely has been solved. Reservoir is considered to consist of an arbitrary number of layers with different thickness and permeability coefficient. On the case of development of 3-layered formation with directional well, the hydrodynamic calculations have been conducted and rates of directional well depending on the deviation angle between vertical direction and downhole of the well defined. Various cases of opening of a three-layer formation via directional wells are considered. In the first case it is assumed that the reservoir was completely opened, i.e. directional well is complete, in the second case - opened two layers and in the third - opened one layer of a 3-layered formation by directional wells.
