Abstract
It is known that linear filtering is possible only in a certain range of speeds, while in practice there are cases in which there is a violation of the law of filtration Darcy. Nonlinear filtering characteristic for cases of heavy oil, as well as in terms of simultaneous flow of oil and gas, when the density of the filterable liquid, due to the high gas factor is significantly small. Quite often in practice these fields are developed with horizontal wells. At the same time, due to the use of formulas for calculating a linear filter, in the calculation of well flow rate there is a significant error. In order to avoid such inaccuracies, we derive a formula for determining flow rate of a horizontal well at nonlinear law of filtration for high viscosity, and oil and gas fields. And perform appropriate calculations.
