Multiparallel Method in the Theory of Plane-Parallel Nonstationary Filtration.

The multiparallel method, or the method of generalized similarity, is used to calculate nonstationary filtration flows. A ″universal″ equation and an integral relation necessary to solve particular problems, about putting a well into operation are obtained. Integration of the ″universal″ equation was carried out taking account of the first two parameters. The method is relatively simple in practical application and yields good convergence for short filtration times, thus permitting calculation of problems with ″fast″ periods of transient processes.
