Abstrakt: A model problem on the recovery and redistribution of pressure fields in the stratum on reduction in the flow rate of wells has been solved on the basis of the law of filtration with a limiting gradient proposed earlier. The possibility of judging the filtration properties of the stratum from the form of the pressure recovery curve has been shown. It has been established that an analysis of this curve enables one to reveal a deviation of the filtration law from Darcy′s linear law in low-permeability strata. [ABSTRACT FROM AUTHOR]
