SIMULATION OF PRESSURE EVOLUTION BETWEEN THE DISTURBING AND LISTENING WELLS IN A LOW-PERMEABLE FORMATION

Based on the previously proposed law of filtration with a limit gradient, the problem of interaction of wells in a low- permeable formation determined by the method of hydraulic listening is solved. The possibility of determining the filtration properties of the formation by the shape of the response curves is established. It is shown that the analysis of such a curve allows one to identify the deviation of the filtration law in the formation from the linear Darcy law
