THE LEVENBERG–MARQUARDT METHOD IN THE PROBLEM OF IDENTIFYING THE ABSOLUTE PENETRABILITY COEFFICIENT OF A BED UNDER CONDITIONS OF TWO-PHASE FIL

The problem of identifying the absolute penetrability coeffi cient of a bed under conditions of two-phase fi ltration by the known values of the fl ow rate of a well at different instants of time is considered. The problem was solved with the use of the Levenberg–Marquardt method and of its two-step variation without and with allowance for the corresponding a priori information.
