FIELD: oil-and-gas production.
SUBSTANCE: in the process of investigation it is implemented measuring of bottom-hole pressure and discharge at continuous duty of well into gas-collecting collector. There are measured parametres of operation of well at its total stabilisation at the mode with maximal debit. There are measured parametres of operation of well at several modes of the same duration by time with different debits. Additionally investigation is implemented uninterruptedly, without stop of well between modes. It is stopped well up to total stabilisation of wellhead pressure. It is taken pressure transient analysis, it is measured strata pressure. It is implemented start-up of well into gas-collecting collector. There are defined coefficients of filtrational resistance A and B.
EFFECT: reduction of consumption of working time for implementation of investigation, increasing of investigations results' accuracy.
