METHOD FOR GAS-HYDRODYNAMIC RESEARCH OF WELLS Russian patent published in 2004 - IPC

FIELD: gas industry.

SUBSTANCE: method involves measuring gas pressure, temperature and output rate at established well operation modes; processing resultant data and determining experimental coefficients of indicator lines; calculating production rates for each operation mode by coefficients of indicator lines of current research; determining factor characterizing deviation thereof from production rate values produced from measurements; calculating, on the basis of coefficients of indicator lines produced upon processing of previous research data, production rate for each operation mode; determining factor characterizing deviation thereof from production rates calculated by coefficients of indicator lines of current research; in case both factors are less than predetermined values, closing researches, and in case one or both factors are greater than or equal to predetermined values, carrying out additional researches for correcting well characteristics.

EFFECT: increased precision in results of gas-hydrodynamic researches of wells and reduced time for analyzing said results.
