METHOD FOR EVALUATION OIL OR GAS WELL PRODUCTIVITY

摘要

Usage: to determine the productive characteristics of petroleum and gas wells. SUMMARY OF THE INVENTION: measured flow rate and the bottom hole pressure at steady state and for equal periods of time in several neustanovivshihs modes. By formulas using the values ​​obtained was determined ustanovivshees value of flow rate and pressure downhole for each neustanovivshegos mode. The obtained value m determined by the well productivity index. Duration Studies on each neustanovivshems mode is set to half the time needed for stabilization mode. 1 yl.
