METHOD OF DEFINING EXTREME FLUID FLOW RATES IN WELL (VERSIONS)

摘要

FIELD: oil-and-gas production. ^ SUBSTANCE: in compliance with this invention, thermal flowmeter is used to measure flow rates along well bore in direction coinciding with fluid flow directions and make measurements in killed well. Results of said measurements are used to construct graphs of thermal flowmeter readings vs its displacement speed to determine fluid flow rate in well. ^ EFFECT: expanded range of flow rate determination. ^ 2 cl, 3 dwg, 1 ex
