method for compensation of pressure measurements made by a pressure gauge and system for thermal compensation of pressure measurements made by a pressure gauge

摘要

method for compensating pressure measurements made by a pressure gauge, method for performing one or more pressure measurements with a pressure gauge, and system for thermally compensating pressure measurements made by a pressure gauge. methods and systems for thermal compensation of pressure measurements made by a pressure gauge. Pressure value errors are reduced by using a predetermined correlation between the pressure measurement error due to a temperature gradient on a pressure gauge and the temperature gradient caused by the temperature on a pressure gauge surface. and the temperature on an internal part of the pressure gauge. Thermally corrected pressure values are derived based on the correlation between pressure errors and temperature gradients under conditions such as due to rapid and substantial pressure variations in oil wells.
