Introduction

Analysis of the core content of the standard

GB/T8423.4-2022, as the basic terminology standard for the petroleum and natural gas industry, systematically standardizes the professional terminology in the field of oil and gas metering and analysis, including the definition requirements for key equipment such as metering tanks and flow meters.

Comparison of metering equipment terms

Terms	Definition points	Application scenarios
Vertical metal tanks	Vertically installed cylindrical metal tanks, including fixed roof/floating roof types	Crude oil storage and custody transfer
Coriolis mass flowmeter	Using the principle of interaction between fluid and vibrating tube	Dynamic measurement of liquid hydrocarbons
Ultrasonic flowmeter	Measurement of flow velocity by the time difference of sound wave propagation	Natural gas transmission and distribution metering

Key technical parameters

Compressibility factor (Z): In natural gas metering, this parameter corrects the deviation between the actual gas and the ideal gas. The calculation formula is: Z=pVm/(RT), where Z≈1 under standard reference conditions (101.325kPa, 20℃).

Wax precipitation point: The starting temperature of wax crystal precipitation in crude oil, measured by differential scanning calorimetry (DSC), directly affects the pipeline transportation process design.

Standard implementation recommendations

The metering system configuration should meet the requirements of range ratio ≥ 10:1
Flowmeters for trade transfer need to be calibrated in real flow regularly
Multiphase flow metering needs to consider liquid holdup correction
