发明名称 METHOD FOR IN-SITU CALIBRATING A DIFFERENTIAL PRESSURE PLUS SONAR FLOW METER SYSTEM USING DRY GAS CONDITIONS
摘要 A method and system for in situ calibrating a flow metering system to monitor fluid flow in a pipe from a well is provided. The method includes the steps of: a) measuring a first characteristic of the fluid flow exiting the well using a DP flow meter during a dry gas period, and producing an first output data representative of the first characteristic; b) measuring a second characteristic of the fluid flow exiting the well using a SONAR flow meter time during the dry gas period, and producing a second output data representative of the second characteristic; c) determining a dry gas offset between the DP flow meter and the SONAR flow meter based on the first output data and the second output data; and d) calibrating the flow metering system using the dry gas offset.
