Systems and methods for interpreting multi-phase fluid flow data

摘要

Methods and systems are disclosed for interpreting multi-phase fluid flow in a conduit, such as a pipe in a wellbore. The method involves curve fitting holdup data sets and velocity data sets together wherein the second curve comprises a shape mutual to the first curve with an independent gain and an independent offset, and determining flow rates through the pipe.

1. A method for interpreting measurements of a multi-phase fluid flow in a conduit, the method comprising:
obtaining a set of holdup measurements from a holdup sensor; obtaining a set of velocity measurements from a flow velocity sensor; using one or more processors, fitting a first curve to a first set of the holdup measurements and a first set of velocity measurements; and using one or more processors, fitting a second curve to a second set of holdup measurements and a second set of velocity measurements, wherein the second curve comprises a shape mutual to the first curve with an independent gain and an independent offset; and determining a flow rate for one phase of the multi-phase fluid flow based on the first and second curves.
