System for Production Boosting and Measuring Flow Rate in a Pipeline

摘要

A system for measuring flow rate in a pipeline by use of a surface jet pump that receives input from both a high pressure pipeline and a low pressure pipeline. Rather than installing flow meters at any or all of the inputs/output from the SJP which is an expensive undertaking, flow rate is predicted by utilising existing pressure sensors located on the high pressure pipeline, low pressure pipeline and discharge pipeline respectively. A control processor predicts flow rate based on correlations between flow rate and pressure for a given SJP geometry and, for example, utilises momentum, conservation of mass and continuity equations, balanced against the pressure forces and velocity in the SJP.

1. A system for measuring flow rate in a pipeline, including:
a high pressure pipeline; a low pressure pipeline; and a surface jet pump receiving input from both the high pressure pipeline and low pressure pipeline;a discharge pipeline of comingled products output from the surface jet pump;
at least three pressure sensors located on the high pressure pipeline, low pressure pipeline and discharge pipeline respectively; a control processor monitoring information input from the pressure sensors; wherein the control processor predicts a flow rate in at least one of the high pressure pipeline, low pressure pipeline and/or discharge pipeline based on correlations between flow rate and pressure for a given surface jet pump geometry.
