Direct measurement of multiphase flow using controlled relrease of polymers soluble in single phase

摘要

Polymeric inserts containing minute amounts of radioactive substances (at safe levels) can be applied to measuring multi phase flows in pipelines, including those carrying crude oils. Several water and oil soluble polymeric systems were tested, and some were found to be applicable to the described measurements. The tests were performed under field conditions with varying pressures, temperatures, composition and flows of liquid phaees. This novel, on line,m direct measuring methodology is very simple, accurate and does not require sample collection.
