TRACER RELEASE METHOD FOR MONITORING FLUID FLOW IN A WELL |
摘要 |
A tracer release method for monitoring fluid flow in a well utilizes a deformable container comprising a liquid tracer material which container has an outlet which debouches into the neck portion of a venturi in a well conduit. The container has a wall which is at least partly exposed to the fluid pressure at the relatively wide in- or outlet of the venturi, so that an amount of tracer is injected continuously or discontinuously into the well effluents which is proportional to the pressure difference p across the venturi, which pressure difference p is indicative of the fluid density .rho . and squared fluid velocity .upsilon..
