DOWNHOLE TOOL FOR MEASURING A FLUID FLOW RATE THERETHROUGH AND A WELL COMPLETION INCORPORATING SAME

摘要

A downhole tool includes a housing defining a passageway therethrough exhibiting a first diameter and a second diameter that is smaller than the first diameter, and a first turbine disposed in the first diameter of the housing. The downhole tool further includes means for measuring a rotational velocity of the first turbine, a second turbine disposed in the second diameter of the housing, and means for measuring a rotational velocity of the second turbine.
