Abstract
Interval control valve (ICV) is an important part of intelligent well. An ICV was designed and its flow field characteristic was analyzed by the software CFX. With the increase of the ICV opening, the thickness of laminar bottom layer became thinner and the average velocity of the main flow zone increased. The opening had greater effect on the average velocity than the pressure differential. When the ICV was opened or closed, there might be a great shear resistance due to the large inlet flow rate. There was a velocity stagnation point at the intersection of ICV entrance and its axis. The turbulent kinetic energy decreased gradually with the increase of the ICV opening. It was proved that the ICV had a good flow capacity, and the downhole fluid did not produce large pressure drop when it flew through the ICV. The ICV opening - flow coefficient curve could guide the operation of the ICV to achieve the purpose of accurately regulating the production of a reservoir.
