Analysis of Factors Influencing the Flow Velocity of Heavy Oil Gravity Drive

Abstract:

Based on the assisted gravity draining steam flooding and the development technology of drive drain compound, using computational fluid dynamics software ANYSY CFX to analyze the impact of the reservoir with the angle of inclination and oil reservoir thickness and density of the crude oil on the oil (water) flow velocity. Research shows that: when the density of crude oil is close to the density of water, the speed difference is reduced. When the tilt angle is between 20^o and 60^o, the flow velocity was significantly reduced. When the reservoir thickness is between 20m and 40m, the growth of seepage velocity is more evident. Research results provide reference for seepage study of gravity drive of heavy oil .
