基于FLUENT的流量控制阀优化设计及试验

Optimum Design and Experiments of Inflow Control Device Based on FLUENT

在水平井开发过程中,由于底水锥进、跟趾效应等原因会导致油井高含水,给油田稳产增产带来困难。利用FLUENT建立自适应流量控制阀的仿真计算模型,对其核心结构进行优化设计,并分析不同工况条件下的性能参数。经试验验证,所设计的自适应流量控制阀的油水流入控制比从常规的4.4倍提高到8.5倍,还可以随着流体黏度的变化,自动调节过流阻力,达到控水增油的设计目的。

During the horizontal well development,high water cut in oil wells,which caused by bottom water coning and heel toe effect,brings difficulties to stable production and increase production.FLUENT was used to establish the simulation calculation model of the adaptive flow control valve to optimize the design of its core structure and analyze the performance parameters under different working conditions.It has been verified by experiments that the oil-water inflow control ratio of the designed adaptive flow control valve was increased from 4.4 times to 8.5 times,and the over-current resistance could be automatically adjusted with the change of fluid viscosity to achieve the purpose of water control and oil increase.
