Study and application of flow control valve based on viscosity sensitivity
In the process of oil exploration,due to such problems as bottom-water coning and reservoir heterogeneity,there may be water outflow at the oil layer,which leads to an accelerated decline in oil production.Therefore,new technologies are constantly applied to completion of oil wells,in order to delay water outflow,control water and increase oil production.In this ar-ticle,a water-control technology is developed based on the flow control valve.It can automatically control the valve's flow rate according to the viscosity of the fluid and restrict the passage of the low-viscosity fluid;to some extent,water control can be real-ized.The CFD software is used to conduct the in-depth research on this technology and explore its working principle and charac-teristics with the help of the flow-field characteristics.The technology applied in Bohai Oilfield has achieved desirable effect of water control and oil production,which provides theoretical basis and technical support for the development of related tools for wa-ter control and oil production.
