AICD adaptive water control screen

AICD adaptive water control screen is based on the principle of the constant sum of fluid dynamic pressure and local pressure loss in the Berlier equation, and controls the opening and switching of the disc in the valve body through the change of different fluid viscosities flowing through the valve body. When the relatively high viscosity oil flows through the valve body, the disc is in the open state. When the relatively low viscosity water or air flows through the valve body, the pressure drop caused by the viscosity change of the disc is automatically "closed", and when it reaches The purpose of controlling water, controlling gas and increasing oil.

Scope of application

●Reservoirs: sandstone reservoirs, carbonate reservoirs, heavy oil reservoirs and other reservoir wells;

●Well type: horizontal well, vertical well, directional well;

●New well: waterproof cone, gas cone, water control, gas control;

●Old well: control water, control gas, increase oil;

● Casing size: 4-1/2 "~ 9-5/8";

●Liquid production: more than 30m3/d;

●Water content in old wells: less than 98%;

●AICD valve is suitable for installation with pipe diameters above 1-1/16 ".

Technical advantages

●You can choose and control the outflow horizon independently without testing to find out the water horizon.

●Control the balanced output of all levels. Effectively control the occurrence of water cone or gas cone in the production process of horizontal wells.

●Waterproof, water control, gas control, sand control, oil increase, multiple goals are completed at once.

●Strong pertinence. According to the specific reservoir parameters and production expectations of horizontal wells, it is designed individually.

●The full diameter of the base pipe is convenient for workover and other operations.
