Technical characteristics:

Regulating flow and controlling water sieve pipe is a specially designed flow control device, which realizes automatic identification and flow control of oil and water according to the viscosity, density and other physical property differences of oil and water.

• Low-viscosity formation water is not easy to pass through, and the throttling differential pressure is large;

• High-viscosity oil is easy to pass through, and the larger the viscosity is, the smaller the throttling differential pressure is.

Technology Applications:

• In clastic rock bottom water reservoirs, the use of flow regulating and water control screen tube completion technology can play a good role in prolonging the water-free oil recovery period of horizontal wells and improving the recovery rate of single wells;

• Through blocking and preventive water control completion, it can play a better role in the effect of joint regulating and joint control, and achieve the purpose of overall prolongation of the water-free oil recovery period; 

• In the directional wells that are already high in water content, through the design of reasonable layer section division and flow regulation program, it can significantly reduce the water production of the well, tap the residual oil production capacity of the potential layer, and extend the life cycle of the well.
