Abstract (en)
[origin: EP2458144A1] A flow control screen for use in oilfield exploitation comprises: a base pipe (1) provided with a base pipe inlet (11) thereon; a filter pipe (2) sleeved over the base pipe (1); a flow guide layer (3) formed between the base pipe and the filter pipe; and a flow control device (4) including an inlet (41) of the flow control device, a flow control channel (42) and an outlet (43) of the flow control device, wherein the inlet of the flow control device is in fluid communication with the flow guide layer, and the outlet of the flow control device is in fluid communication with the base pipe inlet. The pipe is simply structured and cost-effective, and effectively meets the requirements in oil production.
