A tubular member having at least one drainage section (1) including a first plurality of self-adjustable valves or flow control devices (2) to control the flow of fluid into the drainage section from a well formed in a subterranean reservoir, each of the valves (2) comprising an inlet or aperture (10), thereby forming a flow path (11) through the control device (2) passing by a movable disc or body (9) designed to move freely relative to the opening of the inlet and thereby reduce or increase the flow-through area (A2) by exploiting the Bernoulli effect and any stagnation pressure created over the disc (9), whereby the valve (2), depending on the composition of the fluid and its properties, autonomously adjusts the flow of the fluid based on a pre-estimated flow design. To allow injection of fluid into the subterranean reservoir, the drainage section (1) is provided with a second plurality of such self-adjustable valves (32), each being situated in a direction opposite of the first plurality. |
