    • A coupling for interconnecting two double-walled pipes, e.g. production filter pipes (10, 12). The coupling may have the shape of a connector (10A, 12A) divided into two parts, each part (10A, 12A) being attachable on the end portion of a double pipe (10, 12), the parts (10A, 12A) of the connector being interconnectable, preferably mutually screwable. Such double pipes (10, 12) have two concentric liquid passages, one through the inner pipe (14) and one through the annulus-like, concentric liquid passage 920) between inner pipe (14) and outer pipe (16). In order not to block the outer concentric liquid passage (20) at the joint place (10A, 12A) so that liquid flowing therewithin must be transferred to said smaller pipe through a valve, longitudinally extending, through-going flowing channels (18) have been formed in the joint area; said channels (18) may be distributed circumferentially, thus allowing continuous flow of liquid past the coupling area (10A, 12A).
    • 用于互连两个双壁管的联接器,例如。 生产过滤管(10,12)。 联接器可以具有被分成两部分的连接器(10A,12A)的形状,每个部分(10A,12A)可连接在双管(10,12)的端部上,部分(10A,12A) 该连接器是可互连的,优选地相互可旋转。 这种双管(10,12)在内管(14)和外管(16)之间具有两个同心的液体通道,一个通过内管(14),一个通过环状同心液体通道920)。 为了不在接合处(10A,12A)处阻挡外部同心液体通道(20),使得在其中流动的液体必须通过阀传递到所述较小的管道,纵向延伸的贯穿流动通道(18)具有 在联合地区形成; 所述通道(18)可沿周向分布,从而允许液体连续流过耦合区域(10A,12A)。

    • An injection pipe string (4) in a well (2) for the injection of a fluid into at least one reservoir (6) intersected by the string (4), in which at least parts of the injection string (4) opposite the at least one reservoir (6) are provided with one or more outflow positions/-zones. At least one pressure-loss-promoting flow control device is provided to each outflow position/-zone. In position of use, the flow control device(s) control(s) the outflow rate of the injection fluid to a reservoir rock opposite said position/zone. The flow control device(s) is (are) disposed between an internal flow space (18) of the injection string (4) and the reservoir rock opposite said position/zone, and said device(s) is (are) hydraulically connected to at least one through-going pipe wall opening (28, 86) in the injection string (4), and to said reservoir rock. By using such flow control devices, the outflow profile of the injection fluid may be appropriately controlled along the injection string (4).
