    • A fluid injection device (38) for deployment in a well-bore to control injection of fluid into an oil reservoir, wherein the well-bore has an outer pipe (16) and an inner tube (14) which extends within the outer pipe and is connected at one end to a pressurized fluid supply above the ground. The device includes a control valve arrangement comprising: an inlet (42) for receiving the fluid from the inner tube; an outlet (56) for outputting the fluid outside the inner tube; an inlet valve (44) in a fluid path between the inlet and the outlet; and an actuator (50) associated with the inlet valve which is controllable to switch the inlet valve between its open and closed configurations, such that when the inlet valve is open, the fluid flows from the inner tube, via the inlet, fluid path and outlet to outside the inner tube. A method of controlling injection of fluid into an oil reservoir from a well-bore using such a device is also provided.
    • 一种用于展开在井眼中以控制将流体注入储油器的流体注入装置(38),其中井筒具有在外管内延伸的外管(16)和内管(14), 在一端连接到地面以上的加压流体源。 该装置包括控制阀装置,包括:用于从内管接收流体的入口(42) 用于将流体输出到内管外部的出口(56) 入口阀(44)在入口和出口之间的流体路径中; 以及与所述入口阀相关联的致动器(50),其可控制以在其打开和关闭构造之间切换所述入口阀,使得当所述入口阀打开时,所述流体经由所述入口流体路径从所述内管流动, 出口到内管外。 还提供了一种使用这种装置从井眼将流体注入储油器的方法。

    • An unflapped envelope (60) is fed, with its crease line trailing, along a path (42) from an envelope feeder and between the rollers of a reversibly driveable roller pair (43), for onward transfer to, for example, an insertion station. When the crease line reaches a predetermined point in front of the roller pair (43), the drive is reversed and the envelope with the crease line leading directed along a flapper path, including a deflecting surface 46; to a flapping chamber or zone (47), at least until the flap (61) is engageable by a flapper blade (44;44a). The drive is then reversed again and the envelope driven back along the flapper path, a flap opening surface (49) of a flapper blade (44) or a pair of flapper blade elements (44a), causing the flap (61) to be stripped from the body of the envelope (60) as it exits the flapping zone, and proceeds to the insertion station.
    • 沿着从信封进给器的路径(42)和可逆驱动的辊对(43)的辊之间沿着路径(42)将未折叠的信封(60)以其折痕线延伸,用于向前传送到例如插入站 。 当折痕线到达辊对(43)前面的预定点时,驱动器反转,并且带有折痕线的包络线沿着挡板路径引导,包括偏转表面46; 至少在挡板(61)可由挡板叶片(44; 44a)接合之前至震动室或区域(47)。 然后驱动器被再次反向,并且信封沿着挡板路径被驱回,挡板叶片(44)的翼片开口表面(49)或一对挡板叶片元件(44a),导致翼片(61)被剥离 从信封(60)的主体离开拍打区域时,进入插入台。
