    • A multi-string well has an electric submersible pump (ESP) that can be removed without killing the well. A slotted liner is sealingly secured externally to casing and internally to a guide string that remains in the wellbore when the ESP is removed. A ported sub is part of the guide string and a concentric screen that can have instruments that moves relatively to the guide string can selectively allow flow in an annulus between them and to the ported sub or that annulus between the guide and concentric strings can be blocked off by manipulation of the concentric string to close the ported sub. With the lower portion of the well now blocked off, the wellhead can be removed so that the ESP can come out with the production string. The device has particular application to steam assisted gravity drainage (SAGD) systems as well as other downhole applications.
    • 多串井具有可以在不杀死井的情况下被移除的电潜泵(ESP)。 一个开槽衬套密封地固定在套管的外部,并在内部被固定到当ESP被移除时留在井眼中的导向柱。 移动的子是引导弦的一部分,并且可以具有相对于引导弦线移动的乐器的同心屏幕可以选择性地允许在它们之间的环形空间和移动的子空间中流动,或者可以阻止导向和同心弦线之间的环形空间 通过操纵同心弦来关闭移动子。 当井的下部被堵住时,可以拆下井口,以便ESP能够与生产线一起出来。 该设备特别适用于蒸汽辅助重力排水(SAGD)系统以及其他井下应用。

    • A system and method for utilizing a surface located oscillator (15) to generate seismic signals at a downhole location. The system includes a vibratory source (15) for generating axial vibrational energy in a tubular string (40) anchored in the borehole (55) at a suitable location. The vibratory source may be operated at a predetermined frequency or may generate a swept frequency signal. The axial vibrations are transmitted through the tubular string (40) and impart a seismic signal through the anchor (50) to the formation. In different configurations, the system imparts broadband seismic signals into the formation. Sensors (20, 21, 22, 45) are mounted on the vibratory source and downhole anchor for monitoring the system operation. Seismic receivers (70a, 70n, 80a, 80n, 90a, 90n) are deployed on the surface, in offset wells, or in the source well. Signals from the receivers are transmitted to a control unit (25). The control unit utilizes the sensor and receiver signals to control the operation of the vibratory source.
    • 一种用于利用表面定位振荡器(15)在井下位置产生地震信号的系统和方法。 该系统包括振动源(15),用于在合适的位置锚固在钻孔(55)中的管状串(40)中产生轴向振动能。 振动源可以以预定频率操作或者可以产生扫频信号。 轴向振动通过管柱(40)传递,并通过锚(50)将地震信号传递给地层。 在不同的配置中,系统将宽带地震信号输入地层。 传感器(20,21,22,45)安装在振动源和井下锚上,用于监测系统操作。 地震接收器(70a,70n,80a,80n,90a,90n)部署在表面,偏移井或源井中。 来自接收器的信号被发送到控制单元(25)。 控制单元利用传感器和接收器信号来控制振动源的操作。
