    • Apparatus is disclosed for securing a sonde to the inner wall of a well casing (3). The sonde (2) comprises a clamp (2) expandable from a contracted position to an expanded position in which the clamp can engage the inner wall. The securing apparatus comprises a member (5,6) for releasably engaging with the clamp (2) to hold the clamp in the contracted position; a spring (7) connected to the member such that when the spring is in a compressed state, the member is constrained into engagement with the clamp to hold the clamp in the contracted position; and a mechanism (8,9,10) for holding the spring (7) in its compressed state during a 10 first mode of operation and, in a second mode of operation, for releasing the spring (7) from its compressed state thus disengaging the member (5,6) from the clamp to permit the clamp to expand into its expanded position, the mechanism including a material (11) which in the first mode of operation, is in a solid state and, in the second mode of operation, is in a liquid state.
    • 公开了用于将探头固定到井套管(3)的内壁的装置。 探头(2)包括可从收缩位置扩展到扩展位置的夹具(2),在该位置夹具可与其接合内壁。 固定装置包括用于与夹具(2)可释放地接合以将夹具保持在收缩位置的构件(5,6) 连接到所述构件的弹簧(7),使得当所述弹簧处于压缩状态时,所述构件被限制为与所述夹具接合以将所述夹具保持在收缩位置; 以及用于在10次第一操作模式期间将弹簧(7)保持在其压缩状态并且在第二操作模式中用于将弹簧(7)从其压缩状态释放的机构(8,9,10),从而脱离 所述构件(5,6)从所述夹具移动以允许所述夹具膨胀到其展开位置,所述机构包括在所述第一操作模式中处于固态的材料(11),并且在所述第二操作模式 ,处于液态。

    • A method of using a seismic detector including four seismic sensors having axes which are in a substantially tetrahedral configuration, each of the sensors being in a respective signal channel, includes one or more of the following steps: combining outputs from the sensors to check that their polarities are correct; testing to ascertain if one of the sensors is not working and, if so, using the outputs from the other three sensors to obtain an indication of motion in three dimensions; if all four sensors are working, using their outputs to obtain an indication of motion in three dimensions on a least squares basis; checking that the outputs from the sensors are coherent; and checking the gains (or sensitivities) of the four channels.
    • 一种使用包括四个地震传感器的地震检测器的方法,所述地震传感器具有基本四面体结构的轴,每个传感器位于相应的信号通道中,包括一个或多个以下步骤:组合来自传感器的输出,以检查它们 极性是正确的 测试以确定其中一个传感器是否不工作,如果是,则使用其他三个传感器的输出来获得三维运动的指示; 如果所有四个传感器都在工作,则使用其输出在最小平方的基础上获得三维运动指示; 检查传感器的输出是否相干; 并检查四个通道的增益(或灵敏度)。
