    • An apparatus for detecting movement downhole includes a first downhole component (106) having a sensor (114) coupled thereto and a second downhole component (102) positioned relative to the first downhole component (106). The sensor (114) generates a primary magnetic field that is imposed on the second downhole component (102) thereby generating an induced magnetic field that interacts with the primary magnetic field. Movement of the first downhole component (106) relative to the second downhole component (102) is detected by the sensor (114) by sensing a change in the induced magnetic field.
    • 一种用于检测井下运动的装置包括具有联接到其上的传感器(114)的第一井下部件(106)和相对于第一井下部件(106)定位的第二井下部件(102)。 传感器(114)产生施加在第二井下部件(102)上的主磁场,从而产生与主磁场相互作用的感应磁场。 传感器(114)通过感测感应磁场的变化来检测第一井下部件(106)相对于第二井下部件(102)的移动。

    • A wellbore isolation device comprises: at least a first material, wherein the first material: (A) is a metal or a metal alloy; and (B) is capable of at least partially dissolving when an electrically conductive path exists between the first material and a second material and at least a portion of the first and second materials are in contact with an electrolyte, wherein the second material: (i) is a metal or metal alloy; and (ii) has a greater anodic index than the first material. A method of removing the wellbore isolation device comprises: contacting or allowing the wellbore isolation device to come in contact with an electrolyte; and allowing at least a portion of the first material to dissolve.
    • 井筒隔离装置包括:至少第一材料,其中第一材料:(A)是金属或金属合金; 和(B)能够在第一材料和第二材料之间存在导电路径时至少部分地溶解,并且第一和第二材料的至少一部分与电解质接触,其中第二材料:(i )是金属或金属合金; 和(ii)具有比第一材料更大的阳极指数。 去除井筒隔离装置的方法包括:使井筒隔离装置接触或允许与电解液接触; 并允许至少一部分第一材料溶解。
