Abstract: A hydraulic anchor is coupled to a packer subassembly of a tool string. The hydraulic anchor, when actuated by fluid pressure, engages the surrounding wellbore, holding the tool string in place within the wellbore. A packer may then be actuated, held in position within the wellbore by the hydraulic anchor. In some embodiments, an inflatable packer may be held in the desired location by the hydraulic anchor. In some embodiments, a straddle packer assembly may be held in place by the hydraulic anchor. In some embodiments, a swellable packer may be held in place during the swelling process by the hydraulic anchor.

Abstract translation: 液压锚杆联接到工具串的封隔器子组件上。 当液压锚杆由流体压力致动时，液压锚固件与周围的井筒相接合，将工具柱保持在井眼内的适当位置。 然后可以通过液压锚杆将封隔器致动，保持在井筒内的适当位置。 在一些实施例中，可膨胀封隔器可通过液压锚固件保持在所需位置。 在一些实施例中，跨越式封隔器组件可以通过液压锚固件保持就位。 在一些实施例中，可膨胀封隔器可以在通过液压锚杆的膨胀过程期间保持就位。
