摘要： A method for jarring allowing the operator to selectively control the jarring force while the tool is downhole and a powered bidirectional mechanical jar therefor, is disclosed. The jar includes a housing, an anvil fixed within the interior the housing, first and second hammers movably disposed within the housing at obverse sides of the anvil, first and second springs disposed to urge the hammers towards the anvil, and a rod with a radial catch that selectively engages and disengages the hammers so as move the hammers to compress the springs and thereafter release the hammers to be accelerated against the anvil. A actuator operates the catch. By controlling the movement of the rod, the spring compression and resultant jarring intensity can be controlled. A stroker tool may be provided to move the rod.

摘要： A downhole tool includes a tool body and a first anchoring device integrated with the tool body. The first anchoring device includes at least two linear actuators within and non-perpendicular to the tool body, each of the at least two linear actuators configured to move a corresponding contact pad between a retracted position and an anchor position. The first anchoring device also includes at least one guide component coupled to each contact pad to restrict movement of a corresponding contact pad to a predetermined path.

摘要： A downhole tool includes a tool body and an anchoring device integrated with the tool body. The anchoring device includes a contact pad that is at least partially external to the tool body, the contact pad having multiple stages with different thicknesses. The anchoring tool also includes a first linear actuator and a second linear actuator. The first linear actuator is configured to move the contact pad axially with respect to the tool body to align one of the multiple stages with the second linear actuator. The second linear actuator is configured to apply a radial force to the contact pad.

摘要： A multi-perforating assembly can include a housing containing a rotor. The rotor can be axially stroked by a multi-stroker tool. Upon axial movement, the rotor can cooperate with the housing to incrementally rotate. Axial movement of the rotor can cause a multi-perforating cartridge to radially pierce. Rotation of the rotor combined with piercing of the multi-perforating cartridge can enable multiple piercings to be easily and quickly performed in a single run. A multi-perforating cartridge can include a blade pivotally attached to a slider. The blade can be pulled past ports in a cartridge housing whereupon biasing springs can push the blade into the ports and a support pin can push the blade into piercing positions before pushing the blade into transitional positions, after which the blade can be biased into the subsequent port.
摘要翻译：多孔组件可包括容纳转子的壳体。转子可以通过多冲程器工具轴向调节。在轴向移动时，转子可以与外壳配合以逐渐旋转。转子的轴向运动可导致多孔筒径向穿透。转子的旋转与多穿孔筒的穿孔结合使得能够在单次运行中容易且快速地执行多个穿孔。多穿孔筒可以包括枢转地附接到滑块的刀片。刀片可以被拉动通过盒壳体中的端口，随后偏置弹簧可以将刀片推入端口，并且支撑销可以在将刀片推入过渡位置之前将刀片推入穿刺位置，之后刀片可以偏置到随后的港口。
