摘要： A downhole conveyance line cutter operable to be conveyed downhole within a wellbore along a conveyance line that conveys a tool string within the wellbore and then cut the conveyance line. The downhole conveyance line cutter may have a body defining an axial passage configured to accommodate the conveyance line therethrough such that the downhole tool can be conveyed downhole within the wellbore along the conveyance line until the downhole tool contacts the tool string. The downhole tool also comprises a clamping mechanism operable to connect the downhole tool to the conveyance line. The clamping mechanism comprises a clamping member pivotably connected with the body, as well as an actuator operable to pivot the clamping member to cause the clamping member to engage the conveyance line thereby connecting the downhole tool to the conveyance line such that the downhole tool can be retrieved out of the wellbore via the conveyance line after the downhole tool cuts the conveyance line.

摘要： A downhole tool mechanism for applying a driving force, such as a cutter tool for cutting a line captured within the tool, comprises a resiliently compressible member for storing a compressive force; a retaining device for maintaining storage of the compressive force until released; a trigger mechanism for releasing the compressive force when the trigger mechanism is activated. In one form the resiliently compressible member comprises a plurality of concentrically arranged spring washers each having a radial slot therein for receiving a line along the length of the resiliently compressible member. In the cutter form, there is a cutter arranged to cut the line when the trigger mechanism is activated, and the trigger mechanism is activated when the tool receives a shock force to one or both ends.
