发明名称 Mechanical setting tool
摘要 A mechanical setting tool 10 has an inner mandrel 12, an upper sleeve member 20, and a lower sleeve member 22. The inner mandrel 12 is connected through a shear stud 14 to a conventional wireline packer 16. The upper sleeve 20 has setting slips 52 therein which are set by abutting the cone 66 mounted on top of the lower sleeve 22. The lower sleeve has a bottom shoulder 78 which engages an outer sleeve of the packer 18. Upward movement of the mandrel 12 sets the slips 52 and thereafter sets the slips on the packer. The mandrel 12 then shears shear stud 14 and separates from the packer and then disengages its slips 52 so that it can be retrieved from the casing 11.
