Steel wire throwing, straightening and hanging tool

Abstract

The invention relates to the technical field of hangers, in particular to a steel wire throwing, straightening and hanging tool. The tool comprises an upper connector, a mandrel, an outer barrel, slipassemblies, a straightening spring piece and a guide rod, the upper connector with the upper end located above the mandrel is fixedly installed at the outer side of the upper end of the mandrel, andthe lower portion of the upper connector is in a big-end-up circular truncated cone shape. The outer barrel with the upper end located at the outer side of the lower portion of the upper connector sleeves the outer side of the middle of the mandrel, at least two mounting openings communicated inside and outside are distributed at the outer side of the upper portion of the outer barrel at intervalsalong the circumference, and the slip assemblies capable of expanding outwards in the radial direction when the inner sides of the upper portions bear outward extrusion force are arranged in the mounting openings. The tool is reasonable and compact in structure and convenient to use, a guide column groove type rotary guide rail moves inwards by lifting and lowering the mandrel, the slip assemblies are engaged with the inner wall of a pipe column, and multi-position multi-time accurate hanging is completed; through the arrangement of a short groove, the change of the hanging position is realized; and by arranging a long groove, hanging of a set position is completed, and the tool has the advantages of being accurate, stable and high in throwing rate.

Description

technical field [0001] The invention relates to the technical field of hangers, and relates to a steel wire throwing and righting hanging tool. Background technique [0002] In the process of oil extraction, it is often necessary to use special testing instruments to measure parameters such as downhole pressure, temperature, and flow. When measuring oil and gas well parameters, logging vehicles or skid-mounted equipment are generally used to hang logging instruments in downhole tubing through steel wires. Some measurements take a long time, such as pressure recovery tests, which may take about 10 days to measure Finish. During this period, the logging vehicle or skid-mounted equipment, wellhead blowout prevention equipment, etc. have been occupied, resulting in low equipment utilization and greatly increased testing costs. In view of this situation, it is possible to design the reducing or seating sub when running the completion string, and put the instrument on the reduci...
