Abstract
The utility model relates to a down-hole tool release device, which comprises a suspension body, a tool and a releaser; the tool is suspended at the lower part within the suspension body, a plurality of strips is milled under the screw thread of the suspension body, the upper parts of the strips are connected with each other, and the lower parts are not connected; the lower part in the suspension body is a conical round hole, under which the releaser is arranged, the upper end of the releaser is a cone, whose end face is arranged deep into the conical round hole of the suspension body; the tool can be raised up to the well mouth and sank into the well through a hoist so that the utility model is free from people placing tool into the well, therefore, the placement of tools are convenient and safe, even the heavy tool can be placed into the well.
Description
Technical field
The utility model relates to a kind of oilfield apparatus for work, particularly a kind of downhole tool release.
Background technology
At present, the oil field in operation and manufacturing process, be in well drop-in tool, to oil well test, operation such as obstruction.General downhole tool input method is manually instrument to be put into well head, unclamps then to allow instrument fall in the well.This method exists workload big, uneasy congruent factor, and, because people's strength is limited, the instrument heavy than band andgudgeon can not be put in the well.
Summary of the invention
The purpose of this utility model provides a kind of downhole tool releasing device, makes its input instrument convenient, safe and reliable, long heavier instrument can be rendered in the well.
The purpose of this utility model is achieved in that by suspension body, instrument, releaser to be formed, instrument is suspended on bottom in the suspension body, mill under the suspension body screw thread and be split into a plurality of bodies, each bar body top links to each other, each bar body bottom does not link to each other, and the bottom is the taper circular hole in the suspension body, under the lower taper circular hole releaser is installed in the suspension body, the releaser upper end is conical, and conical end face is goed deep in the interior lower taper circular hole of suspension body.
The beneficial effects of the utility model are: adopt the operation elevator to be promoted on the well head mounted instrument and direct G.I.H, do not need manually instrument to be put into well head, therefore, the input instrument is convenient, safety, can render in the well than long heavier instrument, reduce labor strength greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is suspension body among the figure, and 2 is instrument, and 3 is releaser
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing,, form by suspension body 1, instrument 2 releasers 3 referring to accompanying drawing 1.Instrument 2 is suspended on bottom in the suspension body 1, mill under suspension body 1 screw thread and be split into a plurality of bodies, each bar body top links to each other, each bar body bottom does not link to each other, 1 time inside of suspension body is the taper circular hole, releaser 3 is installed under 1 time interior tapered circular hole of suspension body, and releaser 3 upper ends are conical, and conical end face is goed deep in 1 time interior tapered circular hole of suspension body.After instrument 2 is installed in the suspension body 1, promotes face by operation mounted instrument 2 is lifted at well head and G.I.H, do not need manually instrument 5 to be put into well head.The conical surface of releaser 3 struts suspension body 1 lower bar body under the weight effect, instrument 2 is discharged the back drop in the well.It is convenient, safe and reliable that this utility model has the input instrument, can render in the well than long heavier instrument, greatly reduces working strength of workers.
Claims (2)
