Abstract
The utility model relates to a downhole oil-producing tool releaser which is used for putting tools into a well from the ground. The releaser comprises a hanging body, tools and a release body, wherein the tools are hung at the lower part in the hanging body, and the part of the hanging body below a thread is provided with a plurality of bar bodies in a milling mode; the upper parts of the bar bodies are connected, and the lower parts of the bar bodies are not connected; the inner part below the hanging body is a tapered round hole; the release body is installed below the tapered round hole at the inner part below the hanging body; the upper end of the release body is cone-shaped; and the cone-shaped end face is embedded into the tapered round hole at the inner part below the hanging body. The mounted tools can be lifted to the mouth of a well and then put into the well by an operation lifting machine without labor power, thus the tools can be put into the well conveniently and safely, and longer and heavier tools can be put into the well.
Description
Technical field
The utility model belongs to the oil well rig tool, is a kind of oil recovery downhole tool release.
Background technology
Oil well on the oil field in operation and manufacturing process, be on ground in well drop-in tool, to oil well test, operation such as obstruction.Existing downhole tool input method is manually instrument to be put into well head, unclamps then to allow instrument fall in the well.This method workload is big, dangerous, and is limited because of people's strength, instrument long, that weigh can not be put in the well.
Summary of the invention
The purpose of this utility model provides a kind of oil recovery downhole tool release, makes its input instrument convenience, safety, can render in the well than long heavier instrument.
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 connect, and suspension body is inner down for the taper circular hole, and releaser is installed under the interior tapered circular hole under the suspension body, releaser upper end be a taper shape, and conical end face is goed deep under the suspension body in the interior tapered circular hole.
The beneficial effects of the utility model are: can be lifted on the well head mounted instrument and G.I.H by the operation elevator, not need manually instrument to be put into well head, therefore, the input instrument be convenient, safety, can render in the well than long heavier instrument.
Description of drawings
Accompanying drawing 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
1 couple of the utility model embodiment describes below in conjunction with accompanying drawing.Form by suspension body 1, instrument, releaser 3.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 connect, 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.Instrument 2 is lifted at well head and G.I.H by the operation elevator with mounted instrument 2 after being installed in the suspension body 1, does not need manually instrument 2 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.
