Abstract
The utility model provides a tool release device for an underground oil- producing well. The tool release device is used for putting tools into the oil-producing well from the ground and comprises a hanging body, a tool and a releaser, wherein the upper part of the hanging body is provided with oil pipe internal threads and a plurality of strip bodies are milled below the oil pipe internal threads, and the upper parts of the strip bodies are connected with one another and the lower parts of the strip bodies are not connected; the tool is suspended on a horizontal shoulder at the lower part inside the hanging body; the lower inner part of the hanging body takes a shape of a tapered round hole and the releaser is mounted below the tapered round hole of the lower inner part of the hanging body; the upper end of the releaser is conical and the conical end surface penetrates into the tapered round hole at the lower inner part of the hanging body; external threads are formed in the upper part of the hanging body; the releaser is sleeved with a releasing tube; internal threads in the upper part of the releasing tube and the external threads in the upper part of the hanging body are screwed together. According to the utility model, tools can be lifted to a well mouth and put into the well by an operation hoist, and that the tools are put into the well manually is not required. Therefore, the release of the tools is convenient and safe and relatively long and heavy tools can be put into the well.
Description
Technical field
The utility model belongs to oil well rig tool, is a kind of tool in oil well releasing device.
Background technology
Oil well on oil field, be on ground to drop-in tool in well in operation and manufacturing process, to oil well test, the operation such as obstruction.Existing downhole tool input method is manually instrument to be put into well head, then unclamps and allows instrument fall in well.This method workload is large, dangerous, limited because of people's strength, length, heavy instrument can not be put in well.For this reason, technician has developed tool in oil well releasing tool, as Chinese patent: 201020503238.3 < < downhole oil-producing tool releaser > >, need the artificial suspension body ability releasing tool of pressing, labor strength is large, because artificial strength is limited, the large instrument having cannot discharge, and also needing other power-equipment to coordinate could releasing tool.
Summary of the invention
The purpose of this utility model is to provide a kind of tool in oil well releasing device, makes its delivery tool convenience, safety, long heavier instrument can be rendered in well.
The purpose of this utility model is achieved in that and comprises suspension body, instrument, releaser, oil pipe internal thread is arranged at the top of suspension body, under the oil pipe internal thread of suspension body, milling is split into multiple bodies, each body top is connected, each body bottom does not connect, instrument is suspended on the horizontal shoulder of bottom in suspension body, inner under suspension body is taper circular hole, under suspension body, under interior tapered circular hole, releaser is installed, releaser upper end is conical, conical end face is goed deep under suspension body in interior tapered circular hole, external screw thread is established on the top of suspension body, releasing tube is sleeved on outside releaser, the external screw thread on the upper internal threaded of releasing tube and suspension body top screws.
The beneficial effects of the utility model are: during releasing tool, with pipe wrench, block releasing tube, rotate again suspension body, suspension body is walked downwards, each body that suspension body milling is split into expands outwardly, after just making instrument depart from, drop in well, therefore, the utility model delivery tool is convenient, safety, laborsaving, can alleviate workman's labour intensity.
