Abstract
The utility model discloses piano wire fishing devices in a kind of casing, belong to well workover specific purpose tool.The utility model includes shaft ontology, shaft top connection, shaft top connection, shaft ontology are circular tube shaped cavity structure, shaft top connection is equipped with external screw thread, shaft body bottom portion is inclined opening structure, shaft top connection, the intrinsic cavity perforation of shaft, screw clamp, steel wire crowfoot are welded on shaft ontology, screw clamp is that the circular helical structure on same axial line is arranged in shaft ontology, and steel wire crowfoot is circle hook structure.The utility model not only can carry out circulation flushing to the piano wire fallen into casing, but also can guarantee safe salvaging, and solving the problems, such as that piano wire is twined with oil sludge and sand in casing can not salvage when stirring when rinsing.
Description
Technical field
The utility model relates to well workover specific purpose tools, and in particular to piano wire fishing device in a kind of casing.
Background technique
During oil well, salvage fall into the piano wire in casing when, traditional fishing tool can not to oil
Silt particle twines the well steel wire that falls stirred and salvages when rinsing, and needs before salvaging independent tripping in washover pipe to falling after the flushing of well steel wire again
Tripping in fishing tool is salvaged；The problems such as independent running string rinses that there are flushing effects poor, tubing string is by card resistance, so as to cause
Construction efficiency is low in operation, and operating cost is high, and security risk is big.
Utility model content
The purpose of this utility model is to provide a kind of circulation flushing can either be carried out to the piano wire fallen into casing,
Piano wire fishing device in the casing salvaged safely may be implemented again.
The technical solution of the utility model is: piano wire fishing device in a kind of casing is beaten for the steel wire in casing
Fishing, including shaft ontology, shaft top connection, shaft top connection, shaft ontology are circular tube shaped cavity structure, and shaft top connection is equipped with
External screw thread, shaft body bottom portion are inclined opening structure, and the intrinsic cavity perforation of the cavity and shaft in shaft top connection connects, lance
Screw clamp, steel wire crowfoot are provided in bar body, screw clamp is circular helical structure, is arranged with shaft ontology same
On axial line, screw clamp is fixedly connected with shaft ontology, and the difference of the internal diameter of screw clamp outer diameter and casing is less than to be salvaged
The outer diameter of steel wire, steel wire crowfoot is circle hook structure, and is fixedly installed on shaft ontology.
Further technical solution, screw clamp are 2 weeks equidistant backpitch, screw clamp setting in shaft top connection and
Between steel wire crowfoot.
Further technical solution, steel wire crowfoot are 120 ° of right-handed screw groups of equidistantly distributed.
Further technical solution, shaft top connection, shaft ontology, screw clamp, steel wire crowfoot material be steel
Material.
The utility model has the beneficial effects that
1, the utility model is to process raw material with the common hollow rod in oil field and oil well pump, and this kind of raw material uses corrosion resistant
Erosion, the processing of intensity Hi-grade steel material, meet ongoing operations demand, on this basis Curve guide impeller, can be effectively reduced practical
Novel processing cost.
2, the structure design of the utility model is reasonable, thus guarantee live using effect, safety system simple with manufacturing process
The advantages of number height, long service life.
3, the utility model is in salvaging work progress, due to the cavity and the intrinsic cavity of shaft in shaft top connection
Perforation not only can carry out circulation flushing to the piano wire fallen into casing, but also can guarantee safe salvaging, solve well testing steel
Silk twines when stirring the problem of can not salvaging when rinsing with oil sludge and sand in casing, originally proposes effect with highly important to oil well drop
Meaning.
4, since the difference of screw clamp outer diameter and casing inner diameter is less than the outer diameter of salvaging steel wire in the utility model,
When transferring, above mentioning fishing string, it can avoid the occurrence of to fall on well steel wire and alter to fishing device top, cause fishing tool by card
Phenomenon.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model,
Wherein, 1, shaft ontology, 2, shaft top connection, 21, external screw thread, 3, screw clamp, 4, steel wire crowfoot.
Specific embodiment
Below by non-limiting embodiment, the utility model is further described, understands the utility model.
The utility model is piano wire fishing device in a kind of casing, for the steel wire salvaging in casing, such as Fig. 1, originally
Utility model includes shaft ontology 1, shaft top connection 2, and shaft top connection 2, shaft ontology 1 are circular tube shaped cavity structure, shaft
Top connection 2 is equipped with external screw thread 21, for being threadedly coupled fishing string.
1 bottom of shaft ontology is inclined opening structure, the cavity perforation in shaft top connection 2, shaft ontology 1, with fishing string
After connection, well-flushing water can be entered in well by the internal cavities in shaft top connection 2, shaft ontology 1.
Screw clamp 3, steel wire crowfoot 4 are provided on shaft ontology 1, screw clamp 3 is arranged in shaft top connection 2 and steel wire
Between crowfoot 4, the difference of 3 outer diameter of screw clamp and casing inner diameter is less than the outer diameter for salvaging steel wire.Screw clamp 3 is circular spiral
Structure is 2 weeks equidistant backpitch in figure, is arranged on same axial line with shaft ontology 1, screw clamp 3 and shaft ontology 1
Junction by being welded and fixed, steel wire crowfoot 4 is circle hook structure, and steel wire crowfoot 4 is 120 ° of right-handed screw groups of equidistantly distributed,
By being fixedly welded on shaft ontology 1.
The utility model is gathered materials on the spot, can according to casing specifications and models and fall well steel wire length design 1 size of shaft ontology,
The number of length and steel wire crowfoot 4 uses the common hollow rod in oil field and oil well pump to process raw material.Shaft top connection 2,
Shaft ontology 1, screw clamp 3, steel wire crowfoot 4 material be steel material.
In use, the utility model is threadedly coupled with fishing string, then by workover rig tripping in casing, visiting to falling
When well steel wire, the utility model can easily be inserted into disconnected fall in steel wire group under angle guidance and be rinsed, and screw clamp 3 can incite somebody to action
Single steel wire is pressed into group, facilitates salvaging.When mentioning on the utility model, the disconnected wire peg fallen is on recovery hook, due to the disconnected steel wire fallen
There is downward friction pendant power to be not to slip so the steel wire tangled can be firmly stuck on steel wire crowfoot 4；Well-flushing water is logical
Cross shaft top connection 2, the internal cavities in shaft ontology 1 enter in well, so as to overcome deficiency in the prior art, under
Enter into pipe sleeve to during falling salvaged this section of well out of well steel wire, the piano wire fallen into casing can both be recycled
It rinses, and can guarantee safe salvaging.
Since the difference of 3 outer diameter of screw clamp and casing inner diameter is less than the outer diameter of steel wire to be salvaged, decentralization is above mentioned and being beaten
When fishing out tubing string, it can avoid the occurrence of to fall on well steel wire and alter to fishing device top, lead to the phenomenon that fishing tool is by card.
