Description
Technical field
The utility model relates to oil field development underground work technical field, particularly relates to one and to tackle all problems at once fishing tool.
Background technology
Along with the oil-gas field development time increases, part casing damage in oil-water well and the impact by down-hole geological condition, oil gas water well hole condition is deteriorated increasingly, part well seriously shake out and the accident such as trouble of lost tool in hole increasing, the salvaging of many regular junks has rich experience at present, and have developed a large amount of corresponding fishing tools.But the salvaging for irregularly shaped object is irregular to follow, also do not have corresponding fishing tool optional, fishing is very difficult, and scraps once process bad construction period growth and even this well of just easily causing.
Utility model content
For above-mentioned technical problem, the utility model has been designed and developed one and have been tackled all problems at once fishing tool, and object is to realize the salvaging to the irregular junk in down-hole, improves fishing success ratio, shortens construction period.
The technical scheme that the utility model provides is:
One is tackled all problems at once fishing tool, comprising:
Cylindrical shell;
Bailer grab, itself and described cylindrical shell are fixed, described bailer grab is made up of multiple grapple, one end of each grapple and the lower end of described cylindrical shell are fixed, the other end of each grapple bends inwards setting, bending angle is between 50 ~ 80 °, and the lower end that multiple grapple is evenly distributed on described cylindrical shell forms a nonocclusive accommodation space, and the kink that the opening of described accommodation space is multiple grapple is formed;
Wherein, each grapple is made by elastic wire.
Preferably, described tackles all problems at once in fishing tool, and the lower end of described cylindrical shell is provided with a connecting ring, and described connecting ring is threaded with described cylindrical shell lower end, described connecting ring periphery offers multiple through hole, and one end of described grapple is fixed through described through hole and described connecting ring.
Preferably, described tackles all problems at once in fishing tool, described connecting ring periphery is apart from described cylindrical shell lower end 1 ~ 2cm, and described connecting ring main body is threaded with described cylindrical shell lower end, and the grapple at least two through the through hole on described connecting ring periphery is welded to each other and is integrated.
Preferably, described tackles all problems at once in fishing tool, and described connecting ring lower end is also provided with a retainer ring, and described Fixing shrink ring is located at described bailer grab top, and is fixed on the top of described cylindrical shell by a connecting rod.
Preferably, described tackles all problems at once in fishing tool, and described connecting rod is scalable connecting rod, comprise bar in an outer bar and, described interior bar is set in described outer bar, and the lower end of described outer bar is fixed on described retainer ring, and upper end and the described cylindrical shell top of described interior bar removably connect.
Preferably, described tackles all problems at once in fishing tool, and described retainer ring is arranged in the mode that can slide up and down along described bailer grab under the effect of external force.
Described in the utility modelly tackle all problems at once in fishing tool, the lower end of described cylindrical shell is provided with a bailer grab be made up of multiple grapple, because each grapple is made by elastic wire, when bailer grab touches junk in well, the external world applies an active force straight down to bailer grab, and the kink of multiple grapple launches to surrounding, namely the opening of non-close accommodation space is opened, junk enters in non-close accommodation space, along with cylindrical shell is recovered to ground under the effect of external force, improves fishing success ratio.After trouble of lost tool in hole enters the non-close space of bailer grab, promoting connecting rod makes the retainer ring on bailer grab top slide into middle part, thus tightens multiple grapples of described bailer grab, makes bailer grab more firm to fixing of junk, avoid coming off suddenly, shorten construction period.
Accompanying drawing explanation
Fig. 1 is the axial cross-sectional views of fishing tool of tackling all problems at once described in the utility model;
Fig. 2 is the radial section schematic diagram of the bailer grab of fishing tool of tackling all problems at once described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to manual word to make those skilled in the art.
As depicted in figs. 1 and 2, the utility model provides one to tackle all problems at once fishing tool, comprising:
Cylindrical shell 1;
Bailer grab 2, itself and described cylindrical shell are fixed, described bailer grab is made up of multiple grapple 3, in the present embodiment be 10, one end of each grapple and the lower end of described cylindrical shell are fixed, and the other end of each grapple bends inwards setting, and bending angle is between 50 ~ 80 °, the lower end that multiple grapple is evenly distributed on described cylindrical shell forms a nonocclusive accommodation space 4, and the kink that the opening of described accommodation space is multiple grapple is formed;
Wherein, each grapple is made by elastic wire.
Described tackles all problems at once in fishing tool, the lower end of described cylindrical shell is provided with a connecting ring 5, described connecting ring is threaded with described cylindrical shell lower end, and described connecting ring periphery offers multiple through hole, and one end of described grapple is fixed through described through hole and described connecting ring.
Described tackles all problems at once in fishing tool, described connecting ring periphery is apart from described cylindrical shell lower end 1 ~ 2cm, described connecting ring main body is threaded with described cylindrical shell lower end, grapple at least two through the through hole on described connecting ring periphery is welded to each other and is integrated, can freely up and down slide in through-holes, be convenient to when bailer grab touches junk in well, junk enters in the non-close accommodation space of bailer grab smoothly.
Described tackles all problems at once in fishing tool, and described connecting ring lower end is also provided with a retainer ring 6, and described Fixing shrink ring is located at described bailer grab top, and is fixed on the top of described cylindrical shell by a connecting rod 7.
Described tackles all problems at once in fishing tool, described connecting rod is scalable connecting rod, and comprise bar 9 in an outer bar 8 and, described interior bar is set in described outer bar, the lower end of described outer bar is fixed on described retainer ring, and upper end and the described cylindrical shell top of described interior bar removably connect.
Described tackles all problems at once in fishing tool, and described retainer ring is arranged in the mode that can slide up and down along described bailer grab under the effect of external force, better to tighten bailer grab, and fixing junk wherein.
