Description
Technical field
It the utility model is related to oil field well instrument, specifically Clothoid type fishing tool.
Background technology
During oil drilling, because the reasons such as operational error, device damage cause bottom hole falling article can not continue to bore
Enter, it is necessary to which the corresponding fishing tool of tripping in, which pulls junk out, ensures that shaft bottom is cleaned.Fishing tool species is various at present, and conventional has one
Grab, with boring fishing cup, reacting cycle fishing tool, strong magnetic fishing tool etc..Traditional fishing tool during junk is salvaged all
In the presence of certain specific aim and limitation, such as strong magnetic fishing tool can not be implemented to salvage, tackle all problems at once for being not easy magnetized junk
Instrument, because the factors such as grasping teeth closure shaft bottom flatness cause salvaging efficiency low, object is salvaged with fishing cup is bored in work progress
Size and dimension is limited, and reacting cycle fishing tool is undesirable for the larger object salvaging effect of density, and above-mentioned instrument can not
The construction of lower curved section is well adapted to, causes the multiple salvaging DeGrain occurred in construction, uses milling time and effort consuming instead, hold
Other undergrounds complexity is easily caused, greatly increases cost input and the labor intensity of worker.
Utility model content
The purpose of this utility model is to provide Clothoid type fishing tool, can improve junk of the hole deviation more than 30 ° of well sections
Efficiency is salvaged, the junk species that can be salvaged is more complete, relatively low to the magnetic, density, shape need of junk, overcomes above-mentioned deposit
The problem of, reduce and salvage number, reduce the labor intensity of worker, prevent secondary accident or complicated occur.
In order to reach above-mentioned purpose, the utility model employs following technical scheme, Clothoid type fishing tool, including dipper
Cylinder, baffle plate, the dipper cylinder lower semisection open up radial opening, and the left-hand end of the radial opening is connected with baffle plate left-hand end,
The baffle plate is arc, and the right-hand end of baffle plate is involved in the right-hand end of the inside, i.e. baffle plate of above-mentioned radial opening right-hand end dipper cylinder
A rotary-cutting type is formed between the right-hand end of radial opening and salvages entrance.
The dipper cylinder body bottom sets cylinder bottom, and the baffle plate lower end is also connected on a bottom, on the cylinder bottom
It is evenly equipped with through hole.
Guide shoe is installed on the cylinder bottom, the guide shoe is located at the bottom that rotary-cutting type salvages entrance.
The rotary-cutting type salvages entrance and is provided with guide plate, and the guide plate is 30 degree tilting, and guide plate bottom is closer to rotation
Cut is salvaged on the outside of entrance, and inlet inside is salvaged in guide plate upper end closer to rotary-cutting type, and the guide plate bottom connects with cylinder bottom
Connect.
The dipper cylinder inboard wall and baffle plate are internally provided with strong magnetic stripe, are connect in the dipper cylinder upper end connection
Head.
Compared to prior art, the utility model has the advantages that：
In instrument tripping in pit shaft, turn clockwise fishing tool, be piled up in shaft bottom or the lower borehole wall junk can in guide shoe and
Through guide plate or fallen directly under the disturbance of opening cylinder in fishing socket cavity, fishing tool continues to rotate into cavity
Junk slides along dipper inwall, and when dipper opening is towards the lower borehole wall, baffle plate can block junk, prevent it from being opened from dipper
Dropped out at mouthful, so repeatedly, dipper can pull whole junks out substantially by salvaging to the lower borehole wall and shaft bottom, no matter junk material
Whether rule can be dragged for quickly obtains for matter, density size, shape, reached the purpose in cleaning shaft bottom, can be greatly reduced salvaging number,
Subtract reform through forced labor fatigue resistance, save drilling period, reduce operating cost.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model Clothoid type fishing tool；
Fig. 2 is Fig. 1 cross-sectional views.
In figure：Top connection 1, dipper cylinder 2, strong magnetic stripe 3, cylinder bottom 4, baffle plate 5, guide plate 6, guide shoe 7.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing is only to refer to
With purposes of discussion, not it is used for being any limitation as the utility model.
As shown in Figure 1-2, Clothoid type fishing tool, including dipper cylinder 2, baffle plate 5, the dipper cylinder lower semisection open up
Radial opening, the left-hand end of the radial opening are connected with baffle plate left-hand end, and the baffle plate is arc, and the right-hand end of baffle plate is involved in above-mentioned
The inside of radial opening right-hand end dipper cylinder, i.e., a rotary-cut is formed between the right-hand end of baffle plate and the right-hand end of radial opening
Formula salvages entrance.The dipper cylinder body bottom sets cylinder bottom 4, and the baffle plate lower end is also connected on a bottom, the cylinder bottom
Cover and be evenly equipped with through hole.Guide shoe 7 is installed on the cylinder bottom, the guide shoe is located at the bottom that rotary-cutting type salvages entrance.The rotation
Cut salvages entrance and is provided with guide plate 6, and the guide plate is tilting, and guide plate bottom is salvaged on the outside of entrance closer to rotary-cutting type,
