Unless otherwise defined, all of technologies and scientific terms used here by the article and belong to the technical field of the application
The normally understood meaning of technical staff is identical.The term used in the description of the present application is intended merely to description tool herein
The purpose of the embodiment of body, it is not intended that in limitation the application.Term as used herein "and/or" includes one or more
The arbitrary and all combination of relevant Listed Items.
As shown in Figure 1, the application embodiment provides a kind of trouble of lost tool in hole fishing device, can include：Cylinder 1,
The lower end of the cylinder 1 is provided with opening 101, and the roof 100 of the cylinder 1 is provided with through-hole 102, the inner wall of the cylinder 1
Multiple first hooks 103 are provided with, multiple first hooks 103 tilt upward extension；It is threaded through the body of rod of the through-hole 102
2, so as to which the body of rod 2 is separated into the first rod segment 201 outside the cylinder 1 and positioned at institute by the roof 100 of the cylinder 1
The second rod segment 202 in cylinder 1 is stated, first rod segment 201 is used to be connected with fishing string, second rod segment 202
Multiple second hooks 203 are provided on side wall, multiple second hooks 203 tilt upward extension；The body of rod 2 can be described
It is moved in cylinder 1, so as to which multiple second hooks 203 can be extend out to through the opening 101 outside the cylinder 1.
In the present embodiment, the lower end of cylinder 1 can be provided with set milling head 104, and set milling head 104 is circumferentially spaced
There are multiple teeth 105.Set milling head 104 can play by junk surrounding impurities carry out set milling achieve the purpose that unfreezing, while cover milling head
104 high intensity, high rigidity are also beneficial to roll, be compacted junk, and taking junk progress piece cover into, improve and salvage effect.
In the present embodiment, the component that set milling head 104 can additionally be set, can be by being welded to connect in cylinder 1
Lower end.Alternatively, set milling head 104 can also be integrally formed with cylinder 1, you can be taken at the heat such as quenching with the lower end to cylinder 1
Science and engineering skill so that the hardness increase of the lower end of cylinder 1, so as to form the set milling head 104.
Further, the upper end of the first rod segment 201 can be connected with connector 3, the inner wall of connector 3 can be provided with for
The internal thread 301 that fishing string is connected, so as to fulfill the trouble of lost tool in hole fishing device and fishing string of the application embodiment
Be detachably connected, while downward active force can be applied to the body of rod 2 by fishing string, realize the second rod segment 202 from cylinder
It is stretched out in the lower ending opening 101 of body 1.
In order to reduce the resistance of the second rod segment 202 stretching, the lower end of the second rod segment 202 can be provided with tapered guiding
First 204, the area of section of seeker 204 is gradually reduced from top to bottom.In this way, when the second rod segment 202 moves down, seeker
204 can reduce resistance when the second rod segment 202 stretches out cylinder 1, and it can also be relatively easily inserted into trouble of lost tool in hole,
It is hooked up so as to fulfill to trouble of lost tool in hole.
During the trouble of lost tool in hole fishing device of the application embodiment is in lower going-into-well in order to prevent, the second rod segment
202 stretch out from cylinder 1, are cut to pieces to avoid before being arranged on the second hook 203 and internal surface of sleeve pipe of 202 outer wall of the second rod segment
It rubs, can bias be provided with spring 4 in one embodiment, between the body of rod 2 and cylinder 1, spring 4 can apply to cylinder 1
Downward elastic force.Effect according to power is mutual principle, and spring 4 will apply upward elastic force to the body of rod 2.In this way, in this Shen
During in trouble of lost tool in hole fishing device lower going-into-well please, the second rod segment 202 can remain the shape being housed in cylinder 1
State avoids the second hook 203 from scratching internal surface of sleeve pipe.
It can be that the first rod segment 201 is close to upper end that spring 4, which biases the concrete mode being arranged between the body of rod 2 and cylinder 1,
Side wall is provided with postive stop baffle 5, and spring 4 can be set in outside the first rod segment 201, and the upper end top is solid on postive stop baffle 5, lower end
Top is solid on the roof 100 of cylinder 1.
Further, to prevent cylinder 1 disconnected de- with connection occurs before the body of rod 2 so that between cylinder 1 and the body of rod 2 always
It can keep connecting, the outer wall of the body of rod 2 inwardly constriction can be formed with limited step 205, and the roof 100 of cylinder 1 corresponds to through-hole
102 lower surface can be pushed up admittedly on limited step 205, taken this, and cylinder 1 can be articulated on the body of rod 2, realizing 2 energy of the body of rod
While movement relative to cylinder 1, avoid the two and occur to connect disconnected take off.
In addition, in order to degree of raising trouble of lost tool in hole hook up and the accommodating efficiency preserved, multiple first hooks 103 and multiple the
The area of section of two hooks 203 is gradually reduced along its upward inclined direction, in this way, multiple first hooks 103 and multiple second are hung
Hook 203 can have sharp end, it is ensured that be salvaged into the trouble of lost tool in hole in cylinder 1 and will not break off relations easily when rising, carry
High fishing success ratio.
The trouble of lost tool in hole fishing device of the application embodiment sets multiple tilt upward to prolong by the inner wall in cylinder 1
The first hook 103 stretched, and wear the body of rod 2 in through-hole 102, and in the second rod segment 202 being located in cylinder 1 of the body of rod 2
Multiple second hooks 203 of outer wall setting, when being moved down in cylinder 1 so as to the body of rod 2, the second rod segment 202 can drive setting
203 lower ending openings 101 through cylinder 1 of multiple second hooks on its external wall stretch out, and hook up trouble of lost tool in hole, the subsequent body of rod 2 returns
It is reduced in cylinder 1, is housed so as to collect the trouble of lost tool in hole hooked up into cylinder 1, is arranged on the inner wall of cylinder 1
Multiple first hooks 103 be salvaged into the trouble of lost tool in hole in cylinder 1 and will not break off relations easily when may insure out, so as to reality
The efficient salvaging of existing junk.
It was verified that using the trouble of lost tool in hole fishing device of the application embodiment, following technique effect can be obtained：
1st, function and service.The trouble of lost tool in hole fishing device of the application embodiment overcomes common salvaging rope class and thin bar class
The shortcomings that junk instrumental function is single, can realize set milling unfreezing, compacting junk, it is whole the complex functions such as extract, save and apply
Work process, improves fishing success ratio.
2nd, it is at low cost.The trouble of lost tool in hole fishing device of the application embodiment can utilize original tool and discarded sleeve
Processing is transformed, purchase new tool is not needed to, also helps waste utilization and avoid the wasting of resources.
3rd, it is simple in structure.The trouble of lost tool in hole fishing device of the application embodiment is whole to think without complicated motion
Road is exactly that the tool of a variety of different function is carried out reasonable combination, to have the function that function and service.
4th, it is easy to operate.It is operation content basic in workover treatment to cover milling and crowfoot salvaging, and Ordinary Work work can be skilled
It grasps, the trouble of lost tool in hole fishing device of the application embodiment is to be combined into one the operating process of the two, without other complexity
Operating process, can skillfully be used with practical application by simply training.
For on the whole, the trouble of lost tool in hole fishing device of the application embodiment have it is at low cost, easy to operate, light and handy just
Prompt, advantages of simple structure and simple is widely used in oil field rope class, thin bar class fishing junk workover treatment.
