Specific implementation mode
Embodiment 1：
A kind of device of wellhead anti-falling, including anti-overflow pipe 1, enter well casing column 3, drilling floor surface 4, blowout preventer 5, surface pipe 2, rig floor
The bottom in face 4 is sequentially connected anti-overflow pipe 1, blowout preventer 5 and surface pipe 2 from the top down, enters well casing column 3 and passes through rig floor from the top down
Face 4 is connected to anti-overflow pipe 1, and anti-overflow pipe 1 is itself magnetic anti-overflow pipe or exciting magnet anti-overflow pipe.
Embodiment 2：
As shown in Figure 1, a kind of device of wellhead anti-falling, including anti-overflow pipe 1, enter well casing column 3, drilling floor surface 4, blowout preventer 5, surface layer
The bottom of casing 2, drilling floor surface 4 is sequentially connected anti-overflow pipe 1, blowout preventer 5 and surface pipe 2 from the top down, enter well casing column 3 on to
Under across drilling floor surface 4 be connected to anti-overflow pipe 1, anti-overflow pipe 1 be itself magnetic anti-overflow pipe or exciting magnet anti-overflow pipe.
The device of this wellhead anti-falling provided by the invention, when making a trip and creeping into, drilling tool tubing string passes through carrying magnetic
Anti-overflow pipe 1, when have ferromagnetism fragment, chip off-falling from rig floor enter anti-overflow pipe 1 when, can be pasted onto under magneticaction tubing string and
Between 1 inner surface of anti-overflow pipe, achieve the purpose that prevent well head from falling ferromagnetic material；The present invention has installation effectiveness high, works
Intensity is low, safe operation, simplicity；Operation principle is advanced simple, reduces workload and error；It does not influence to change existing equipment use
Effect and function.
Embodiment 3
As shown in Figures 2 and 3, on the basis of embodiment 2, itself magnetic anti-overflow pipe uses for anti-overflow tube body includes magnetic
Property or magnetic substance can be generated be made.Itself magnetic anti-overflow pipe uses comprising magnetism or can generate magnetic substance and be made.From
Body magnetic anti-overflow pipe shape shape consistent with the anti-overflow pipe size of onsite application is not limited, itself magnetic anti-overflow pipe has suitable
Intensity can directly substitute the anti-overflow pipe of onsite application；Ontology band is magnetic, and can be inhaled when magnetisable material is fallen inside it
It is attached to its inner surface, reaches purpose under preventing from falling into well.
The exciting magnet anti-overflow pipe includes tube body 6 and anti-overflow pipe outer wrapping 7 or can generate magnetic device, anti-overflow
Pipe outer wrapping 7 is connected in 6 outer wall of tube body or tube body 6 connects the device that can generate magnetism.The anti-overflow pipe outer wrapping 7 uses magnetic
Property material be made, anti-overflow pipe outer wrapping 7 or can generate magnetic device makes anti-overflow pipe band be magnetic, when have ferromagnetic object from
It can cause to be pasted onto 1 inner surface of anti-overflow pipe due to magneticaction when its internal whereabouts, playing prevents ferromagnetic material from falling purpose.
The magnetisable material of the anti-overflow tube body is ferromagnetic material, and the magnetic material of anti-overflow pipe outer wrapping 7 is ferromagnetism
Material.It is easy to fall ferromagnetism tool, fragment etc. in wellbore in existing construction, using anti-overflow pipe 1 made of ferromagnetic material
Trouble of lost tool in hole can preferably be prevented.
The tube body 6 and the connection type that can generate magnetic device are welding, stickup or winding.Connection type it is simple and
It is selected according to actual conditions, it is easy to operate, it is adaptable.
The magnetisable material of the anti-overflow pipe 1 is increased and decreased according to service condition.Due to unit type difference, drilling floor surface is caused
4 openings differ, and cause 1 size of anti-overflow pipe different；4 height of drilling floor surface differs with surface pipe or 2 size of wellhead blowout preventor group not
One, 1 length of anti-overflow pipe may be caused to differ, influence the magnetic anti-lost effect of anti-overflow pipe, must take into consideration appropriate increase and decrease magnetic when in use
Property substance, it is ensured that prevent ferromagnetic material from falling.
The anti-overflow pipe 1 is magnetic not to be glided in 1 inner wall of anti-overflow pipe as minimum magnetic mark with ensureing to clamp 1/2 ontological adsorption theory of tooth
It is accurate.The pincers tooth is Type B drill pipe tong, and pincers tooth falls object to be most common, and magnetic minimum should ensure that of anti-overflow pipe commonly uses pincers tooth
1/2 ontology can be adsorbed on inner wall and not glide as minimum magnetic standard.1 inner wall of anti-overflow pipe need to be carried out when routine use appropriate clear
Reason, reducing iron rust, drilling fluid mudcake etc. influences magnetic attracting factor.
The fixed magnetic substance or the device quantity that can generate magnetism are multiple and are equidistantly along the circumferential direction connected in pipe
In the middle part of the outer wall of body 6.1 field homogeneity of anti-overflow pipe increases magnetic attraction.
The operation principle of the present invention is that：
When making a trip and creeping into, drilling tool tubing string is by magnetic anti-overflow pipe 1, when having ferromagnetism fragment, chip off-falling from rig floor
When into anti-overflow pipe 1,1 inner surface of anti-overflow pipe can be pasted under magneticaction, reaches the mesh for preventing well head from falling ferromagnetic material
's.
