Abstract
The utility model is related to a kind of drilling well non-threaded casing tube grippers, it is characterised in that：It is bound round surely by tube gripper box cupling, tube gripper, tube gripper trunnion, tube gripper locking strap, tube gripper retaining ring and sealing ring form, tube gripper locking strap is arranged in tube gripper binds round surely, the top of tube gripper locking strap is equipped with tube gripper box cupling, tube gripper retaining ring is equipped in tube gripper locking strap, upper and lower two sealing rings are equipped in tube gripper retaining ring.The utility model drilling well non-threaded casing tube gripper solves the problems such as wellbore construction landslide, leakage reality, necking down, chip off-falling, with wealthy drill repeated effect more preferably, greatly improves work efficiency, reduce drilling cost.
Description
Technical field
The utility model belongs to drilling equipment technical field, is to be directed to follow up with drilling rod using non-threaded casing and casing
Corollary apparatus, suitable for the drilling mode with casing drilling, more particularly to a kind of drilling well non-threaded casing tube gripper.
Background technology
At present, it is domestic it is traditional in the prior art with sleeve-like manner bore well use non-threaded casing with reduce drilling well into
This.But this drilling mode with casing is cannulated by work artificial after first drilling well, exists：Waste of manpower influences bit speed etc.
Problem.And jacket insertion depth does not reach requirement, and easily caves in drilling process, undergauge, leakage, and the drilling wells such as chip off-falling show
As causing drilling well difficult.
Invention content
The utility model overcomes above-mentioned defect, it is therefore an objective to for high working efficiency, reduce drilling cost, provide one
Kind drilling well non-threaded casing tube gripper.
The utility model drilling well non-threaded casing tube gripper content Description：
The utility model drilling well non-threaded casing tube gripper, it is characterised in that：Be bound round surely by tube gripper box cupling, tube gripper,
Tube gripper trunnion, tube gripper locking strap, tube gripper retaining ring and sealing ring composition, tube gripper locking strap are arranged on tube gripper and bind round surely
Interior, the top of tube gripper locking strap is equipped with tube gripper box cupling, is equipped with tube gripper retaining ring in tube gripper locking strap, is locked in tube gripper
Tight ring is equipped with upper and lower two sealing rings.
The utility model drilling well non-threaded casing tube gripper solves wellbore construction landslide, leakage reality, necking down, chip off-falling etc. and asks
Topic, with wealthy drill repeated effect more preferably, greatly improves work efficiency, reduces drilling cost.
Description of the drawings
Fig. 1 is drilling well non-threaded casing tube gripper structure diagram；
In figure：1 it is tube gripper box cupling, 2 is that tube gripper is bound round surely, 3 is tube gripper trunnion, 4 is tube gripper locking strap, 5 is folder
Pipe device retaining ring, 6 be casing, 7 be sealing ring.
Specific embodiment
The utility model drilling well non-threaded casing tube gripper is achieved in that be illustrated below in conjunction with the accompanying drawings.
See Fig. 1, drilling well non-threaded casing tube gripper, be by：Tube gripper box cupling 1, tube gripper bind round surely 2, tube gripper trunnion 3,
Tube gripper locking strap 4, tube gripper retaining ring 5 and sealing ring 7 form, and tube gripper locking strap 4 is arranged on tube gripper and binds round in 2 surely, folder
The top of pipe device locking strap 4 is equipped with tube gripper box cupling 1, is equipped with tube gripper retaining ring 5 in tube gripper locking strap 4, is locked in tube gripper
Tight ring 5 is equipped with upper and lower two sealing rings 7.
During work：Tube gripper box cupling 1 drives with power top and connects, and tube gripper retaining ring 5 is under the action of tube gripper locking strap 4
The casing 6 of non-threaded is clamped, and by two 7 upper-lower seals of sealing ring, is enclosed in the drilling fluid flowed in casing 6, makes it
On power top, drive row cinder notch excludes, and when connecing casing replacing 6, puts down 6 drilling machine of casing by tube gripper retaining ring 5 and stops boring, start to connect
Next casing completes casing replacing process.
The utility model drilling well non-threaded casing tube gripper solves wellbore construction landslide, leakage reality, necking down, chip off-falling etc. and asks
Topic, with wealthy drill repeated effect more preferably, greatly improves work efficiency, reduces drilling cost.
