Description
Technical field
The present invention relates to the oil casing threaded in casing blasting treatment and the protection technique of surface spraying of complete thread, especially
It is a kind of multi-functional screwed pipe and application process with protective device.
Background technology
In each task of oil exploration and oil field development, drilling well plays a very important role.Find and confirmation contains
Hydrocarbon structure, obtain commercial oil, verify certified oil-containing（Gas）The hydrocarbon-bearing area and reserves of construction, obtain related oil field
Geologic information and exploitation data, finally crude oil is collected on ground from underground etc., none is not come complete by drilling well
Into.Drilling well is exploration and an important step of exploitation petroleum and natural gas resource, is the important hand of exploration and exploitation oil
Section.
After drilling well is drilled into target zone, protective casing, production casing is descended to carry out completion construction as needed, to the guarantor of tubing and casing
It is special important to seem oil and gas production enterprises for shield, particularly to the special stratum with heavy corrosion, using spraying inside and outside
The casing of anti-corrosion material is particularly important, and threaded casing is once sprayed in place, can greatly improve the anti-of casing
Rotten performance and processing efficiency.
At present usually using common tubing and casing thread protecting cap, when carrying out sprayed protection to casing threads, there are following to lack
Fall into：First, partial occlusion sleeve body, has the sleeve body of 100mm length since blocking for common helmet cannot thoroughly remove set
Booty on tube body, can not be sprayed-on corrosion-resistant coating；Second, common helmet and casing threads when being connected due to cone
Degree is consistent, and compact distance presses screw thread stress maximum area, optimal force design, last button screw thread of pipe screw thread and the first of helmet
Mouth screw thread cannot be at a fully engaged, and there are gap, the particle of ball blast is included between screw thread, is caused damage to screw thread, at ball blast particle
It is big to manage difficulty, influences work efficiency；Third, second of removing and spraying must be carried out, construction quality cannot ensure, construction effect
Rate is low, and cost is high, and labor intensity is big.
The content of the invention
The object of the present invention is to provide a kind of multi-functional screwed pipe and application process with protective device simple in structure,
It overcomes the shortcomings that current technology, and the object of the present invention is achieved like this, it includes sheath, casing, and the sheath is located at
The outside of casing.
The sheath does not have boring depth, directly holds end face level with both hands from screw initial thread, to small angle, makes sheath screw thread and casing spiral shell
The abundant all standing of line.
The taper of the sheath is arranged to 59-60, sheath first buckle screw thread and casing last buckle screw thread fully engage it is close
Envelope.
The compact distance of the sheath is -20mm, and the compact distance of casing coupling is 9mm, and sheath first buckles screw thread and casing most
Latter button screw thread fully engages sealing.
The application process of the present invention, one is to maintain tooth form, Ya Gao and the pitch of 1/2 oval casing threads, sufficiently protection
Casing threads is injury-free；Second, for preferably sealing protection casing threads, prevent ball blast steel sand etc. from entering in casing threads,
Sheath does not have boring depth, directly holds end face level with both hands from screw initial thread, to small angle, sheath screw thread is fully covered entirely with casing threads
Lid, effectively prevents the accumulation of ball blast particle；It is processed third, the taper of sheath is minimized 59-60 by calculating, function spiral shell
Line sheath first buckles screw thread and casing, and last buckles the fully ratcheting sealing of screw thread, prevents ball blast particle from entering in screw thread；Fourth, pair
Compact distance is adjusted, and the compact distance of sheath is -20mm, sheath first buckle screw thread and casing last to buckle screw thread fully ratcheting
Sealing, prevents ball blast particle from entering in screw thread.
Meaning of the present invention is that one is due to that sheath does not have boring depth, directly holds end face level with both hands from screw initial thread, to small
Angle, sheath screw thread and the abundant all standing of casing threads, effectively prevent the accumulation of ball blast particle；Two be due to that sheath first buckles screw thread
With last button fully ratcheting sealing of screw thread of casing, it is therefore prevented that ball blast particle enters in screw thread；Third, the compact distance of sheath for-
20mm, sheath first buckles screw thread and casing, and last is buckled screw thread and fully engages sealing, it is therefore prevented that ball blast particle enters in screw thread.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the multi-functional screwed pipe with protective device, 1, sheath 2, casing in figure.
Fig. 2 is a kind of assembling figure of the multi-functional screwed pipe with protective device, 1, sheath 2, casing in figure.
Embodiment
Embodiment 1, the present invention include sheath 1, casing 2, and the sheath 1 is located at the outside of casing 2.
Embodiment 2, the sheath boring depth are zero, directly hold end face level with both hands from screw initial thread, to small angle, make sheath screw thread
With the abundant all standing of 2 screw thread of casing.
Embodiment 3, the taper of the sheath 1 are arranged to 59-60, and sheath 1 first buckles screw thread and casing 2, and last buckles screw thread
Fully engagement sealing.
Embodiment 4, the compact distance of the sheath 1 are -20mm, and the compact distance of 2 box cupling of casing is 9mm, and sheath 1 first is buckled
Last button screw thread of screw thread and casing 2 fully engages sealing.
The application process of embodiment 5, the present invention, one is to maintain tooth form, Ya Gao and the pitch of 1/2 oval casing threads, fills
The protection sleeve pipe screw thread divided is injury-free；Second, for preferably sealing protection casing threads, prevent ball blast steel sand etc. from entering set
In pipe screw thread, sheath does not have boring depth, directly holds end face level with both hands from screw initial thread, to small angle, makes sheath screw thread and casing threads
Abundant all standing, effectively prevents the accumulation of ball blast particle；Added third, the taper of sheath is minimized 59-60 by calculating
Work, function recoil inserts first detains screw thread and casing, and last detains the fully ratcheting sealing of screw thread, prevents ball blast particle from entering screw thread
It is interior；Fourth, being adjusted to compact distance, the compact distance of sheath is -20mm, and sheath first buckles screw thread and casing, and last buckles spiral shell
The fully ratcheting sealing of line, prevents ball blast particle from entering in screw thread.
