Abstract
The invention discloses a manufacturing technology of a deep-well drill collar, comprising the following technical flow of: preparing materials, aligning, drilling, thermally treating, checking mechanical property, turning, threading, checking and warehousing. The invention has the core technology that after the thermally treating flow is reasonably moved to the drilling flow, because a bar has lower hardness value when being not quenched, the drilling flow is easy to realize, and moreover, a cutter has low loss, thereby achieving the purposes of increasing effects and reducing consumption. In addition, the bar forms a hollow pipe structure through the drilling flow, and when being thermally treated, a hollow pipe can reduce energy consumption, is easy to quench through and creates conditions for increasing product quality. Because the drill collar belongs to the same type member with a drill rod, the invention is suitable for being used as a manufacturing technology of a deep-well drill rod.
Description
Technical field
The present invention relates to a kind of manufacture craft of shaft-like oil drilling and extracting equipment, specifically, the present invention relates to a kind of manufacture craft of deep-well drill collar.
Background technology
Drill collar is the key component that connects drill bit and drilling rod, and it directly carries the drilling well moment of torsion.Along with the raising of petroleum drilling and mining technology, the oil drilling degree of depth is more and more darker, and is therefore more and more higher to the specification requirement of drill collar.Prior art mainly realizes the high strength requirement with increasing thick diameter and heat treatment on the basis that material is determined.The common processes of making conventional drill collar in the industry is: get the raw materials ready → alignment → heat treatment → mechanical performance test → boring → turning → the system screw thread → the check warehouse-in.Although this technology is comparatively ripe, can realize the manufacturing of conventional drill collar, be not suitable for the manufacturing of deep-well drill collar.Its reason is the high strength alloy steel manufacturing of deep-well drill collar, and after heat treatment the material hardness value is very high, must increase the difficulty of follow-up machining.In addition, the more conventional drill collar diameter of deep-well drill collar diameter is slightly many, and the bar diameter of making the deep-well drilling rod is difficult for through hardening during large diameter solid bar heat treatment more than Φ 200mm, causes body of rod mechanical strength inhomogeneous and cause defective work.
Summary of the invention
The present invention is primarily aimed at the industry common processes and is not suitable for the problem that the deep-well drilling rod is made, propose a kind of method rationally, the synergy consumption reduction, and can significantly improve the deep-well drill collar manufacture craft of workmanship.This technology moves to heat treatment step after the machined, both has been convenient to machined, again easily through hardening.
The present invention is achieved through the following technical solutions technical goal.
Deep-well drill collar manufacture craft, its improvements are to follow these steps to implement:
(1) gets the raw materials ready;
(2) alignment;
(3) boring;
(4) heat treatment;
(5) mechanical performance test;
(6) turning;
(7) system screw thread;
(8) check warehouse-in.
Heat treatment step in the above-mentioned technology is a critical process, its hardening heat A
1Be controlled at 620 ℃ ± 5 ℃, A
2Be controlled at 800 ℃ ± 5 ℃, A
3Be controlled at 950 ℃～990 ℃, quenching velocity is 8～9HZ, and the back temperature A that quenches is controlled at 100 ℃～120 ℃, temperature T
1Be controlled at 630 ℃～650 ℃, T
2Be controlled at 665 ℃～675 ℃, T
3Be controlled at 675 ℃～685 ℃.
The present invention compared with prior art has following good effect:
1, heat treatment step moves to after the drilling operating, removes boring easily, also reduces the cutter loss;
2, bar forms tubular structure through boring, has both reduced energy consumption during hollow pipe heat treatment, again easily through hardening.
Description of drawings
Accompanying drawing is a technological process block-diagram of the present invention.
The specific embodiment
Below in conjunction with embodiment the present invention is further described.
Present embodiment is a kind of deep-well drill collar, long 9300mm, and diameter 165mm, its material is 4145H.Deep-well drill collar manufacture craft follows these steps to implement: at first get the raw materials ready by icon requirements, with the bar alignment, the processing of then holing, at this moment because of bar without quenching, the material hardness value is lower, favourable boring is processed, and has both improved the boring work efficiency, has also saved cutter.Bar forms tubular structure after holing, the hollow pipe blank is sent to done heat treatment in the stove, present embodiment hardening heat A
1Be controlled at 620 ℃ ± 5 ℃, A
2Be controlled at 800 ℃ ± 5 ℃, A
3Be controlled at 970 ℃ ± 10 ℃, quenching velocity is 8HZ, and the back temperature A that quenches is controlled at 110 ℃ ± 5 ℃, temperature T
1Be controlled at 640 ℃ ± 5 ℃, T
2Be controlled at 670 ℃ ± 5 ℃, T
3Be controlled at 680 ℃ ± 5 ℃.Carry out mechanical performance test after the heat treatment, promptly can be moved to after up to standard and do cylindrical turning on the lathe, then implement screw thread processing.Drill collar after the machined is tested, and the certified products warehouse-in is isolated defective work.
Core technology of the present invention is reasonably heat treatment to be moved to after the drilling operating, because bar is without quenching, its hardness number is lower, make boring realize easily, and the cutter loss is also little, realizes the target of synergy consumption reduction.In addition, bar forms tubular structure through boring, has both reduced energy consumption during hollow pipe heat treatment, and condition has been created in easily through hardening for improving the quality of products again.
Drill collar is same type member with drilling rod, and the present invention also is suitable as the technology of making the deep-well drilling rod.
