Description
Technical field
The present invention relates to a kind of short flow process flexibility drilling rod production equipment and production technology thereof, specifically is to remedy the deficiency of present drill-rod wire production technology and the drilling rod production technology of inventing, and satisfies the production of drill-rod wire, API product certification and API system certification.Can use the new drilling rod processing of manufacturing enterprise, be particularly suitable for the production of high standard grade of steel (E75, X95, G105, S135).
Background technology
Current, along with the increase of world market to the oil demand amount, market constantly proposes new requirement to the quality and the range of application of drilling rod, and production high-quality, high value added product also increases rapidly.Capability Requirement to the steel pipe process equipment is also more and more higher.On the other hand, API (American Petroleum Institute) standard was carried out a reexamination at least in per 5 years, is revised, reaffirms or cancel.Each drilling rod manufacturing enterprise and subsidiary factory thereof guarantee the stability of drilling rod properties of product in enormous quantities in order to obtain the API authentication, constantly its processing technology and equipment are improved, and obtain the stable share in drilling rod market in the hope of its product.
Modern serial drilling rod adopts the most general jumping-up+friction welding drilling rod.The joint design of modern serial drilling rod is that interior outer face contacts the form of structure of (Double Tops) simultaneously, can not only guarantee reliable sealing, and can bear bigger curved power and torsion.The body of rod of drilling rod adopts the API of American Petroleum Institute standard tubing to make and process ultrasonic testing/ ultrasonic examination check, joint adopts high-quality alloy steel to form by the high precision numerical control machined into, the joint screw thread is partly handled through gas nitriding, the computerized control welding quality of every friction welding seam, the heat treatment after numerically controlled Medium frequency induction unit is used to weld.Make joint have wear-resisting, intensity is high, the characteristics of good toughness, the body of rod has the characteristics of intensity height, good springiness.By the two ends of the jumping-up technology thickening body of rod, the wall thickness of weld is 1.5～1.9 times of body of rod wall thickness, has improved the intensity of commissure greatly, has thoroughly solved the easily broken problem in simple friction welding drill stem welding seam place.
According to the use experience in oil field, the inefficacy of drilling rod is mainly reflected in weld seam and interior two positions of crassitude intermediate belt.Aspect the safety that improves weld seam, each big drilling rod factory mainly is the safety factor that improves weld seam by friction welding method and suitable weld seam Technology for Heating Processing both at home and abroad at present.Connect and weld seam processing state-of-the-art according to petroleum drill pipe friction, in conjunction with of the requirement of API standard to the oil drill rocker weld properties, and the industry standard of contrast domestic petroleum natural gas, oil drill rocker has been carried out the weld properties statistics, analyze the weldquality of oil drill rocker.Improve the safety factor of weld seam, improving friction welding and weld seam Technology for Heating Processing is the new direction of current oil drill rocker development.
At present generally adopt manual grinding or facility machine tool to process to the preliminary treatment before the friction welding, the surface quality poor controllability of solder side directly has influence on the quality of back friction welding.The heat treated type of cooling tradition of weld seam is the compressed air cooling, generally adopts single manual the processing, and efficient is low, the technology beat is slow, and heat treated quality instability.Inner and outer welding after heat treatment is handled and is adopted manual mill traditionally, the size Control low precision, and surfaces externally and internally quality instability, and near weld seam, have iron filings, there is hidden danger of quality in follow-up check.Pressure test and weld inspection generally are applicable to the API standard of legacy version, and along with the modification of API standard and the variation of market demands, equipment can not satisfy new requirement on ability.

Drilling rod of the present invention: 1. drilling rod specification limit:
2. drilling rod grade of steel: E75, X95, G105, S135; 3. production capacity satisfies: 38 pieces/hour; 4. weld seam position treated length :≤200mm; 5. drilling rod becomes mouthful welding seam part site surface roughness Ra≤3.2.
Effect of the present invention is:
(1) the thickening end face preliminary treatment before the friction welding (FW) in the relatively more existing drilling rod production technology uses special purpose machine tool that pipe end is carried out planar end surface and inside and outside chamfered edge. It is characterized in that pretreated steel pipe upset end can touch the mark: the perpendicularity on pipe end surface (with respect to tubular axis)≤0.5mm/m, chamfered edge scope: 10mm 〉=C 〉=2mm, surface roughness is higher than Ra≤6.3. For stable welding provides favourable condition.
(2) compare conventional drill weld seam heat treatment mode, the type of cooling changes into forces quick water-cooled, and the pressure of cooling water brought up to 2.5MPa, water temperature is normal temperature, use the turbid circulating water in the industrial system both can, simultaneously carry out water-cooled in inside, the outside of body commissure, the highest cooling velocity can reach 100 ℃/s, than traditional pressure-air cooling Speed improving 2 times. Meanwhile increase the quantity of heat treatment station, improve auxiliary feeding equipment, can realize processing in groups 6 steel pipes at every turn. Can improve productive temp by improving, eliminate the bottleneck of production line, the whole working ability that improves. See Fig. 1 sequence number 5 places. Can obtain high tenacity, the hardness that is fit to cutting, the tissue of high-wearing feature by heat treatment, more adapt to the adverse circumstances such as rock stratum probing and high-pressure slurry stream.
(3) weld seam manual grinding during relatively existing drilling rod is produced, surface quality instability, outward appearance are plain, and pressure test and the stable of comprehensive test of postorder impacted. Weld seam finish turning lathe is adopted in weld seam fine finishining, but weld seam position treated length reaches 200mm most, and the machining accuracy surface roughness in inside and outside hole is higher than Ra≤6.3, cylindrical tolerance: Dv+0 〉=Dv 〉=Dv-1, endoporus tolerance: dv+0 〉=dv 〉=dv-2.

(5) increase the comprehensive test zone, pressure test, weld seam are beaten the operations such as hardness, magnetic powder inspection, ultrasonic examination and comprehensively arrived together. According to the requirement realization flexible configuration of different clients to product. Carry out the intensity of pressure test weld seam with pressure testing machine, according to different grade of steels and wall thickness, apply different pressure in the commissure, whether the Materials Yield Limit of check commissure reaches requirement. Hardometer is that the face of weld after the heat treatment is beaten hardness, if can not reach the requirement of corresponding grade of steel, then is considered as defective work. The magnetic powder inspection butt welded seam carries out transverse defect check, and the degree of depth of its defective should be less than 5% of thickness of steel pipe, otherwise is defective. Longitudinal defect and the lamination defect of ultrasonic wave butt welded seam are tested, and its defective is less than the aperture of 1.6mm diameter, otherwise are defective. Equipment is seen weld seam pressure Apparatus for Bending at low-temp 10, magnetic powder inspection device 11, ultrasonic flaw detecting device 12, the Hardness Surveillance device 13 among the figure.
(6) conventional production lines is relatively produced radical per year and can be reached 60,000, pipe diameter scope and exist
