Abstract

A method for the manufacture of tools and components for the offshore field and the mining industry, in particular, for drilling installations, using a spray formed Cu-Ni-Mn alloy of 10 to 25% Ni, 10 to 25% Mn, the remainder being copper and common impurities. Due to the favorable characteristics of the combination, the alloy is suitable as a replacement material for Be-containing copper materials.

Description

Die Erfindung betrifft die Verwendung einer sprühkompaktierten Kupfer-Nickel-Mangan-Legierung als Werkstoff zur Herstellung von Bohrstrangkomponenten.The invention relates to the use of a spray-compacted copper-nickel-manganese alloy as a material for the production of Drillstring.

In der Offshore-Technik werden für hohe Beanspruchungen mechanische Komponenten (wie etwa Bohrgestänge, Verschraubungen, Bolzen, etc.) verlangt, die u. a. hohe Belastbarkeit aufweisen und sehr gute Korrosionseigenschaften haben müssen sowie weder ferromagnetisch sein dürfen noch beim Aufeinanderprallen durch pyrophore Reaktionen wegspritzender Splitter Explosionen oder Feuer auslösen dürfen.
Für die in diesem Einsatzgebiet verwendeten Werkstoffe werden folgende, spezifische Eigenschaften gefordert. Hierzu zählen:

  • 1. Magnetische Eigenschaften: Um meßtechnische Anforderungen des Bohrstrangs im Bereich von Kompaßmeßsystemen zu erfüllen (Messung des Erdmagnetfelds und der daraus ableitbaren Richtungsinformation) müssen Bohrstrangkomponenten in diesem Bereich unmagnetisch sein, da in Anwesenheit von magnetischen Werkstoffen Fehlmessungen durch Beeinflussung des Magnetfeldes erfolgen. Die magnetische Suszeptibilität X sollte dementsprechend 20 . 10-6 nicht überschreiten. (Dabei gibt χ nach der GI. M = µo . X . H das Verhältnis der Magnetisierung M [ Vs / m 2] zur magnetischen Feldstärke H [ A / m] an, mit µo = 4π . 10-7 = 1,256 . 10-6 [ Vs / Am] als magnetischer Feldkonstante.)
  • 2. Streckgrenze/Härte: Der Bohrstrang unterliegt hohen mechanischen und physikalisch/chemischen Beanspruchungen. Die einzelnen Strangelemente werden durch Gewindeverbindungen miteinander verbunden. Wegen der hohen Kräfte, die im Bohrloch auftreten, werden die einzelnen Strangelemente unter Aufbringung hoher Drehmomente miteinander verschraubt. Um plastische Verformungen der Gewinde zu vermeiden, muß der Werkstoff eine hohe Streckgrenze haben.Die Bohrstrangoberflächen werden durch Abrasion und Erosion beansprucht. Der Verschleiß wird durch eine möglichst hohe Materialhärte auf ein Minimum reduziert.
  • 3. Zähigkeit: Die genauen Belastungskollektive sind in der Regel unbekannt. Untersuchungen an aufgetretenen Schäden haben jedoch gezeigt, daß sehr hohe schwingende aber auch schlagartige Belastungen auftreten können. Die Zähigkeit der eingesetzten Werkstoffe spielt daher für das sichere Funktionieren eine entscheidende Rolle. Die Zähigkeit der eingesetzten Kupferiegierung sollte deshalb für ein Festigkeitsniveau maximiert und möglichst gleichmäßig über den Querschnitt sein.
  • 4. Korrosionsbeständigkeit: Auf der Sohle des Bohrlochs werden die Felsformationen mechanisch zertrümmert und mit einer sogenannten Bohrspülung an die Oberfläche gepumpt. Erhöhte Temperatur und der chemische bzw. physikalisch-chemische Angriff durch die Spülflüssigkeit erfordern eine hohe Korrosionsbeständigkeit der verwendeten Werkstoffe. Insbesondere muß der Werkstoff in schwefelhaltigen Medien resistent gegen Spannungsrißkorrosion sein.
  • 5. Freßverhalten: Die Verschraubung der einzelnen Bohrstrangelemente unter hohem Drehmoment darf zu keiner Kaltverschweißung ("Fressen") führen. Daher sollten möglichst artfremde Materialien (z. B. Stahl mit NE-Metall) miteinander verbunden werden.Bei Gewindeverbindungen von Bohrstrangkomponenten aus austenitischen, nichtmagnetisierbaren Stählen werden deshalb oftmals Zwischenstücke aus einer hochfesten Kupferlegierung dazwischengeschraubt. Als geeigneter Kupferwerkstoff wurde bisher beispielsweise Kupfer-Beryllium (UNS C 17200) eingesetzt.
    • In offshore technology, mechanical components (such as drill pipes, fittings, bolts, etc.) are required for high loads, which must have high load-bearing capacity and very good corrosion properties and must not be ferromagnetic or explosive due to pyrophoric reactions of splash splinters or cause fire.
    For the materials used in this application, the following specific properties are required. Which includes:
  • 1. Magnetic properties: In order to meet the metrological requirements of the drill string in the field of Kompaßmeßsystemen (measurement of the earth's magnetic field and derived therefrom directional information) drill string components in this area must be non-magnetic, since in the presence of magnetic materials made incorrect measurements by influencing the magnetic field. The magnetic susceptibility X should accordingly be 20. Do not exceed 10 -6 . (There are χ after the GI. M = μ o . X. H the ratio of magnetization M [ Vs / m 2 ] to the magnetic field strength H [ A / m ], with μ o = 4π. 10 -7 = 1.256. 10 -6 [ Vs / Am ] as the magnetic field constant.)
  • 2. Yield / Hardness: The drill string is subject to high mechanical and physical / chemical stresses. The individual strand elements are connected to each other by threaded connections. Because of the high forces that occur in the borehole, the individual strand elements are screwed together applying high torques. In order to avoid plastic deformations of the threads, the material must have a high yield strength. The drill string surfaces are subject to abrasion and erosion. The wear is reduced to a minimum by the highest possible material hardness.
  • 3. Toughness: The exact load collectives are usually unknown. Investigations of damage occurred, however, have shown that very high swinging but also sudden loads can occur. The toughness of the materials used therefore plays a decisive role in the safe functioning. The toughness of the copper alloy used should therefore be maximized for a strength level and be as uniform as possible over the cross section.
  • 4. Corrosion resistance: On the bottom of the borehole, the rock formations are mechanically shattered and pumped to the surface with a so-called drilling fluid. Increased temperature and chemical or physical-chemical attack by the rinsing liquid require high corrosion resistance of the materials used. In particular, the material in sulphurous media must be resistant to stress corrosion cracking.
  • 5. Eating behavior: The screwing of the individual drill string elements under high torque must not lead to cold welding ("seizing"). Therefore, as far as possible foreign materials (eg steel with non-ferrous metal) should be connected to each other. For threaded connections of drill string components made of austenitic, non-magnetizable steels therefore often intermediate pieces of a high-strength copper alloy are screwed between. For example, copper beryllium (UNS C 17200) has been used as a suitable copper material.

    • Für diese Anforderungen werden nach dem Stand der Technik Komponenten und Werkzeuge aus Kupferwerkstoffen, insbes. aus Cu-Be-Legierungen eingesetzt, die diese Eigenschaften in besonderer Weise auf sich vereinen. Als Beispiel gelten hierfür die Kupfer-Beryllium-Zwischenstücke, die bei austenitischen, nichtmagnetisierbaren Schwerstangen (sog. "drill collars") verwendet werden.For these requirements, the prior art components and Tools of copper materials, in particular of Cu-Be alloys used, the combine these qualities in a special way. As an example For this purpose, the copper-beryllium spacers, the austenitic, non-magnetizable Collars (so-called "drill collars") are used.

    Nachdem nun das Umweltbewußtsein in der Bevölkerung immer stärker wird, rücken Gesichtspunkte der Umweltverträglichkeit und Gesundheitsgefährdung zunehmend auch in das Zentrum des Interesses von Anlagenausrüstem für die Offshöre-Technik. Jegliche Kritikpunkte gilt es zu vermeiden. Now that the environmental consciousness in the population is getting stronger, consider aspects of environmental compatibility and health hazards increasingly also in the center of interest of Anlagenausrüstem for the Hear offs technology. Any criticisms should be avoided.

    Wegen möglicher gesundheitsgefährdender Wirkungen von Be-Stäuben und -Dämpfen, die bei unsachgemäßer Bearbeitung Be-haltiger Werkstoffe auftreten können, werden daher zunehmend Forderungen nach Be-freien Werkstoffen gestellt.Because of possible harmful effects of Be-dusts and Vapors that occur in case of improper handling of materials containing materials Therefore, demands for non-porous materials are increasingly being made.

    Aus der Druckschrift US 2,234,552 ist eine Kupfer-Mangan-Nickel-Legierung bekannt, die als Ersatz für Eisenlegierungen in vielen Bereichen ihren Einsatz findet. Des Weiteren ist aus der Druckschrift DE 40 06 410 A1 ein Halbzeug aus Kupfer oder einer Kupferlegierung mit einem Kohlenstoffzusatz bekannt, dessen Rohling mittels dem Sprühkompaktierverfahren hergestellt ist.From the document US 2,234,552 a copper-manganese-nickel alloy is known, which is used as a replacement for iron alloys in many areas. Of Furthermore, from the document DE 40 06 410 A1 a semifinished product made of copper or a copper alloy with a carbon additive known, the blank by means of produced by the spray-compacting process.

    Der Erfindung liegt daher die Aufgabe zugrunde, eine neue Verwendung des Kupferwerkstoffes zu finden, der das geforderte Eigenschaftsprofil ebenfalls möglichst weitgehend erfüllt, dabei aber Be-frei ist.The invention is therefore based on the object to find a new use of the copper material, the the required property profile also as far as possible fulfilled, but it Be-free.

    Die Aufgabe wird erfindungsgemäß durch die Verwendung einer mittels Sprühkompaktieren hergestellten Kupfer-Nickel-Mangan-Legierung gelöst, die aus 10 bis 25 % Nickel, 10 bis 25 % Mangan, Rest Kupfer und üblichen Verunreinigungen, besteht (die Prozentangabe bezieht sich auf das Gewicht), als Werkstoff zur Herstellung von Bohrstrangkomponenten.The object is inventively by the use of a spray compacting dissolved copper-nickel-manganese alloy, consisting of 10 to 25% nickel, 10 to 25% Manganese, the rest of copper and common impurities, consists (the percentage refers to the weight), as a material for manufacturing of drill string components.

    Es hat sich nun überraschend herausgestellt, daß mit Cu-Ni-Mn-Legierungen der vorgeschlagenen Be-freien Zusammensetzung nicht nur alle Anforderungen erfüllt werden können, sondern auch beträchtliche Vorteile in der Verfügbarkeit gegenüber den gebräuchlichen Cu-Be-Legierungen erzielt werden und durch die Herstellung mittels Sprühkompaktierens auch eine selektiv bessere technologische Eignung gefunden wird, insbes. werden die Anforderungen an Bohrstrangkomponenten gemäß API (American Petroleum Institute)-Specification 7 ("Specification for Rotary Drill Stem Elements") 38. Ed., April 1, 1994, erfüllt.It has now surprisingly been found that with Cu-Ni-Mn alloys of proposed Be-free composition not only meets all requirements but also offers considerable advantages in terms of availability the conventional Cu-Be alloys are achieved and by the production by means of spray compacting also a selectively better technological suitability In particular, the requirements for drill string components according to API (American Petroleum Institute) Specification 7 ("Specification for Rotary Drill Stem Elements ") 38th Ed., April 1, 1994.

    Es sind zwar Kupfer-Nickel-Mangan-Legierungen als solche bereits bekannt (vgl. beispielsweise US-PS 2.234.552/DEAN) und es ist beispielsweise auch im Bereich der elektrischen und elektronischen Bauteile bekannt, die relativ teuren Cu-Be-Legierungen durch preiswertere Kupfer-Nickel-Mangan-Legierungen zu ersetzen, der beanspruchte Verwendungszweck für eine sprühkompaktierte Legierung dieser Art ist allerdings nicht vorbekannt. Although copper-nickel-manganese alloys are already known as such (cf. For example, US-PS 2,234,552 / DEAN) and it is for example also in the field the electrical and electronic components known, the relatively expensive Cu-Be alloys by replacing cheaper copper-nickel-manganese alloys, the claimed use for a spray-compacted alloy of this type is not known.

    Der Urformprozeß für den Kupferwerkstoff erfolgt durch Sprühkompaktieren (vgl. den sog. "OSPREY"-Prozeß beispielsweise nach den GB-A- 1.379.261/1.599.392 oder EP-A- 0.225.732). Als Vorform bieten sich Bolzen an, die durch typische Warmformverfahren (Pressen, Walzen, Schmieden) zu Halbzeugfabrikaten (Stangen, Rohren, Profilen, Buchsen) verarbeitet werden.The primary molding process for the copper material is carried out by spray compacting (see. the so-called "OSPREY" process, for example, according to GB-A-1,379,261 / 1,599,392 or EP-A-0,225,732). As a preform offer themselves to bolt through typical thermoforming processes (pressing, rolling, forging) to semi-finished products (Rods, tubes, profiles, bushings) are processed.
