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 Werkzeugen und Komponenten für den Offshore-Bereich und den Bergbau, insbes. für Bohranlagen.The invention relates to the use of a spray-compacted copper-nickel-manganese alloy as a material for the manufacture of tools and components for offshore and mining, especially for drilling rigs.

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 χ sollte dementsprechend 20.10-6 nicht überschreiten. (Dabei gibt χ nach der GI. M = µo . χ . H das Verhältnis der Magnetisierung M [ Vs / m 2] zur magnetischen Feldstärke H [ A / m] an, mit µo = 4 π . 10-7 = 1,256 . 10-6 [ Vs / Am] als magnetischer Feldkonstante.)
  • 2. Streckgrenze/Härte: Der Bohrstrang unterliegt hohen mechanischen und physikaiisch/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 Kupferlegierung 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 rods, screw connections, bolts, etc.) are required for high loads, which, among other things, have a high load capacity and must have very good corrosion properties and must not be ferromagnetic or explosions when they collide due to pyrophoric reactions of splinters spraying away or may start a fire.
    The following specific properties are required for the materials used in this application. Which includes:
  • 1. Magnetic properties: In order to meet the measurement requirements of the drill string in the area of compass measurement systems (measurement of the earth's magnetic field and the directional information derived from it), drill string components in this area must be non-magnetic, since in the presence of magnetic materials, incorrect measurements are made due to the influence of the magnetic field. Accordingly, the magnetic susceptibility χ should not exceed 20.10 -6 . (Here gibt according to the GI. M = µ o . χ. H the ratio of magnetization M [ V s / m 2 ] to the magnetic field strength H [ A / m ], with µ o = 4 π. 10 -7 = 1.256. 10 -6 [ V s / Am ] as magnetic field constant.)
  • 2. Yield strength / hardness: The drill string is subject to high mechanical and physical / chemical stresses. The individual strand elements are connected to one another by threaded connections. Because of the high forces that occur in the borehole, the individual string elements are screwed together with high torques. In order to avoid plastic deformation of the threads, the material must have a high yield strength. The surface of the drill string is stressed by abrasion and erosion. Wear is reduced to a minimum by the highest possible material hardness.
  • 3. Toughness: The exact load collectives are generally unknown. However, studies of damage that has occurred have shown that very high vibrating 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: The rock formations are mechanically broken up on the bottom of the borehole and pumped to the surface with a so-called drilling fluid. Increased temperature and the chemical or physico-chemical attack by the rinsing liquid require the materials used to be highly resistant to corrosion. In particular, the material must be resistant to stress corrosion cracking in media containing sulfur.
  • 5. Eating behavior: The screwing of the individual drill string elements under high torque must not lead to cold welding ("seizure"). For this reason, materials of a different type (e.g. steel with non-ferrous metal) should be connected to one another. In the case of threaded connections of drill string components made of austenitic, non-magnetizable steels, intermediate pieces made of a high-strength copper alloy are often screwed in 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.According to the state of the art, components and Tools made of copper materials, especially made of Cu-Be alloys, which combine these properties in a special way. As an example the copper-beryllium intermediate pieces, which are used for austenitic, non-magnetizable Drill collars can be 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 Anlagenausrüstern für die Offshore-Technik. Jegliche Kritikpunkte gilt es zu vermeiden. Now that environmental awareness in the population is increasing, consider aspects of environmental compatibility and health risks increasingly also in the center of interest of equipment suppliers for the Offshore technology. Any criticism 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 the possible health effects of dust and -Vapors that occur when materials containing materials are improperly processed can, there are therefore increasing demands for free materials posed.

    Der Erfindung liegt daher die Aufgabe zugrunde, einen Kupferwerkstoff zu finden, der das geforderte Eigenschaftsprofil ebenfalls möglichst weitgehend erfüllt, dabei aber Be-frei ist.The object of the invention is therefore to find a copper material, which also fulfills the required property profile as far as possible but is free.

    Die Aufgabe wird erfindungsgemäß durch die Verwendung einer sprühkompaktierten 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).The object is achieved by using a spray-compacted Copper-nickel-manganese alloy dissolved, which consists of 10 to 25% nickel, 10 to There is 25% manganese, the rest copper and usual impurities (the percentage refers to the weight).

    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 proposed loading-free composition not only meets all requirements but also have significant advantages in terms of availability the usual Cu-Be alloys can be achieved and by the production by means of spray compacting also a selectively better technological suitability is found, 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. 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 area of the electrical and electronic components known, the relatively expensive Cu-Be alloys to be replaced by cheaper copper-nickel-manganese alloys, the claimed use for a spray-compacted alloy Art is not known, however.

    Der Urformprozeß für den Kupferwerkstoff erfolgt durch Sprühkompaktieren (vgl. den sog. "OSPREY"-Prozeß beispielsweise nach den GB-PSen 1.379.261/1.599.392 oder EPS 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 (cf. the so-called "OSPREY" process, for example according to GB-PS 1,379,261 / 1,599,392 or EPS 0.225.732). As a preform, there are bolts that pass through typical thermoforming processes (pressing, rolling, forging) into semi-finished products (Rods, tubes, profiles, bushings) can be processed.

    Bevorzugte Ausführungsformen der Erfindung ergeben sich nach den Ansprüchen 2 bis 6.Preferred embodiments of the invention result from the claims 2 to 6.
