Description
Gegenstand der vorliegenden Erfindung sind Einlagen für Hohlladungen aus kaltverpressten Pulvermetallmischungen, die beispielsweise im Bereich der öl- und gasfördernden Industrie zum Zweck von Tiefbohrlochsprengungen Verwendung finden.object In the present invention, liners for shaped charges are cold-pressed Pulvermetallmischungen, for example, in the field of oil and gas-promoting Industry for the purpose of deep hole blasting.
Für Hohlladungen,
die im Bereich der öl-
und gasfördernden
Industrie zum Zweck von Tiefbohrlochsprengungen Verwendung finden,
ist der Einsatz von Einlagen aus kaltverpressten Pulvermetallmischungen
Stand der Technik. Unter Pulvermetallmischungen sind dabei Mischungen
von Metallen und/oder Mischungen von Legierungen von Metallen in
Pulverform zu verstehen. Beim Kaltverpressen werden die Pulvermetallmischungen
durch Komprimieren unter ausreichend hohem Druck ohne zusätzliche
Wärmezufuhr
in die Endform verpresst, wie in
Die Pulvermetallmischungen die zur Herstellung der Einlagen verwendet werden, lassen sich in weiten Bereichen variieren. Eine Mischung kann beispielsweise 10 bis 30 Gew.-% eines weichen Metalls enthalten, das als Bindemittel dient, während der restliche Anteil der Mischung aus härteren Metallen bestehen kann. Als Bindemittel wird bei den meisten handelsüblichen Einlagen Blei verwendet. Denkbar sind auch andere Metalle wie beispielsweise Wismut, Silber, Gold, Zinn, Uran, Antimon, Zink, Kobalt oder Nickel. Der Rest der Mischung besteht häufig aus Schwermetallen wie Kupfer, Bronze und/oder Wolfram in unterschiedlichen Mischungsverhältnissen.The Powder metal blends used to make the inserts can be varied over a wide range. A mixture may for example contain 10 to 30 wt .-% of a soft metal, which serves as a binder while the remaining portion of the mixture may consist of harder metals. As a binder lead is used in most commercial deposits. Also conceivable are other metals such as bismuth, silver, Gold, tin, uranium, antimony, zinc, cobalt or nickel. The rest of Mixture is often from heavy metals such as copper, bronze and / or tungsten in different Mixing ratios.
Um
größere Eindringtiefen
zu erreichen, wird in der einschlägigen Literatur vorgeschlagen,
die Dichte des Einlagenmaterials so hoch wie möglich zu wählen. Unter ökonomischen
Aspekten bietet sich daher insbesondere Wolfram als Material für pulvermetallische
Hohlladungseinlagen an, wie in
Ein
Problem bei Einlagen aus Mischungen aus Wolfram und Blei stellt
die Bildung von „Slugs" dar. Darunter sind
Reststücke
des Jets zu verstehen, die die Durchschusskanäle nach dem Schuss verstopfen.
In WO 2000012858 A2 und
Einen weiteren Nachteil reiner Wolfram-Blei-Mischungen stellt der geringe Lochdurchmesser der Einschusslöcher dar. In der Förderung von Fluiden aus porösen, geologischen Formationen ist der Lochdurchmesser des Einschusskanals aber entscheidend für den hydraulischen Widerstand bei der Förderung. Ein großer Lochdurchmesser bei gleichzeitig hoher Eindringtiefe wird daher als vorteilhaft erachtet.a Another disadvantage of pure tungsten-lead mixtures is the low Hole diameter of the bullet holes In the promotion of Fluids of porous, geological formations is the hole diameter of the bullet channel but crucial for the hydraulic resistance in the promotion. A big hole diameter at the same time high penetration depth is therefore advantageous considered.
Aufgabe der vorliegenden Erfindung war die Bereitstellung von Einlagen für Hohlladungen, die einen großen Lochdurchmesser bei gleichzeitig hoher Eindringtiefe bewirken.task the present invention was the provision of inserts for shaped charges, the one big Hole diameter at the same time cause high penetration depth.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Hauptanspruches gelöst. Vorzugsweise Ausgestaltungen finden sich in den Unteransprüchen. Dabei wurde gefunden, dass der Zusatz von Leichtmetallpulvern, beispielsweise Aluminium- und/oder Titanpulver, zu Wolfram-Blei-Mischungen oder Wolfram-Kupfer/Bronze-Blei-Mischungen zu einer deutlichen Steigerung des Lochdurchmessers führt, ohne große Verluste bei der Eindringtiefe zu verursachen.According to the invention Problem solved by the features of the main claim. Preferably Embodiments can be found in the subclaims. It was found that the addition of light metal powders, such as aluminum and / or Titanium powder, tungsten-lead mixtures or tungsten-copper / bronze-lead mixtures leads to a significant increase in the hole diameter, without size To cause losses in the penetration depth.
Zusätzlich zu oder an Stelle von Wolfram können auch Tantal und/oder andere Schwermetalle und/oder deren Legierungen eingesetzt werden. Auch kann Wolfram bei Zusatz von Leichtmetallpulvern und höheren Anteilen von Blei in der Mischung ganz durch Bronze oder Kupfer oder ein Gemisch aus diesen ersetzt werden. Dabei sind Bronze und Kupfer in beliebigen Mischungsverhältnissen einsetzbar.In addition to or in place of tungsten also tantalum and / or other heavy metals and / or their alloys be used. Tungsten can also be added with the addition of light metal powders and higher Proportions of lead in the mix all by bronze or copper or a mixture of these are replaced. These are bronze and copper in any mixing ratios used.
