Hohlladungsperforator mit InitialladungShaped charge perforator with initial charge

Hohll-adungsperforatoren werden für die Erforschung von ölführenden Gesteinsschichten und die Förderung von Erdöl in verschiedenen Formen und Größen verwendet. Sie bestehen meistens aus vollkommen gekapselten Sprengstoffladungen, die an einer dafür besonders dünn gehaltenen. Stelle mit Hilfe einer Sprengschnur initiiert werden. Bekannte Systerne enthalten einen einzigen Sprengstoff, z.B. Hexogen oder Oktogen,Hollow charge perforators are used for research into oil-carrying Rock strata and the extraction of petroleum used in various shapes and sizes. You insist mostly from completely encapsulated explosive charges, the one on a particularly thin one. Place with Can be initiated using a detonating cord. Known systems contain a single explosive, e.g. hexogen or octogen,

Die in den leisten Jahren immer weiter gesteigerten Anfor- '.· derungen an die Temperaturbeständigkeit (Bohrlochtiefe) dieser Systeme macht die Verwendung von Sprengstoffen sowohl bei den Perforatoren als auch bei den Sprengschnüren nötig, die bei ausreichender Temperaturbeständigkeit noch eine .genügende Sensibilität .besitzen, um ihre Funktion auch, unter, diesen erschwerten Bedingungen äü erfüllen.' Die
besten bisherigen Perforatoren- und Sprengschnurfüllungen bestehen aus Ilexon, das bis zu einer Temperatur von i8o°C praktisch verwendbar ist.
The demands on the temperature resistance (depth of the borehole) of these systems, which have increased over the last few years, make the use of explosives necessary for both the perforators and the detonating cords, which are sufficiently sensitive if they are sufficiently temperature-resistant. in order to also fulfill their function under these difficult conditions. ' the
The best previous perforator and detonating cord fillings are made of Ilexon, which can be used in practice up to a temperature of 180 ° C.

Für die Initialladung können Diaeide von Schwermetallen vorzugsweise Bleiacid oder Silberacid verwendet werden.

It should be made using the already known temperature-resistant, but initiation-insensitive secondary explosives, eg, hexanitrodiphenylamine, dipikrylosamide »Ικι shaped charge perforator and the use of already known temperature-resistant fillings of detonating cords, eg achieved according to the invention by arranging in the shaped charge perforator next to a main charge which is less sensitive to initiation than nitropenta, an initial charge made of an explosive which is more sensitive to detonation than nitropenta. Diaeids of heavy metals, preferably lead acid or silver acid, can be used for the initial charge.
