Verfahren zur Verbesserung von Sonden

Die Verwendung solcher künstlicher Füllkörper ermöglicht eine genaue Bestimmung der Durchflussquerschnitte in dem auf diese Weise künstlich geschaffenen Filterkörper und es können die Festigkeit, Kapillarität, Durchlässigkeit und andere physikalische Eigenschaften besser vorausbestimmt werden. Bei der Verwendung natürlicher Körner als Füllkörper ist die Durchlässigkeit der künstlich geschaffenen Zone nur durch Wahl der Körnergrösse der Füllkörper beeinflussbar.
Da das flüssige Kunstharz, beispielsweise ein Phenolformaldehyd-, ein Resorcin- oder ein Polyesterkunstharz, erst nach Einbringung des Füllmateriales in die Hohlräume in die Sonde eingeführt wird, wird eine Bindung von in der Sonde befindlichem Füllmaterial und damit eine Verstopfung der Sonde mit Sicherheit vermieden, und da weiters das zwischen den Füllkörpern befindliche noch nicht ausgehärtete, überschüssige Kunstharz anschliessend durch Einführung der Druckflüssigkeit aus den Hohlräumen entfernt wird, so dass lediglich ein Kunstharzfilm auf den Füllkörpern verbleibt, wird die gegenseitige Verankerung der Füllkörper mit Sicherheit gewährleistet.
PATENTANSPRÜCHE :
1. Verfahren zur Verbesserung von Sonden, dadurch gekennzeichnet, dass dem produktiven Horizont der Sonde ein das die Sonde im produktiven Horizont umgebende Material lösendes chemisches Agens, insbesondere eine hochkonzentrierte Säure mit gutem Tonlösungsvermögen, z. B. Essig-oder Flusssäure, zugeführt wird, worauf in die hiedurch geschaffenen Hohlräume mittels einer Trägerflüssigkeit, z. B. Wasser, Petroleum oder Rohöl, ein körniges Füllmaterial, z. B.
Quarzsand oder gekörntes Glas, unter Druck eingebracht wird, und dass hierauf ein flüssiges, unmittelbar vorher mit einem Härter versetztes Kunstharz, beispielsweise ein Phenolformaldehyd-, Resorcin- oder Polyesterkunstharz, zugeführt und das zwischen den Körnern befindliche überschüssige Kunstharz durch Zuführung einer Flüssigkeit von geringer Netzfähigkeit und Viskosität, wie Petroleum, Gasöl oder leichtes Rohöl, unter Druck verdrängt wird.

The use of such artificial filling bodies enables an exact determination of the flow cross-sections in the filter body artificially created in this way and the strength, capillarity, permeability and other physical properties can be better predicted. When using natural grains as fillers, the permeability of the artificially created zone can only be influenced by choosing the grain size of the fillers.
Since the liquid synthetic resin, for example a phenol-formaldehyde, a resorcinol or a polyester synthetic resin, is only introduced into the probe after the filling material has been introduced into the cavities, binding of the filling material in the probe and thus clogging of the probe is definitely avoided. and since the not yet cured, excess synthetic resin between the fillers is then removed from the cavities by introducing the pressure fluid so that only a synthetic resin film remains on the fillers, the mutual anchoring of the fillers is guaranteed.
PATENT CLAIMS:
1. A method for improving probes, characterized in that the productive horizon of the probe is a chemical agent which dissolves the material surrounding the probe in the productive horizon, in particular a highly concentrated acid with good clay-dissolving power, e.g. B. acetic or hydrofluoric acid is supplied, whereupon in the cavities created thereby by means of a carrier liquid, for. B. water, petroleum or crude oil, a granular filler material, e.g. B.
Quartz sand or granular glass is introduced under pressure, and that a liquid synthetic resin, for example a phenol-formaldehyde, resorcinol or polyester synthetic resin, to which a hardener has been added immediately beforehand, is added and the excess synthetic resin located between the grains is added by adding a liquid with low wetting properties and viscosity, such as petroleum, gas oil, or light crude oil, is displaced under pressure.
