Druck in diese FormationPATENT ANSPRÜCHE : 1. Verfahren zur Gewinnung von Öl aus ölführenden Bodenformationen, wobei Öl unter Einwirkung von in mindestens eine Injektionssonde eingepresstem Dampf nach mindestens einer Produktionssonde ver- drängt undausdieserletzterengefördertwird, dadurch gekennzeichnet, dassmanvorderDurch- führung des Verdrängungsverfahrens Dampf in die Produktionssonde einpresst, die Dampfzufuhr abstellt, die Sonde öffnet, und daraus Öl fördert. Print in this pattern PATENT CLAIMS: 1. A method for extracting oil from oil-bearing soil formations, wherein oil is displaced under the action of steam pressed into at least one injection probe after at least one production probe and is conveyed from the latter, characterized in that before the displacement process is carried out, steam is injected into the production probe, which shuts off the steam supply The probe opens and oil pumps out of it. 2. Verfahren nachAnspruch l, dadurch gekennzeichnet, dass man die Vorbehandlung auch durch die Injektionssonde vornimmt. 2. The method according to claim l, characterized in that the pretreatment is also carried out through the injection probe. 3. Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass man die Vorbehand- lung (durch ein und dieselbe Sonde) beliebig oft wiederholt. 3. The method according to claim 1 or 2, characterized in that the pretreatment (by one and the same probe) is repeated as often as desired. 4. Verfahren nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass man während der Vorbehandlung zwischen dem Abschalten der Dampfzufuhr und dem Öffnen der Sonde (n) zur Förderung eine Rastperiode einschaltet. 4. The method according to any one of claims 1 to 3, characterized in that a rest period is switched on during the pretreatment between switching off the steam supply and opening the probe (s) for conveyance. 5. Verfahren nach den Ansprüchen 2 und 3, d a d u r c h g e k e n n z e i c h n e t, dass man die Dampf- zufuhrperiodc und die Förderperiode der Injektionssonde mit der Förderperiode bzw. der Dampfzufuhrperiode der Produktionssondc zusammenfallen lässt. 5. The method according to claims 2 and 3, d a d u r c h g e k e n n z e i c h n e t that the steam supply periodc and the funding period of the injection probe can coincide with the funding period or the steam supply period of the production probe. 6. Vorrichtung zur Durchführung des Verfahrens nach einem oder mehreren der Ansprüche l. bis 5, welche eine Dampferzeugungsanlage, Dampfleitungen von der Dampferzeugungsanlage zu der Formation, einen Sammelbehälter für Öl und Leitungen für Öl von der Formation zum Sammelbehälter umfasst, EMI3.1 sehene Dampfleitung als auch eine mit einem Ventil versehene Ölleitung führt. 6. Device for performing the method according to one or more of claims l. to 5, which comprises a steam generating plant, steam lines from the steam generating plant to the formation, a sump for oil and lines for oil from the formation to the sump, EMI3.1 See steam line as well as an oil line provided with a valve leads. 7. VorrichtungnachAnspruchC, dadurch gekennzeichnet, dass in denSonden die Ölleitung und die Dampfleitung durch eine gemeinsame Leitung gebildet werden. 7. Device according to claim C, characterized in that in the probes the oil line and the steam line are formed by a common line.
