Description
Verfahren zur Sekundärförderung von Erdöl durch Fluten Gegenstand eines noch nicht zum Stande der Technik gehörenden Vorschlages ist ein Verfahren zur Sekundärförderung von Erdöl durch Fluten, das dadurch gekennzeichnet ist, daß Salze der Celluloseäthercarbonsäuren oder Celluloseäthersulfosäuren und/ oder Stärkeäthercarbonsäuren oder Stärkeäthersulfosäuren und/oder Alginsäuren im Flutungsmittel verwendet werden. Vorteilhaft werden die vorgenannten Substanzen in Wasser oder in wäßrigen Salzlösungen als Flutungsmittel angewendet. Eine Steigerung der Wirkung soll unter Umständen durch Zusatz oberflächenaktiver Substanzen erreicht werden.Process for the secondary production of petroleum by flooding subject One suggestion that is not yet part of the state of the art is a method for secondary production of petroleum by flooding, which is characterized in that Salts of cellulose ether carboxylic acids or cellulose ether sulfonic acids and / or starch ether carboxylic acids or starch ether sulfonic acids and / or alginic acids are used in the flooding agent. The abovementioned substances are advantageous in water or in aqueous salt solutions used as a flooding agent. An increase in the effect should be possible under certain circumstances can be achieved by adding surface-active substances.
Bei weiterer Bearbeitung dieses Erfindungsgegenstandes wurde nun gefunden, d.aß sich für die Zwecke der Sekundärförderung von Erdöl durch Fluten mit gleich gutem Erfolg und in gleicher Weise an Stelle der im erwähnten Vorschlag genannten Salze Oxyalkyläther der Celiulose oder Johannisbrotkernmehl oder Äther des Johannisbrotkernmehls verwenden lassen. Vorteile können sich auch ergeben, wenn man die Oxyalkyläther der Cellulose oder Johannisbrotkernmehl oder Äther des Johannisbrotkermnehls in Kombination mit den in dem Hauptpatent genannten Substanzen anwendet.With further processing of this subject matter of the invention it has now been found d.ass for the purposes of the secondary production of petroleum by floods with the same good success and in the same way in place of those mentioned in the proposal mentioned Salts oxyalkyl ether of cellulose or locust bean gum or ether of locust bean gum let use. Benefits can also result from using the oxyalkyl ethers the cellulose or locust bean gum or the ether of the locust bean gum in Combination with the substances mentioned in the main patent applies.
Besonders vorteilhaft lassen sich Produkte verwenden, die sich in Wasser oder Salzlösungen klar und ohne Abscheidung von Fasern oder Duellkörpern lösen, da diese geeignet sind, das Gestein zu verstopfen und somit die Flutung zu verhindern. Die für das Flutungsmittel anzuwendende Menge dieser Stoffe beträgt im allgemeinen 1 bis 10 g/1, und zwar sowohl bei Anwendung rein wäßriger als auch salzhaltiger Lösungen.Products that can be used in Water or salt solutions clear and without separation of fibers or dueling bodies solve, as these are capable of clogging the rock and thus the flooding impede. The amount of these substances to be used for the flooding agent is generally 1 to 10 g / l, both when using purely aqueous solutions saline solutions.
Die Anwendung der erfindungsgemäß zu gebrauchenden Substanzen findet unter den gleichen Bedingungen des genannten Vorschlages statt. Die folgenden Beispiele dienen zur Erläuterung dieser Erfindung.The substances to be used according to the invention are used takes place under the same conditions of the proposal mentioned. The following examples serve to illustrate this invention.
Es wurden jeweils 233 kg Ölsand, der 54 1 entsprechend 47 k g Erdöl
enthielt, 1 Stunde geflutet. Zur Anwendung kam eine Oxyäthylcellulose bzw. ein Johannisbrotkernmehläther,
wie dieser beispielsweise in dem Handelsprodukt »Diagum« vorliegt, sowie auch Joh
annisbrotkernmehl. Beispiel 1
