Abstract

Die Erfindung beschreibt ein Verfahren zur Injektion eines Fluides in eine Erdöl-haltige Gesteins- oder Erdschicht mittels einer geeigneten Leitung, wobei die Leitung in die Gesteins- oder Erdschicht eingebracht wird, und das Fluid zum Zweck einer erhöhten Förderung von Erdöl aus der Erdöl-haltigen Gesteins- oder Erdschicht injiziert wird. Das Fluid wird über die beiden Leitungen 1 und 2 in die Erdöl-haltige Gesteins- oder Erdschicht injiziert. Beide Leitungen 1 und 2 sind ungefähr gleich weit von der Förderleitung 3 entfernt. Aus der Leitung 1 wird der Gasstrom G1 gepulst in die Erdöl-haltige Gesteins- oder Erdschicht injiziert. Aus der Leitung 2 wird der Gasstrom G2 ebenfalls gepulst in die Erdöl-haltige Gesteins- oder Erdschicht induziert. Dabei werden Pulslängen von ca. 20 min. verwendet. Der zeitliche Abstand zwischen zwei Pulsen einer Injektionsleitung beträgt ca. 1 Std. Die injizierten Gasmengen G1 und G2 sind dabei jeweils in der gleichen Größenordnung. Durch die Überlagerung der gerichteten und gepulsten Gasströme G1 und G2 bildet sich ein resultierender Gasstrom G3, der sich in Richtung der Förderleitung 3 bewegt. Somit wird durch die gerichteten und gepulsten Gasströme das Erdöl in Richtung der Förderleitung 3 getrieben. In dieser Ausgestaltung der Erfindung werden abwechselnd Stickstoff und Kohlendioxid injiziert, so dass die unterschiedlichen Eigenschaften beider Gase für die Erdölförderung genutzt werden können.

The invention describes a method for injecting a fluid into a petroleum-containing rock or soil layer by means of a suitable conduit, wherein the conduit is introduced into the rock or soil layer, and the fluid for the purpose of increased production of petroleum from the petroleum-containing Rock or soil layer is injected. The fluid is injected via the two lines 1 and 2 in the petroleum-containing rock or earth layer. Both lines 1 and 2 are approximately equidistant from the delivery line 3. From line 1, the gas stream G1 is pulsed injected into the petroleum-containing rock or soil layer. From the line 2, the gas stream G2 is also pulsed induced in the petroleum-containing rock or earth layer. Here are pulse lengths of about 20 min. used. The time interval between two pulses of an injection line is about 1 hour. The injected gas quantities G1 and G2 are in each case of the same order of magnitude. Due to the superimposition of the directed and pulsed gas flows G1 and G2, a resulting gas flow G3, which moves in the direction of the delivery line 3, is formed. Thus, the oil is driven in the direction of the delivery line 3 by the directional and pulsed gas streams. In this embodiment of the invention, nitrogen and carbon dioxide are alternately injected, so that the different properties of both gases can be used for crude oil production.
