Patentirt im Deutschen Reiche vom 31. Januar 1889 ab.Patented in the German Empire on January 31, 1889.
Bekanntlich zeigt sich bei den üblichen Bohrlöchern zur Gewinnung von Petroleum aus ölführenden Gesteinschichten oft schon nach kurzer Zeit eine bedeutende Abnahme in der Menge des mittelst Pumpen heraufbeförderten Petroleums.As is well known, it shows up in the usual boreholes for the extraction of petroleum from oil-bearing rock strata often a significant decrease in the amount of petroleum carried up by pumps.
Während man diese Erscheinung bisher immer der Erschöpfung des vorhandenen Rohöles zuschrieb, habe ich gefunden, dafs die Ursache- vielmehr in der Erkaltung der Gesteinschichten zunächst um die Bohrlochsohle und Bohrlochwände durch eindringende kalte Luft und einfliefsendes kaltes Tagwasser zu erblicken sei. Dieses Erkalten der Gesteinschichten hat zur Folge, dafs das Paraffin erstarrt, und an die zuerst gebildete dünne Paraffinschicht legen sich bei fortgesetztem Pumpen Gesteinpartikelchen an, so dafs die den Zuflufs verlegende Schicht rasch anwächst.While this phenomenon has always been the exhaustion of the available crude oil I have found that the cause is rather the cooling of the rock layers first around the bottom of the borehole and borehole walls by penetrating cold air and inflowing cold day water be seen. This cooling of the rock layers has the consequence that the paraffin solidifies, and with continued pumping, rock particles attach to the first thin layer of paraffin, so that the The layer laying the tributary grows rapidly.
Vorliegender Erfindung gemäfs beugt man nun der Bildung der Paraffinkruste und dadurch verursachten Verringerung des Ertrages dadurch vor, dafs man die Bohrlochsohle und Bohrlochwände erwärmt.According to the present invention, one now prevents the formation of the paraffin crust and thereby caused reduction of the yield by the fact that one the bottom of the borehole and Borehole walls heated.
Als Mittel für diesen Zweck können Dampf oder heifses Wasser dienen, welche man durch eine nach abwärts auf die Bohrlochsohle und wieder hinaufführende Leitung circuliren lä'fst, oder erhitzte Körper, welche mit Hülfe von Drahtseilen oder Ketten in das Bohrloch eingeführt werden, oder endlich auch durch das Durchleiten eines elektrischen Stromes erhitzte Leiter von entsprechend grofsem Leitungswiderstande. Steam or hot water can be used as a means for this purpose, which is passed through a line circulating downwards to the bottom of the borehole and up again, or heated bodies inserted into the borehole with the aid of wire ropes or chains or finally heated by the passage of an electric current Conductors with a correspondingly large line resistance.
Soll die Erwärmung der Bohrlochsohle und Bohrlochwände mittelst Dampfes geschehen, so stellt man neben der Bohrlochmündung einen Kessel auf, dessen Dampfraum man entsprechend mit der auf die Bohrlochsohle führenden Rohrleitung verbindet. Auf der Bohrlochsohle bringt man vorzugsweise ein Schlangenrohr an, welches das Ende des Saugrohres der Oelpumpe umgiebt und von welchem das Rückleitungsrohr für das Condensationswasser nach oben abgeht; das Wasser wird dann oben wieder als Speisewasser für den Kessel verwendet. If the bottom of the borehole and the walls of the borehole are to be heated by means of steam, then so a boiler is set up next to the mouth of the borehole and its steam chamber is set up accordingly connects to the pipeline leading to the bottom of the borehole. On the bottom of the borehole preferably attaches a serpentine pipe, which is the end of the suction pipe of the Oil pump surrounds and from which the return pipe for the condensation water going upwards; the water is then used again upstairs as feed water for the boiler.
Zur Erwärmung der Bohrlochsohle und Bohrlochwände durch heifses Wasser mufs das Wasser mittelst einer Pumpe in Circulation gesetzt werden.In order to heat the bottom of the borehole and the walls of the borehole with hot water, this is necessary Water can be set in circulation by means of a pump.
