Abstract

This is an arrangement for the continuous degassing, by producing an underpressure, of liquids with or without solid particles, in particular drilling mud, shut off from the surrounding air. Arrangement, intended for analytic purposes, includes the liq. being fed into the inner (2) of two cylinders, where it is ground, whirled around, centrifuged (10) and thrown over the top of this cylinder (2) down into the outer cylinder (1). Outer cylinder forms a low-pressure chamber and is open at the bottom, which is in a tank (14). This cylinder has, at the top, a gas outlet pipe (4) connected to a pump (15) that produces an underpressure in the cylinder (1). This degassing system is downwardly shut off from ambient influence, and solid particles can fall into the tank (14). USE/ADVANTAGE - Drawbacks both of discontinuous and of other continuous systems for use with such analyses are overcome. Test measurements, together with analysis of the gas, enable quantitative and qualitative information on the gas-bearing rock formation contg. the borehole to be obtd.

Description

Beim Abteufen von Bohrungen wird durch das Zerstören des durchteuf­ ten Gebirges durch den Bohrmeißel Gestein, Fluide und Gase freige­ setzt, die an der Bohrlochsohle in die umlaufende Spülung gelangen. Darüber hinaus können Fluide und Gase aus dem Gebirge im Bereich des unverrohrten Bohrlochs in die Spülung migrieren.When drilling holes, it is destroyed by destroying the rock, fluids and gases through the drill bit sets that get into the circumferential mud at the bottom of the borehole. In addition, fluids and gases from the mountains in the area of Migrate uncased borehole into the mud.

Insbesondere an Erdöl- und Erdgasbohrungen ist es für die Geowissen­ schaft von Wichtigkeit, daß aus der von der Bohrlochsohle aufsteigen­ den Bohrspülung, einschließlich des zerbohrten Gesteins, das enthal­ tene Gas ohne Kontamination mit der Atmosphäre, kontinuierlich aus der Bohrspülung gewonnen werden kann.It is particularly important for geosciences at oil and gas wells important that rise from the bottom of the borehole the drilling fluid, including the drilled rock, that contains gas continuously without contamination with the atmosphere the drilling fluid can be obtained.

Es ist bekannt, daß Bohrspülung und Bohrklein für analytische Zwecke entgast wird (deutsche Patentschrift Nr. 12 41 155). Die dabei ver­ wendeten Systeme arbeiten entweder diskontinuierlich ohne Beeinflus­ sung von Umgebungsluft oder kontinuierlich wobei eine Umgebungsluft­ beeinflussung nicht ausgeschlossen werden kann.It is known that drilling fluid and cuttings are used for analytical purposes is degassed (German Patent No. 12 41 155). The ver The systems used either work discontinuously without interference solution of ambient air or continuously being an ambient air influence cannot be excluded.

Weiterhin ist bei Durchlaufsystemen keine ausreichende Sicherheit für störungsfreien Betrieb, hinsichtlich Verunreinigungen und Ver­ stopfungen bei hohem Feststoffanteil und deren Entsorgung, gegeben.Furthermore, there is insufficient security in continuous systems for trouble-free operation, with regard to impurities and ver blockages with high solids content and their disposal.

Die Erfindung betrifft eine kontinuierlich arbeitende Entgaserein­ richtung im Durchlaufprinzip zum Entgasen und zur Entnahme von in Flüssigkeiten mit Feststoffanteilen enthaltenen Gasen, insbesondere zum Entgasen von Bohrspülung einschließlich Feststoffanteilen ohne eine Kontamination der gewonnenen Gasprobe mit Umgebungsluft, wobei die gewonnene Gasprobe anschließend analysiert wird.The invention relates to a continuously operating degasser Direction in the flow principle for degassing and for the removal of in Liquids containing gases containing solids, in particular for degassing drilling fluid including solid matter without contamination of the gas sample obtained with ambient air, where the gas sample obtained is then analyzed.

Die in Anspruch 1 angegebene Erfindung löst das Problem einer konti­ nuierlichen Entgasung im Durchlaufprinzip, bei gleichzeitiger Fest­ stoffausscheidung in die an Bohranlagen vorgesehenen Entsorgungsbe­ hälter und eine Trennung des Gassammelraums gegenüber der Umgebungs­ luft, auch bei Unterbrechung der Flüssigkeitzuführung. The invention specified in claim 1 solves the problem of a continuous Nuclear degassing based on the continuous principle, with simultaneous fixed Substance separation in the disposal facilities provided on drilling rigs container and a separation of the gas collection space from the environment air, even if the liquid supply is interrupted.  

Eine vorteilhafte Ausstattung der Erfindung ist in Anspruch 2 angege­ ben. Durch entsprechendes Messen der Zulaufmenge (11), des Unter­ drucks (12), der abgesaugten Gasmenge (13) und der Analyse des gewon­ nenen Gases, ist die Möglichkeit gegeben, eine qualitative und quan­ titative Aussage über die gasführenden Formationen des durchteuften Gebirges zu treffen.An advantageous equipment of the invention is specified in claim 2 ben. By appropriately measuring the supply amount ( 11 ), the negative pressure ( 12 ), the amount of gas extracted ( 13 ) and the analysis of the gas obtained, it is possible to make a qualitative and quantitative statement about the gas-bearing formations of the intersected mountains .

Nachfolgend wird die Erfindung an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is described below with reference to one in the drawing illustrated embodiment explained in more detail.

Die Erfindung beinhaltet eine kontinuierliche Flüssigkeitszuführung, einschließlich Feststoffanteilen über eine Pumpe (16), zentrisch in den Entgaserinnenzylinder (2) , einschließlich einer Mengenmessung (11), einer Zerkleinerung, Verwirbelung und Zentrifugierung (10) der Flüssigkeit, und deren Feststoffanteile. Der kontinuierliche Aus­ tritt der entgasten Flüssigkeit mit Feststoffanteilen geschieht durch den unten offenen Entgaseraußenzylinder (1). Gegen eine Umge­ bungsluftbeeinflussung, der im oberen Bereich des Entgaseraußenzylin­ der (1) sich sammelnden Gasprobe, sorgt das Flüssigkeitsnivau der entgasten Flüssigkeit im Behälter (14), der den Gassammelraum nach unten abschließt.The invention includes a continuous liquid supply, including solid components via a pump ( 16 ), centrally in the degassing inner cylinder ( 2 ), including a quantity measurement ( 11 ), size reduction, swirling and centrifuging ( 10 ) of the liquid, and their solid components. The continuous degassing of the degassed liquid with solids occurs through the open degasser outer cylinder ( 1 ). Against an ambient air influence, the gas sample collecting in the upper area of the degassing outer cylinder in ( 1 ), ensures the liquid level of the degassed liquid in the container ( 14 ), which closes the gas collecting space at the bottom.

Der Behälter (14) gewährleistet, zusammen mit der Höhenpositionie­ rung des Auslaufs (9) und der Eintauchtiefe (17) des Entgaseraußenzy­ linders (1), daß auch bei einer Unterbrechung der Flüssigkeitszufüh­ rung der Gassammelraum nach unten gegen Umgebungsluftbeeinflussung abgeschlossen bleibt. Durch den unten, für Feststoffanteile offenen Außenzylinder (1) ist ein sicheres Abscheiden der Feststoffanteile in den dafür an Bohranlagen vorgesehenen Entsorgungsbehälter (14) sichergestellt.The container ( 14 ) ensures, together with the Höhenpositionie tion of the outlet ( 9 ) and the immersion depth ( 17 ) of the degasser outer cylinder ( 1 ), that the gas collection chamber remains closed against the influence of ambient air even when the liquid supply is interrupted. The outer cylinder ( 1 ), which is open at the bottom for solids, ensures that the solids are separated reliably into the disposal container ( 14 ) provided for this purpose on drilling rigs.
