Description
Registriergerät zur Aufzeichnung von Meßgrößen in Abhängigkeit von der Teufe einer geologischen Bohrung Bei geologischen Bohrungen ist die Aufzeichnung der Änderungen insbesondere der Temperatur und des Druckes in Abhängigkeit von der Teufe der Bohrung wichtig, da aus dem Verlauf der Meßgrößen Schlüsse auf die Zusammensetzung und Ausdehnung der durchbohrten Schichten gezogen werden können. Es muß daher die Zuordnung zwischen der Registrierkurve und der Teufe der Meßsonde besonders genau eingehalten werden.Recording device for recording measured variables as a function of the depth of a geological borehole For geological boreholes, the record is the changes in particular the temperature and the pressure depending on the The depth of the borehole is important, as conclusions can be drawn about the composition from the course of the measured variables and expansion of the pierced layers can be drawn. It must therefore be the Allocation between the registration curve and the depth of the measuring probe is particularly precise be respected.
Hierzu ist es bekannt, über das Seil, an dem die Meßsonde hängt, bei dessen Einfahren ein Schlepprad zu betätigen und über dieses Schlepprad den Papiervorschub zu steuern. Es ist jedoch schwierig, eine ganz bestimmte Aufzeichnung der zugehörigen Schicht der Bohrung zuzuordnen, wenn der Registrierstreifen sehr lang ist.For this purpose, it is known about the rope on which the measuring probe is suspended its retraction to operate a drag wheel and the paper feed via this drag wheel to control. However, it is difficult to get a very specific record of the associated Assign the layer to the hole if the recording strip is very long.
Gemäß der Erfindung betätigt das Schlepprad mittels einer ein- oder mehrstufigen Untersetzung Kontakte, welche elektrische Widerstände im Meßstromkreis überbrücken. Sobald ein solcher Widerstand überbrückt wird, geht der Meßwert sprunghaft zurück, und an der Registrierkurve wird eine Teufemarke angebracht. Die Länge der Marke ist durch Wahl entsprechender, zu überbrückender Widerstände veränderbar. So können beispielsweise in Abständen von 5 oder 10 in kurze Strichmarken und in Abständen von 50 oder 100 m entsprechend längere Marken geschrieben werden. An Hand der Registrierkurve kann dann sehr genau die Lage einer Meßwertänderung abgelesen und der Teufe zugeordnet werden, in der sich die Meßsonde befindet.According to the invention, the tow wheel operated by means of a one or multi-stage reduction contacts, which have electrical resistances in the measuring circuit bridge. As soon as such a resistance is bridged, the measured value goes by leaps and bounds back, and a devil's mark is attached to the registration curve. The length of the Brand can be changed by choosing appropriate resistances to be bridged. For example, in intervals of 5 or 10 in short bar marks and in Correspondingly longer marks can be written at intervals of 50 or 100 m. Based the registration curve can then read off the position of a change in the measured value very precisely and the depth in which the measuring probe is located.
Die Erfindung ist an Hand der schematischen Zeichnung an einem Ausführungsbeispiel erläutert. Für das Zeichnungsbeispiel ist angenommen, daß ein Temperaturmeßwert mit einem Kompensationsschreiber aufgenommen wird. Das Widerstandsthermometer 1 ist mit Hilfe einer Dreileiterschaltung mit der Meßbrücke 2 verbunden. Das Kabel 3 des Thermometers, das die drei Leiter enthält, läuft an einem Schlepprad 4 vorbei, das an dem Kabel abrollt. Mit der bekannten Dreileiterschaltung lassen sich genaue Meßergebnisse erzielen, besonders dann, wenn zwischen dem Thermometer und der Meßbrücke verhältnismäßig lange Leitungen eingeschaltet sind. Die Meßbrücke wird an den Klemmen 5 und 6 mit Gleichstrom gespeist. Die Nulldiagonale der Brücke ist an einen Kompensationsverstärker 7 angeschlossen, dessen Ausgang auf einen Einstellmotor für die Verstellung des Brückenwiderstandes 8 wirkt. Der Widerstand 8 wird bei jeder Temperaturänderung selbständig so eingestellt, daß der Diagonalstrom der Brücke zu Null wird. Die Einstellung dieses Widerstandes ist in bekannter Weise ein Maß für die Größe des Meßwertes und wird über einen Trieb 9 auf das Schreiborgan 10 übertragen. Derartige Kompensationsschreiber sind an sich bekannt. Das Schlepprad 4 betätigt beispielsweise bei jeder Umdrehung mit Hilfe eines nicht dargestellten Schaltnockens den Kontakt 11 eines Klinkwerkes 12. Dieses Klinkwerk treibt das Schreibpapier 13 an. Das Schlepprad kann beispielsweise so bemessen sein, daß nach dem Vorbeilaufen von jeweils 0,5 m Kabel ein Kontaktschluß erfolgt. Über das Klinkwerk 12 wird jeweils das Papier z. B. um 1/z oder 1 mm weiterbewegt. Vom Schlepprad 4 wird mit Hilfe einer Untersetzung ein Zahnrad 14 angetrieben, das an einer Stelle seines Umfangs einen Schaltnocken 15 aufweist. Dieser Nocken arbeitet mit einem Kontakt 16 zusammen, der einen Teil des Widerstandes 17 in der Meßbrücke kurzschließt. Über eine weitere Untersetzung wird das Zahnrad 20 angetrieben, das mit Hilfe seines Nockens 19 den Kontakt 21 schließt. Dieser Kontakt schließt den ganzen Widerstand 17 kurz.The invention is based on the schematic drawing of an embodiment explained. For the drawing example it is assumed that a temperature reading is recorded with a compensation recorder. The resistance thermometer 1 is connected to the measuring bridge 2 by means of a three-wire circuit. The cable 3 of the thermometer, which contains the three conductors, passes a tow wheel 4, that unrolls on the cable. With the well-known three-wire circuit, precise Achieve measurement results, especially when between the thermometer and the measuring bridge relatively long lines are switched on. The measuring bridge is attached to the terminals 5 and 6 fed with direct current. The zero diagonal of the bridge is connected to a compensation amplifier 7 connected, the output of which is connected to an adjusting motor for adjusting the Bridge resistance 8 acts. The resistor 8 increases with every change in temperature automatically adjusted so that the diagonal current of the bridge becomes zero. The setting this resistance is, in a known manner, a measure of the size of the measured value and is transmitted to the writing member 10 via a drive 9. Such compensation recorders are known per se. The tow wheel 4 actuates, for example, with every revolution with the help of a switching cam, not shown, the contact 11 of a ratchet mechanism 12. This latch mechanism drives the writing paper 13. The tow wheel can for example be dimensioned in such a way that a contact closure occurs after each 0.5 m of cable has passed he follows. The paper z. B. moved by 1 / z or 1 mm. From the drag wheel 4, a gear 14 is driven with the help of a reduction, which has a switching cam 15 at one point on its circumference. This cam works with a contact 16 together, which is part of the resistor 17 in the measuring bridge shorts. The gear 20 is driven via a further reduction the contact 21 closes with the aid of its cam 19. This contact closes the whole resistance 17 short.
Werden beispielsweise beide 'Untersetzungen im Verhältnis 1:10 ausgeführt, so werden nach dem Vorbeilaufen von jeweils 5 m des Kabels 3 der Kontakt 16 und nach dem Vorbeilaufen von jeweils 50 m der Kontakt 21 geschlossen. Sobald ein Teil des Widerstandes 17 durch den Kontakt 16 überbrückt wird, ist die Brücke 2 verstimmt, und der Meßwert sinkt sprunghaft ab. Ein solcher Sprung ist in der Registrierkurve als Strichmarke 22 erkennbar. Wird der ganze Widerstand 17 kurzgeschlossen, so sinkt der Meßwert noch weiter ab, und es wird eine längere Strichmarke 23 geschrieben. Bei dem erläuterten Beispiel folgt jeweils auf zehn Marken 22 eine längere Marke 23. Der Abstand der Marken 23 entspricht jeweils 50 m Teufe, während der Teufeabstand der Marken 22 5 m beträgt.For example, if both 'reductions are carried out in a ratio of 1:10, so after each 5 m of the cable 3, the contact 16 and after the passage of 50 m in each case, contact 21 is closed. Once a part of the resistor 17 is bridged by the contact 16, the bridge 2 is out of tune, and the measured value drops sharply. Such a jump is in the registration curve recognizable as a line mark 22. If the entire resistor 17 is short-circuited, it drops the measured value continues to decrease, and a longer line mark 23 is written. In the example explained, ten marks 22 are followed by a longer one brand 23. The distance between the marks 23 corresponds in each case to a depth of 50 m, while the devil distance of marks 22 is 5 m.
