Abstract
The utility model relates to an automatic height regulating degassing device for well logging, which mainly solves the shortage that the existing engine degasser can not automatically regulate height following the change of drilling levels. The utility model is characterized in that the degassing device also comprises an ultrasonic sensor, a driving circuit board for signal processing and a servo motor, and the servo motor, wherein the driving circuit board is used for processing liquid level signals from the ultrasonic sensor and driving the servo motor to work; the servo motor drives a drive gear (4) to rotate; the gear (4) is engaged with a drive rod (3) provided with gullets and fixed on a degasser (2). When the gear (4) rotates, the degasser (2) does up and down movement under the drive action of the drive rod (3). The utility model has the characteristics of automatic regulation of the degasser height and guarantee of conformance between the degasser and the liquid level, and ensures degassing efficiency and quality of logged gasometry information.
Description
Technical field:
The utility model relates to used a kind of operating apparatus in the oil field geologic Exploration Domain, especially relates to a kind of at the on-the-spot degasser that uses of well logging.
Background technology:
At present, be common engine degasser at the on-the-spot degasser that uses of well logging, this degasser is fixedly mounted on the drilling fluid canal, and the adjustment of its height need lean on its Machinery Ministry of manual adjustment to assign to finish.Use the existing problem of this degasser to be: in drilling process, because the liquid level of drilling fluid is subjected to its height of influence of various factors such as pumpage in continuous variation, but the position of degasser stirring rod can not change with the level change of drilling fluid, make the degree of depth that the degasser stirring rod immerses in the drilling fluid constantly change, cause the drilling well liquid measure instability of deviating from, thereby directly have influence on the constant of degasser efficient, the application of surveying data to gas has caused certain difficulty.In addition, in order to guarantee the highly stable of degasser as far as possible, operating personnel must be according to the variation of drilling fluid displacement, the in time artificial height of adjusting, and this has just increased operator's workload; Construction or in high density, high viscosity drilling fluid in the winter time when artificial adjustment is highly untimely, causes that the tracheae line freezes, stifled phenomenon easilier, has influence on normal drilling well job schedule greatly.
The utility model content:
Can not adjust the deficiency of height with the drilling well level change automatically in order to overcome existing engine degasser, the utility model provides a kind of well logging with adjusting the height degasser automatically, this kind well logging has height, assurance degasser and the conforming characteristics of liquid level that can adjust degasser automatically with adjusting the height degasser automatically, has guaranteed that the gas of degassing efficiency and admission is surveyed data quality.
The technical solution of the utility model is: this kind well logging is used and is adjusted the height degasser automatically, comprises degasser, ultrasonic sensor, signal processing and a driven by servomotor circuit board and a servomotor that is used to handle ultrasonic sensor liquid level signal and the work of driving servomotor.Ultrasonic sensor is followed the tracks of at any time and is detected the drilling well liquid level, forming the analog electrical signal input signal handles and the driven by servomotor circuit board, this signal is amplified by signal processing circuit, then to drive circuit, drive circuit is according to the variation drive motor of signal, this servomotor drives travelling gear by power transmission shaft and rotates, gear is meshed with the drive link that has teeth groove on being fixed in degasser, therefore when gear rotates, under the induced effect of drive link, degasser moves up and down accordingly.
The utlity model has following beneficial effect: adjust the height degasser automatically on the basis of common degasser owing to take the well logging of such scheme to use, ultrasonic sensor, signal processing and ingredients such as drive circuit and servomotor have been increased, device after make improving can be monitored the drilling well liquid level at any time and be adjusted the degree of depth that degasser immerses drilling fluid automatically, therefore guarantee degasser and liquid level uniformity, guaranteed the quality of the gas survey data of degassing efficiency and admission.
Description of drawings:
Accompanying drawing 1 is a composition schematic diagram of the present utility model;
Accompanying drawing 2 is schematic diagrames of mechanical part of the present utility model;
Accompanying drawing 3 is that the utility model signal is handled and driven by servomotor circuit board electrical schematic diagram.
1-drilling fluid canal among the figure, 2-degasser, 3-drive link, 4-travelling gear.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As Fig. 1 in conjunction with shown in Figure 2, this kind well logging is with adjusting the height degasser automatically, comprise a common degasser 2, its special character is: the signal that also comprises a ultrasonic sensor, liquid level signal that is used to handle come from ultrasonic sensor and drive servomotor work in this device is handled and driven by servomotor circuit board and a servomotor.Ultrasonic sensor is followed the tracks of at any time and is detected the drilling well liquid level, forming the analog electrical signal input signal handles and the driven by servomotor circuit board, this signal is amplified by signal processing circuit, and then to drive circuit, drive circuit drives servomotor according to the variation of signal.This servomotor at first drives travelling gear 4 by power transmission shaft and rotates, travelling gear 4 is meshed with the drive link that has teeth groove 3 on being fixed in degasser 2, therefore when travelling gear 4 rotates, under the induced effect of drive link 3, degasser 2 just can move up and down accordingly, when the detected liquid level signal back of ultrasonic sensor signal processing circuit and the difference of setting value be zero.
Fig. 3 handles and driven by servomotor circuit board electrical schematic diagram for signal, as can be seen from Figure: described signal processing and driven by servomotor circuit board are mainly by rectification module, Voltage stabilizing module, the rotating control module of CPU module and control servomotor constitutes, export to the CPU module as operating voltage after the DC voltage voltage stabilizing of Voltage stabilizing module with rectification module output, the data signal that attracts by ultrasonic sensor, and up and down limit switch signal as the input signal of CPU module, two digital signal output ends of CPU module are connected to the just commentaries on classics of rotating control module respectively, the counter-rotating control end, in this example, the CPU module can be selected 8051 single-chip microcomputers for use, the ZP8504-0.75 pattern piece that the rotating control module of control servomotor can select for use Shanghai GM electric equipment factory to produce.
Use the utility model effectively to prevent because the freezing of tracheae line, stifled phenomenon causes stops the brill accident, has effectively prevented the pollution of drilling fluid to chromatogram simultaneously, not only can avoid causing certain economic loss, and can guarantee the quality of log data.
