Abstract
The utility model provides a three-component magnetometer in a well. The three-component magnetometer includes a magnetic-field sensor and a circuit board which drives the magnetic-field sensor to work and also includes an inclination-angle sensor which works under the drive of the circuit board. The magnetic-field sensor includes three component-detection magnetic-field magnetic sensing probes. Output ends of the magnetic-field sensor and the inclination-angle sensor are connected with input ends of a DSP through an A/D converter. An output end of the DSP is connected with a data output module. The three-component magnetometer in the well integrates the magnetic-field sensor and the inclination-angle sensor onto one circuit board so that the magnetometer is simple in mechanical structure and high in detection precision, which is not affected by external factors. At the same time, continuous measurement and automatic saving of data are realized.
Description
Technical field
The utility model belongs to the magnetic field measurement technology field, is specifically related to three-component magnetometer in a kind of well.
Technical background
In well, the three-component magnetometer is to measure the geological instrument of three of terrestrial magnetic field orthogonal vector along the borehole axis change in depth while holing for well, it is to be deep into the underground magnetic-field measurement of carrying out, the information material that ground magnetic field can't detect can be obtained, more complicated geology of deep part problem can be solved.The three-component magnetometer is mainly abnormal for verifying ground magnetic field at present, the magnetic ore body at the bottom of discovery probing Pang He hole, hole.So-called three-component refers to two geomagnetic field component X, Y and the vertical component Z in different depth point upper horizontal plane.The general vergence direction of gravity direction and boring that adopts is determined this measurement space coordinate system.
But current existing three-component magnetometer is that magneto sensor is arranged on movable framework, after inserting tube tilts, under Action of Gravity Field, keep the coordinate system of measuring system by mechanical system, cause measurement inaccurate.And the complex structure of three-component magnetometer, reliability are low, can only carry out down-hole anchor point survey.
The utility model content
In order to overcome the problems referred to above, the utility model provides three-component magnetometer in a kind of simple in structure, well that accuracy of detection is high.
The utility model solves the technical scheme that its safety problem adopts:
Three-component magnetometer in a kind of well, comprise magnetic field sensor and the circuit board that drives its work, described magnetic field sensor comprises the magnetic sensing probe in three component detection magnetic fields, also comprise the obliquity sensor by described circuit board driving work, described magnetic field sensor all is connected with the input end of DSP digital processing unit by A/D converter with the output terminal of obliquity sensor, and the output terminal of described DSP digital processing unit is connected with data outputting module.
Further, described magnetic field sensor all is connected with A/D converter by amplifilter with the output terminal of obliquity sensor.
Further, the output terminal of described DSP digital processing unit is connected with the input end of magnetic field sensor by D/A digital to analog converter, voltage regulator successively.
In well of the present utility model, the three-component magnetometer is integrated in magnetic field sensor and obliquity sensor on a circuit board, by coordinate transform, measured value is transformed into to terrestrial coordinate and fastens.Thereby reliability and the precision of instrument have greatly been improved.Also realized the continuous coverage of data, automatically preserved simultaneously.
What in this well, the three-component magnetometer adopted is digital measuring system, magnetic-field component X, the Y that heeling angle, trim angle data and the magnetic field sensor that it is detected obliquity sensor by the A/D converter of 12 detects, the data of Z are carried out Collect conversion, then carried out the coordinate conversion of signal processing and measurement result by the negative tribute of DSP digital processing unit, final by information concrete under the data outputting module output well.
The D/A digital to analog converter flows to driving voltage of magnetic field sensor by the loop numerical value of DSP digital processing unit feedback by voltage regulator, thus solve magnetic field sensor consistance, the depth of parallelism, turn to the indexs such as poor.Make magnetic field sensor in use, as clashed and its position is changed, voltage regulator, by the loop numerical value auto-compensation of DSP digital processing unit, is corrected it in certain scope.The driving voltage of voltage regulator output is 2.8～4.4V, thereby reduces the impact on magnetic field sensor sensitivity.
So in well of the present utility model, three-component magnetometer physical construction is simple, and its accuracy of detection is high, is not subject to the impact of extraneous factor; Also realized the continuous coverage of data, automatically preserved simultaneously.
The accompanying drawing explanation
Fig. 1 is this utility structure principle schematic.
