Unattended wireless inclinometry while drilling system

Abstract

The invention provides an unattended wireless inclinometry while drilling system. A triaxial acceleration sensor collects an inclination angle value of a borehole; a gyroscope sensor obtains the inclination angle value under the condition that a probe rod does not rotate; a triaxial magnetic field sensor collects the azimuth angle of the borehole; and a microprocessor transmits the inclination angle value and azimuth angle value to a synchronous machine through a communication module, the inclination measurement of a drilling track can be completed during the drilling process, so that the realintegrated inclination measurement while drilling can be realized, the time for increasing the probe rod can be automatically judged, unattended operation can be realized, workload can be reduced, power consumption can be reduced meanwhile, the unattended wireless inclinometry while drilling system can work continuously for a long time after being charged once, inconvenience caused by frequent charging can be avoided, and a plurality of functions are added to the synchronous machine meanwhile, operations originally required to be completed by a surface computer can be transplanted to the synchronous machine, so that the problem that all work can be completed underground can be solved. The probe rod is divided into a sensor protection tube and a battery protection tube, and can be directlyreplaced when one of the sensor protection tube and the battery protection tube has problems.

Description

technical field [0001] The invention relates to the field of drilling inclinometers, in particular to an unattended wireless inclinometer while drilling system. Background technique [0002] The inclinometer while drilling is currently widely used in the field of drilling inclinometers in petroleum geological exploration, coal mines, municipal administration, hydrology and other industries. It consists of data processing instruments and drilling rods (pipes). By type, it can be divided into non-while-drilling inclinometer and while-drilling inclinometer. [0003] Since the non-while-drilling inclinometer is used, the probe rod is sent into the drilled hole, and it needs to be connected with a cable to measure, which increases the work steps, takes a long time, and is costly, so now the inclinometer while drilling is mostly used instrument. The existing inclinometer while drilling generally uses the probe rod to send the probe tube into the borehole for measurement, and it...

Problems solved by technology

[0003] Since the non-while-drilling inclinometer is used, the probe rod is sent into the drilled hole, and it needs to be connected with a cable to measure, which increases the work steps, takes a long time, and is costly, so now the inclinometer while drilling is mostly used instrument

The existing inclinometer while drilling generally uses the probe rod to send the probe tube into the borehole for measurement, and it still needs to be drilled to measure, which is not a real inclinometer while drilling, so the design is unreasonable and inconvenient to use; At the same time, the power consumption is large, the working time of the battery is short, and frequent charging is required; and one synchronous machine can only control one probe rod, and multiple sets of synchronous machines are required to drill multiple holes at the same time, and the cost is high

[0004] The probe rod also collects data during the drilling process. Due to the rotation of the probe rod, the collected data is not accurate enough. In order to obtain accurate data during the static time, the time point can only be recorded during the time when the probe rod is suspended for drilling. The process is cumbersome.
