Description
Technical field
The utility model belongs to coal mine drilling technical field, relates in particular to a kind of instrument that the track of coal mine drilling is measured.
Background technology
China is the country of an oil starvation, weak breath, rich coal, and coal has important strategic position in national economy and social development.China can not change quite over a long time in future take coal as main energy resource structure, and coal will be the main body energy of China.In recent years, safe coal production situation is very severe, and particularly serious accident happens occasionally.National security agency pays much attention to gas drainage under suction work, essential technique using gas drainage under suction as control of coalmine gas, " first take out afterwards and adopt " one of 12 word policies of being listed in by national Coal Mine Safety Supervision Bureau gas control, China's gas drainage technique has had and has developed rapidly.But, China's gas drainage technique is still relatively backward with equipment, the firedamp taking-out discharging drilling although constructed in some region, but because existing conventional art cannot effectively be measured the actual path of common firedamp taking-out discharging drilling, cause actual drilling track and design drilling track to occur relatively large deviation, firedamp taking-out discharging drilling is constructed less than precalculated position, and gas drainage under suction blind area appears in coal seam, and gas burst accident still happens occasionally.Equally, in the middle of spy discharges water the construction works of holing, the most of collieries of China still cannot be measured space tracking and the position of boring, lack basis for estimation effective, science, cause Underwell permeable accident to happen occasionally.
In recent years, along with km directional drilling machine in Shanxi, the success in Shaanxi, Ningxia, Deng Di colliery, Inner Mongol applies, the transmission of coal mining drilling signal and measurement-while-drilling system have also progressively obtained application, the application of measurement-while-drilling system makes boring play the multiple actions such as gas pumping, geological structure location, the permeable structure detection of artesian water region, has played positive effect in mine safety production.Be proven, directional drilling technique is mainly adapted in the stable coal seam of geological conditions, in the bad ground of growing at the structure such as broken coal seam or the weak seam coal of complex geologic conditions, because drilling rod in directional drilling work progress does not rotate, the more common drilling process of deslagging situation is poor, very easily there is bit freezing, the accidents such as bury drills, even can there is drilling rod locking and cannot move back the situations such as brill, can not make measurement-while-drilling system Safe withdrawing, cause huge economic loss, one-tenth porosity and the pore-forming efficiency of directional drilling are significantly reduced, in this case, adopt common rig to carry out the boring of rotary drilling construction technology and have more advantage.But, while adopting common rotary drilling technological borehole, traditional construction technology cannot be measured accurately to drilling track, locus, and then cannot effectively eliminate gas drainage under suction blind area.
Utility model content
For this reason, technical problem to be solved in the utility model is to provide a kind of in the time that common rotary drilling technique is holed, and can carry out the drilling track measuring instrument of accurately measuring, the deficiency existing to overcome prior art to drilling track, locus.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of drilling track measuring instrument, it is characterized in that: be linked in sequence and form by inserting tube, data acquisition collector and cell tube, in described inserting tube, be provided with acceleration transducer, magnetoresistive transducer, AD conversion be set in described data acquisition collector and process memory module, in described cell tube, be provided with battery; Described acceleration transducer, described magnetoresistive transducer connect and described battery is all electrically connected described AD conversion and processes memory module.
In order to facilitate the derivation of data, be also provided with data-interface at the front end of inserting tube, described data-interface is electrically connected described AD conversion and processes memory module.
For in the time holing, inserting tube is played a protective role, on described inserting tube, also cover has inserting tube end cap.
For realize can synchronized time synthetic, in described data acquisition collector, be also provided with described AD conversion and process the timer that memory module is connected.
Adopt technique scheme, drilling track measuring instrument of the present utility model is arranged on without in magnetic drilling rod while use, the X-axis in the earth's magnetic field of each survey mark of Real-time Collection drilling track, Y-axis, the X-axis of Z axis component and acceleration of gravity, Y-axis, the component of Z axis, carry out data transaction and be stored in AD changing and processing on the storage chip of memory module at interval of the set time (>=10s), by the processing to data, can obtain on computers the azimuth of different measuring points in its corresponding measurement moment, inclination angle, these azimuths, inclination angle marks out and just can obtain drilling track.
Therefore, drilling track measuring instrument of the present utility model has been realized the measurement to drilling track, locus in the time that common rotary drilling technique is holed, and has simple in structurely, measures accurate advantage.
