A kind of integral coal mine electromagnetic wave wireless drilling measurement mechanism of the utility model, described power supply pipe nipple, measurement emission pipe nipple, lead-in wire top assembly are positioned at non-magnetic drilling tool, pass through the airtight connection of screw thread between the adjacent component.
The described measurement emission of the utility model pipe nipple passes through measuring element collection and coding down-hole formation metrical information wherein, and passes to the ballistic device of measuring in the emission pipe nipple; One utmost point of the driving source of ballistic device links to each other with non-magnetic drilling tool through screw; Another utmost point links to each other with lead terminal fixed tray in the upper drilling string via lead-in wire top assembly through armored cable; The driving source of down-hole emission is obstruct with the insulating short section; In measuring emission pipe nipple, armored cable, upper drilling string, stratum, non-magnetic drilling tool, form current loop; Down-hole information is transmitted with form of electromagnetic wave in magnetic field around current loop produces, and the receiving system in the signal receiving unit receives electromagnetic wave signal through the potential difference of measuring between earthing electrode and the upper drilling string, and measures the information of gained by the receiving system processing with showing the shaft bottom.
The device of the utility model in use, the pipe string combination form in the borehole wall up is followed successively by drill bit, lower drilling string, non-magnetic drilling tool, insulating short section and upper drilling string the end of from.
Metal parts all uses fine copper or brass or beryllium copper to make in the device power supply pipe nipple of the utility model, measurement emission pipe nipple and the lead-in wire top assembly.
The utlity model has following beneficial effect:
1, the apparatus cost of the utility model is lower; Easy to use; Use this device can keep in present most of coal mine still, avoided transforming or purchasing the required high expense of new equipment again, practiced thrift construction and cost of production at drilling equipments such as common drilling rod that uses and common rigs.
2, the metalwork in the power supply pipe nipple in the utility model device, measurement emission pipe nipple and the lead-in wire top assembly all adopts brass or fine copper or beryllium copper to make; Meet the requirement of Safety of Coal Mine Production, adopt the copper material processing component can guarantee that its measuring process does not receive the interference of magnetic material simultaneously.And these parts adopt aluminum not have the magnetic material mostly in petroleum industry electromagnetic wave wireless drilling system, and aluminum material use in coal mine has the hidden danger of blasting, so do not meet the requirement of Safety of Coal Mine Production.
3, in the device of the utility model measuring element and ballistic device are incorporated in the measurement emission pipe nipple, have shortened instrument needed space length in well, reduced the use of material, reduced manufacturing cost.
