At present, significantly improve with the underground survey technology in China's drilling well overall technology level and develop rapidly.But a lot of running parameters of drill bit all are to use ground instrument to measure, because down-hole situation complexity, through hundreds of and thousands of meters transmission, data that measure and down-hole truth have bigger error to parameter in the well that is the space curve that crawls.We also can't directly obtain the real work parameter of drill bit.The parameter of measuring the drilling engineering down-hole seems very difficult.Domestic underground vibrating measuring technique also has sizable gap with comparing abroad, does not have practical underground vibrating measuring instrument.Can not control drilling parameter effectively, will cause energy not to be applied to the shaft bottom by drill bit effectively and break rock, and reduce rate of penetration, and may damage drill bit and drilling tool, bring out down-hole accident.
The utility model content
The purpose of this utility model is: a kind of underground vibrating measuring instrument is provided, employing fixedly 3-axis acceleration sensor and microprocessor etc. on joint body, can gather drill bit and drill string forced vibration signal, by analyzing the relation between grasp bit force and drilling parameter, drilling quality, the bit speed, adjust drilling parameter, reach the purpose that improves bit speed, creeps into safely.
The technical solution adopted in the utility model is: the underground vibrating measuring instrument, mainly to form by instrument tube and joint body, and joint body is the cylinder bodily form, and centre bore is arranged, there is connecting thread at two ends, can be connected between drill collar and the drill bit.It is characterized in that: the axial restraint groove is arranged on the joint body outer wall, be fixed with the instrument tube in the holddown groove.Adopt screw that cover plate is arranged on holddown groove, cover plate can seal and make the instrument in instrument tube and the instrument tube injury-free.Be fixed with electronic measurement system in the instrument tube, electronic measurement system comprises 3-axis acceleration sensor, signal adjusting module, multicircuit switch, mould/number conversion module, clock control module, microprocessor, testing data memory, data-interface, power supply and power transfer module.3-axis acceleration sensor connects signal adjusting module, multicircuit switch and mould/number conversion module successively by holding wire, and mould/number conversion module connects microprocessor; Microprocessor is connected with testing data memory, clock control module and data-interface.At the instrument tube power supply is arranged, power supply connects 3-axis acceleration sensor by power line.Power supply also is connected with power transfer module by power line.Power transfer module connects signal adjusting module, multicircuit switch, mould/number conversion module, clock control module, testing data memory, microprocessor and data-interface, and power supply provides electric energy for electronic measurement system.
The model of described 3-axis acceleration sensor is 13510 types, and there is production marketing in market.
Described power supply is 27.3 volts of direct current lithium battery groups.
The model of described microprocessor is the STC12C2052 type.
The operating principle of underground vibrating measuring instrument: the underground vibrating measuring instrument adopts memory-type to measure, and handles and stores behind vibration signal in underground survey.In order to measure the vibration of drilling tool in the down-hole all directions, 3-axis acceleration sensor is selected by system.Three-dimensional vibrating signal when 3-axis acceleration sensor is measured drilling well, carry out preliminary treatment by holding wire entering signal adjusting module, entering multicircuit switch again selects certain road or several signals to enter A/D converter respectively analog signal conversion is become data signal, data signal after the conversion enters the Digital Signal Processing that microprocessor is correlated with, and the result who handles will deposit data storage module in.Finish the drill vibration signal measurement, after vibration measuring set reclaimed, microprocessor linked to each other with host computer by data interface circuit, and the data of storage are sent on the host computer, clock control module is controlled the startup of microprocessor, and power supply and modular converter thereof provide electric energy for other module.
The beneficial effects of the utility model: the utility model underground vibrating measuring instrument, be installed in G.I.H between drill bit and the drill collar, in the wellbore construction process, can carry out the measurement and the storage of drill bit, vibration signals of drilling rod, the vibrational state of findding out downhole tool for the drilling well scientific and technical personnel provides reliable foundation; Utilize the signal of grasping can predict the trend of work of Bottom Hole Assembly (BHA), significant to the harm of avoiding the shaft bottom vibration to bring; Also instruct the drilling parameter choose reasonable, reduce instrument premature wear or impact failures such as drill bit, drill string and MWD, realized drilling well safely and fast, satisfy the needs of wellbore construction.
