PLANT AND METHOD FOR ELECTRO-IMPULSE DRILLING AND LOGGING AND DEVICE FOR ELECTRO-IMPULSE DRILLING (VERSIONS)

摘要

FIELD: mining.;SUBSTANCE: plant for drilling and logging includes electro-impulse drilling device, at least one sonic-signal sensor and at least one electromagnetic signal sensor; the signals are generated by device for electro-impulse drilling. At that sonic-signal sensors are adapted to measure three vectors of displacement and one component of pressure. Besides the plant includes dipole electrodes silver-silver-chloride and spools with ferromagnetic core to measure electric and magnetic signals on surface or seabed, and coil antenna to measure electromagnetic signals in borehole. Method for drilling and logging and device for electro-impulse drilling are also proposed.;EFFECT: effective electro-impulse drilling with simultaneous logging of well.;13 cl, 3 dwg
