| Abstract: | The anti-circulation drilling of buried pore hammmer of through model with gas-operat-ed is a drilling technique using pressed air as power to break rock and flushing medium at-tached twic-wall pipes,establishing anticirculation continue getting core(sample)in pore.Based on the mechnism analysing of anti-circulation drilling,the authors have put forwordthat design bas is and principle of anti-circulation drill,on the basis of field producting testdata,the equipment necessary plan parameters of drilling rules and technological measure ofanti-circulation drilling of buried pore hammer of through.model with gas-operated have beendetermined. |
