Hydraulic DTH rauj, hydraulic poob siab lossis hydraulic rauj), yog qhov cuam tshuam ntawm kev cuam tshuam hydraulic rotary drilling cuab yeej, nws siv nyob rau hauv tus txheej txheem ntawm drilling av nkos twj tso kua mis rinses lub zog mov ntawm ncaj qha tsav hydraulic rauj cuam tshuam rauj daim ntawv nce thiab nqis reciprocating tsab ntawv tsa suab hauv [ 1], thiab tsis tu ncua ua kom muaj qee zaus ntawm kev cuam tshuam ntawm cov cuab yeej drilling hauv qis, thiaj li ua tiav qhov cuam tshuam rau qhov drilling.
Hydraulic DTH drilling yog ib qho kev hloov kho zoo ntawm cov pa rotary drilling thiab txoj kev drilling tshiab tom qab niaj hnub pob zeb diamond drilling thiab huab cua drilling.Nws yog ib qho zoo drilling tshuab los daws qhov teeb meem ntawm qhov tsis zoo drilling efficiency thiab tsis zoo drilling zoo ntawm cov pob zeb nyuaj thiab qee cov pob zeb nyuaj strata los ntawm kev siv zoo ntawm cov tsis muaj zog ntawm cov pob zeb nyuaj nrog cov brittleness zoo thiab tsis tshua muaj zog shear.
Piv nrog cov pa rotary drilling, hydraulic DTH drilling muaj qhov zoo hauv qab no:
(1) Ua kom tag nrho siv cov khoom siv txhawb nqa rau ntawm qhov chaw thiab tsis txhob hloov cov txheej txheem khiav haujlwm uas twb muaj lawm;
(2) Vim tias lub twj tso kua mis siab ntawm cov av nkos yog ib qho yooj yim kom ncav cuag tus nqi siab dua, yog li hydraulic rauj ADAPTS mus rau qhov loj dua qhov tob;
(3) Cov pob zeb nyuaj tsim muaj siab drilling aging;
(4) Lub stratum tawg tsis yooj yim rau ntsaws, thiab cov duab ntev rov qab;
(5) Ua kom ntev lub neej me ntsis;
(6) Txo lub qhov oblique lub zog rau ib qho twg;
(7) Kev siv hluav taws xob tsawg dua thiab tsis muaj kuab paug ib puag ncig;
(8) Tsis ntshai ntawm aquifer, muaj peev xwm tiv thaiv phab ntsa;
(9) Yooj yim rau kev khiav lag luam thiab tswj.
