Hydraulic DTH rauj drilling yog ib qho kev hloov pauv loj ntawm cov pa rotary drilling thiab txoj kev drilling tshiab tom qab niaj hnub pob zeb diamond drilling thiab huab cua drilling. Nws ua kom zoo siv qhov tsis muaj zog ntawm cov pob zeb nyuaj, uas yog nkig, muaj zog shear tsawg thiab tsis tuaj yeem tiv taus qhov cuam tshuam. Nws yog ib qho cuab yeej zoo drilling los daws qhov teeb meem ntawm qhov tsis zoo ntawm qhov drilling efficiency thiab tsis zoo drilling zoo nyob rau hauv cov pob zeb nyuaj txheej thiab ib co complex pob zeb txheej.
Piv nrog cov pa rotary drilling, hydraulic DTH rauj drilling muaj qhov zoo hauv qab no:
(1) Ua kom tag nrho siv cov cuab yeej txhawb nqa ntawm qhov chaw, thiab tsis txhob hloov cov txheej txheem khiav haujlwm uas twb muaj lawm;
(2) Txij li thaum lub twj tso kua mis siab ntawm cov av nkos yog ib qho yooj yim kom ncav cuag tus nqi siab dua, hydraulic rauj adapts mus rau qhov loj dua qhov tob (nws tau mus txog 5118m);
Kev sib piv ntawm hydraulic rauj drilling thiab teb drilling
Kev sib piv ntawm hydraulic rauj drilling thiab teb drilling
(3) Kev ua haujlwm siab drilling hauv cov pob zeb nyuaj;
(4) Lub stratum tawg tsis yooj yim los thaiv cov tub ntxhais, thiab qhov thib ob txhaj tshuaj yog ntev;
(5) Ua kom ntev lub neej ntawm lub laum me ntsis;
(6) Rau ib qho twg, txo lub zog oblique ntawm lub qhov;
(7) Kev siv hluav taws xob tsawg thiab tsis muaj kuab paug ib puag ncig;
(8) Tsis ntshai dej hiav txwv, muaj peev xwm tiv thaiv phab ntsa;
(9) Yooj yim rau kev khiav lag luam thiab yooj yim los tswj.
