DHD / SD / QL siab cua siab impactors yog siv ua ke nrog Eccentric Casing System drilling khoom. Lawv feem ntau ua haujlwm hauv cov haujlwm engineering xws li lub hauv paus pawg, tsheb ciav hlau, txoj kev loj, txuas hniav, vaj tse, thiab kev txhawb nqa txoj kab nqes.
Drilling khoom rau Eccentric Casing System tseem hu ua cov khoom siv pov tseg pov tseg. Cov qauv yog hloov kho kom haum raws li qhov xav tau ntawm cov neeg siv khoom. Qhov tob qhov tob yog li ntawm 0 mus rau 200m, thiab txoj kab uas hla ntawm qhov drilling yog li ntawm 76 txog 1096mm.
Pilot Bit thiab Blocks ua cov cuab yeej drilling lub rooj sib txoos.
Cov no yog cov kauj ruam Eccentric Casing System yuav siv los ua haujlwm:
1. Hloov ntawm cov cuab yeej drilling Cov yeeb nkab khau thiab cov yeeb nkab ua raws li tau tsav los ua raws li cov reaming thaiv txav tawm ntawm lub chute ntawm qhov nruab nrab me ntsis thiab qhib rau qhov chaw nyob ib puag ncig los tsim kom muaj ntau yam reaming.
2. Lub laum me ntsis tuaj yeem tsa tau thaum nws sib cuag nrog lub pob zeb iab. Lub laum me ntsis tuaj yeem raug tsa los ntawm lub qhov hauv pem teb tom qab lub reaming block tau sib sau ua ke.
3. Ua raws li kev tsim kho tom ntej.
