Niaj hnub no, SDLQ cov kws kho mob muab qee cov lus qhia txog kev teeb tsa tus pas nrig rau kev ua haujlwm drilling rigs: #piling rig tshuab #
1. Thaum drilling nyob rau hauv ib qho nyuaj formations nrog rotary drilling rigs, siv tshuab - xauv laum rods thiab sib txhuam laum rods rau soft formations. Cov lus pom zoo no yuav tsum tau ua raws li nruj me ntsis.
2. Thaum drilling nyob rau hauv ib tug tshwj xeeb tsim rau ib tug ncua sij hawm, nws yog pom zoo kom muab ob txheej ntawm zoo tib yam xyaum rods rau alternating siv. Qhov no ua kom muaj kev tu thiab kho kom raws sijhawm, ua kom cov neeg siv kev tsim kho tau zoo.
3. Yog tias qhov torsional thiab compressive tsis kam ntawm lub laum pas nrig xaiv rau cov kev xav tau tshwj xeeb yog qis dua qhov tso tawm ntawm lub laum rig, kev ntsuas tsim nyog yuav tsum tau coj los tiv thaiv lub laum pas nrig los ntawm kev puas tsuaj.
4. Ua ntej siv laum pas nrig, thov nyeem phau ntawv qhia no kom tsis txhob ua haujlwm tsis raug.#piling rig tshuab#
SDLQ Editor's Warning:
1. Geological tej yam kev mob los yog txoj kab uas hla tshaj lub laum yeeb nkab lub peev xwm bearing yuav ua rau muaj kev huam yuaj. Yog hais tias qhov no tshwm sim, staged drilling yog pom zoo.
2. Qhov siab tshaj plaws linear tshaj tawm ntawm lub laum me ntsis cov hniav sab nrauv thaum lub sijhawm ua haujlwm yuav tsum tsis pub tshaj 0.8 m / s.
3. Txhua yam kev cuam tshuam tuaj yeem ua rau lub laum yeeb nkab puas.
4. Yog hais tias lub taub hau laum, laum yeeb nkab, thiab pawg lub qhov tsis concentric, lub laum yeeb nkab yuav raug rau cyclic dabtsi yog khoov lub sij hawm ntev.#piling rig tshuab#
