Cov teeb meem thiab kev daws teeb meem hauv Kab rov tav Directional Drilling Tshuab kev tsim kho
Dec 23, 2022| 1. Lub cev deflection: Nyob rau hauv cov ntaub ntawv ntawm lub cev deflection tshwm sim los ntawm kev siv Kab rov tav Directional Drilling Tshuab, feem ntau nws yog ua tau kom dai lub laum lub khob ntawm lub deflection taw tes thiab ces scan lub qhov rov ua kom lub qhov ncaj; Thaum lub deflection loj heev Nws yog ib qho tsim nyog yuav tau rov qab ua cov av cohesive rau lub deflection nyob rau hauv lub sij hawm, thiab xyaum tom qab lub deposit yog compacted.
2. Qhov kev nthuav dav thiab qhov shrinkage: yuav tsum tau ntsuas los tiv thaiv lub qhov tawg thiab ntau dhau kev laum lub khob hliav qab nyob rau hauv cov ntaub ntawv ntawm lub qhov expansion los yog shrinkage. Cov qub yuav tsum tau them sai sai rau lub sijhawm vuam thiab kho lub laum lub khob hliav qab, thiab tom kawg yuav tsum tau txais cov av nkos khaws cov phab ntsa nrog cov dej me me. Lub shrinkage kab noj hniav uas tau tshwm sim yuav tsum tau soj ntsuam nce thiab nqis rov qab nrog lub laum lub khob kom nthuav nws lub qhov taub.
3. Paste drilling thiab faus drilling: Muab tshuaj txhuam thiab faus drilling feem ntau tshwm nyob rau hauv rotary drilling thiab percussion drilling nyob rau hauv zoo ncig (xws li submersible drilling rigs). Nyob rau lub sijhawm no, nws yog ib qho tsim nyog los xyuas thiab xam qhov sib xws ntawm cov av nkos, kev xa tawm thiab xa tawm ntawm cov slag slag, qhov loj ntawm lub puab kab ntawm lub laum yeeb nkab, thiab cov khoom siv slag tawm; Yog hais tias lub laum yog heev daig, nws yog ib qhov tsim nyog yuav tsum tsis txhob drilling tam sim ntawd tshem tawm lub laum lub khob hliav qab thiab tshem tawm cov drilling slag.
4. Drilling sticking: Nws feem ntau tshwm sim hauv kev ua haujlwm ntawm percussion drilling siv Kab rov tav Directional Drilling Tshuab. Tom qab lub laum yog daig, lub lag luam uas tsis tuaj yeem nqa los ntawm kev quab yuam tuaj yeem nqa tau yooj yim.
5. Drilling khoom: Thaum tso cov khoom, nws raug nquahu kom siv cov cuab yeej xws li hooks lossis hlua kom ceev lawv. Yog tias cov khoom poob tau raug faus los ntawm cov xuab zeb, nws yuav tsum tau tshem cov xuab zeb thiab siv cov cuab yeej los cawm. .
Nyob rau hauv tsis muaj qhov xwm txheej yuav tsum tus neeg teb xov tooj kab rov tav Directional Drilling Tshuab nkag mus rau hauv lub qhov borehole yam tsis muaj lub casing lossis lwm yam khoom siv tiv thaiv los daws teeb meem. Thaum drilling qhov nyob rau hauv qis casing los yog lwm qhov chaw tiv thaiv, nws yog ib qhov tsim nyog los xyuas kom meej tias tsis muaj cov pa phem nyob rau hauv lub qhov thiab npaj anti-virus, anti-drowning thiab anti-collapse khoom ua ntej yuav ua.
