Cia kuv qhia koj txog cov teeb meem feem ntau ntsib hauv Kev Tsim Kho Cov Lus Qhia Drilling Rigs
Jul 06, 2022| Directional drilling rigs feem ntau nres drilling thaum tsim kho. Nws yog feem ntau siv hauv kev tsim kho. Koj puas paub cov teeb meem feem ntau ntsib hauv kev tsim kho ntawm kev taw qhia drilling? Cov editor nram qab no yuav qhia qee cov ntaub ntawv rau koj, vam tias yuav pab tau koj.
1. Qhov lub cev deflection: nyob rau hauv cov ntaub ntawv ntawm lub deflection ntawm lub qhov lub cev tshwm sim los ntawm kev siv lub directional drilling tshuab, nws yog feem ntau ua tau kom dai lub laum lub khob ntawm deflection thiab nres rov qab lub qhov tu kom lub drilling dlej; Thaum lub deflection loj heev, nws yog ib qho tsim nyog yuav tsum tau rov qab cov av cohesive rau lub deflection nyob rau hauv lub sij hawm, thiab ces nres lub drilling lag luam tom qab lub tsub zuj zuj yog ntom.
2. Reaming thiab shrinkage: nyob rau hauv cov ntaub ntawv ntawm reaming thiab shrinkage, kev ntsuas yuav tsum tau coj los tiv thaiv lub qhov vau thiab lub viav vias ntau dhau ntawm lub laum lub khob. Cov qub yuav tsum tau ua tib zoo saib xyuas kom tsis txhob vuam thiab kho lub pob zeb drilling hauv lub sijhawm, thaum lub sijhawm tom kawg yuav tsum tau siv slurry nrog cov dej poob qis los tiv thaiv phab ntsa. Qhov tshwm sim ntawm shrinkage yuav tsum tau xyaum lub khob hliav qab kom tsis txhob rov qab qhov scanning nce thiab nqis kom nthuav nws aperture.
3. Paste drilling thiab faus drilling: muab tshuaj txhuam thiab faus drilling feem ntau nthuav tawm hauv thim rov qab drilling thiab percussive drilling hauv qhov zoo (xws li submersible drilling rigs). Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum tsis txhob kuaj xyuas thiab txheeb xyuas qhov sib xws ntawm cov av nkos, qhov nkag thiab qhov hluav taws xob ntawm qhov drilling slag, qhov loj ntawm cov yeeb nkab hauv txoj kab uas hla thiab cov cuab yeej tshem tawm slag; Yog tias qhov drilling tau daig hnyav heev, nws yog qhov yuav tsum tau nres qhov drilling tam sim ntawd, muab tso rau pem hauv ntej lub khob hliav qab thiab tshem tawm cov slag drilling.
4. Kev sib txuas: nws feem ntau tshwm sim thaum siv cov kev taw qhia drilling rig kom tsis txhob cuam tshuam kev ua haujlwm drilling. Kev quab yuam lifting tsis tuaj yeem nres tom qab lub laum yog daig, thiab nws tsuas tuaj yeem nqa tau maj mam.
5. Drilling thiab ntog khoom: thaum drilling thiab ntog khoom, nws yog tsim nyog kom tsis txhob nuv ntses nrog rab rawg, hooks, hlua tes tsho thiab lwm yam. Yog tias cov khoom poob tau raug faus los ntawm cov av nkos, nws yog ib qho tsim nyog yuav tsum tsis txhob ntxuav cov av nkos thiab xuab zeb ua ntej nres nuv ntses.
Nyob rau hauv txhua qhov xwm txheej, cov neeg ua haujlwm kev taw qhia drilling rig tsis tuaj yeem nkag mus rau hauv lub qhov borehole yam tsis muaj casing lossis lwm yam khoom siv tiv thaiv los daws qhov teeb meem. Thaum drilling qhov qis qis los yog lwm yam khoom siv tiv thaiv, nws yog ib qho tsim nyog yuav tsum tau xyuas kom tsis muaj cov pa phem hauv lub qhov thiab npaj cov khoom siv rau kev tiv thaiv roj, kev tiv thaiv kev poob dej thiab kev tiv thaiv kev sib tsoo.
