1. Cov khoom muaj feem cuam tshuam
Ib qho yog qhov cuam tshuam ntawm drilling siab ntawm drilling ceev. Laum siab yog hais txog lub siab siv los ntawm lub laum me ntsis mus rau nruab nrab tom qab rho tawm ntau yam kev tawm tsam los ntawm cov khoom noj pub zog los ntawm lub tshuab drilling. Kev xyaum qhia tau hais tias nyob rau hauv tej yam kev mob drilling, lub laum siab yog linearly ntsig txog qhov drilling ceev tshaj ib tug loj ntau yam. Thaum tus nqi laum siab yog ua ntej point 1, qhov drilling ceev yog qeeb heev vim qhov tsis tshua muaj siab. Tom qab taw tes 2, lub laum siab siab dhau lawm, thiab lub laum me ntsis tsis ua kom tiav qhov nruab nrab, ua rau muaj zog slag tawm, tsis zoo cua txias ntawm lub laum me ntsis, nce hnav, thiab cov nyhuv drilling tsis zoo.
Qhov thib ob yog qhov cuam tshuam ntawm kev sib hloov ceev ntawm drilling ceev. Kev sib hloov ceev tso zis los ntawm qhov drilling rig sawv cev rau qhov ceev ntawm qhov laum me ntsis txiav qhov nruab nrab hauv qab ntawm lub qhov. Nyob rau hauv txoj kev xav, qhov drilling ceev nce nrog qhov nce ntawm kev sib hloov ceev, tab sis nyob rau hauv kev xyaum, ob tsis yog linearly ntsig txog. Qhov drilling ceev muaj qhov tseem ceeb, thiab dhau ntawm tus nqi no, nws yuav tsis nce vim qhov nce ntawm kev sib hloov ceev, tab sis yuav txo qis. Qhov laj thawj tseem ceeb yog tias lub laum me ntsis muaj lub sijhawm luv luv ntawm qhov nruab nrab ntawm qhov nruab nrab, uas cuam tshuam rau qhov tob ntawm kev nkag mus. Nyob rau tib lub sijhawm, kev kub ceev ntawm kev sib hloov ua rau muaj qhov kub thiab txias nyob rau hauv qab ntawm lub qhov, thiab qhov hnav ntawm lub laum me ntsis intensifies. Kev sib raug zoo ntawm kev sib tsoo ceev thiab kev sib hloov ceev hauv kev tshaj tawm nrog cov khoom abrasive tsawg yog qhov pib linear. Kev sib raug zoo ntawm nruab nrab drilling ceev thiab kev sib hloov ceev maj mam qeeb nrog nce kev sib hloov ceev, thiab qhov loj ntawm qhov txo qis hauv drilling ceev sib txawv nrog cov pob zeb, drilling siab, thiab cov cuab yeej drilling.
2. Lub hom phiaj tseem ceeb sab nraud
Ua ntej, cov ntaub ntawv sib txawv thiab qhov ntau thiab tsawg ntawm cov khoom siv laum yuav tsum muaj qhov sib txawv sib txawv thaum drilling rau hauv cov xov xwm sib txawv, txwv tsis pub cov kev ua haujlwm tsis tuaj yeem siv tag nrho. Piv txwv li, 94 hli pob zeb diamond nto mounted laum me ntsis feem ntau yuav tsum muaj qhov tso zis nrawm ntawm 260-600r / min, thaum lub tshuab tho me me yuav tsum muaj qhov tso zis nrawm ntawm 350-700r / min. Kev xaiv yuav tsum yog raws li cov yam ntxwv los txhim kho kev ua tau zoo;
Qhov thib ob, thaum lub sij hawm tsim kho ntawm tag nrho hydraulic drilling rig, cua siab los yog dej siab feem ntau yog siv los yaug hauv qab ntawm lub qhov thiab tso tawm drilling khib nyiab. Txhua qhov nruab nrab muaj nws qhov zoo thiab qhov tsis zoo, thiab tuaj yeem xaiv raws li qhov xav tau. Txawm li cas los xij, thaum siv cov dej slag tso tawm rau qhov drilling ntawm lub kaum sab xis loj (+30 degree lossis ntau dua), cov dej hauv qhov laum pas nrig yuav ntws rov qab vim lub ntiajteb txawj nqus. Nws yuav siv sij hawm ntev los xa cov dej mus rau hauv qab ntawm lub qhov tom qab ntxiv lub laum pas nrig, thiab ntau lub sij hawm xav tau rau qhov tob qhov drilling, uas cuam tshuam rau qhov drilling ceev. Yog li ntawd, yog tias muaj kev tso cai, ib-txoj kev kos valve tuaj yeem muab ntxiv ntawm ob peb lub laum rods kom ntseeg tau tias cov dej slag yuav tsis ntws rov qab thiab txhim kho qhov drilling ceev;
Thib peb, qhov zoo thiab ntws tus nqi ntawm cov kua dej ntws tawm los ntawm cov cuab yeej drilling muaj qee yam cuam tshuam rau qhov drilling ceev. Raws li cov ntaub ntawv muaj nyob hauv pej xeem, qhov viscosity ntawm cov kua dej ntws tawm txo qis, thiab ua kom cov kua dej ntws tawm kuj nce qhov nrawm nrawm. Yog li ntawd, xaiv cov kua dej uas tsim nyog tuaj yeem txhim kho qhov drilling ceev.
