Kev txiav tawm siv cov pob zeb diamond cov khoom siv drilling twj, uas yog lub pob zeb diamond me ntsis. Lub ntsiab zoo ntawm cov pob zeb diamond me ntsis yog tias nws tuaj yeem hloov mus rau strata nrog lub pob zeb siab thiab lub pob zeb nyuaj, thiab muaj kev txiav zoo. Qhov twg ntawm lub qhov tob tho qhov tuam txhab tuaj yeem taw qhia tias nws muaj qhov ua tau zoo nyob rau hauv kev kub ceev drilling.
Raws li qhov sib txawv ntawm qhov tsim nyog, cov khoom tsim pob zeb diamond tuaj yeem muab faib ua ob pawg: cov khoom siv pob zeb zoo tib yam thiab cov pob zeb diamond polycrystalline zoo sib xyaw. Ntawm ob hom no, cov pob zeb diamond zoo tib yam yog qhov tsim nyog rau cov strata nrog lub pob txha siab, lub zog tawv thiab cov geology nyuaj; polycrystalline pob zeb diamond sib xyaw ua ke tuaj yeem siv dav hauv cov strata nyuaj, muag muag muag thiab tawv muag thiab tawv tawv, thiab lawv cov ntawv thov tau dav heev. Qhov sib txawv ntawm rab tuaj yog lub ntsiab sib txawv ntawm ob lub pob zeb diamond.
Polycrystalline pob zeb diamond compact me muaj plaub lub ntsiab, hu ua pob zeb diamond compact, nozzle, matrix thiab lub cev me ntsis. Ordinary lub pob zeb diamond ntsis muaj plaub lub ntsiab, hu ua pob zeb diamond hais, nozzle, txhoj thiab lub cev. Vim tias qhov kev txiav tawm zoo tshaj plaws ntawm cov pob zeb diamond, thaum xaiv cov pob zeb diamond khoom siv raws li cov cuab yeej siv roj, lawv tuaj yeem tho polycrystalline pob zeb diamond ntawm kev kub ceev thiab nthuav qhov tob rau qee yam.
Cov Ntsiab Lus rau Kev Mloog Ntxiv hauv Drilling Ua - Qhov Qhov tob tob ua rau cov neeg lag luam tuaj qhia koj:
Thawj qhov taw tes:
Tom qab siv me ntsis, nws yuav tsum tau kuaj xyuas tam sim rau kev puas tsuaj, passivation thiab lwm yam mob uas tsis tsim nyog. Yog tias muaj ib qho, nws yuav tsum grinded thiab kho tam sim ntawd.
Thib ob taw tes:
Lub ntsis yuav tsum tau zaum thaum nws khaws cia, yog li nws tuaj yeem siv tom qab, uas yooj yim thiab txuag lub sijhawm, thiab txuag lub sijhawm ntawm kev tshawb rau lub ntsis dua.
Thib peb taw tes:
Thaum tho qhov los ntawm lub qhov, thaum lub ntsis tab tom tho qhov dhau, lub torsion yog qhov loj tshaj plaws, yog li nws yuav tsum nkag mus rau cov cuab yeej maj mam nyob rau hauv qhov sib zog kom tsis txhob muaj lub ntsis sib ntswg vim tias muaj zog dhau.
Plaub taw tes:
Ua ntej yuav tho, lub hauv paus taw tes yuav tsum tau muab siv kom nyob rau hauv thiaj li yuav ua kom tau qhov chaw zoo li qub thiab kom tsis txhob muaj lub ntsej muag zoo li kov lub hauv qab ntawm lub ntsis, thiaj li los coj tus ntsis nyob rau hauv txoj haujlwm drilling kom raug.
Thib tsib point:
Thaum tho qhov, qhov txiav yuav tsum tau siv tag nrho thiab nti tshem tawm yuav tsum tau them sai sai rau.
Thib rau taw tes:
Thaum tho qhov qhov hla, lub qhov loj taub yuav tsum tau muab coj ua ntej, thiab tom qab ntawd lub taub me qhov yuav tsum tau muab ua kom.
Thib xya taw tes:
Thaum drilling, qhov tshwm sim ntawm kev tawg lossis nres ceev ceev yog qhov laj thawj ntawm kev noj zaub mov nrawm dhau, ntse los yog kub nrawm thaum lub qhov cub.
