Cov khoom siv rau cov menyuam IADC637 9 7/8” (250.8mm)
Kev piav qhia txog khoom
Lag luam wholesale API TCI tricone laum ntsis nrog luv nqi hauv Tshuag los ntawm Tuam Tshoj Hoobkas rau cov qauv nyuaj.
Kev piav qhia ntawm ntsis:
IADC: 637 - TCI phau ntawv xov xwm kaw cov kabmob me me nrog kev tiv thaiv ntsuas rau cov qauv nruab nrab nrog lub zog compressive siab.
Lub zog nias:
100 - 150 MPA
14,500 - 23,000 PSI
Kev piav qhia hauv av:
Cov pob zeb tawv, zoo-compacted xws li: nyuaj silica limestones, quarzite streaks, pyrite ores, hematite ores, magnetite ores, chromium ores, phosphorite ores thiab granites.
Far Eastern Drilling tuaj yeem muab cov khoom siv TCI hauv ntau qhov ntau thiab tsawg (txij li 3 3/8 "txog 26") thiab feem ntau ntawm IADC cov lej.
9 7/8" yog 250 hli hauv txoj kab uas hla, qhov kev sib txuas xov yog 6 5/8 reg pin raws li API specification.
IADC537 txhais tau hais tias tricone roller bit yog qhov tsim nyog rau kev khawb cov pob zeb tawv xws li quarzite streaks, granites, thiab lwm yam. Cov kabmob yog elastomer kaw kom ua rau lub neej ua haujlwm ntev dua.
Tungsten carbide inserts (TCI) yog cov hlau nyuaj heev rau kev khawb cov pob zeb tawv, lub pob taws ntawm lub cones thiab caj npab-rov qab yog tag nrho ntxig nrog Tungsten Carbide hniav.
Nws yog ib qho loj me uas siv ntau hauv kev khawb av, rau kev khawb qhov tawg. Hauv kev khawb av, tus lej thawj zaug rau IADC code feem ntau yog 6, 7, 8, thiab tus lej thib peb feem ntau yog 2 thiab 5.
Raws li IADC cov lus qhia rau tricone ntsis, "2" txhais tau tias tus qauv qhib bearing roller bit, thiab "5" txhais tau tias kaw cov menyuam bearing bit nrog gauge tiv thaiv.
Hauv qee lub tebchaws, 9 7/8 "(250.8mm) feem ntau yog siv los tho qhov dej thiab qhov dej geothermal. Lub tshuab tho qhov dej yog ncig los ntawm cov kua av nkos, es tsis txhob nias cua.
Yog li ntawd, rau ntau daim ntawv thov sib txawv, peb yuav tsum xaiv cov khoom siv tricone roller kom raug.

Far Eastern yog lub Hoobkas tshwj xeeb hauv kev siv cov khoom siv laum, xws li cov khoom siv tricone, cov khoom siv PDC, lub tshuab qhib qhov HDD, lub tshuab txiav rau ntau yam kev siv sib txawv. Daim ntawv thov suav nrog cov roj av, roj av ntuj, kev tshawb nrhiav geological, kev tho qhov, kev khawb av, kev khawb dej qhov dej, HDD, Kev tsim kho thiab kev tsim kho hauv paus...
Ua ib lub Hoobkas ua cov khoom siv laum hauv Suav teb, peb lub hom phiaj yog ua kom lub neej ua haujlwm ntawm cov laum ntev dua. Peb ib txwm sim txhim kho cov khoom siv uas muaj kev nkag mus tob dua. Peb lub hom phiaj yog txo tus nqi ntawm kev laum ib 'meter'. Peb lub hom phiaj yog muag cov khoom zoo nrog tus nqi qis tshaj.
