Kev piav qhia txog khoom

API tricone bits hauv Tshuag los ntawm Tuam Tshoj tus neeg muag khoom yog ib txwm rau koj qhov kev khawb av zoo dua.
Kev piav qhia ntawm ntsis:
IADC: 517 - TCI phau ntawv xov xwm kaw cov kabmob me me nrog kev tiv thaiv ntsuas rau cov qauv mos mos rau nruab nrab nrog lub zog compressive qis.
Lub zog nias:
85 - 100 MPA
12,000 - 14,500 PSI
Kev piav qhia hauv av:
Cov pob zeb tawv nruab nrab thiab cov pob zeb ntxhib xws li cov xuab zeb xuab zeb uas muaj cov kab quartz, cov pob zeb limestone tawv lossis chert, cov pob zeb hematite, cov pob zeb tawv, cov pob zeb ntxhib uas sib zog zoo xws li: cov xuab zeb xuab zeb uas muaj cov pob zeb quartz binder, dolomites, cov pob zeb quartzite shales, magma thiab cov pob zeb metamorphic coarse grained.
Far Eastern Drilling tuaj yeem muab cov khoom siv laum tricone hauv ntau qhov ntau thiab tsawg (txij li 3 7/8” txog 26”) thiab feem ntau ntawm IADC Codes.

9 7/8 nti (250 hli) yog qhov loj me ib txwm muaj hauv kev khawb qhov tob zoo li kev khawb roj thiab roj av, thiab nws kuj yog qhov loj me ib txwm muaj hauv kev khawb qhov kab rov tav.
Nyob ntawm cov khoom siv txiav, cov ntsis laum roj hmab silicone muaj nyob rau hauv TCI (carbide insert) thiab cov hniav hlau. iADC517 yog TCI hom laum roj hmab silicone.

Cov qauv kabmob.
Cov kabmob phau ntawv qhia kev kub siab nrog ob qhov chaw thawb, lub khob hliav qab xauv pob, qhov chaw tawv ntawm lub taub hau kabmob, lub khob hliav qab kabmob inlaid nrog cov hlau txhuam txo kev sib txhuam thiab tom qab ntawd plated nyiaj, uas ua kom zoo dua qhov kev tiv thaiv kev hnav thiab kev tiv thaiv galling ntawm cov kabmob thiab yog tsim rau kev kub ceev.

Sealing thiab lubrication.
Cov pob khoom siv hlau nplaum siab heev muaj ob lub foob hlau thiab ob lub roj hmab nplaum uas ruaj khov. Cov roj hmab nplaum uas nruj nruj ua kom muaj kev sib cuag zoo ntawm ob qhov chaw sib khi ntawm cov nplhaib hlau los ntawm lub zog elastic kom ua tiav kev sib khi ntawm cov kabmob. Thaum khawb, cov foob hlau yog qhov sib txawv thaum cov roj hmab nplaum yog static, uas yuav txhim kho kev ntseeg tau thiab kev ruaj khov ntawm cov foob kabmob, thaum lub kaw lus them nyiaj siab thiab roj nplaum siab heev tuaj yeem txhim kho kev ntseeg tau ntawm kev siv lubrication.
