Daim ntawv thov ntawm Tricone Laum khoom hauv ntau hom.

1.Soft Formations

Av nplaum thiab Mudstone Formations:Hlau hniavtricone laum khoomNws yog qhov tsim nyog rau cov qauv mos zoo li av nplaum thiab av nkos vim lawv qhov hardness tsawg. Peb Cones laum Bit tuaj yeem txiav tau yooj yim rau hauv thiab tawg lub pob zeb. Cov duab ntawm cov hniav tuaj yeem tsim los rau khawb thiab txiav, yog li thaum lub sij hawm drilling, lawv ua zoo li lub duav los txhuam cov pob zeb mos. Ntxiv mus, nyob rau hauv cov formations, qhov cuam tshuam quab yuam ntawm lub laum me ntsis yog qhov tsawg, cia cov hniav hlau kom zoo ua rau lub pob zeb tsis muaj hnav ntau dhau.

Sandy Soft Formations:TCI Drill Bits kuj tseem siv tau rau hauv cov xuab zeb tsim nrog cov khoom zoo thiab cov cementation tsis zoo. Nyob rau hauv xws li formations, lub dov ntawm lub khob hliav qab thiab lub shearing txiav txim ntawm cov hniav loosen cov xuab zeb hais, Tricone pob zeb ntsis nqa tawm ntawm lub borehole los ntawm lub drilling kua. Txawm li cas los xij, piv rau cov av nplaum thiab cov av nkos, cov xuab zeb tuaj yeem ua rau qee qhov hnav ntawm cov hniav, yog li kev xaiv ntawm Tricone Rotory Drill Bits yuav tsum nyob ntawm cov yam ntxwv tshwj xeeb ntawm cov xuab zeb (xws li particle loj, hardness, thiab lwm yam). Feem ntau,steel hniav laum khoomtseem tsim nyog.

2.Medium-Hard Formations

Sandstone Formations:Rau sandstone formations, kev xaiv ntawm me ntsis yog nyob ntawm hardness ntawm sandstone. Rau cov cemented nruab nrab thiab nruab nrab nyuaj sandstone, a tungsten carbide insert (TCI) tricone laum ntsisfeem ntau yog qhov kev xaiv zoo tshaj plaws. Cov tawv carbide inserts tuaj yeem tiv taus qhov hnav thiab cuam tshuam los ntawm cov xuab zeb, rhuav tshem nws los ntawm dov ntawm lub khob thiab qhov cuam tshuam thiab crushing ntawm cov hniav. Nyob rau tib lub sijhawm, cov kua dej drilling tawm los ntawm lub nozzles kom txias API tus qauv tricone me ntsis thiab nqa tawm cov pob zeb sandstone tawg, kom ntseeg tau tias cov khoom ua haujlwm zoo.

Limestone Formations:Tungsten carbide ntxig TCI tricone ntsis kuj haum rau limestone formations. Txawm hais tias limestone muaj qee qhov hardness, nws tsis yooj yim rau tawg li cov pob zeb nyuaj heev. Cov carbide inserts zoo ua rau cov limestone los ntawm kev siv cov lus tsa suab ntawm lub khob hliav qab, thov kev cuam tshuam thiab compression. Thaum lub sij hawm drilling, cov dej drilling txias me ntsis, tiv thaiv overheating los ntawm kev sib txhuam thiab nqa cov crushed limestone hais tawm ntawm lub borehole.

3.Qee Hard Formations (nrog qee qhov kev txwv)

Hard Shale Formations:Rau cov qauv shale harder, cov kabmob sib foob rau roj roj dej kom zoo nrog cov ntxeem carbide tuaj yeem ua tau zoo. Cov carbide inserts tuaj yeem cuam tshuam cov shale zoo, thaum lub kaw lus kaw tiv thaiv cov khoom hauv cov dej drilling los ntawm kev nkag mus rau cov bearings, kom ntseeg tau tias lub me me ua haujlwm ruaj khov nyob rau hauv siab dua thiab cuam tshuam lub zog. Txawm li cas los xij, qhov hnav tus nqi ntawm qhov me ntsis yuav nrawm dua hauv cov txheej txheem tawv tawv dua piv rau cov qauv muag muag thiab nruab nrab nyuaj, yog li nws yuav tsum tau saib xyuas qhov Insert Tooth Drill Bit tus mob thiab kho cov sij hawm hloov raws li cov yam ntxwv xws li tsim hardness thiab drilling qhov tob.

Hard Sandstone Formations:Hauv qee qhov nyuaj sandstone formations uas tsis tshua muaj zog, tungsten carbide ntxig tricone laum me ntsis, nrog rau qhov tsim nyog drilling tsis (xws li kev sib hloov ceev, qhov hnyav ntawm me ntsis, thiab lwm yam), tseem tuaj yeem siv tau. Txawm li cas los xij, raws li qhov hardness ntawm cov xuab zeb nce, qhov kev ua haujlwm drilling yuav txo qis, thiab hnav ntawm cov hniav yuav hnyav dua. Nyob rau hauv cov ntaub ntawv no, nws yog ib qho tseem ceeb los saib xyuas qhov me ntsis qhov kev ua tau zoo thiab kho qhov drilling tsis raws li xav tau.
