Kev faib tawm thiab Tus lej ntawm IADC Tricone Bits

The IADCtricone laum ntsis Kev faib tawm thiab kev suav lej yog qhov tseem ceeb rau kev txheeb xyuas thiab nkag siab txog cov yam ntxwv ntawm ntau hom kev xyaum siv hauvroj, roj, thiab dej zoo drilling. Lub system ua haujlwm raws li hauv qab no:

IADC qhia tias txhua yam ntawmpeb tricone ibyog cais thiab suav nrog tus lej plaub tus lej, uas qhia txog tus qauv tsim thiab nws daim ntawv thov hauv ntau hom. Lub ntsiab lus ntawm txhua tus lej yog raws li hauv qab no:

Thawj Zaug: Series Code

Tus lej no, sawv cev los ntawm cov lej 1-8, qhia txog cov yam ntxwv ntawm cov hniav thiab cov tsim uas haum rau me ntsis. Muaj ob hom hniav tseem ceeb siv hauvroj zoo laum khoom: milled hniav thiab ntxig cov hniav (feem ntau hu uaTCI laum khoom los yogTungsten Carbide Insert (TCI) tricone khoom.

1. Milled hniav: Haum rau cov qauv mos uas tsis tshua muaj zog compressive thiab siab drillability. Qhov no yog ib txwm raumilled hniav tricone khoom.
2. Milled hniav: Haum rau nruab nrab mus rau nruab nrab-nyuaj formations nrog siab compressive zog.
3. Milled hniav: Haum rau cov formations nyuaj nrog nruab nrab mus rau siab abrasiveness.
4. Ntxig cov hniav: Haum rau cov qauv mos uas tsis tshua muaj zog compressive thiab siab drillability.
5. Ntxig cov hniav: Zoo tagnrho rau cov mos mus rau nruab nrab-nyuaj formations nrog tsawg compressive zog.
6. Ntxig cov hniav: Tsim rau nruab nrab-nyuaj formations nrog siab compressive zog, feem ntau siv nyob rau hauvTCI tricone khoom.
7. Ntxig cov hniav: Zoo meej rau cov formations nyuaj nrog nruab nrab abrasiveness los yog abrasive yam ntxwv.
8. Ntxig cov hniav: Haum rau cov formations nyuaj heev nrog abrasiveness siab, feem ntau siv rau hauvtungsten carbide tricone laum khoom.

Tus lej thib ob: Lithology Qib Code

Sawv cev los ntawm tus lej 1-4, tus lej no ntxiv subdivides cov formations nyob rau hauv thawj tus lej kev faib tawm los ntawm mos mus rau ib qho nyuaj, xav txog cov kev xav tau tshwj xeeb ntawm qhov drilling.tricone pob zeb.

Tus nab npawb thib peb: Cov qauv me ntsis Feature Code

Tus lej no, sawv cev los ntawm cov lej 1-9, qhia txog qhov me me ntawm cov kabmob thiab ntsuas kev tiv thaiv nta. Cov naj npawb 1-7 yog siv los piav qhia txog cov kabmob thiab kev tiv thaiv feem ntau hauv cov khoom siv rau cov roj, roj, thiab cov dej hauv qhov dej, thaum 8 thiab 9 yog tshwj tseg rau kev tsim kho tshiab yav tom ntej.

1. Tsis-sealed roller bearings
2. Cua txias cov menyuam bearings
3. Cov menyuam bearings nrog ntsuas kev tiv thaiv
4. Sealed roller bearings
5. Sealed roller bearings nrog ntsuas kev tiv thaiv
6. Sealed zawv zawg bearings
7. Sealed zawv zawg bearings nrog ntsuas kev tiv thaiv

Plaub Tus lej: Ntxiv Cov Qauv Txheej Txheem Cai

Tsab ntawv no yog siv los sawv cev cov yam ntxwv ntxiv uas tsis tuaj yeem qhia los ntawm thawj peb tus lej. IADC tau txhais 16 yam ntxwv, xws li cua txias, kev siv lub cev muaj zog, thiab cov duab ntxig tshwj xeeb, uas yuav yog qhov tseem ceeb rau qee yam.peb lub khob laum khoom. Piv txwv ntawm cov yam ntxwv ntxiv muaj xws li:

- A: Cua txias

- B: Tshwj xeeb kaw bearings

- C: Center nozzles

- D: Directional Drilling

- E: Extended nozzles

- G: Kev tiv thaiv kev ntsuas ntxiv thiab kev tiv thaiv lub cev me ntsis

- H: Kab rov tav thiab kev taw qhia kev siv

-J: Nozzle offset

- L: thaub qab stabilizers

- M: Daim ntawv thov lub cev muaj zog

- S: Txheem milled hniav

- T: Ob lub khob hliav qab

- W: Txhim kho cov qauv txiav

- X: Npuag-puab ntxig ntxig

- Y: Conical inserts

- Z: Lwm cov duab ntxig

Thaum twg atricone rotary laum ntsismuaj ntau yam qauv ntxiv, qhov tseem ceeb tshaj plaws yog xaiv los sawv cev los ntawm tsab ntawv code. Cov lej no pab txheeb xyuas qhov rauglaum me ntsis rau kev tshawb nrhiav roj thiab rojthiab xyuas kom meej tias covtricone ibyog qhov zoo tshaj plaws rau qhov tshwj xeeb drilling tej yam kev mob thiab formations ntsib.

Nkag siab txog qhov kev faib tawm ntawm IADC no yog qhov tseem ceeb thaum xaiv ntawmNtxig Hniav Drill Bits(TCI bits) thiabMilled Hniav Tricone Khoomrau qhov sib txawv qhov dej drilling tej yaam num, seb nws yog rau cov roj qhov dej, gas teb, los yog dej zoo drilling hauj lwm.
