Revolutionizing Drilling: Advanced Bit Solutions.
Kev sib xyaw thiab cov khoom Series ntawm API Standard Tricone Bits
1. Cheebtsam ntawmTricone Pob Zeb Khoom
Tricone laum khoom yog tsim los ntawm tsib qhov tseem ceeb: lub laum lub cev, ceg, cones, bearing, thiab nozzle. Rau cov khoom siv dav hlau kaw, lawv kuj suav nrog lub tshuab lubrication thiab them nyiaj.
2. Series ntawm Tricone Drill Bits
① Diameter Series ntawmTricone Drill Bits
Domestic Drill Bits: Cov kab kab kab uas hla suav nrog 15 qhov ntau thiab tsawg. Feem ntau siv los ntawm Kingdream yog 17 1/2", 12 1/4", 9 5/8",8 1/2 ", thiab 3 7/8 ".
Imported Drill Bits: Txoj kab uas hla yog ntau dua. Piv txwv li, laum khoom los ntawm US-based Hughes Company npog 46 qhov ntau thiab tsawg xws li 3 3/4 "rau 26".
② Coding ntawm Kingdream Roj Tricone Khoom
- Tus qauv code muaj plaub ntu:
- Bit Diameter Code: Sawv cev hauv ntiv tes, tag nrho lossis feem.
- Series Code: Qhia txog cov yam ntxwv tseem ceeb ntawm cov kabmob thiab cov qauv sib khi rau Peb Lub Taub Hau Drill Bit, muab faib ua cuaj pawg.
- Classification Code: Peb tus lej nyob qhov twg:
- Thawj tus lej yog hais txog kev txiav cov qauv thiab kev tsim series.
- Tus lej thib ob qhia txog qib tsim.
- Tus lej thib peb qhia txog cov yam ntxwv ntawm qhov me ntsis.
- Ntxiv Cov Qauv Txheej Txheem: Rau cov kev cai tshwj xeeb, kev hloov kho tau sau nrog ib lossis ntau tsab ntawv raws li kev faib cov cai.
Piv txwv:
- 8 1/2 ": Txoj kab uas hla ntawm me ntsis.
- HJT: zawv zawg bearings nrog hlau foob thiab ntsuas tshwj xeeb tiv thaiv.
- 537: Tsawg compressive zog, mos mus rau nruab nrab formations, TCI Tricone ntsis.
- G: Muaj zog ceg.
3. Xaiv cov khoom Tricone
Qhov kev xaiv yog nyob ntawm cov ntaub ntawv los ntawm cov qauv zoo sib xws hauv cov qhov dej nyob sib ze, tsim cov xwm txheej, thiab cov xwm txheej tshwj xeeb ntawm qhov dej. Xav txog:
- Formation hardness thiab abrasiveness.
- Qhov tob ntawm qhov drilled seem.
- Inclined formations yuav tsum tau anti-deviation drilling.
- Alternating nyuaj thiab mos formations.
4. Kev txiav txim Tricone ntsis Cov xwm txheej Downhole
① Ua haujlwm li qub:
Nrog rau kev tsim cov lithology zoo ib yam, lub rooj sib hloov ntawm lub rooj sib txawv yog qhov sib txawv, qhov kev sib tsoo ceev tseem nyob ruaj khov, thiab cov ntsuas ntsuas ntawm qhov ntsuas siab tsis tu ncua.
② Cov kabmob tsis ua haujlwm:
Periodic stick-slip txav ntawm lub rooj teb, txo kev xyaum nrawm, thiab hloov qhov hnyav-rau-ntsis nyeem ntawv.
③ Cone Xauv:
Kev ua kom muaj zog ntau dua, hnyav nplaum nplaum, thiab nyuaj rau kev tig txoj hlua tho.
④Dropped Cone:
Qhov tseem ceeb rotary load nce, abrupt stick-slip txav, thiab txo tus nqi nkag los yog tsis muaj kev vam meej drilling.
⑤ Hniav Hniav:
Lub teeb rotary load, txo qhov nkag mus, thiab ntsuas ntsuas ntsuas ntsuas ntsuas ntsuas.
⑥ Ntsis Balling:
Nce rotary load, txo qhov nkag mus, thiab siab twj tso kua mis siab.
Pob zeb diamond thiabPDC Drag Bits
1. Cov qauv ntawm pob zeb diamond laum khoom
- Ntuj Pob Zeb Drill Bits: Ua los ntawm lub cev steel, matrix, nozzle, thiab pob zeb diamond hais.
- PDC Cutter Laum khoom: suav nrog lub cev steel, matrix, nozzle, thiab polycrystalline pob zeb diamond cutters.
① Profile duab
PDC rub cov khoom muaj peb daim duab:
- Parabolic: Tsim nyog rau cov qauv mos, muab kev kub ceev drilling thiab ruaj khov.
- Circular: Zoo tagnrho rau cov tawv interlayers vim muaj concentrated hydraulics.
- Conical: Tsim kom muaj zog nkag mus thiab ruaj khov hauv kev ua haujlwm siab.
②Bit Xaiv
Xav txog yam xws li txoj kev drilling, hom kev tsim, thiab cov kev tsis sib xws thaum xaiv PDC Drag Bit.
③ Cov txheej txheem siv kom raug
- Tswj lub twj tso kua mis siab tshaj 13 MPa.
- Tsis txhob sib tsoo nrog cov khoom tawv thiab muaj kev cuam tshuam sai thaum lub sijhawm drilling.
- Ntxuav lub qhov dej hauv qab kom huv si ua ntej pib ua haujlwm.
- Siv qhov ntsuas qhov zoo tshaj plaws: qhov hnyav-rau-ntsis (30-60 KN), rotary ceev (117-217 RPM).
3. Coring Drill Bits
Coring laum khoom yog tsim los rau annular crushing kom rho tawm pob zeb cores. Cov hom muaj xws li rub cov khoom, tungsten carbide core khoom, thiab pob zeb diamond core khoom. Cov yam ntxwv xws li symmetry thiab hnav tsis kam ua kom cov tub ntxhais rov qab zoo siab.
