Cias muab, lubHauv qab qhov sib dhos (BHA)yog qhov tseem ceeb tshaj plaws ntawm qhovLaum hlua.
Txoj hlua laum yog hais txog tag nrho cov kab ntawm cov yeeb nkab txuas txuas los ntawm cov rig hauv pem teb mus rau lub laum me ntsis - muaj cov laum yeeb nkab, hnyav - hnyav laum yeeb nkab, thiab BHA- feem ntau yog siv los ua cov kav dej rau cov dej ntws thiab xa hluav taws xob; conversely, BHA yog qhov hnyav -lub luag hauj lwm seem nyob ncaj qha saum lub ntsis- muaj xws li laum dab tshos, stabilizers, jars, thiab lwm yam cuab yeej- tshwj xeeb engineered los muab nyhav rau ntsis (WOB), tswj lub qhov dej trajectory, thiab tiv thaiv cov yeeb nkab buckling nyob rau hauv compressive loads.

Heavy Weight Drill Pipe (HWDP) Specification
HWDP yog siv los ua ib qho kev hloov pauv ntawm cov yeeb nkab laum thiab cov dab laum los txo cov kev ntxhov siab thiab muab qhov hnyav ntxiv ntawm me ntsis.
| OD (Inches) | Sab hauv Diameter (ID) | Nominal Nyhav (lb/ft) | Khoom siv | Kev sib txuas |
| 3-½" | 2-¼" | 25.3 | AISI 4145H | NC 38 (3-½ "IF) |
| 4-½" | 2-¾" | 41.0 | AISI 4145H | NC46 (4" IF) |

| 5-½" | 3-¼" | 57.0 | AISI 4145H | 5- ½ "FH |
Drill Collar Specification
Nyob rau hauv qab ntawm txoj hlua, laum dab tshos siv lawv qhov hnyav los muab qhov hnyav ntawm ntsis (WOB) thiab muab rigidity rau lub laum me ntsis.
| OD (Inches) | ID (Inches) | Qhov hnyav (lb / ft) | Kev sib txuas | Hom |
| 4-¾" | 2-¼" | 47 | NC 35 (3-½ "IF) | Slick / Kauv |
| 6-½" | 2-13/16" | 92 | NC46 (4" IF) | Slick / Kauv |
| 8" | 2-13/16" | 150 | 6-⅝ "Regular | Slick / Kauv |
| 9-½" | 3" | 215 | 7-⅝ "Regular | Slick / Kauv |
BHA - Hauv qab Qhov Rooj Sib Tham (Lub Lag Luam Kawg)
CovBHAyog qhov qis dua ntawm txoj hlua xyaum, nyob ncaj qha saum lub laum me ntsis. Nws yog ua los ntawm ntau qhov hnyav, tuab, thiab cov cuab yeej tshwj xeeb tshaj li cov qauv tho yeeb nkab.
Cheebtsam:Drill Collars, Stabilizers, Mud Motors, Jars, thiab MWD/LWD (Directional sensors).
Ntev:Feem ntau tsuas yog ob peb puas mus rau ib txhiab ko taw ntev.
Txoj hauj lwm tseem ceeb:
Los muabQhov hnyav ntawm ntsis (WOB)yog li qhov me me tuaj yeem tsoo pob zeb.
Txhawm rau kom lub qhov ncaj los yog coj nws mus rau hauv ib qho kev taw qhia tshwj xeeb.
Txhawm rau tiv thaiv cov yeeb nkab tho nyias saum toj ntawm buckling.

FAQ
Dab tsi yog BHA hauv qhov drilling?
Hauv qhov drilling, aHauv qab qhov sib dhos (BHA)yog qhov qis dua ntawm txoj hlua xyaum, nyob ncaj nraim saum lub laum me ntsis, uas muaj cov khoom hnyav -cov cuab yeej xws li laum dab tshos, stabilizers, jars, thiab sensors (MWD/LWD). Nws yog tshwj xeeb engineered los muab cov concentrated hnyav (Qhov hnyav ntawm ntsis) yuav tsum tau crushed los ntawm pob zeb formations, tswj kev ruaj ntseg kom lub wellbore ncaj, thiab muab kev taw qhia kev tswj kom steer me ntsis raws li ib tug tshwj xeeb txoj kev mus rau lub reservoir.
Dab tsi yog ib txoj hlua tho?
A xyaum txoj hluayog ib kab ntev, txuas ntxiv ntawm cov kav hlau txuas thiab cov cuab yeej tshwj xeeb uas ncab los ntawm qhov drilling rig ntawm qhov chaw mus rau qhov xyaum me ntsis hauv qab ntawm lub qhov dej. Nws ua raws li lub zog xa hluav taws xob uas hloov pauv kev sib hloov thiab lub zog mus rau qhov me me, ua haujlwm siab - cov kav dej siab rau cov dej ntws ntws tawm, thiab muab qhov hnyav hnyav (Nruab Ntsis) tsim nyog rau me ntsis kom zoo crush thiab txiav los ntawm pob zeb formations.
