1. Kev Taw Qhia Txog Hnyav Hnyav Cov Yeeb Nkab
Cov kav dej laum yog cov khoom tseem ceeb txuas cov khoom siv saum npoo rau cov cuab yeej downhole.Heavy Weight Drill Pipes (HWDP), raws li cov kav dej tshwj xeeb laum, ua haujlwm raws li kev hloov pauv ntawm cov txheej txheem laum cov kav dej thiab laum dab tshos. Los ntawm kev txhim kho cov qauv tsim thiab cov khoom siv siab heev, HWDP ua lub luag haujlwm tseem ceeb hauv kev thauj khoom, kev co damping, thiab zoo trajectory stabilization nyob rau hauv complex drilling tej yam kev mob.
Cov yam ntxwv tseem ceeb:
Kev hloov ntawm tus qauv: Txuas cov kav dej "flexible" laum thiab "rigid" laum dab tshos, mitigating stress concentration ntawm junctions.
Txhim kho phab ntsa Thickness: 2-3 lub sij hawm tuab dua li cov kav dej raws li tus qauv thaum tuav tib txoj kab uas hla (piv txwv li, φ50 mm, φ89 mm) rau kev ua haujlwm tau zoo.
Multifunctional Applications: Hloov cov hlua tho hauv qhov slim-qhov drilling, txo cov torque thiab daig yeeb nkab txaus ntshai nyob rau hauv cov qhov dej taw qhia, thiab ua kom muaj qhov hnyav-rau-ntsis (WOB) tswj.
2. Kev tsim qauv: Dual Assurance ntawm lub zog thiab hnav tsis kam
2.1 Pipe Lub cev qauv

2.3 Hnav-Resistant Hardbanding
Khoom sivKhoom siv: Tungsten carbide (HRC ≥60)
Muaj nuj nqi: Txo cov yeeb nkab lub cev hnav los ntawm 50% hauv cov qhov dej kab rov tav.
Txhim khu kev sib txhuam rau laum txoj hlua stabilization thiab tswj trajectory.
3. Core Functions: Los ntawm Kev Txo Kev Nyuaj Siab mus rau Wellbore Stability
3.1 Kev ntxhov siab tsis zoo
Vibration Absorption: Cov kev ntxhov siab thiab cov ntaub ntawv elastic hloov lub tsho dab tshos rau hauv elastic zog dissipation.
Torque Damping: Extended cuab yeej pob qij txha redistribute torsional stresses, minimizing qaug zog tsis ua hauj lwm nyob rau hauv tus qauv kav.
3.2 WOB Optimization
Nyhav Advantage: Qhov hnyav nruab nrab (piv txwv li, 38 kg / m rau φ89 mm HWDP) nruab nrab ntawm cov kav dej thiab dab tshos.
Adaptive Control: Kho WOB rau shale formations (tiv thaiv cov yeeb nkab daig) thiab cov txheej pob zeb nyuaj (txhim kho qhov nkag).
3.3 Trajectory thiab Wellbore Integrity
Directional Stability: Hardbanding minimizes laum txoj hlua wobble, tswj txoj kev npaj zoo.
Anti-Collapse: Txo cov kev kub ntxhov hauv zos los ntawm kev khoov, thaum cov av nkos ua kom lub qhov huv huv.
4. Kev siv tswv yim
4.1 Ultra- Deep Well Drilling
Case Study: Tashen-1 Well (8,408 m qhov tob,> 200 ° C, 140 MPa siab).
Kev ua tau zoo: High-temperature-resistant alloys thiab chim siab designs overcame abrasive formations thiab cyclic stresses.
4.2 Kev Nyuaj Siab Geological Conditions
Ntsuag roj ib puag ncig: Jiaoye-1HF Zoo (Fuling Shale Gas Field) siv cov khoom siv corrosion-resistant thiab coatings los tiv thaiv H₂S.
Directional / Kab rov tav Wells: Spiral-type HWDP txo kev sib txhuam thiab txhim kho kev tswj xyuas.
5. Kev Txhim Kho Kev Lag Luam
5.1 Manufacturing Innovations
Kev kho cua sov: quenching thiab tempering los txhim kho kev cuam tshuam toughness.
Quality Assurance: 100% ultrasonic kuaj (UT) thiab magnetic particle soj ntsuam (MPI).
5.2 Smart Manufacturing
Kev sib koom ua ke ntawm MES / ERP: Tag nrho cov txheej txheem traceability los ntawm kev txiav txim mus rau tus me nyuam.
Customization Options: Kev sib txuas ob lub xub pwg nyom, txuas ntxiv hardbanding, thiab cov txheej txheem yas sab hauv.
6. Cov txheej txheem tsim khoom
Kev xaiv khoom: 4145H MOD alloy steel tuav.
Kev ua yeeb nkab: Drilling → chim siab forging → tshav kub kho.
Tool Joint Fabrication: Forging → xov txias dov → phosphating.
Vuam / Kev sib dhos: Kev sib txhuam welding lossis ib qho kev ua haujlwm.
Kev Tswj Xyuas Zoo: UT thickness ntsuas, hardness kuaj, siab validation.
Kev kho saum npoo: Hardbanding daim ntawv thov thiab anti-corrosion txheej.
Xaus
Raws li lub hauv paus ntawm cov cuab yeej siv niaj hnub drilling, HWDP muab cov qauv kev tsim kho tshiab thiab cov khoom siv tshawb fawb los txhim kho kev nyab xeeb thiab kev ua haujlwm zoo. Los ntawm cov qhov dej tob tob mus rau corrosive formations, nws ob lub luag hauj lwm raws li "kev hloov pauv hloov" thiab "kev txhawb nqa nruj" txuas ntxiv thawb cov ciam teb ntawm kev tshawb nrhiav roj thiab roj.
