S135 laum yeeb nkab yog lub zog siab tshaj plaws qib laum yeeb nkab steel hauv API Spec 5DP tus qauv (tsawg kawg yield zog 135ksi / 931MPa), ua tiav qhov sib npaug ntawm lub zog thiab tawv los ntawm microalloying tsim thiab TMCP (thermomechanical tswj txheej txheem). Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev ua haujlwm hnyav xws li ultra- qhov tob tob tshaj 8000 meters thiab txuas mus txog qhov dej, thiab cov khoom siv no yog siv hauv 90% ntawm ultra- qhov dej tob tob thoob ntiaj teb.
S135 Laum Pipe Specification
Cov khoom tseem ceeb lossis qib hlau: API: E75, X95, G105, S135
Cov Qauv Khoom: API SPEC 5DP
Khoom nta:
(1) Thaum ua kom muaj zog, nws kuj muaj qhov zoo toughness thiab siab torsional zog, muaj peev xwm tiv taus lub zog sab hauv thiab sab nraud, torsion, khoov, thiab kev co;
(2) Nws muaj weldability zoo;
(3) Cov khoom muaj qhov siab qhov tseeb, nrog kev ncaj nce mus txog 1mm / m.
Khoom Specification Range
Sab nraud txoj kab uas hla: Φ60.32mm ~ Φ168.28mm;
Phab ntsa Thickness: 7.11mm ~ 12.7mm.
Tsib Core Functions ntawm S135 Laum Pipe:
1. Fais fab kis: xa cov kev sib hloov quab yuam thiab downforce ntawm qhov chaw drilling rig mus rau lub laum me ntsis. Piv txwv li, hauv kev ua haujlwm sib sib zog nqus, cov yeeb nkab laum yuav tsum tiv taus axial loads tshaj 500 kN;
2. Drilling Fluid Delivery: Circulates siab - siab drilling kua kom txias lub laum me ntsis thiab nqa cuttings. Tsis txaus txaus tus nqi tuaj yeem ua rau hauv qab qhov kub siab tshaj 200 degree;
3. Wellbore Trajectory Control: Siv tau yooj yim laum yeeb nkab (xws li, 5℃/ 30m khoov) ua kom muaj kev taw qhia meej hauv cov qhov dej kab rov tav;
4. Cov ntaub ntawv xa tawm: Kev Ntsuas Thaum Drilling (MWD) system xa cov ntaub ntawv tiag tiag - lub sij hawm downhole cov ntaub ntawv los ntawm cov yeeb nkab laum lub puab qhov tho;
5. Kev Nyab Xeeb Kev Nyab Xeeb Channel: Nyob rau hauv qhov xwm txheej ntawm lub tshuab hluav taws xob, tua cov kua dej tuaj yeem raug txhaj los ntawm cov yeeb nkab laum, nrog lub sijhawm teb sai li 15 feeb.
