Roj av casingsyog cov cuab yeej tseem ceeb rau kev ua haujlwm roj, nrog rau cov khoom tseem ceeb xws li cov kav dej tho, cov kav dej, cov kav dej, cov hlua tho, thiab cov kav dej me me. Cov khoom tsim hauv tsev yog tsim los ntawm geological laum hlau uas dhau los ua cov txheej txheem kub dov lossis txias txheej txheem. Cov qib steel raug xaiv nrog cov npe "DZ", thiab feem ntau siv cov qib steel xws li DZ40, DZ55, thiab DZ75.
Daim ntawv thov
Siv nyob rau hauv cov roj zoo drilling ua haujlwm.
Hom
Raws li SY/T6194-96 "Petroleum Casing", muaj ob hom: luv-xov nrog couplings thiab ntev-threaded nrog couplings.
Specifications thiab Surface Quality
(1) Rau SY/T6194-96, nyob hauvRoj av casingsmuaj qhov ntev tsis sib xws ntawm 8-13m, tab sis luv dua 6m tuaj yeem muab tsis pub tshaj 20% ntawm tag nrho cov khoom.
(2) Sab hauv thiab sab nrauv yuav tsum tsis pub dawb los ntawm laps, seams, laminations, tawg, qhab nia, thiab tuag. Cov teeb meem no yuav tsum tau muab tshem tawm tag nrho, nrog rau qhov tob tsis tshaj 12.5% ntawm nominal phab ntsa thickness.
(3) Lub coupling sab nrauv yuav tsum tsis txhob muaj laps, seams, laminations, tawg, qhab nia, los yog tuag marks.
(4) Lub casing thiab coupling xov nto yuav tsum du, tsis muaj burrs, kua muag, los yog lwm yam tsis xws luag uas yuav cuam tshuam cov xov, cuam tshuam lub zog thiab ruaj ntseg kev twb kev txuas.
Chemical Composition Test
(1) Ib SY/T6194-96, casings thiab couplings siv tib qib steel nrog sulfur Tsawg dua lossis sib npaug rau 0.045% thiab phosphorus Tsawg dua lossis sib npaug rau 0.045% .
(2) Cov tshuaj ntsuam xyuas cov qauv coj mus rau ib GB 222-84, nrog rau kev tshuaj ntsuam xyuas tshuaj raws li GB223 seem.
(3) Raws li API Spec 5CT 1988 1st Edition, cov qauv tshuaj ntsuam xyuas tshuaj tau npaj ib qho tshiab ASTM E59, nrog kev tshuaj xyuas ib qho tshiab ASTM E350.
Kev kuaj lub cev
(1) Raws li SY/T6194-96, kev sim flattening (GB246-97), tensile tests (GB228-87), thiab hydrostatic tests ua.
(2) Ib API Spec 5CT 1988 1st Ed., hydrostatic, flattening, sulfide stress cracking, hardness (latest ASTM E18 los yog E10), tensile, Charpy cuam tshuam (kawg ASTM A370, E23 thiab lwm yam), grain loj ( ASTM E112 los yog lwm yam) xeem tau ua.
Ntsiab Ntshuam / Export Summary
(1) Lub teb chaws loj casing ntshuam: Lub teb chaws Yelemees, Nyiv, Romania, Czech koom pheej, Ltalis, UK, Austria, Switzerland, USA; ib co los ntawm Argentina, Singapore. Imports feem ntau siv API 5A, 5AX, 5AC nrog qib steel H-40, J-55, N-80, P-110, C-75, C{{ 9}} thiab lwm yam. Qhov ntau thiab tsawg xws li 139.7, 177.8, 244.5 mm OD.
(2) API specifies three length ranges: R-1 4.88-7.62m, R-2 7.62-10.36m, R-3 >10.36m.
(3) Qee qhov kev xa khoom tau cim "LTC" rau cov xov txuas ntev.
(4) Cov khoom lag luam Nyij Pooj qee zaum siv cov qauv tsim xws li NC-55E, NC-80E thiab lwm yam los ntawm cov zeb xws li Nippon Steel, Sumitomo, Kawasaki.
(5) Cov ntaub ntawv thov tau cuam tshuam nrog kev puas tsuaj xws li cov xov puas / couplings, kev sib tsoo, kev sib txuas sib txuas, kev cuam tshuam xov tsis zoo, kev sib txuas tsis raug J ntsuas, nrog rau cov teeb meem tshwm sim xws li brittleness, tsis muaj zog yield.
Lwm yam
Raws li API Spec 5CT 1988 1st Ed.,Roj av casingsteel qib muaj xws li H-40, J-55, K-55, N-80, C-75, L-80, C{{6} }, C-95, P-110, Q-125.
Casings muab nrog threads thiab couplings, los yog nrog cov kawg hom:
Plain kawg, round threads nrog / tsis muaj couplings, buttress threads nrog / tsis muaj couplings, flush sib koom threads, tshwj xeeb kawg preps, foob nplhaib tsim.
