Ntchito zopangira mafuta:

Amagwiritsidwa ntchito pobowola bwino mafuta amagwiritsidwa ntchito kwambiri pobowola komanso pambuyo pomaliza chithandizo cha khoma la chitsime, pofuna kuonetsetsa kuti pobowola ndi ntchito yabwino ya chitsime chonsecho chitatha. kupsinjika maganizo ndizovuta, ndipo machitidwe athunthu a kugwedezeka, kuponderezana, kupindika ndi kupsinjika kwa torsional pa thupi la chitoliro kumayika patsogolo zofunikira za khalidwe la casing palokha. imawonongeka chifukwa chazifukwa zina, imatha kupangitsa kuti chitsime chonsecho chichepetse, kapenanso zinyalala.

Mitundu ya botolo la mafuta:

Malinga ndi SY/T6194-96 "petroleum casing", ikhoza kugawidwa m'mitundu iwiri: chokopa chachifupi chokhala ndi ulusi ndi kolala yake ndi casing yayitali ndi kolala yake.

Muyezo wa posungira mafuta ndi ma CD:

Malingana ndi SY/T6194-96, chotchinga chapakhomo chiyenera kumangiriridwa ndi waya wachitsulo kapena lamba wachitsulo. Mbali yowonekera ya casing iliyonse ndi ulusi wa kolala iyenera kukulungidwa ndi mphete yotetezera kuteteza ulusi.

Chophimbacho chidzaperekedwa ndi ulusi ndi kolala molingana ndi API SPEC 5CT1988 kope loyamba kapena mwanjira iliyonse yomaliza ya chitoliro: mapeto athyathyathya, ulusi wozungulira wopanda kolala kapena kolala, kuchotsa ulusi wa trapezoidal kapena wopanda kolala, ulusi wowongoka, mapeto apadera , kupanga mphete yosindikizira.

Chitsulo chachitsulo chamafuta a petroleum:

Oil casing zitsulo kalasi akhoza kugawidwa m'magulu osiyanasiyana zitsulo malinga ndi mphamvu ya zitsulo palokha, monga H-40, J-55, K-55, N-80, C-75, L-80, C-90, C -95, P-110, Q-125, ndi zina zotero.Kusiyanasiyana kwabwino, kuya kwakuya, kugwiritsa ntchito kalasi yachitsulo kumakhalanso kosiyana.Chombocho chimafunikanso kuti chisawonongeke m'malo owononga.M'malo omwe ali ndi zovuta za geological, casing imafunikanso kugonjetsedwa ndi kuphwanya.

Njira yowerengera kulemera kwa chosungira mafuta ndi motere:

KG/ m = (m'mimba mwake wakunja - makulidwe a khoma) * makulidwe a khoma * 0.02466

Utali wa botolo la mafuta:

Pali mitundu itatu yautali wotchulidwa ndi API: R-1 4.88 mpaka 7.62m, R-2 7.62 mpaka 10.36m, R-3 10.36m mpaka kutalika.

Mtundu wa buckle wa petroleum:

API 5CTMitundu ya zomangira zamafuta a petroleum imaphatikizapo STC (chingwe chozungulira chachifupi), LTC (chingwe chozungulira chachitali), BTC (chomangira chapang'ono cha makwerero), VAM (king buckle) ndi mitundu ina.

Kuyang'anira magwiridwe antchito a petroleum casing:

(1) Malinga ndi SY/T6194-96.Kuchita mayeso a flattening (GB246-97) tensile test (GB228-87) ndi hydrostatic test.

(2) hydrostatic test, flattening test, sulfide stress corrosion cracking test, hardness test (ASTME18 kapena E10 version yaposachedwa), kuyesa kwamphamvu, kuyesa kopitilira muyeso (ASTMA370, ASTME23 ndi mtundu waposachedwa wa miyezo yoyenera) molingana ndi zomwe American Petroleum Institute APISPEC5CT1988 kope loyamba Ok), kutsimikiza kwa kukula kwambewu (ASTME112 mtundu waposachedwa kapena zina njira)

Kulowetsa ndi kutumiza kunja kwa botolo la mafuta:

(1) Mayiko ofunikira kwambiri opangira mafuta ndi awa: Germany, Japan, Romania, Czech Republic, Italy, United Kingdom, Austria, Switzerland, United States, Argentina, Singapore komanso kuitanitsa.Miyezo yolowetsamo imatchula muyeso wa American Petroleum Institute API5A, 5AX, 5AC.Steel giredi ndi H-40, J-55, N-80, P-110, C-75, C-95 ndi zina zotero.Mafotokozedwe akuluakulu ndi 139.77. 72R-2, 177.89.19R-2, 244.58.94R-2, 244.510.03R-2, 244.511.05r-2, ndi zina zotero.

(2) Pali mitundu itatu yautali wotchulidwa ndi API: R-1 ndi 4.88 ~ 7.62m, R-2 ndi 7.62 ~ 10.36m, R-3 ndi 10.36m kutalika.

(3) Gawo lazinthu zomwe zatumizidwa kunja zimalembedwa ndi LTC, mwachitsanzo, malaya amtundu wa filament.

(4) Kuphatikiza pa miyezo ya API, ma bushing ochepa omwe amatumizidwa kuchokera ku Japan amatsatira miyezo ya opanga ku Japan (monga Nippon Steel, Sumitomo, Kawasaki, etc.), manambala achitsulo ndi NC-55E, NC-80E, NC. -L80, NC-80HE, etc.

(5) Pazifukwa zodzinenera, panali zolakwika zowoneka ngati zotchingira zakuda, kuwonongeka kwa waya, kupindika kwa thupi la chitoliro, zomangira zosweka ndi ulusi wotalikirana ndi kulolerana, kuphatikiza mtengo wa J chifukwa cha kulolerana, ndi zovuta zamkati zamkati monga kuwonongeka kwamphamvu. ndi mphamvu zochepa zokolola za casing.
