Mashandisirwo ekuisa mafuta mubhokisi:

Inoshandiswa pakuchera matsime emafuta inonyanya kushandiswa pakuchera uye mushure mekupedzwa kwekutsigira madziro etsime, kuitira kuve nechokwadi chekuti tsime rese rinoitwa zvakanaka uye kushanda kwaro kwakajairika mushure mekupedzwa. Nekuda kwemamiriro akasiyana enzvimbo, mamiriro ekumanikidzwa kwepasi pevhu akaoma, uye kushanda kwakazara kwekumanikidzwa, kudzvanywa, kukotama uye kutenderera kwepombi kunoita kuti pave nezvinodiwa zvepamusoro zvemhando yebhokisi pacharo. Kana bhokisi pacharo rakuvara nekuda kwechimwe chikonzero, zvinogona kutungamira kudzikira kwekugadzirwa kwetsime rese, kana kutoti marara.

Mhando dzemabhokisi emafuta:

Zvichienderana neSY/T6194-96 "petroleum casing", inogona kukamurwa kuita mhando mbiri: kaburi kapfupi kane shinda uye kora yaro uye kaburi karefu kane shinda uye kora yaro.

Chiyero chekuvhara mafuta uye kurongedza:

Sekureva kweSY/T6194-96, chivharo chemumba chinofanira kusungwa newaya yesimbi kana bhandi resimbi. Chikamu chakavhurika chechivharo chimwe nechimwe neshinda yekora chinofanira kuputirwa nerin'i yekudzivirira kuchengetedza shinda.

Chivharo chinofanira kupihwa shinda nekora zvichienderana neAPI SPEC 5CT1988 first edition kana mune chero ipi yemhando dzemapombi anotevera: magumo akatsetseka, tambo yakatenderera isina kora kana kora, tambo yetrapezoidal yakabviswa ine kana isina kora, tambo yakatwasuka, kugadziriswa kwemagumo kwakakosha, kuvaka kwerin'i yechisimbiso.

Chiyero chesimbi chekuvhara peturu:

Chikamu chesimbi yemafuta chinogona kukamurwa kuita zvikamu zvesimbi zvakasiyana zvichienderana nesimba resimbi pachayo, zvinoti H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110, Q-125, nezvimwewo.Mamiriro etsime akasiyana, kudzika kwetsime, kushandiswa kwemhando yesimbi kwakasiyanawo. Chivharo pachacho chinodiwawo kuti chisapararire ngura munzvimbo dzine ngura. Munzvimbo dzine mamiriro akaomarara enzvimbo, chivharo chinodiwawo kuti chisapwanyike.

Fomura yekuverenga huremu hwechivharo chemafuta ndeiyi inotevera:

KG/ m = (dhayamita yekunze – ukobvu hwemadziro) * ukobvu hwemadziro *0.02466

Kureba kwechivharo chemafuta:

Kune mhando nhatu dzehurefu dzakatarwa neAPI: R-1 4.88 kusvika 7.62m, R-2 7.62 kusvika 10.36m, R-3 10.36m kusvika pakureba.

Rudzi rwebhandi remuchini wepeturu:

API 5CTMhando dzemabuckle epakeji yepetroleum dzinosanganisira STC (buckle pfupi yakatenderera), LTC (buckle refu yakatenderera), BTC (buckle yedanho rechikamu), VAM (buckle yamambo) nedzimwe mhando dzemabuckle.

Kuongororwa kwekushanda kwechikamu chepeturu:

(1) Zvinoenderana neSY/T6194-96. Kuita bvunzo yekutsanura (GB246-97) bvunzo yekukwesha (GB228-87) uye bvunzo ye hydrostatic.

(2) bvunzo ye hydrostatic, bvunzo yekupeta, bvunzo yekupwanya ngura ye sulfide stress, bvunzo yekuoma (ASTME18 kana E10 yazvino), bvunzo yekukwesha, bvunzo yekukanganisa inochinjika (ASTMA370, ASTME23 uye yazvino yemazinga akakodzera) zvichienderana nezvinodiwa neAmerican Petroleum Institute APISPEC5CT1988 first edition Ok), kusarudzwa kwehukuru hwezviyo (ASTME112 yazvino kana imwe nzira)

Kupinza nekutumira mafuta mubhokisi:

(1) Nyika huru dzinotakura mafuta dzinobva: Germany, Japan, Romania, Czech Republic, Italy, United Kingdom, Austria, Switzerland, United States, Argentina, Singapore inotumirawo mafuta.Mipimo yekupinza zvinhu inoreva mwero weAmerican Petroleum Institute API5A, 5AX, 5AC. Rudzi rwesimbi ndiH-40, J-55, N-80, P-110, C-75, C-95 nezvimwewo. Zvirevo zvikuru ndeizvi: 139.77.72R-2, 177.89.19R-2, 244.58.94R-2, 244.510.03R-2, 244.511.05r-2, nezvimwewo.

(2) Kune marudzi matatu ehurefu anotsanangurwa neAPI: R-1 i4.88 ~ 7.62m, R-2 i7.62 ~ 10.36m, R-3 i10.36m kusvika pakureba.

(3) Chikamu chezvinhu zvinopinzwa munyika chakanyorwa neLTC, kureva, chishongo chefilament buckle.

(4) Kuwedzera kune zvinodiwa zveAPI, huwandu hushoma hwemabushing anotengwa kubva kuJapan hunoenderana nezvinodiwa nevagadziri vekuJapan (vakadai seNippon Steel, Sumitomo, Kawasaki, nezvimwewo), nhamba dzesimbi ndiNC-55E, NC-80E, NC-L80, NC-80HE, nezvimwewo.

(5) Muzviitiko zvekukumbira, paive nezvikanganiso zvakaita semabhurukwa matema, kukuvara kwetambo yewaya, kupetwa kwemuviri wepombi, kucheka bhurukwa neshinda zvakapwanyika kure nekukwanisa kushivirira, kubatana kweJ kukosha nekukwanisa kushivirira, uye matambudziko emhando yepamusoro akadai sekutsemuka kwematombo uye simba shoma rebhokisi.
