Zvishandiso zvekugadzira mafuta:

Inoshandiswa pakuchera matsime emafuta inonyanya kushandiswa mukuchera uye mushure mekupedzwa kwechitsigiro chemadziro emadziro, kuitira kuti kuve nechokwadi chekuchera uye kushandiswa kwemaitiro emvura yose mushure mekupedzwa.Nekuda kwemamiriro akasiyana e geological, pasi pevhu. Stress state yakaoma, uye kuita kwakazara kwekusimba, kudzvanya, kukotama uye torsional kushushikana pamutumbi wepombi inoisa mberi zvinodiwa zvepamusoro zvemhando yecasing pachayo. yakakuvadzwa nekuda kwechimwe chikonzero, inogona kutungamirira mukuderedzwa kwekugadzirwa kwetsime rose, kana kunyange zvimedu.

Mhando dzemafuta emafuta:

Zvinoenderana neSY/T6194-96 "petroleum casing", inogona kupatsanurwa mumhando mbiri: pfupi yakasungwa casing uye collar yayo uye refu yakarukwa casing nekora yayo.

Oiri casing standard uye kurongedza:

Maererano neSY/T6194-96, chivharo chemumba chinofanira kusungwa netambo yesimbi kana bhandi resimbi. Chikamu chakafumurwa chega rega rega uye collar thread inofanira kuvharwa nemhete yekudzivirira kuchengetedza tambo.

Iyo casing ichapihwa neshinda uye collar zvinoenderana neAPI SPEC 5CT1988 yekutanga edition kana mune chero anotevera pombi ekupedzisira mafomu: flat kupera, denderedzwa tambo isina collar kana collar, offset trapezoidal tambo ine kana isina collar, yakatwasuka tambo, yakakosha kupera kugadzirisa. , kugadzirwa kwemhete yechisimbiso.

Simbi giredhi ye petroleum casing:

Oiri casing simbi giredhi inogona kukamurwa kuita akasiyana simbi mamakisi zvichienderana nesimba resimbi pachayo, kureva H-40, J-55, K-55, N-80, C-75, L-80, C-90, C. -95, P-110, Q-125, nezvimwewo.Mamiriro akasiyana-siyana ezvakanaka, kudzika kwakadzika, kushandiswa kwesimbi yegiredhi zvakare kwakasiyana.Iyo casing pachayo inodawo kuti ive ne-corrosion-resistant munzvimbo dzinopisa.Munzvimbo dzine mamiriro ezvinhu akaoma e geological, casing inodawo kuti irege kuparara.

Iyo huremu yekuverenga fomula yemafuta casing ndeiyi inotevera:

KG/ m = (kunze dhayamita - madziro ukobvu) * madziro ukobvu * 0.02466

Urefu hwebhokisi remafuta:

Kune marudzi matatu ehurefu hunotsanangurwa neAPI: R-1 4.88 kusvika 7.62m, R-2 7.62 kusvika 10.36m, R-3 10.36m kusvika kureba.

Petroleum casing buckle mhando:

API 5CTpetroleum casing buckle marudzi anosanganisira STC (short round buckle), LTC (long round buckle), BTC (partial ladder buckle), VAM (king buckle) nedzimwe mhando dzemabuckle.

Kuongororwa kwekuita kwemuviri kwepetroleum casing:

(1) Maererano neSY/T6194-96.Kuita flattening test (GB246-97) tensile test (GB228-87) uye hydrostatic test.

(2) hydrostatic bvunzo, flattening test, sulfide stress corrosion cracking test, hardness bvunzo (ASTME18 kana E10 yazvino vhezheni), tensile bvunzo, transverse kukanganisa bvunzo (ASTMA370, ASTME23 uye yazvino vhezheni yezviyero zvinoenderana) zvinoenderana nezvinopihwa American Petroleum Institute APISPEC5CT1988 yekutanga edition Ok), kutsunga kwehukuru hwezviyo (ASTME112 yazvino vhezheni kana imwe nzira)

Oiri casing kupinza uye kutumira kunze kwenyika:

(1) Nyika dzinonyanya kupinza mafuta casing ndeidzi: Germany, Japan, Romania, Czech Republic, Italy, United Kingdom, Austria, Switzerland, United States, Argentina, Singapore zvakare.Kupinza mitemo kunoreva American Petroleum Institute standard API5A, 5AX, 5AC.Steel giredhi H-40, J-55, N-80, P-110, C-75, C-95 zvichingodaro.Mashoko makuru ndee139.77. 72R-2, 177.89.19R-2, 244.58.94R-2, 244.510.03R-2, 244.511.05r-2, nezvimwewo.

(2) Kune marudzi matatu ehurefu hunotsanangurwa neAPI: R-1 is 4.88 ~ 7.62m, R-2 ndeye 7.62 ~ 10.36m, R-3 ndeye 10.36m kusvika kureba.

(3) Chikamu chezvinhu zvinotengeswa kunze kwenyika zvakamisikidzwa neLTC, kureva, filament buckle sleeve.

(4) Pamusoro pezviyero zveAPI, nhamba shoma yebhushi inotengeswa kubva kuJapan inoteedzera zviyero zvevagadziri veJapan (seNippon Steel, Sumitomo, Kawasaki, nezvimwewo), nhamba dzesimbi NC-55E, NC-80E, NC. -L80, NC-80HE, nezvimwewo.

(5) Mumatare edzimhosva, paive nekuremara senge black buckle, wire tie kukuvadzwa, kupeta muviri wepombi, bhureki rakatyoka uye tambo yakasimba kureba kunze kwekushivirira, kubatanidza J kukosha kunze kwekushivirira, uye matambudziko emukati emhando senge brittle cracking. uye kuderera kwegoho simba rebhokisi.
