Dzidza Zvakawanda Nezve Oiri Casing: Mashandisirwo, Misiyano Kubva kuAPI mapaipi, uye Zvimiro

Muhurongwa hukuru hweindasitiri yeoiri, kusungirirwa kweoiri kunoita basa rakakosha. Zviri aSimbi Piperaishandiswa kutsigira madziro etsime remafuta negasi matsime. Ndiyo kiyi yekuve nechokwadi chekuchera kwakatsetseka uye kushanda kwakajairwa kwemafuta mutsime mushure mekupedza. Tsime rega rega rinoda akawanda akaturikidzana ecasing nekuda kwekudzika kwakasiyana kwekuchera uye geological mamiriro. Mushure mekunge casing yadzikiswa mutsime, simende inodiwa. Kusiyana nepombi dzemafuta nemapombi ekuchera, inguva imwe chete inodyiwa, uye kushandiswa kwayo kunodarika 70% yepombi dzese dzetsime remafuta. Zvinoenderana nekushandiswa, mafuta casing anogona kupatsanurwa kuita mapaipi ekutungamira, pamusoro casings, tekinoroji casings, uye mafuta layer casings.

Vanhu vazhinji vanowanzo vhiringa bhokisi remafuta neAPI Pipe, asi pane kusiyana kuri pachena pakati pezviviri izvi. API pombi imhando yepombi pasi pemashandisirwo ekushanda akaunganidzwa uye akaburitswa neAmerican Petroleum Institute, inofukidza huwandu hwakasiyana, kusanganisira dzakasiyana siyana dzepombi zvigadzirwa zvinoshandiswa muindasitiri yemafuta. Oiri casing ipombi yakakura-dhayamita pombi inonyanyo shandiswa kugadzirisa madziro kana tsime remafuta negasi matsime. Zvichitaurwa zviri nyore, API pombi chiyero, uye mafuta casing ipombi inogadzirwa zvichienderana nechiyero ichi uye ine chinangwa chaicho.

Oiri casing ine akawanda akakosha maitiro. Kubva pakuona kwesimba, inogona kugoverwa muzvikamu zvakasiyana-siyana zvesimbi maererano nesimba resimbi pachayo, sseJ55, K55, N80, L80, C90, T95, P110, Q125, V150, nezvimwe., kujairana nemamiriro akasiyana etsime uye kudzika kwetsime. Munzvimbo dzine mamiriro akaoma e geological, iyo casing inodikanwa kuti ive yakanaka anti-kudonha kuita, kugona kutsungirira kudzvanywa kweakatenderedza matombo maumbirwo, uye kudzivirira casing kubva deformation uye kukuvara. Munzvimbo ine njodzi dzekuora, iyo casing inofanirwa kuve nekushomeka kwekudzivirira kudzivirira kutetepa kwepombi madziro uye kuderedzwa kwesimba nekuda kwekuora, izvo zvinozokanganisa kushanda kwakajairika uye hupenyu hwebasa retsime remafuta.

Oiri casing inotora chinzvimbo chisingadzoreki mukugadzirwa kweoiri. Kushandiswa kwayo kwakasiyana, mutsauko kubva kuAPI mapaipi, uye hunhu hwayo zvese zvakakosha zvinhu kuti ive nechokwadi chekushanda kwakanaka uye kwakachengeteka kweindasitiri yemafuta.
