casing repair

Pakati nepakati uye yekupedzisira nhanho yekushandiswa kweoiri, nekuwedzera kwenguva yekugadzira, huwandu hwekushanda uye workovers hunowedzera, uye kukuvara kwecasing kuchaitika zvakateerana. Mushure mekunge casing yakuvadzwa, inofanirwa kugadziriswa nenguva, zvikasadaro zvinozokonzera tsaona dzemugomba.

1. Kuongorora uye kuyerwa kwekukuvadzwa kwekasi

Izvo zvakakosha zviri mukati mekuongorora kwekasi ndezvi: shanduko yemukati dhayamita yekasi, kunaka uye kukora kwemadziro evhavha, mamiriro emukati madziro evhavha, nezvimwe. Uyezve, tarisa uye uone nzvimbo ye casing collar, nezvimwewo.

2. Kugadziriswa kweganda rakaremara

Iyo yakaremara casing inogadziriswa nekuvhiyiwa kwepurasitiki.

⑴Pear-shaped plastic device (inonziwo chubhu expander)

Iyo tube expander inodzikiswa kune yakaremara tsime chikamu, uye chikamu chakaremara chinowedzerwa zvishoma nezvishoma zvichienderana nebulging simba rechidhiro. Iyo lateral kureba iyo inogona kuwedzerwa nguva imwe neimwe inongova 1-2 mm, uye nhamba yezvishandiso zvinotsiva yakakura.

⑵ Casing shaper

Ichi chishandiso chinoshandiswa zvakanyanya uye chiri nani chekugadzira.

Iyo casing shaper chishandiso chakakosha chinoshandiswa kugadzirisa deformation yecasing mutsime, senge flattening uye kuora mwoyo, kuitira kuti idzorere kumamiriro ari padyo neyakajairwa.

Iyo casing shaper ine eccentric shaft, pane iyo yepamusoro, yepakati uye yakaderera rollers uye musoro wekoni, pamwe nemabhora nemapulagi ekugadzirisa musoro wekoni. Isa chishandiso ichi pane chakaremara chikamu checasing, chitenderedza uye shandisa kudzvanywa kwakakodzera, uchimanikidza musoro wekoni uye roller kusvina akaremara pombi madziro e casing kunze nehombe lateral simba kuti isvike kune yakajairika dhayamita uye kutenderera.

Casing scraper: Iyo casing scraper inoshandiswa kubvisa chero madhipoziti, kusaenzana kana burrs mukati memafuta egodhi casing, kuitira kuti abvise zvipingamupinyi zvekushanda mune ramangwana.

3. casing subsidy

Matsime ane mabhonzo kana akatsemuka casings anogona kugadzirwa nerubatsiro. Iyo dhayamita yemukati yekasi yakagadziriswa inofanira kuderedzwa neanenge 10mm, uye rubatsiro runogona kuva 10 ~ 70m mune imwe kuvaka.

⑴ rubatsiro rwekutarisira

Ukobvu hwepombi yerubatsiro kazhinji ipombi yesimbi isina musono ine mudhuri wemudhuri we3mm, iine mahombe erengitudinal ripples, uye jira regirazi gobvu 0.12mm rakaputirwa papombi, rakasimbiswa ne epoxy resin, uye pombi yega yega yakareba 3m. Paunenge uchishandiswa, kureba kwepombi yepasi kunogona kusungirirwa panzvimbo maererano nezvinodiwa zvekugadzira, uye rusvingo rwekunze rwakaputirwa ne epoxy resin isati yapinda mutsime.

(2) Zvishandiso zvekubatsira

Iyo inonyanya kuumbwa necentralizer, inotsvedza sleeve, yekumusoro inorova, hydraulic anchor, piston barrel, yakagadziriswa piston, piston, kumusoro musoro, piston tsvimbo, inotambanudza chubhu uye chubhu inowedzera.

4. Casing mukati chibooreso

Kuchera mukati me casing kunonyanya kushandiswa kugadzirisa matsime emafuta nekutadza kwakakomba downhole. Zvakaoma kuti zvive zvinobudirira mukubata nematsime akaoma akadaro nenzira dzakawanda. Casing sidetracking tekinoroji inofanirwa kushandiswa kudzoreredza matsime akafa uye kugadzirisa mashandisirwo emafuta mutsime.

Kudhiraivha mukati mecasing kugadzirisa mudziyo wekutsaudzira pane imwe kudzika kwemafuta-mvura mutsime, shandisa iyo yakarerekera ndege kuvaka uye kutungamira kutsauka, uye shandisa iyo milling cone kuvhura hwindo padivi pekasi, drill. gomba idzva nepahwindo, uye wozodzikisa liner kuti ugadzirise. Seti yakanaka yehunyanzvi. Iyo casing mukati mekuchera tekinoroji iko kushandiswa kweinotungamira yekuchera tekinoroji mukugadziridza kwemafuta uye matsime emvura.

Zvishandiso zvikuru zvekuchera mukati mecasing zvinosanganisira inclination setter, inclination feeder, milling cone, drill bit, drop joint, simende yerabha plug, nezvimwe.
