Incazelo ye-Oil Casing Connections

Emisebenzini yokumba uwoyela, uhlobo lokuxhuma lwamathuluzi okumba luyingxenye ebalulekile futhi eyinkimbinkimbi. Uhlobo lokuxhuma aluthinti kuphela ukusetshenziswa kwamathuluzi kodwa lubalulekile nasekuphepheni nasekusebenzeni kahle kokumba imisebenzi. Ukuqonda izinhlobo ezahlukene zokuxhuma kusiza abasebenzi ukuthi benze izinqumo ezifanele mayelana nokukhetha impahla, ukulungiswa, kanye neziqondiso zokusebenza. Lesi sihloko sinikeza incazelo enemininingwane yokuxhunywa kwamapayipi kawoyela avamile, okuhlanganisa i-EU, i-NU, ne-VAM Entsha, futhi yethula kafushane ukuxhunywa kwamapayipi okumba.

Ukuxhumana Kwepayipi Kawoyela Okuvamile

1. Uxhumo lwe-EU (Ukucasuka Kwangaphandle).
   • Izici: Uxhumano lwe-EU wuhlobo oluphazamisekile lwangaphandle lwejoyinti likawoyela elivame ukufaka ungqimba olwengeziwe logqinsi ngaphandle kwelunga ukuze kuthuthukiswe amandla alo nokuqina.
   • Izimpawu: Ku-workshop, amamaki ahlukene okuxhumana kwe-EU afaka:
     • I-EUE (Ukuphela Okucasulayo Kwangaphandle): Ukuphela kokucasuka kwangaphandle.
     • I-EUP (Iphinikhodi yangaphandle): Uxhumo lwangaphandle olucasule amadoda.
     • I-EUB (Ibhokisi Elicasulayo Langaphandle): Uxhumano lwangaphandle oluphatheke kabi kwabesifazane.
   • Umehluko: Ukuxhumana kwe-EU ne-NU kungase kubonakale kufana, kodwa kungahlukaniswa kalula ngezici zakhona zizonke. I-EU ikhombisa ukucasuka kwangaphandle, kuyilapho i-NU ayinaso lesi sici. Ukwengeza, i-EU ngokuvamile inemicu engu-8 iyintshi ngayinye, kuyilapho i-NU inemicu eyi-10 iyintshi ngayinye.
2. Uxhumo lwe-NU (Olungaphatheki kabi).
   • Izici: Uxhumano lwe-NU alunawo umklamo wangaphandle wokucasula. Umehluko omkhulu ovela e-EU ukungabikho kogqinsi olwengeziwe lwangaphandle.
   • Izimpawu: Ngokuvamile zimakwa njenge-NUE (Ukuphela Okungajabulisi), okubonisa isiphetho ngaphandle kokucasuka kwangaphandle.
   • Umehluko: I-NU ngokuvamile inemicu engu-10 iyintshi ngayinye, okuwukuminyana okuphezulu uma kuqhathaniswa nemicu engu-8 iyintshi ngayinye ekuxhumekeni kwe-EU.
3. Uxhumano Olusha lwe-VAM
   • Izici: Uxhumo olusha lwe-VAM lufaka umumo ophambanayo owunxande, onesikhala esilinganayo somucu kanye ne-taper encane. Ayinayo idizayini ecasulayo yangaphandle, eyenza ihluke ekuxhumekeni kwe-EU ne-NU.
   • Ukubukeka: Izintambo ezintsha ze-VAM ziyi-trapezoidal, okwenza kube lula ukuhlukanisa kwezinye izinhlobo zokuxhuma.

Ukuxhumana Okujwayelekile Kwepayipi Lokubhoboza

1. REG (Okuvamile) Ukuxhumana
   • Izici: Uxhumo lwe-REG luhambisana namazinga e-API futhi lusetshenziselwa uxhumo olujwayelekile lwentambo yamapayipi okubhola. Lolu hlobo lokuxhuma lwalusetshenziselwa ukuxhuma amapayipi okubhoboza aphazamisekile ngaphakathi, ukuqinisekisa amandla nokuzinza kwamapayipi amapayipi.
   • Ukuminyana Komucu: Uxhumo lwe-REG ngokuvamile luba nemicu emi-5 iyintshi ngayinye futhi lusetshenziselwa amadayamitha amapayipi amakhulu (okungaphezu kuka-4-1/2”).
2. IF (I-Internal Flush) Uxhumo
   • Izici: Ukuxhuma kwe-IF nakho kuhambisana nezindinganiso ze-API futhi ngokuvamile kusetshenziselwa ukubhoboza amapayipi anobubanzi obungaphansi kuka-4-1/2”. Idizayini yochungechunge i-coarer uma iqhathaniswa ne-REG, futhi ukuthungwa kugqama kakhulu.
   • Ukuminyana Komucu: UMA ukuxhumana ngokuvamile kunemicu emi-4 iyintshi ngayinye futhi kuvame kakhulu kumapayipi amancane kuno-4-1/2”.

Isifinyezo

Ukuqonda nokuhlukanisa izinhlobo ezahlukene zokuxhuma kubalulekile ekusebenzeni kahle kwemisebenzi yokumba. Uhlobo ngalunye lokuxhuma, olufana ne-EU, NU, kanye ne-VAM Entsha, lunezici ezithile zokuklama nezimo zohlelo lokusebenza. Emapayipini okubhoboza, ukukhetha phakathi kokuxhumeka kwe-REG ne-IF kuncike kububanzi bepayipi kanye nezidingo zokusebenza. Ukujwayelana nalezi zinhlobo zokuxhuma kanye nezimpawu zazo kusiza abasebenzi ukuthi benze izinqumo ezinolwazi, baqinisekise ukusebenza kahle nokuphepha kwemisebenzi yokumba.
