I-BOP isetshenziselwa ukuvala umthombo ngesikhathi sokuhlolwa kukawoyela, ukulungiswa komthombo, kanye nemisebenzi yokuqeda kahle ukuze kunqandwe izingozi zokuqhunyiswa kwamanzi. Ihlanganisa ukuvala okugcwele kanye nemisebenzi yokuvalwa kwe-semi-seal ibe yinto eyodwa, futhi inezici zesakhiwo esilula, ukusebenza okulula, nokumelana nokucindezela okuphezulu. Ivamise ukusetshenziswa ukuphepha kokuvala izinsiza ze-wellhead ezindaweni zikawoyela ukuze kunqandwe ukuphuma. Kunezinhlobo ezimbili eziyinhloko ze-BOP evamile:I-BOP yonyakafuthiinqama BOP. Uma usebenzisa i-BOP esizeni, izinhlobo ezahlukene zama-BOP zivame ukuhlanganiswa ngokwezidingo. Ngokuvamile, ingxenye engaphezulu iyi-BOP yonyaka, ingxenye ephakathi igcwele inqama engu-BOP kanye nenqama yokugunda i-BOP, ingxenye engezansi i-BOP yenqama enguhhafu, njll. Kunezinhlanganisela ezihlukene ngokwemibandela yendawo.
Ukukhethwa kwe-BOP Assembly
Izici okufanele zicatshangelwe ekukhetheni inhlanganisela ye-hydraulic BOP yilezi: uhlobo lomthombo, ukucindezela kokubunjwa, usayizi we-casing, uhlobo loketshezi lokubunjwa, isimo sobuchwepheshe sabasebenzi, izidingo zezinqubo zobuchwepheshe, umthelela wesimo sezulu, izimo zethrafikhi, izimo zokuhlinzekwa kwempahla, kanye nezidingo zokuvikelwa kwemvelo. Ngamafuphi, kufanele ikwazi ukufeza ingcindezi yokumba elinganiselayo, iqinisekise ukuphepha kokumba, futhi yonge izindleko zokumba.
1)Ukukhethwa Kwezinga Lokucindezela
Ukucindezela kokusebenza komhlangano we-hydraulic BOP kuncike ekuphikiseni kwengcindezi yangaphakathi kwe-casing, ingcindezi yokuphuka kokwakheka kwembobo evulekile esicathulweni se-casing kanye nokucindezela okuphezulu okulindelekile kwe-wellhead. Kodwa ikakhulukazi kunqunywa ukucindezela okuphezulu kwe-wellhead okulindeleke ukuthi umhlangano we-BOP umelane nawo. Kunamazinga wokucindezela we-BOP amahlanu:14MPa, 21MPa,35MPa,70MPa,105MPa, kanye140I-MPa.
2)Ukukhetha Ububanzi
Ububanzi bomhlangano we-BOP buncike kusayizi we-casing ekwakhiweni kwesakhiwo se-wellbore, okungukuthi, kufanele kube kukhudlwana kunobubanzi obungaphandle be-casing exhunyiwe. Kunezinhlobo eziyisishiyagalolunye zamadayamitha we-BOP:180mm,230mm,280mm,346mm,426mm,476mm,528mm,540mm, futhi680mm. Phakathi kwazo,230mm,280mm,346mm, futhi540mm zivame ukusetshenziswa esizeni.
3)Ukukhethwa kwe-BOP Assembly
Ukukhethwa kwefomu lokuhlanganiswa kusekelwe ikakhulukazi ekucindezelweni kokubunjwa, izidingo zenqubo yokumba, isakhiwo samathuluzi okumba kanye nezimo zokufanisa imishini.
I-BOP iyithuluzi elibaluleke kakhulu lokuqinisekisa ukuphepha kokulawula kahle. Njengoba ukuhlola nokuthuthukiswa kwensiza kawoyela negesi okujulile nokujule kakhulu sekuphenduke inkundla yempi yokugcina uwoyela negesi nokukhiqizwa eminyakeni yamuva nje, ukuklanywa kanye nokukhiqizwa kwezinqamuleli zokuvuthela nakho sekuthuthukele ekucindezelweni okuphezulu kanye nobubanzi obukhudlwana. I-PWCE ibilokhu ibambelele emibonweni ewumongo yokuqina, ubuhlakani kanye nokwethembeka, futhi izibophezele ekukhiqizeni izinqamuleli zokuqhunyiswa kwekhwalithi ephezulu. Sicela usithinte ukuze uthole imininingwane eyengeziwe mayelana nemikhiqizo yokuvimbela i-bloout.
Uma unemibuzo noma udinga ulwazi olwengeziwe, sicela ukhululeke ukuxhumana nethimba lethu labadayisi.
