I-IBOP, i-internal blowout preventer ye-top drive, ibizwa nangokuthi i-top drive cock. Emsebenzini wokumba uwoyela negesi, ukuqhuma kuyingozi abantu abangafuni ukuyibona kunoma iyiphi indawo yokumba. Ngoba kubeka engcupheni ukuphepha komuntu siqu kanye nempahla yezisebenzi zokumba futhi kuletha ukungcoliswa kwemvelo. Ngokuvamile, uketshezi olunomfutho ophezulu (uketshezi noma igesi), ikakhulukazi igesi enodaka namatshe, luzokhishwa esihlokweni somthombo ngesilinganiso sokugeleza esiphezulu kakhulu, senze indawo enyantisayo yokubhonga kweziqhumane. Umsuka wengozi uvela oketshezini oluphakathi kwezingqimba zamatshe angaphansi komhlaba, ezinomfutho ophakeme ngokungavamile. Lapho kubhobolwa lesi sikhawu, ukuguquguquka kwengcindezi kuzokwenzeka, futhi ukuqhuma kuzokwenzeka ezimeni ezimbi kakhulu. Ngokuthandwa kobuchwepheshe bokubhola obungalinganisiwe, amathuba okukhahlela nokuqhunyiswa makhulu kakhulu kunalawo okubhola okulingana okuvamile.
Kuhlanganiswe nezinye izinto zokusebenza kanye nobuchwepheshe ukuvala imbobo lapho ukukhahlela nokuqhunyiswa kuvela nje, ukuze abasebenzi bakwazi ukulawula ukukhahlela nokuqhunyiswa ngaphambi kokuthi kuqhume. Ngokuya ngokuma kweshaneli yokuvuthela, amathuluzi aku-rig yokumba angahlukaniswa abe isivimbeli sangaphakathi sokuvuthela, isivimbeli se-annular rotary blowout esihlokweni somthombo kanye nenqama.
Izinhlobo zama-BOP, njll. Lo mkhiqizo uwuhlobo lokuvimbela ukuqhuma kwentambo yokubhoboza, ebizwa nangokuthi i-top drive cock noma i-plug valve.I-top drive yangaphakathi yokuvimbela i-bloutout ekhiqizwa inkampani yethu ithatha izinto ezisezingeni eliphezulu ze-E-grade njengegobolondo, futhi ukwakheka kwayo kuqukethe umzimba we-valve, isihlalo se-valve esiphezulu, i-Wave spring, i-valve core, isibambo esihlukanisayo, isihlalo somkhono wesilayidi, i-valve ephansi yokubamba, i-valve ephansi indandatho,Indandatho yokusekela, indandatho egcina imbobo, i-O-ring seal, njll. Isivimbeli sokuqhuma kwangaphakathi ivalvu yebhola ene-metal seal, enesinxephezelo sentwasahlobo yamagagasi kanye nendlela yokuvala ingcindezi, enokusebenza okuthembekile kokuvala ngaphansi kwengcindezi ephezulu kanye nengcindezi ephansi. Igcina izinzuzo zesakhiwo sokuklama se-valve yebhola yoboya. Ukuze kuqashelwe ukuvala uphawu komfutho ophezulu, umshini wokuvala osizwa yingcindezi uyaklanywa, okwenza ukucindezela koketshezi oluvalekile kukhiqize amandla okuvala phakathi kwe-valve core kanye nezihlalo zamavalvu aphezulu naphansi, futhi la mandla okuvala adlala indima yokuvala okusizwa yingcindezi.
Ukuze kuzuzwe ukuvala uphawu lokucindezela okuphansi, kuklanywe indlela yokuqinisa ngaphambili kwentwasahlobo yamagagasi, ehlinzeka ngamandla adingekayo ukuze isihlalo sevalvu engezansi sicindezele ibhola. Okwesithathu, lapho i-valve core ivalwe ngezansi, isiphethu segagasi singanikeza amandla okuvala angathinteki umehluko wokucindezela komgogodla we-valve. Isigxivizo sokuqala esingenisiwe siyamukelwa, futhi siyafaneleka ukuphuma embonini ngemuva kokuhlolwa okune kokucindezelayo. Umthelela wokushintsha ungafinyelelwa nge-crank noma ngomkhawulo.Osayizi abahlukahlukene bangenziwa ngokwezifiso.
