Isithombe Esincane Esifakiwe Esijikelezayo Sebhola Eliningi Eliphonsa Amabhola

I-Sub Ejikelezayo Yamabhola Amaningi

Incazelo emfushane:

I-Multiple Drop Ball Circulating Sub iyithuluzi lokudonsa phansi elisebenza kahle kakhulu elenzelwe imisebenzi yokubhoboza eqondisa ngqo, evundlile, nene-engeli ephezulu. Ivumela ukuvulwa nokuvalwa okuphindaphindiwe kwama-bypass ports ukuthuthukisa ukusebenza kahle kokubhoboza, ukunciphisa izingozi zokulawula imithombo, kanye nokwenza imisebenzi ekhethekile njengokulawula ukujikeleza kwegazi okulahlekile kanye nokuhlanza imisele yamanzi—ngaphandle kokukhubeka.

Incazelo Yomkhiqizo

I-Multiple Drop Ball Circulating Sub iyisethi yokuxhumana okufushane okungavulwa futhi kuvalwe izikhathi eziningi. Ngokuvamile ifakwa ku-BHA ekhethekile njengokuqondisa, ukusheshisa, ukugawula ngenkathi kubholwa nokunye. Ingavula futhi ivale imbobo ye-bypass ngesikhathi sokusebenza okukhethekile ngokwezidingo zezimo ze-downhole, ukuze kuthuthukiswe ukusebenza kwe-BHA ekhethekile, kuthuthukiswe ukusebenza kahle kokukhiqiza futhi kuncishiswe ingozi yokulawula umthombo.

Izingxenye Eziyinhloko

I-Bypass Sub– Izindlu ezinezimbobo ezishelelayo kanye nezimbobo.
I-Ball Catcher Sub– Iqoqa amabhola awile ngemuva kokusebenzisa.
Iqembu Lebhola Lokushintsha- Kufaka phakathi ukwenza kusebenze, ukuvala, kanye nokukhiya amabhola.

Ukwakhiwa Komkhiqizo

I-Multiple Drop Ball Circulating Sub valve yakhiwe kakhulu yi-bypass sub, i-ball catcher sub kanye ne-switch ball group. Njengoba kuboniswe kuMfanekiso 1. Iqoqo le-switch ball group lihlanganisa: ibhola lokuqalisa, amabhola amabili okuvala kanye nebhola lokukhiya. Ibhola lokuqalisa kanye nebhola lokukhiya kwenziwa ngohlobo olusha lwepulasitiki yobunjiniyela, kanti ibhola lokuvala lenziwe ngensimbi ejwayelekile yokuthwala.

Imisebenzi Eyinhloko

Ukulawulwa Kokujikeleza Kwegazi Okulahlekile

Pompa izinto zokuxhuma ezigxilile kakhulu (isb., usimende) ngqo ezindaweni zokulahlekelwa ngamachweba adlulayo.

Ukuwasha Imithombo Ehlala Abantu Abaningi

Imibhede yokusika ehlanziwe emithonjeni eqondile/evundlile.
Hlanza i-casing kanye ne-BOP stack.

Ukupompa Uketshezi Olugqwalisayo

Phatha ngokuphephile ama-asidi noma ezinye izinto eziwuketshezi ezivuthayo.

Ukugaywa Nokulungiswa Kwamafasitela

Susa ama-metal burrs ngesikhathi sokuphambukisa izintambo.

Isiteshi Sokujikeleza Okubuyela Emuva

Khiya imbobo eyodwa yokudlula ukuze ujikeleze emuva ngesikhathi sohambo.
