Ukuhlukaniswa kanye nokusebenzisa ukufakwa kowoyela

Ngokusho komsebenzi, ukufakwa kowoyela kuhlukaniswe: ukubekwa komhlaba, ukuhlanganisa ubuchwepheshe kanye nokubekwa uwoyela we-oyili.

1. I-Case

1. Isetshenziselwa ukuhlukanisa okuthambile, okulula ukuwa, kulula ukuwaza ekwakhiweni nasezandleni zamanzi ezingalungiswa kakhulu engxenyeni engenhla;

2. Faka ukufakwa kwe-Wellhead ukulawula i-blowout;

Ukujula kobuso obungaphandle kuncike esimweni esithile, imvamisa amashumi amamitha amamitha kuya kumakhulu amamitha noma ajulile (30- 1000m). Ukuphakama kwesimende ukuphakama ngaphandle kwepayipi kuvame ukubuyela emoyeni. Lapho ushayela igesi ephezulu yokucindezela, uma ukwakheka kwedwala phezulu kukhululeke futhi kuphulwe, ukuze kuvinjelwe ukuhamba komoya okuphezulu kakhulu ngenxa yokuphunyuka emoyeni, ukucaca komhlaba kudinga ukwehliswa kahle. Uma ukubonwa kobuso kudinga ukujula, lapho isikhathi sokuqala sokumba side, kufanele ucabangele ukwehlisa ungqimba lwe-conduit ngaphambi kokuhliswa kokwakheka komhlaba. Umsebenzi wayo ukuhlukanisa ingaphezulu, uvikele i-Wellhead kusuka ekuweni, bese wakhe isiteshi sokujikeleza soketshezi sokumba ngokumba isikhathi eside. Ukujula kwe-casing ngokuvamile kuvame amamitha angama-20- 30, futhi usimende ongaphandle kwepayipi ubuyela emoyeni. I-Casing ngokuvamile yenziwe ngepayipi elivuthayo noma ipayipi eliqondile

2.

1. Isetshenziselwa ukwahlukanisa okunzima ukulawula nge-dring fluid, izingqimba ezivuvukala ezibucayi, kanye no-oyela, igesi, namapheya wamanzi ngomehluko omkhulu wokucindezela, ukuze uvikele ukwanda komthombo;

2. Emithonjeni eqondayo ngokuthambekela okukhulu, ukufakwa kwezobuchwepheshe kwehliswe esigabeni sokuthambekela ukwenza lula ukumba okuphephile komthombo oqondayo kahle.

I-3. Inikeza izimo zokufakwa, ukuvinjelwa kwe-blowaut, ukuvimbela ukuvuza kanye nokumiswa kwamapayipi omsila wemishini yokulawula kahle, futhi futhi kunomphumela wokuvikela e-oyili ungqimba.

I-Consage technical akudingeki yehliswe. Izimo eziyinkimbinkimbi eziphansi komthombo zingalawulwa ngokwamukela uketshezi olusezingeni eliphezulu, ukusheshisa isivinini sokumba, ukuqinisa ukumba nezinye izindlela, futhi kulwele ukwehlisa noma ukwehlisa ukona kwezobuchwepheshe. Ukujula okwehlisiwe kwezobuchwepheshe kuncike ekwakhekeni okuyinkimbinkimbi ukuze kuhlukaniswe. Ukuphakama kwesimende ukubuyela kwesimende kufanele kufinyelele kumamitha angaphezu kwe-100 wokwakheka okuzodwa. Ngemithombo yegesi ephezulu, ukuze uvikele kangcono ukuvuza, usimende uvame ukubuyiselwa emoyeni.

3. I-OIL Ungqimba

Kusetshenziselwa ukuhlukanisa ungqimba oluqondiwe kusuka kwezinye izingqimba; Ukuhlukanisa izingqimba zamafutha, igesi kanye nezingcindezi ezahlukahlukene, ukusungula isiteshi samafutha nephethiloli emthonjeni ukuqinisekisa ukukhiqizwa kwesikhathi eside. Ukujula kwe-oyili ungqimba crosing kunqunywa ngokujula kwesendlalelo esiqondiwe kanye nendlela yokuqeda. I-slurry kasimende ye-oyili ungqimba Crosing ngokuvamile ibuyiselwa kumafutha aphezulu nangaphezulu wegesi ngaphezulu kwamamitha ayi-100. Kwimithombo yengcindezi ephezulu, i-slurry kasimende kufanele ibuyiselwe emhlabathini, okulungele ukuqinisa ukonakala kanye nokwenza ngcono ukubekwa uphawu kwentambo ecashile kawoyela, ukuze ikwazi ukubekezelela ingcindezi enkulu yokuvalwa.
