Ukuqonda Umsebenzi Wezihlukanisi Zegesi Yodaka Ekumbiweni Kwamafutha Negesi
Emisebenzini yokumba uwoyela negesi, ukuphepha nokusebenza kahle kubaluleke kakhulu. Isisetshenziswa esibalulekile esidlala indima ebalulekile ekuqinisekiseni ukuphepha nokusebenza kahle yi-Isihlukanisi Segesi Yodaka (MGS). Kodwa sisebenza kanjani isihlukanisi segesi yodaka, futhi kungani sibalulekile emisebenzini yokumba?
Ukuze uqonde umsebenzi we-aisihlukanisi segesi yodaka, kufanele uqale ubambe umqondo wokumba igesi. Ekubholeni igesi, uketshezi lokumba, olubizwa nangokuthi udaka, lusetshenziselwa ukugcobai-drill bit, thwala ama-cuttings phezulu futhi ugcine ingcindezi ye-wellbore. Kodwa-ke, ngesikhathi sokumba, igesi yemvelo kanye namanye ama-hydrocarbon nawo angakhululwa ekubunjweni futhi ahlanganiswe noketshezi lokumba. Lokhu kungaholela ekwakhekeni kokungena kwegesi okuthi, uma kungalawulwa, kuholele ekuqhumeni okuyingozi nokungaba yinhlekelele.
Lapha kulaphoisihlukanisi segesi yodakakungene ukudlala. Umsebenzi oyinhloko wesihlukanisi segesi yodaka ukuhlukanisa nokukhipha uketshezi lokumba oketshezini lokumba ngaphambi kokuba lufinyelele phezulu. I-MGS ifinyelela lokhu ngokuhlanganiswa kwamandla adonsela phansi kanye nezinqubo zokuhlukaniswa kwemishini.
Izihlukanisi zegesi yodakangokuvamile imikhumbi emi evumela ukuthi uketshezi olumbayo negesi kungene ukusuka phezulu. Njengoba ingxube ingena esitsheni, amandla adonsela phansi abangela ukuba uketshezi olusindayo lokumba luhlale phansi kuyilapho amagesi alula akhuphukela phezulu. Isiqukathi sifakwe ama-baffles angaphakathi kanye nedivayisi yokususa inkungu ukusiza ukuthuthukisa inqubo yokuhlukanisa. Khona-ke igesi ehlukanisiwe ifakwa endaweni ephephile kude nendawo yokumba, kuyilapho uketshezi lokumba luqhubeka nokubuyela ohlelweni lodaka.
Enye yezingxenye ezibalulekile zesihlukanisi segesi yodaka ulayini wokukhipha umoya, oklanyelwe ukuthwala igesi ehlukanisiwe ngokuphepha kude ne-rig. Lokhu kubalulekile ukuze kuvinjwe ukunqwabelana kwegesi eduze kwe-rig, ukunciphisa ingozi yomlilo noma ukuqhuma.
Ngaphandle komsebenzi wayo oyinhloko wokuhlukaniswa kwegesi, isihlukanisi segesi yodaka sisebenza njengethuluzi lokuphepha. Esimeni sokukhahlela, ukuthutheleka koketshezi okwakheka kumthombo, i-MGS inganikeza indlela yokuphambukisa igesi kude nerigi, ngaleyo ndlela yehlise ingcuphe yokuqhunyiswa. Lokhu kufezwa ngokuhlukanisa ngokushesha nangempumelelo igesi kuketshezi lokumba, okusiza ukugcina ukulawula kahle nokuvimbela izingozi ezingaba khona.
Kafushane, izihlukanisi zegesi yodaka ziyizingxenye ezibalulekile emisebenzini yokumba uwoyela negesi. Ikhono layo lokuhlukanisa kahle igesi kuketshezi lokumba, kuhambisana nokuphepha kwayo okuthuthukisiwe ngokuphambukisa igesi kude ne-rig, kuyenza ibe ucezu lwesisetshenziswa esibalulekile. Ukuqonda ukuthi izihlukanisi zegesi yodaka zisebenza kanjani kubalulekile ekuqinisekiseni ukuphepha nempumelelo yokusebenza kokumba embonini kawoyela negesi.
