Iqhaza lemishini yesihlahla sikaKhisimusi ekubholeni ama-wellheads

Njengoba kusondela isikhathi samaholidi, abantu abaningi bamatasatasa behlobisa izihlahla zabo zikaKhisimusi futhi bathola umoya wamaholide. Kodwa bewazi yini ukuthi igama elithi "isihlahla sikaKhisimusi" libuye lisetshenziswe embonini kawoyela negesi kubhekiselwa ezintweni ezibalulekile ezisetshenziswa embonini kawoyela negesi.ukumba amakhanda? Kule bhulogi, sizohlola indima yeImishini yesihlahla sikaKhisimusiendaweni yokubhola nokuthi iqinisekisa kanjani ukukhishwa okuphephile nokusebenza kahle kukawoyela negesi.

Isihlahla sikaKhisimusi, esibizwa nangokuthi aikhanda elihle, wumhlangano weama-valve, ama-spools, nezinsimbi ezifakwe phezulu komthombo ukuze kulawulwe ukuhamba kukawoyela negesi yemvelo emthonjeni. Iyingxenye ebalulekile yemishini ye-wellhead futhi idlala indima ebalulekile ekukhiqizeni nasekugcinweni kwemithombo kawoyela.

Omunye wemisebenzi eyinhloko yesihlahla sikaKhisimusi ukulawula ukugeleza koketshezi emthonjeni. Lokhu kufezwa ngochungechunge lwamavalvu angavulwa noma avalwe ukuze kulawuleke ukugeleza kukawoyela, igesi yemvelo, nolunye uketshezi oluphuma emthonjeni. Isihlahla sikaKhisimusi siphinde sihlinzeke ngokufinyelela emthonjeni ukuze kulungiswe futhi kungenelele imisebenzi, sivumela abaqhubi ukuthi benze imisebenzi efana nokuhlola umthombo, ukusebenza kwezingcingo kanye nokuqhekeka kwe-hydraulic.

Izihlahla zikaKhisimusi ngokuvamile zifakwe ama-valve ahlukahlukene, kuhlanganiseama-valve amakhulu,ama-valve aphikofuthiama-throttle valves, ukulawula ukugeleza koketshezi nokuvala umthombo ezimeni eziphuthumayo. Lawa ma-valve asetshenziswa ukude ukusuka phezulu kusetshenziswa isistimu yokulawula, okuvumela opharetha ukuthi baqaphe futhi balawule ukugeleza koketshezi olusuka emthonjeni ngaphandle kokudinga ukufinyelela ngokomzimba kumthombo womthombo.

Ngaphezu kokulawula ukugeleza koketshezi, isihlahla siphinde sisebenze njengendawo yokuxhumanisa imishini ehlukahlukene njengamashubhu okukhiqiza, ama-casing hangers, namadivayisi okulawula ukucindezela. Lokhu kuvumela uwoyela negesi ukuthi kukhiqizwe emthonjeni ngokuphepha nangempumelelo, kuyilapho kuhlinzeka nezindlela zokuqapha nokulawula ingcindezi ye-wellbore kanye nezinga lokushisa.

Ukuklanywa nokusebenza kwempahla yesihlahla sikaKhisimusi kubalulekile ekuqinisekiseni ukuphepha nobuqotho bomthombo. Izinto ezisetshenziswayo kufanele zikwazi ukumelana nokucindezela okuphezulu, uketshezi olubolayo kanye namazinga okushisa aphakeme kuyilapho zisanikeza ukulawula okuthembekile nokunembayo kokugeleza koketshezi emthonjeni. Lokhu kudinga ukuklanywa nokukhiqizwa ngokucophelela ukuze kuqinisekiswe ukuthi isihlahla singakwazi ukumelana nezimo ezinzima zomthombo.

Kafushane, izinto zokusebenza zesihlahla sikaKhisimusi zidlala indima ebalulekile ekubholeni umthombo, ukuqinisekisa ukukhiqizwa okuphephile nokuphumelelayo kwamafutha negesi. Izihlahla zikaKhisimusi ziyingxenye ebalulekile yemishini ye-wellhead ngokulawula ukugeleza koketshezi, ukuhlinzeka ngokufinyelela kokulungisa kanye nemisebenzi yokungenelela, kanye nokusebenza njengendawo yokuxhumanisa imishini ehlukahlukene. Ukuklanywa nokusebenza kwawo kubalulekile ekuqinisekiseni ukuphepha nobuqotho bomthombo, okwenza kube yisici esibalulekile ekuphumeleleni kokukhiqizwa kukawoyela negesi.
