Ukuqonda indima yama-wellheads nezihlahla ekukhiqizeni uwoyela negesi

Emkhiqizweni kawoyela negesi,amakhandafuthiIzihlahla zikaKhisimusidlala indima ebalulekile ekuqinisekiseni ukuthi izinsiza zikhishwa phezulu ngokuphepha nangempumelelo. Ndawonye, ​​lezi zingxenye ezimbili zilawula ukugeleza kukawoyela negesi ukusuka emthonjeni kuya phezulu, okwenza kube yingxenye ebalulekile yanoma yikuphi ukusebenza kokukhiqiza.

I-wellhead iyisixhumi esibonakalayo esiyinhloko phakathi kwedamu elingaphansi komhlaba kanyeizinto zokusebenza ezingaphezulu.Ifakwe phezu kwekahle casingfuthi inikeza uphawu olumelana nokucindezela ukuze luqukathe uketshezi ngaphakathi komthombo. I-wellhead nayo ifakwe ama-valve ahlukahlukene nokufakwa ukulawula nokuqapha umthombo ngesikhathi sokukhiqiza nokugcina imisebenzi.

Omunye wemisebenzi ebalulekile ye-wellhead ukusekela isisindo se-i-casing kanye ne-tubingintambo kanye nanoma yimuphi omunye umshini wokudonsa amanzi. Lokhu kusiza ukugcina ubuqotho bomthombo futhi kuvimbele noma yikuphi ukuvuza okungase kube khona noma ukuqhuma. Ngaphezu kwalokho, i-wellhead inikeza izindlela zokufaka nokubuyisela isihlahla sikaKhisimusi, okubalulekile ekulawuleni ukugeleza koketshezi emthonjeni.

Isihlahla sikaKhisimusi, esibizwa nangokuthi isihlahla sokukhiqiza, siyinhlanganisela eyinkimbinkimbi yamavalvu, i-instrumentation kanye nokuklinywa okubekwe phezu kwesihloko somthombo. Umsebenzi wawo oyinhloko ukulawula ukuhamba kukawoyela negesi yemvelo ukusuka emithonjeni kuya ezindaweni ezingaphezulu. Izihlahla zikaKhisimusi ziphinde zinikeze ukufinyelela kokungenelela kwemithombo, njengokusebenza kwezintambo kanye nokuqhekeka kwe-hydraulic, futhi zisebenza njengendawo yokuxhumana yokukhiqiza kanye nemigqa yomjovo.

Isihlahla sikaKhisimusi ngokuvamile siqukethe izingxenye eziningi, okuhlanganisa ama-valve amakhulu, ama-wing valves, ama-throttle valves kanye nama-gauge ahlukahlukene okucindezela. I-valve eyinhloko isetshenziselwa ukuhlukanisa umthombo endaweni engaphezulu futhi inikeza indlela yokuvala umthombo esimweni esiphuthumayo. Ama-valve amaphiko, ngakolunye uhlangothi, asetshenziselwa ukulawula ukugeleza koketshezi oluvela emthonjeni ukuze amazinga okukhiqiza akwazi ukulungiswa njengoba kudingeka.

Ama-throttle valves ayingxenye ebalulekile yesihlahla sikaKhisimusi futhi asetshenziselwa ukulawula ukugeleza kwamanzi ngokudala imingcele emgqeni wokukhiqiza. Lokhu kusiza ukulawula ingcindezi nokugeleza komthombo, kuqinisekisa ukukhiqizwa okuthuthukisiwe ngenkathi kugcinwa izimo zokusebenza eziphephile. Izikali zokucindezela ziqapha ingcindezi ye-wellhead ngesikhathi sangempela, okuvumela opharetha ukuthi benze izinqumo ezinolwazi mayelana nokukhiqiza nokuphepha.

Kafushane, izihlahla zemithombo kanye nezihlahla zikaKhisimusi zisebenza ndawonye ukuze zikhuthaze ukukhiqizwa okuphephile nokusebenzayo kukawoyela negesi. I-wellhead inikeza ukuxhumana okuphephile phakathi kwamadamu angaphansi komhlaba kanye nezinto zokusebenza ezingaphezulu, kuyilapho isihlahla sikaKhisimusi silawula ukugeleza koketshezi olusuka emthonjeni kuya endaweni yokukhiqiza. Ukuqonda imisebenzi yalezi zingxenye kubalulekile ekuqinisekiseni impumelelo yanoma yimuphi umsebenzi wokukhiqiza uwoyela negesi.
