I-oyile kunye negesi ye-Wellhead Production Equipment
Umthi weBhlokhi oMabini oLuqilima
Kwiintambo ezimbini zetyhubhu, umthi webhloko oqinileyo lolona qwalaselo lusetyenziswa kakhulu. Iinketho ezimbini ezibonisiweyo zezona ziyilo eziqhelekileyo. Iivalve ezilawula ukuhamba ukusuka kwindawo enzulu, umtya omde, ziivalve ezisezantsi emthini. Ngelixa kukho izinto ezingafaniyo kule ngqungquthela, ngaphandle kokuba umthi uphawulwe ngokucacileyo kunokucingelwa ukuba indawo yevalve ibonisa udibaniso lwe-subsurface.
Amacandelo aphambili enkqubo ye-wellhead are
intloko yebhokisi
i-casing spools
iihanger zecasing
iminxa ngokuphindaphindiweyo
packoffs (yedwa) izitywina
iiplagi zovavanyo
iinkqubo zokunqunyanyiswa kodaka
iintloko zeetyhubhu
imibhobho yokuxhoma
iadaptha yentloko yetyhubhu
Imisebenzi
· Ukubonelela ngeendlela zokunqunyanyiswa kwetyala. (I-Casing ngumbhobho ofakwe ngokusisigxina osetyenziselwa ukulungelelanisa umngxuma womthombo wokuthintela uxinzelelo kunye nokuthintela ukuwa ngexesha lesigaba sokomba).
· Ibonelela ngendlela yokunqunyanyiswa kwetyhubhu. (Iityhubhu ngumbhobho osusekayo ofakwe kwiqula ekudlula kulo ulwelo).
· Ibonelela ngendlela yokutywinwa koxinzelelo kunye nokwahlula phakathi kwecasing kumphezulu xa kusetyenziswa imitya emininzi.
· Ibonelela ngokujongwa koxinzelelo kunye nokumpompa ukufikelela kwi-annuli phakathi kweentambo ezahlukeneyo ze-casing/tubing.
· Ibonelela ngendlela yokuncamathelisa isithinteli sokuvuthela ngexesha lokomba.
· Ibonelela ngeendlela zokuncamathisela umthi weKrismesi kwimisebenzi yemveliso.
· Ubonelela ngeendlela ezithembekileyo zokufikelela kumthombo.
· Ubonelela ngeendlela zokuncamathisela impompo yequla.
Inkcazo
I-API 6A, uHlelo lwama-20, ngo-Oktobha 2010; Inkcazo yeWellhead kunye neZixhobo zoMthi weKrisimesi
ISO 10423:2009 Isixhobo seWellhead kunye neKrismesi yoMthi
Ngokubanzi iintloko zamaqula ngamaqondo amahlanu entloko yamaqula: 2, 3, 5, 10 kunye ne-15 (x1000) uxinzelelo lokusebenza lwePSI. Zinomgangatho wokushisa wokusebenza we -50 ukuya +250 degrees Fahrenheit. Zisetyenziswa ngokudibeneyo ne-ringi yodidi lwe-gaskets yotywino.
Ngokubanzi amandla okuvelisa avela kwi-36000 ukuya kwi-75000 PSI.
