Umkhakha kawoyela negesi uyindawo eyinkimbinkimbi futhi enobungozi obukhulu, lapho ukuphepha kanye nokusebenza kahle kwemisebenzi kubaluleke kakhulu khona. Ingxenye eyodwa ebucayi kulo mkhakha yi-valve ye-choke mantifold, edlala indima ebaluleke kakhulu ekulandiseni ukugeleza koketshezi ngesikhathi sokushayela nokungenelela kahle. Kulesi sihloko, sizohlola ukusetshenziswa kwama-valves ama-choke mantiford nokuthi basebenza kanjani ukuqinisekisa ukusebenza okubushelelezi nokuphephile kwemithombo kawoyela negesi.
Yini i-valve ye-choke minifold?
I-valve ye-choke manifold, njengoba igama libonisa, yingxenye esemqoka ye-choke michifold, ebhekele ukulawula ukugeleza koketshezi kusuka ku-Wellbore. I-Choke Mantifold ngumhlangano wama-valves nama-choke afakwe ku-rig yokumba ukuze alawule ukugeleza koketshezi kusuka emthonjeni. Kuyingxenye ebalulekile yohlelo lokulawula kahle, eklanyelwe ukuvikela ama-blowaut neminye imicimbi eyingozi ngesikhathi sokushayela nokungenelela kahle.
Ukusetshenziswa kwe-choke manifold valve
Umsebenzi oyinhloko we-choke manifold valve ukulawula ingcindezi nokugeleza kwezinga lamanzi aphuma emthonjeni. Ngesikhathi sokusebenza kokushayela, uketshezi lokwakheka (uwoyela, igesi, namanzi) kulethwa phezulu ngentambo yokumba. Le khasiI-valve ye-choke manifoldisetshenziselwa ukulawula ukugeleza kwalawa manzi, okuvumela opharetha ukuthi alondoloze ingcindezi efiselekayo kanye nokugeleza kwezinga ngenkathi eshayela.
Uma kwenzeka kukhahlela (ukungenela okungazelelwe koketshezi e-Wellbore), i-choke manifold valve ibalulekile ekuphambukiseni ukugeleza koketshezi kude ne-rig futhi ivikele i-blowout. Ngokushintsha i-choke valve, opharetha angaphendula ngokushesha ocwaningweni lokucindezela kanye nokugeleza kwezinga, ukuphatha isimo sokulawulwa kahle kanye nokuqinisekisa ukuphepha kweRig kanye nabasebenzi.
Usebenza kanjani umsebenzi wokukhishwa?
Ukusebenza kwe-choke many kuhilela inhlanganisela yama-valve nama-choke asebenza ngokubambisana ukulawula ukuhamba koketshezi. Lapho uketshezi lokwakheka lufika ebusweni, badlula i-valve ye-choke manifold, efakwe nge-choke (idivaysi yokuvinjelwa) engashintshwa ukuze kulawulwe ukugeleza. I-choke valve ijwayele ukuklanywa ukubekezelela izimo ezisezingeni eliphakeme kanye nezimo zokushisa okuphezulu, okwenza kube lula ukusetshenziswa ezindaweni ezifuna ukumba.
I-Choke ManiFold futhi ifaka amanye ama-valve, njenge-valve ebulala kanye ne-valu, esetshenziswa ngokubambisana ne-choke valve ukuhlukanisa umthombo futhi alawule ukugeleza koketshezi. Lawa ma-valves asetshenziswa ngabasebenzi abaqeqeshiwe ababheka kakhulu ukucindezela kanye nokugeleza kwezinga lamanzi, okwenza ukulungiswa kwesikhathi sangempela ukuqinisekisa ukusebenza okuphephile futhi okusebenzayo.
Ngaphezu kwendima yayo ekulawuleni kahle, i-choke manifold valve nayo isetshenziswa ngesikhathi sokuhlola nokuqedwa kwemisebenzi. Ivumela opharetha ukuthi alinganise izinga lokugeleza kanye nengcindezi yoketshezi lokwakheka, ukuhlinzeka ngemininingwane ebalulekile yokuhlola ukuhlelwa kabusha nokuhlelwa kokukhiqiza.
Ukucatshangelwa Kwezokuphepha
Ukuphepha kubaluleke kakhulu embonini kawoyela negesi, kanye nokusebenza okufanele kwe-choke manifold valve kubalulekile ekuqinisekiseni ukuphepha kwemisebenzi yokumba. Ukulungiswa okujwayelekile kanye nokuhlolwa kwezinto ezikhukhile kubalulekile ukuvikela ukwehluleka kwemishini nokugcina ukulungela okusebenzayo.
Ngaphezu kwalokho, abasebenzi abasebenzaChoke MantifoldKufanele uqeqeshelwe ukuqeqeshwa okuqinile ukuphatha izimo zokulawula kahle. Kufanele bakwazi ukusebenza ngokusebenza kwe-choke manifold valve futhi bakwazi ukuphendula ngokushesha nangokunqumela uma kwenzeka ukukhahlela noma ezinye izinselelo ezilawulwa kahle.
Ekuphetheni, i-valve ye-choke manifold iyingxenye ebalulekile embonini kawoyela negesi, edlala indima ebalulekile ekuphetheni ukugeleza koketshezi ngesikhathi sokungenela nokungenelela kahle. Amandla awo okulawula umfutho kanye nokugeleza kwesilinganiso sokugeleza, kuhlanganiswe nobungcweti babasebenzi abaqeqeshiwe, kuqinisekisa ukusebenza okuphephile nangokufanelekile kwemithombo kawoyela negesi. Ukuqonda ukusetshenziswa nokusebenza kwe-choke manifold valve kubalulekile kunoma ngubani obandakanyeka ekuhlolweni nasekukhiqizweni kwamafutha negesi.
