Igesi ehlobene ngokuvamile ibhekisela ku-symbiotic yegesi yemvelo namafutha. Ngokombono wokukhiqiza uwoyela we-organic hydrocarbon generation, lapho i-organic matter iguqukela esigabeni esivuthiwe, ama-hydrocarbon awuketshezi kanye namagesi akhiqizwa ngesikhathi esisodwa. Ezinye futhi ziqukethe amagesi angewona ama-hydrocarbon afana ne-carbon dioxide, i-nitrogen ne-hydrogen sulfide. Amagesi e-hydrocarbon angagcwalisiwe awavamile ukuqukethwa. Ama-hydrocarbons angama-gaseous angancibilika kuma-hydrocarbon awuketshezi noma akhona engxenyeni engenhla ye-reservoir esimweni se-gas cap.
Ngokombono we-organic oil generation, lapho i-organic matter iguqukela esigabeni esivuthiwe, ama-hydrocarbon awuketshezi nama-gaseous hydrocarbons akhiqizwa ngesikhathi esisodwa. I-gaseous hydrocarbon, noma incibilike ku-hydrocarbon ewuketshezi, noma ikhona engxenyeni engenhla yendawo yokugcina amanzi esesimweni sekhephu yegesi. Ibonakala ngokuthi okuqukethwe kwezingxenye ezingenhla kwe-ethane kuphakeme kunaleyo yegesi engahlobene, kanti ezinye futhi ziqukethe amagesi angewona ama-hydrocarbon afana ne-carbon dioxide, i-nitrogen ne-hydrogen sulfide, futhi ngokuvamile aqukethe amagesi ambalwa kakhulu e-hydrocarbon angagcwele. Igesi ehlobene ingasetshenziselwa ukukhiqiza igesi ye-petroleum ewuketshezi, uphethiloli kanye nezinto zokusetshenziswa zamakhemikhali.
Inhloso yokwelashwa kwegesi okuhlobene ukwelapha igesi ehlotshaniswayo etholiwe kanye negesi ezinzile, ukuze kukhiqizwe igesi ewuketshezi, i-hydrocarbon ekhanyayo ezinzile kanye negesi eyomile, kanye nokuthuthukisa ukusebenza kahle okuphelele kokusetshenziswa kwemithombo kawoyela negesi. Ukuze kuthuthukiswe izinga lokutholwa kwe-hydrocarbon ekhanyayo yegesi ehlobene, inqubo yokwelashwa kwegesi ehlobene nayo iyashintshwa kusukela kunqubo yokuhlukaniswa kwe-condensation engajulile yokucindezela okuphakathi kuya kunqubo yokumunca uwoyela obandayo ongashoni, futhi inqubo yokumunca uwoyela obandayo ithuthukiswa ngokuqhubekayo ukuze yakhe ubuchwepheshe bokugcina umbala bokwelapha igesi ehambisana ne-oilfield.
Isigaba I: inqubo yokupholisa yokucindezela okuphakathi nendawo - indlela yokuhlukaniswa kwe-condensation. Iyunithi yokuqala ehlanganisiwe yokutholwa kwe-hydrocarbon ekhanyayo yakhiwa esiteshini sokwelapha esimaphakathi sase-Maling ngo-Okthoba 1981. Isebenza kakhulu igesi ehambisanayo kanye negesi ezinzile ngaphandle kwesiteshi ukuze kukhiqizwe igesi ewuketshezi kanye nowoyela okhanyayo ozinzile. Inqubo yokupholisa ngomfutho omaphakathi - indlela yokuhlukaniswa kwe-condensation iyasetshenziswa. Iyunithi yavalwa ngo-1991. Inqubo yokupholisa ingcindezi emaphakathi - ukuhlukaniswa kwe-condensation kuyinqubo esetshenziswa kakhulu ukwelapha igesi ehlobene nendawo kawoyela kanye nokuthola i-condensate. Le nqubo yamukelwa kumayunithi alula wokutakula i-hydrocarbon elakhiwe ngaphambi kuka-2004.
Isigaba sesibili: inqubo yokupholisa yokucindezela okuphakathi nendawo - indlela yokumunca uwoyela obandayo. Ngemuva kuka-2004, inqubo yokupholisa yokucindezela okuphakathi nendawo - indlela yokumunca uwoyela obandayo izothuthukiswa. Isetshenziswe ngempumelelo kuyunithi yokubuyisela i-hydrocarbon ekhanyayo yesiteshi sokudlulisa amamitha e-WANGSHIBA okokuqala ngqa, ikakhulukazi ukwelapha igesi ehlobene ngaphandle kwesiteshi kanye negesi eguquguqukayo evela emathangeni kawoyela, futhi ikhiqiza igesi ewuketshezi nemikhiqizo kawoyela okhanyayo ozinzile. Uma kuqhathaniswa nendlela yokuhlukaniswa kwe-condensation, indlela yokumunca uwoyela obandayo inezici zokuvunwa okuphezulu kwe-C, inzuzo enhle yezomnotho, ukuguquguquka okubanzi kwenqubo kanye nokuguquguquka okukhulu kokusebenza. Inqubo yamukelwa kumayunithi alandelayo anegesi ehambisanayo njengegesi yokuphakelayo.
