Ukukhuthazwa kwe-reservoir
1. I-Acidification
Ukwelashwa kokufakwa kwe-asidi ezinqolobaneni zikawoyela kuyisinyathelo esisebenzayo sokwandisa ukukhiqizwa, ikakhulukazi ezindaweni zokugcina amafutha e-carbonate, okubaluleke kakhulu.
I-Acidification iwukuba ujove isisombululo se-asidi esidingekayo ongqimbeni lwamafutha ukuze uhlakaze izinto ezivimbelayo ekubunjweni eduze nangaphansi komthombo, ukubuyisela ukwakheka ekungeneni kwayo kwasekuqaleni, ukuhlakaza izingxenye ezithile emadwaleni okwakheka, ukwandisa ama-pores okwakheka, ukuxhumana nokwandisa. Uhlu olunwetshiwe lwama-fractures lukhulisa iziteshi zokugeleza kwamafutha futhi lunciphise ukumelana, ngaleyo ndlela lukhulise ukukhiqizwa.
2. Ukuphuka
I-Hydraulic fracturing of oil reservoirs ibizwa ngokuthi i-oil reservoir fracturing noma i-fracturing. Isebenzisa indlela yokudlulisa ingcindezi ye-hydraulic ukuze ihlukanise ungqimba lwamafutha ukuze yenze ukuphuka okukodwa noma okuningana, futhi yengeza i-proppant ukuyivimbela ukuthi ingavali, ngaleyo ndlela iguqule izakhiwo ezingokomzimba zesendlalelo samafutha futhi ifeze inhloso yokwandisa ukukhiqizwa kwemithombo kawoyela nokwandisa. umjovo wemithombo yokujova amanzi.
Amafutha okuhlola
Umqondo, inhloso kanye nemisebenzi yokuhlola uwoyela
Ukuhlola uwoyela ukusebenzisa isethi yemishini ekhethekile nezindlela zokuhlola ngokuqondile izendlalelo zikawoyela, igesi, namanzi ekuqaleni ezinqunywa ngezindlela ezingaqondile njengokumba, ukuhlanganisa, nokugawulwa kwemithi, futhi kutholwe ukukhiqiza, ingcindezi, izinga lokushisa kanye nowoyela negesi. amazinga wesendlalelo esiqondiwe. Inqubo yezobuchwepheshe yegesi, izakhiwo zamanzi nezinye izinto.
Injongo eyinhloko yokuhlola uwoyela ukuthola ukuthi ingabe kukhona ukugeleza kukawoyela kwemboni negesi kungqimba oluhloliwe kanye nokuthola idatha emele ukubukeka kwayo kwasekuqaleni. Nokho, ukuhlolwa kukawoyela kunezinjongo nemisebenzi ehlukene ezigabeni ezihlukene zokuhlola indawo kawoyela. Ukufingqa, kunamaphuzu amane ngokuyinhloko:
Izinqubo ezijwayelekile zokuhlola uwoyela
Ngemva kokuba umgodi usubhodliwe, uyanikelwa ukuze kuhlolwe uwoyela. Uma ithimba elihlola uwoyela lithola uhlelo lokuhlola uwoyela, kufanele liqale lenze uphenyo lwesimo somthombo. Ngemva kwamalungiselelo afana nokumisa i-derrick, ukuhlanganisa intambo, ukuthatha umugqa, nokukhipha ipayipi likawoyela wokulinganisa, ukwakhiwa kungaqala. Ngokuvamile, ukuhlola uwoyela okuvamile, inqubo yokuhlola uwoyela ophelele uma kuqhathaniswa ihlanganisa ukuvulwa komthombo, ukubulawa komthombo (ukuhlanza kahle), ukubhoboza, ukugijima kwentambo yamapayipi, umjovo wokubuyisela, umjovo owenziwe kanye nokukhipha amanzi, ukufuna ukukhiqiza, ukukala ingcindezi, ukuvala uphawu nokubuya, njll. Uma umthombo ungakuboni ukugeleza kukawoyela negesi ngemva komjovo owenziwe kanye nokugeleza kwamanzi noma unokukhiqiza okuphansi, ngokuvamile kuyadingeka ukuthatha i-acidification, ukuphuka kanye nezinye izinyathelo zokwandisa ukukhiqizwa.
