Ukuvuselelwa kwedamu
1. Ukwenziwa kwe-asidi
Ukwelashwa kokufaka i-asidi ezinqolobaneni zikawoyela kuyisinyathelo esiphumelelayo sokwandisa umkhiqizo, ikakhulukazi ezinqolobaneni zikawoyela we-carbonate, okubaluleke kakhulu.
Ukufaka i-asidi kuwukufaka isisombululo se-asidi esidingekayo engqimbeni kawoyela ukuze kuncibilikiswe izinto ezivimbayo ekwakhekeni eduze kwaphansi komthombo, kubuyiselwe ukwakheka ekungeneni kwayo kokuqala, kuncibilikiswe izingxenye ezithile emadwaleni okwakheka, kwandiswe ama-pores okwakheka, kuxhunyaniswe futhi kwandiswe Ububanzi bokuqhekeka kwamafutha buyandisa iziteshi zokugeleza kwamafutha futhi kuncishiswe ukumelana, ngaleyo ndlela kwandiswe umkhiqizo.
2. Ukuqhekeka
Ukuqhekeka kwe-hydraulic kwama-oil reservoirs kubizwa ngokuthi ukuqhekeka kwe-oil reservoirs noma ukuqhekeka. Kusebenzisa indlela yokudlulisa ingcindezi ye-hydraulic ukuhlukanisa ungqimba lwamafutha ukuze kwakheke ukuqhekeka okukodwa noma okuningana, futhi kunezela i-proppant ukuze kuvinjwe ukuthi kuvaleke, ngaleyo ndlela kushintshe izakhiwo zomzimba zongqimba lwamafutha futhi kufezwe injongo yokwandisa ukukhiqizwa kwemithombo yamafutha nokwandisa ukujova kwemithombo yokujova amanzi.
Amafutha okuhlola
Umqondo, inhloso kanye nemisebenzi yokuhlola uwoyela
Ukuhlolwa kukawoyela ukusebenzisa isethi yemishini nezindlela ezikhethekile ukuhlola ngqo izendlalelo zikawoyela, igesi, namanzi ezinqunywe ekuqaleni ngezindlela ezingaqondile njengokubhoboza, ukufaka imigodi, kanye nokufaka izingodo, nokuthola amazinga okukhiqiza, ingcindezi, izinga lokushisa, kanye namazinga kawoyela negesi wezendlalelo eziqondiwe. Inqubo yobuchwepheshe yegesi, izakhiwo zamanzi nezinye izinto.
Inhloso eyinhloko yokuhlolwa kwamafutha ukuthola ukuthi kukhona yini ukugeleza kukawoyela negesi yezimboni ongqimbeni oluvivinyiwe nokuthola idatha emele ukubukeka kwawo kwasekuqaleni. Kodwa-ke, ukuhlolwa kwamafutha kunezinjongo nemisebenzi ehlukene ezigabeni ezahlukene zokuhlola insimu kawoyela. Ngamafuphi, kunamaphuzu amane ikakhulukazi:
Izinqubo ezijwayelekile zokuhlola uwoyela
Ngemva kokuba umthombo ubholiwe, unikezwa ukuze uhlolwe uwoyela. Lapho ithimba lokuhlola uwoyela lithola uhlelo lokuhlola uwoyela, kumele liqale lenze uphenyo ngesimo semithombo. Ngemva kokulungiselela okufana nokufaka i-derrick, ukufaka intambo entanjeni, ukuthatha umugqa, nokukhipha ipayipi lokulinganisa uwoyela, ukwakhiwa kungaqala. Ngokuvamile, ukuhlolwa uwoyela okuvamile, inqubo yokuhlola uwoyela ephelele ihlanganisa ukuvula umthombo, ukubulala umthombo (ukuhlanza umthombo), ukubhoboza, ukusebenza kwentambo yepayipi, ukufaka esikhundleni somjovo, ukujova kanye nokuphuma kwamanzi okubangelwa yimfucuza, ukufuna umkhiqizo, ukulinganisa ingcindezi, ukuvala nokubuyisela, njll. Uma umthombo ungakaboni ukugeleza kukawoyela negesi ngemva kokujova kanye nokuphuma kwamanzi okubangelwa yimfucuza noma ukhiqiza kancane, ngokuvamile kuyadingeka ukuthatha izinyathelo zokwandisa i-acid, ukuqhekeka kanye nezinye izindlela zokwandisa umkhiqizo.
