Ukuvuselela amanzi
1. IAcidification
Ukunyangwa kwe-Acidification kwimithombo yeoli ngumlinganiselo osebenzayo wokwandisa imveliso, ngakumbi kwiindawo zeoli ze-carbonate, ezibaluleke kakhulu.
I-Acidification kukugalela isisombululo se-asidi efunekayo kuluhlu lweoli ukunyibilikisa izinto zokuthintela ekubunjweni kufuphi nomzantsi wequla, ukubuyisela ukubunjwa kwi-permeability yayo yasekuqaleni, ukunyibilikisa amacandelo athile ekubunjweni kwamatye, ukwandisa i-pores yokwakheka, ukunxibelelana kunye nokwandisa. Ukwandiswa koluhlu lweefractures kwandisa iziteshi zokuhamba kweoli kunye nokunciphisa ukuchasana, ngaloo ndlela kwandisa imveliso.
2. Ukuqhekeka
I-Hydraulic fracturing yeereservoirs ze-oyile ibizwa ngokuba yi-oil fracturing okanye i-fracturing. Isebenzisa indlela yokuhanjiswa koxinzelelo lwe-hydraulic ukwahlula umaleko we-oyile ukwenza enye okanye iifractures ezininzi, kwaye yongeza i-proppant ukuyithintela ukuba ivale, ngaloo ndlela itshintsha iipropathi ezibonakalayo zomaleko we-oyile kunye nokufezekisa injongo yokunyusa imveliso yemithombo yeoli kunye nokwandisa. inaliti yemithombo yokutofa amanzi.
Ioli yokuvavanya
Ingcamango, injongo kunye nemisebenzi yokuvavanya ioli
Uvavanyo lweoyile kukusebenzisa iseti yezixhobo ezikhethekileyo kunye neendlela zokuvavanya ngokuthe ngqo ioyile, irhasi, kunye neengqimba zamanzi eziye zamiselwa ngokweendlela ezingathanga ngqo ezifana nokubhola, ukugawula, kunye nokugawulwa kwemithi, kwaye ufumane imveliso, uxinzelelo, ubushushu kunye neoyile kunye negesi. amanqanaba omaleko ekujoliswe kuwo. Inkqubo yezobuchwepheshe yegesi, iipropati zamanzi kunye nezinye izinto.
Injongo ephambili yovavanyo lweoyile kukufumanisa ukuba kukho ukuhamba kweoyile yeshishini kunye negesi kuluhlu oluvavanyiweyo kunye nokufumana idatha emele ukubonakala kwayo kwasekuqaleni. Nangona kunjalo, uvavanyo lweoyile luneenjongo ezahlukeneyo kunye nemisebenzi kumanqanaba ahlukeneyo okuhlola intsimi yeoli. Ukushwankathela, kukho iingongoma ezine ikakhulu:
Iinkqubo ngokubanzi zokuvavanya ioli
Emva kokuba kombiwe iqula, linikezelwa ukuze kuhlolwe ioli. Xa iqela lokuvavanya i-oyile lifumana isicwangciso sovavanyo lwe-oyile, kufuneka liqale liqhube uphando lwemeko ye-well condition. Emva kwamalungiselelo afana nokumisa i-derrick, ukuthunga intambo, ukuthatha umgca, kunye nokukhupha umbhobho weoli wokulinganisa, ukwakhiwa kunokuqalisa. Ngokubanzi, uvavanyo oluqhelekileyo lweoyile, inkqubo yokuvavanya i-oyile epheleleyo ibandakanya ukuvulwa kakuhle, ukubulawa kakuhle (ukucoca kakuhle), ukutyhoboza, ukutyhoboza, umtya wombhobho osebenzayo, inaliti yokutshintshwa, inaliti eyenziweyo kunye ne-drainage, ukufuna imveliso, ukulinganisa uxinzelelo, ukutywinwa kunye nokubuya, njl. Xa iqula lisangaboni ukuhamba kwe-oyile nerhasi emva kwenaliti eyenzelweyo kunye ne-drainage okanye inemveliso ephantsi, kuyafuneka ngokubanzi ukuthatha i-asidi, i-fracturing kunye namanye amanyathelo okunyusa imveliso.
