2.1 Litlhoko tsa likarolo tsa mohloli oa khase
Ho laola likarolo tsa khase tse kenang pompong ea phetisetso, lintlha tse latelang li nahanoa haholo: (1) ho fihlela tlhokahalo ea boleng ba khase 'marakeng o shebiloeng, joalo ka ho khutlisa oli ea EOR, tlhokahalo e kholo ke ho fihlela litlhoko tsa motsoako- mohato oa ho khanna oli.②Ho fihlela litlhoko tsa phetisetso ea liphaephe tse bolokehileng, haholo ho laola likahare tsa likhase tse chefo joalo ka H2S le likhase tse senyang, ntle le ho laola ka thata ntlha ea phoka ea metsi ho netefatsa hore ha ho na metsi a mahala nakong ea phetiso ea lipeipi.(3) Ho ikamahanya le melao le melawana ea naha le ea lehae mabapi le tshireletso ya tikoloho;(4) Motheong oa ho finyella litlhoko tse tharo tsa pele, fokotsa litšenyehelo tsa phekolo ea khase holimo ka hohle kamoo ho ka khonehang.
2.2 Khetho le taolo ea boemo ba boemo ba lipalangoang
E le ho netefatsa polokeho le ho fokotsa litšenyehelo tsa ts'ebetso ea pipeline ea CO2, hoa hlokahala ho laola mokhoa oa liphaephe ho boloka boemo bo tsitsitseng nakong ea ts'ebetso ea phetisetso.E le ho netefatsa polokeho le ho fokotsa litšenyehelo tsa ts'ebetso ea liphaephe tsa CO2, hoa hlokahala ho qala ho laola mokhoa oa liphaephe ho boloka boemo bo tsitsitseng nakong ea ts'ebetso ea phetisetso, kahoo phetisetso ea khase kapa phetisetso ea boemo bo phahameng ka ho fetisisa e khethoa ka kakaretso.Haeba lipalangoang tsa khase li sebelisoa, khatello ha ea lokela ho feta 4.8 MPa ho qoba phapang ea khatello pakeng tsa 4.8 le 8.8 MPa le ho thehoa ha phallo ea mekhahlelo e 'meli.Ho hlakile hore bakeng sa liphaephe tse kholo le libaka tse telele tsa CO2, ho molemo ho sebelisa phetisetso ea supercritical ho nahanoa ka matsete a boenjiniere le litšenyehelo tsa ts'ebetso.
2.3 Tsamaiso le taolo ea sebaka
Khethong ea lipeipi tsa CO2, ntle le ho ipapisa le moralo oa mmuso oa lehae, ho qoba libaka tse sa tsotelleng tikoloho, libaka tsa ts'ireletso ea mesaletsa ea setso, libaka tsa likoluoa tsa jeoloji, libaka tse kopaneng tsa merafo le libaka tse ling, re lokela ho tsepamisa maikutlo holima sebaka se lekanyelitsoeng sa phaepe le metse e haufi, litoropo, liindasteri le likhoebo tsa merafo, libaka tse ka sehloohong tsa tšireletso ea liphoofolo, ho kenyeletsoa tataiso ea moea, sebaka, moea, joalo-joalo. le mehato ea temoso esale pele.Ha u khetha tsela, ho khothaletsoa ho sebelisa data ea remoutu ea sathelaete bakeng sa tlhahlobo ea ho koaheloa ha metsi, e le ho fumana sebaka se phahameng sa lipeipi.
2.4 Melao-motheo ea moralo oa kamore ea li-valve
E le ho laola palo ea ho lutla ha kotsi ea ho phatloha ha lipeipi e etsahala le ho nolofatsa tlhokomelo ea liphaephe, phaposi e khaohang ea liphaephe hangata e beoa sebaka se itseng pompong.Phapang ea kamore ea li-valve e tla lebisa ho palo e kholo ea polokelo ea liphaephe pakeng tsa kamore ea valve le palo e kholo ea ho lutla ha kotsi e etsahala;sebaka sa kamore ea li-valve se senyenyane haholo se tla lebisa keketseho ea theko ea mobu le matsete a boenjiniere, ha kamore ea li-valve ka boeona e boetse e tloaelehile sebakeng sa ho lutla, kahoo ha ho bonolo ho beha haholo.
2.5 Khetho ea ho roala
Ho ea ka phihlelo ea kantle ho naha ea ho haha lipeipi tsa CO2 le ts'ebetso, ha e khothalletsoe ho sebelisa seaparo sa ka hare bakeng sa tšireletso ea kutu kapa ho fokotsa ho hanyetsa.Seaparo se ka ntle sa anticorrosion se khethiloeng se lokela ho ba le ho hanyetsa mocheso o tlaase.Nakong ea ts'ebetso ea ho kenya pipeline ts'ebetsong le ho tlatsa khatello, lebelo la ho hōla ha khatello le hloka ho laoloa ho qoba ho phahama ho hoholo ha mocheso ka lebaka la ho eketseha ka potlako ha khatello, ho fella ka ho hlōleha ha ho roala.
