I-oyile kunye neGesi ukuDalwa kunye neMveliso

I-oyile kunye nerhasi zenziwa ngokuphuma kwiintsalela zezinto eziphilayo ezibolile kwilitye lentlenga ecaleni kweeminerali zamatye.Xa la matye engcwatywa yintlenga engaphezulu, i-organic matter iyabola kwaye iguqukele kwi-oyile kunye negesi yendalo ngokusebenzisa iinkqubo zebhaktheriya kunye nobushushu obuphezulu kunye noxinzelelo.Ngaphaya koko, i-oyile kunye nerhasi kunye namanzi ziyafuduka ukusuka etyeni ukuya kwilitye elikufuphi ne-porous reservoir (elidla ngokuba ngamatye entlabathi, i-limestone, okanye i-dolomites).Intshukumo iyaqhubeka de badibane nelitye elingenamanzi.Ngenxa yokwahlukana kobuninzi, igesi ifumaneka phezulu ilandelwa yioli kunye namanzi;Indawo yokugcina i-oyile iboniswe kuMfanekiso 1-2 obonisa iileya ezahlukeneyo ezenziwe ngerhasi, ioli kunye namanzi.

Emva kokuhlolwa kweoli kunye nenkqubo yokugaya iphunyeziwe, ngexesha lokuveliswa kweoli kunye negesi, kukho iindlela ezintathu zokubuyisela ezahlukeneyo ezisetyenzisiweyo;iindlela eziphambili, eziziisekondari kunye nenqanaba eliphezulu.Kweyona ndlela iphambili yokubuyisela i-oyile inyanzeliswa kumphezulu luxinzelelo lwedama, kwaye iimpompo zingasetyenziswa xa uxinzelelo luncipha.Iindlela eziphambili zokubuyisela i-akhawunti ye-10% yemveliso yeoli [8].Xa uvimba uvuthwa kwaye ukuba akukho manzi akwi-akhwifa athathela indawo i-oyile evelisayo, amanzi okanye irhasi efakwe kwidama ukunyusa uxinzelelo, obu buchwephesha 2 baziwa njengokubuyisela okwesibini;kukhokelela ekufumaneni kwakhona kwe-20-40 % ye-oyile yoqobo kwindawo.Umzobo 1-3 unika inkcazo ecacileyo yeendlela zokubuyisela okwesibini.
