Reservoir stimulation
1. Acidification
Acidification kurapwa kwemafuta emafuta chiyero chinoshanda chekuwedzera kugadzirwa, kunyanya kune carbonate mafuta reservoirs, ayo ane kukosha kukuru.
Acidification ndeyekuisa jekiseni inodiwa asidhi mhinduro mumafuta ekunyungudutsa zvinhu zvinovharira muchimiro padyo nechepazasi petsime, kudzoreredza kuumbwa kune kwayo kwepakutanga permeability, kunyungudutsa zvimwe zvikamu mumatombo ekugadzira, kuwedzera kuumbwa pores, kutaurirana uye kuwedzera. Iyo yekuwedzera huwandu hwemafractures inowedzera kuyerera kwemafuta nzira uye inoderedza kuramba, nekudaro ichiwedzera kugadzirwa.
2. Kutsemuka
Hydraulic fracturing yemafuta reservoirs inonzi mafuta reservoir fracturing kana fracturing. Inoshandisa nzira ye hydraulic pressure transmission kupatsanura mafuta layer kuti iite imwe kana akati wandei mafractures, uye inowedzera proppant kudzivirira kuti isavhare, nekudaro ichichinja hunhu hweiyo mafuta layer uye kuzadzisa chinangwa chekuwedzera kugadzirwa kwematsime emafuta uye kuwedzera. jekiseni remajekiseni emvura matsime.
Edzai mafuta
Iyo pfungwa, chinangwa uye mabasa ekuyedzwa kwemafuta
Oiri kuyedzwa kushandisa seti yezvishandiso zvine hunyanzvi uye nzira dzekuyedza zvakananga mafuta, gasi, uye mvura zvitubu zvakatanga kutariswa nenzira dzisina kunangana sekuchera, kukora, nekutema matanda, uye kuwana kugadzirwa, kudzvanywa, tembiricha, uye mafuta negesi. mazinga emutsetse wechinangwa. Iyo tekinoroji maitiro egasi, zvivakwa zvemvura uye zvimwe zvinhu.
Chinangwa chikuru chekuyedzwa kwemafuta ndechekuona kana paine mafuta eindasitiri uye gasi kuyerera mune yakaedzwa layer uye kuwana data rinomiririra kutaridzika kwayo kwepakutanga. Nekudaro, kuyedzwa kwemafuta kune zvinangwa zvakasiyana uye mabasa pamatanho akasiyana ekuongorora kwemunda wemafuta. Kupedzisa, pane zvinonyanya zvibodzwa zvina:
General maitiro ekuongororwa kwemafuta
Kana tsime racherwa, rinopiwa kuti riongororwe oiri. Kana timu yekuongorora mafuta yagamuchira chirongwa chekuyedza mafuta, inofanirwa kutanga yaita ongororo yemamiriro ezvinhu. Mushure mekugadzirira kwakadai sekumisa derrick, kupinza tambo, kutora mutsara, uye kuburitsa pombi yemafuta yekuyera, kuvaka kunogona kutanga. Kazhinji, kuedzwa kwemafuta kwakajairwa, iyo yakanyatso kuzara yekuyedza maitiro emafuta anosanganisira kuvhura tsime, kuuraya mutsime (kucheneswa zvakanaka), perforation, pombi tambo inomhanya, kutsiva jekiseni, jekiseni rakashongedzwa uye dhiraivha, kutsvaga kugadzirwa, kuyera kudzvanywa, kuvhara uye kudzoka, nezvimwe. Kana tsime richiri kusaona kuyerera kwemafuta uye gasi mushure mekucheneswa jekiseni uye dhiraivha kana kuve nekushomeka kwechigadzirwa, kazhinji zvinodikanwa kutora acidification, fracturing uye mamwe matanho ekuwedzera ekugadzira.
