Perforation inzira yekugadzira maburi mu casing (kana liner) yekubatanidza dura netsime rakaboora uye kubvumira mahydrocarbons kuti apinde mutsime. Pfuti dzinopisa dzine machaji dzinoshandiswa kubaya maburi mugomba retsime. Munzvimbo yakavhurika-gomba, pfuti dzinodzikiswa mutsime uchishandisa magetsi-line (E-line) kana tubing. Pfuti dzinomhanyiswa kuhupamhi hunodiwa, mushure mezvo basa rekubvisa rinotanga. A akati wandei akasiyana pfuti masisitimu aripo pakusarudzwa, zvichienderana nepasi pepasi uye perforation zvinodiwa.
Pane 3 nzira huru dzekufambisa dzekudzikisa pfuti dzinoputika kutsime, sepazasi:
1) Kuburikidza ne-Casing Perforating inoshandiswa isati yapera tsime kuitira kuti igare yakakura pfuti. Kukura kwepfuti kunowanzova pakati pe3"ne5" mudhayamita uye inomhanya uchishandisa waya-tambo. Iyi perforating nzira inoshandiswa kupa kupinda kukuru nekuda kwehukuru hukuru hwepfuti. Zvakare, anodaidzwa kuti "matarakita" anogonawo kuiswa kuti pfuti dzipinzwe mumatsime akatsauka. Chimwe chezvirambidzo zvikuru zvekushandisa nzira iyi kurerekera zvakanaka uye kudzvanywa zvinodiwa, semuenzaniso kana pasi-chiyero chinodiwa.
2) Tubing Conveyed Perforating (TCP) inoshandisa pfuti dzakanamirwa kune tubing (chibhorani pombi, coiled tubing kana kugadzira tubing). Mabhenefiti makuru eiyi nzira ndeyekuti inobvumira kusiya machubhu ekugadzira mugomba, mushure mekuputika kwapera (kumhanya pamwe chete netambo yekupedzisa), nguva refu uye yakaparadzana, uye kushandiswa mumatsime akatsauka uye akachinjika. Hombe dhizaini yeTCP pfuti kusvika kupedzisa kwadzoserwa (yakazara basa-pamusoro) pfuti haigone kutorwa. Nekudaro, kuvimbika kwepfuti dzeTCP kwakakosha zvakanyanya, sezvo chero kukanganisa kupi zvako kuchizokonzera kushomeka kwebasa uye kukanganisa zvakanyanya maprofile ekugadzira ramangwana.
3) Drough-tubing Perforating Pfuti pfuti, diki muhukuru, inoshandiswa mumatsime akapedzwa uye inomhanya kuburikidza nekugadzira tubing. Iyo sisitimu inodhura yakaderera uye inobvumira pasi-yakaenzana perforation, zvisinei inopa kushoma kupinda.
Pfuti masisitimu anowira mumapoka maviri akasiyana:
1) Yakafumurwa (Capsule) pfuti uye
2) Hollow carrier pfuti. Pfuti dzese dzinotungirwa nemagetsi pamusoro uye dzinouya mumhando dzakasiyana-siyana kuti dzienderane nezvinobhowa zvinodiwa.
