Ho phunyeha ke mokhoa oa ho etsa masoba ka har'a casing (kapa liner) ho hokahanya letamo le seliba le ho lumella hydrocarbon hore e phalle ka selibeng. Lithunya tse phunyeletsang tse nang le litefello li sebelisetsoa ho phunya masoba ka mokotleng oa seliba. Sebakeng sa lesoba le bulehileng, lithunya li theoleloa ka selibeng ho sebelisoa mohala oa motlakase (E-line) kapa li-tubing. Lithunya li mathela botebong bo lakatsehang, ka mor'a moo mosebetsi oa ho phunyeletsa o qala. Ho na le litsamaiso tse ngata tse fapaneng tsa lithunya bakeng sa khetho, ho ipapisitse le litlhoko tsa bokaholimo ba lithunya.
Ho na le mekhoa e 3 e meholo ea ho tsamaisa lithunya ho theolela lithunya ka selibeng, joalo ka ka tlase:
1) Ka-Casing Perforating e sebelisoa pele ho phethoa seliba e le ho amohela lithunya tse kholoanyane tsa bophara. Boholo ba lithunya hangata bo pakeng tsa 3" le 5" ka bophara 'me bo tsamaisoa ka mohala oa mohala. Mokhoa ona oa perforating o sebelisetsoa ho fana ka ho phunyeletsa ho hoholo ka lebaka la boholo bo boholo ba lithunya. Hape, tse bitsoang "literekere" le tsona li ka sebelisoa ho lumella lithunya hore li kenngoe lilibeng tse khelohileng. E 'ngoe ea lithibelo tse kholo tsa ho sebelisa mokhoa ona ke maemo a matle le litlhoko tsa khatello, mohlala, ha ho hlokahala.
2) Tubing Conveyed Perforating (TCP) e sebelisa lithunya tse khomaretsoeng ho tubing (peipi ea ho phunya, li-tubing tse kopantsoeng kapa li-tubing tsa tlhahiso). Melemo e meholo ea mokhoa ona ke hore e lumella ho siea li-tubing tsa tlhahiso ka selibeng, ka mor'a hore ho phunyeletsa ho phethoa (ho matha hammoho le khoele ea ho qetela), nako e telele le e pharaletseng, le ho sebelisoa ka liliba tse khelohileng haholo le tse rapameng. Phello e kholo ea lithunya tsa TCP ke ho fihlela ho phethoa ho khutlisoa (lithunya tse felletseng) li ke ke tsa khutlisoa. Ka hona, ho ts'epahala ha lithunya tsa TCP ho bohlokoa ka ho fetesisa, kaha ho fosahala hofe kapa hofe ho tla baka mosebetsi o mobe mme ho ame haholo liprofinse tsa tlhahiso ea nako e tlang.
3) Lithunya tsa Perforating trough-tubing ke lithunya, tse nyane ka boholo, tse sebelisoang lilibeng tse phethiloeng 'me li tsamaisoa ka li-tubing tsa tlhahiso. Sistimi e theko e tlase mme e lumella ho phunyeha ho sa leka-lekaneng, leha ho le joalo e fana ka ho kenella ho lekanyelitsoeng.
Sistimi ea lithunya e arotsoe ka mekhahlelo e 'meli e ikhethileng:
1) Lithunya tse pepesitsoeng (Capsule) le
2) Lithunya tse se nang letho. Lithunya tsohle li thunngoa ka motlakase holimo 'me li tla ka boholo bo fapaneng ho lumellana le litlhoko tsa ho bolokoa hantle.
