Perforation yog txheej txheem tsim cov qhov hauv casing (los yog liner) los txuas lub reservoir nrog lub qhov dej zoo thiab cia cov hydrocarbons ntws mus rau hauv lub qhov dej. Perforating phom nrog tsub nqi yog siv los punch qhov nyob rau hauv zoo casing. Nyob rau hauv qhov chaw qhib-qhov, rab phom raug txo qis rau hauv qhov dej siv hluav taws xob-kab (E-line) lossis tubing. Cov phom yog khiav mus rau qhov xav tau qhov tob, tom qab ntawd pib txoj haujlwm perforation. Ntau lub tshuab phom sib txawv muaj rau kev xaiv, nyob ntawm qhov xav tau ntawm subsurface thiab perforation.
Muaj 3 txoj hauv kev loj thauj mus los txo cov phom perforating rau lub qhov dej, raws li hauv qab no:
1) Los ntawm-Casing Perforating yog siv ua ntej ua tiav qhov dej kom haum rau cov phom loj dua. Qhov loj ntawm rab phom yog ib txwm nyob nruab nrab ntawm 3 "thiab 5" nyob rau hauv txoj kab uas hla thiab yog khiav siv ib tug hlau-kab kab. Txoj kev perforating no yog siv los muab kev nkag mus ntau dua vim qhov loj ntawm cov phom loj. Ib yam nkaus, thiaj li hu ua "tsheb laij teb" kuj tseem tuaj yeem siv los tso cai rau cov phom khiav mus rau hauv qhov dej sib txawv. Ib qho ntawm cov kev txwv loj ntawm kev siv txoj kev no yog qhov xav tau zoo thiab kev xav tau siab, xws li thaum yuav tsum tau ua kom qis dua.
2) Tubing Conveyed Perforating (TCP) siv cov phom uas txuas nrog lub raj (xov yeeb, coiled tubing lossis cov tubing ntau lawm). Qhov zoo ntawm txoj kev no yog tias nws tso cai rau tawm hauv cov tubing ntau lawm hauv qhov dej, tom qab perforating tiav (khiav ua ke nrog ib txoj hlua ua tiav), ntev thiab dav spaced intervals, thiab daim ntawv thov nyob rau hauv heev deviated thiab kab rov tav qhov dej. Qhov teeb meem loj ntawm TCP phom yog kom txog thaum qhov ua tiav tau muab rov qab (tag nrho ua haujlwm dhau) phom tsis tuaj yeem rov qab tau. Yog li ntawd, kev ntseeg siab ntawm TCP phom yog qhov tseem ceeb tshaj plaws, vim tias txhua qhov tsis zoo yuav ua rau muaj kev ua haujlwm tsis zoo thiab cuam tshuam rau yav tom ntej cov ntaub ntawv ntau lawm.
3) Trough-tubing Perforating Phom yog phom, me me, siv hauv cov dej ua tiav thiab khiav los ntawm cov tubing ntau lawm. Lub kaw lus yog tus nqi qis thiab tso cai rau qhov sib npaug perforation, txawm li cas los xij muab kev nkag mus tau tsawg.
Phom systems poob rau hauv ob pawg tshwj xeeb:
1) Txhaum (Capsule) phom thiab
2) Hollow carrier phom. Txhua rab phom tau ua hluav taws xob ntawm qhov chaw thiab tuaj nyob rau hauv ntau qhov ntau thiab tsawg kom haum raws li qhov yuav tsum tau ua kom zoo.
