Umehluko Phakathi Kwe-TCP Perforation Nokubhobozwa Kwekhebula

I-TCP iyi-Tubing edluliswa ukubhobozwa. Ukuze uyihlukanise ne-cable perforation, kuyisiko ukubiza i-cableless perforation. Inqubo yokusebenza ye-TCP perforating iwukuxhuma intambo yesibhamu esibhobozayo kanye nesiqhumiso ekugcineni okuphansi kakhulu kwepayipi likawoyela. Futhi isiqhushumbisi siyakuthokozela ukuqhunyiswa ukucindezela komhlabathi noma indlela yokunamathela, futhi isiqhumane sizodubula. I-projectile yokubhoboza ochungechungeni lwezibhamu iyaqhunyiswa. Izinhlamvu ezibhobozayo zikhipha izimbobo eziningi odongeni lomthombo wamafutha, futhi uwoyela ongahluziwe ekubunjweni kwawo udlula epayipini likawoyela liye phansi.

Ukubhobozwa kwe-TCP nokubhobozwa kwekhebula kunezinzuzo ezilandelayo.

(1) Ukubhobozwa kwengcindezi engalungile.

Ngemva kokuba isibhamu se-TCP perforating sigxiliwe phansi kwesendlalelo ukuze sigcwaliswe, ingcindezi engalungile ingakhiwa phakathi kwengcindezi yokubunjwa kanye nokucindezela komthombo. Ngemva kokuba isibhamu se-perforating siqhunyiswa, ingcindezi engalungile ikhiqiza amandla okubuyisela ngokushesha alawulekayo, ukukhiqizwa komthombo kawoyela kwanda.

(2) Ukuqedwa kokubhoboza okukodwa.

Ngemithombo yomfutho ophezulu kawoyela negesi, ukubhobozwa okungenakhebula ukudubula izendlalelo eziqondiwe eziningi ngesikhathi kanye nokukhiqizwa kokuhlola ngokushesha.

(3) Ukusebenza okuhlanganisiwe ngesikhathi esifanayo.

Ukubhoboza okungenakhebula kungahlanganiswa nabahloli bokwakheka abahlukahlukene kanye nemishini yokuhlola uwoyela, njengokuhlola, ukufakwa kwe-asidi kanye nokuvuselela okuncane kokuqhekeka.

(4) Intambo yesibhamu ingakhululwa.

Lapho intambo yesibhamu idinga ukukhululwa, i-joint yokukhulula ingakhipha isibhamu se-perforating entanjeni futhi iwele phansi komthombo.

(5) Ifanele ukubhobozwa kwemithombo emikhulu ethambekele, imithombo yamaqoqo kanye nemithombo evundlile.

(6) Ukulondeka okuhle.

Iziqhumane ezisetshenziswa ezinhlelweni zokubhoboza ezingenakhebula zihlukaniswa zibe umthelela wemishini noma ukuqhunyiswa kwengcindezi.

I-pyrotechnics esetshenzisiwe yimikhiqizo yomlilo engeyona ekagesi, egwema ithonya lezinto ezingaphephile ezifana nogesi omile kanye ne-stray current, futhi inokuphepha okuphezulu. Ukwengeza, njengoba imishini ye-wellhead ifakwe emthonjeni ngaphambi kokubhobozwa, ukulawulwa komthombo ophakeme wengcindezi kungaqinisekiswa, ikakhulukazi umthombo wegesi ophezulu oqukethe i-HZS. Imishini ye-wellhead yokukhiqiza igesi ifakwe phambi kwe-perforation, futhi i-perforation ihlolwe ngokuqondile futhi ikhiqizwa. Kuphephe kakhulu kunokusebenzisa isibhamu sekhebula ukubhoboza.

Ukubhobozwa kwe-TCP kunezinzuzo eziningi ngaphezu kokubhobozwa kwekhebula okuningi, kodwa futhi kunemikhawulo ethile, ebonakaliswa kulezi zici ezilandelayo.

(1) I-TCP perforation iqinile kakhulu ngenqubo.

(2) I-TCP perforating iyabiza ukwakha futhi kudla izinto eziningi kanye nemishini.

(3) Ukuwohloka kokusebenza kokuqhuma.

Ngesikhathi kwakhiwa i-TCP perforation, intambo yesibhamu ye-TCP ihlala enkambisweni ye-downhole futhi ihlala emthonjeni isikhathi eside kakhulu kunokukhishwa kwekhebula, okuholela ekulahlekelweni kwamandla okubangelwa ukubola okushisayo kwesiqhumane, kunciphisa umphumela webhomu lokubhoboza. Ngakho-ke, ezinye izici eziphelele kufanele zicatshangelwe ngesikhathi sokwakhiwa, njengezinga lokushisa elingaphansi kwembobo kanye nokucindezela kanye nezinketho ezifanayo zemishini yokubhoboza.

(4) Ukuphepha.

Nakuba i-TCP perforation igwema ithonya likagesi omile, ukusebenza kwe-TCP perforating kudinga abasebenzi abaningi kanye nemishini kunokusebenza okujwayelekile kokubhoboza ikhebula, ngakho-ke izindaba zokuphepha kufanele zigcizelelwe.

(5) Ukuthembeka kokwakhiwa.

I-TCP perforation ingasetshenziselwa izibhamu ezimbalwa noma ngisho namakhulu ezibhamu ngesikhathi esisodwa, futhi isikhathi sokubhoboza sisukela emashumini amamitha kuya kumamitha angamakhulu amaningana. Ngenxa yamathuluzi noma ama-opharetha, iyunithi yezinhlamvu zesibhamu esibhobozayo iyanqatshwa, ukuze kubangele ukulahlekelwa okungenakulinganiswa. Ngakho-ke, ukuthuthukisa ukutholakala kokwethembeka nokusebenza kahle kwe-perforation kuyindaba ebalulekile.

I-perforating gun system evela ku-Vigor ikhiqizwa futhi yenziwe ngensimbi ye-alloy alloy ephezulu, engasekela kokubili izindlela zokudlulisa i-WCP ne-TCP. I-Vigor iphinde yathuthukisa idizayini yesakhiwo sangaphakathi edizayini, enganikeza imiphumela engcono yokubhoboza kuzinhlelo zokusebenza zomhlaba wangempela emkhakheni. Njengamanje, izibhamu ezibhobozayo ezivela ku-Vigor zisetshenziswe emadolobheni ahlukahlukene emhlabeni jikelele, futhi ithimba lase-Vigor lihlale lithuthukisa ukwakheka komkhiqizo wethu kanye nokuthutha ukuze liqinisekise ukuthi imikhiqizo yethu ifika endaweni yamakhasimende isesimweni esihle kakhulu ngangokunokwenzeka. Uma unentshisekelo ngezibhamu ze-Vigor's perforating noma amanye amathuluzi okumba nokuqedela embonini kawoyela negesi, sicela ungangabazi ukuxhumana nami.
