Iyini i-Wireline Conveyed Perforating

I-Wireline edluliswa i-perforating iyindlela emisiwe, efakazelwe yokwethembeka okungangabazeki. Imvamisa iyona eshibhe kakhuluindlela yokubhobozaamasu futhi enokwethenjelwa kakhulu kunezinye izindlela. Imiphumela yokudubula kabi incishiswa kalula lapho izibhamu zingakhishwa khona embobeni ziphinde zigijime. Ngenxa yesisindo sesibhamu, isikhawu esilinganiselwe kuphela esingabhobozwa phakathi nokugijima ngakunye emgodini.

Izikhawu ezinde kufanele zigcwaliswe ngama-run amaningi, okungawokuqala kuphela angenziwa ngaphansi kwezimo ezikahle zokulinganisela. Kuye ngokujula nokunye ukucatshangelwa, njengokulibaziseka ekutholeni ukuthula komsakazo noma imikhawulo esemthethweni yokusebenzisa iziqhumane ebusuku, isikhathi sokusebenza esidingekayo ngokugijima ngakunye singahluka kusukela ngaphansi kwehora kuya emahoreni ambalwa.

Ngakho-ke, ukubhoboza izikhawu ezinde ngezibhamu zocingo kungathatha izinsuku ezimbalwa, okungase kubize kakhulu uma isikhonkwane sisendaweni. Ukusetshenziswa kwezibhamu zocingo kuyindlela ephephe kunazo zonke yokubhoboza etholakalayo, enezigameko ezimbalwa ezibikiwe zokuqhunyiswa kungahlosiwe kungaba phezulu noma phansi. Ukubhoboza okudluliswa ngocingo akudingi mshini esizeni futhi kuvame ukusetshenziselwa ukubhoboza izindawo ezengeziwe zokukhiqiza imithombo.

I-Perforating Gun Assembly & Mechanism

Ukuhlanganiswa kwesibhamu esimboza izintambo kuhlanganisa ikhanda lekhebula, indawo yokubuka ikhola noma ithuluzi le-gamma ray, kanye nemishini yasentwasahlobo noma kazibuthe yokubeka isibhamu kumgodi kanye nesibhamu ngokwaso. Izinhlobo ezine eziyinhloko zezibhamu ze-wireline perforating zingahlukaniswa futhi zikhonjiswe ku-Fig. Zonke ziyafana ekusebenzeni futhi zihluka kuphela endleleni izingxenye ezihlanganiswa ngayo.

Ikhanda Lekhebula

Ikhanda lekhebula lihlinzeka ngoxhumano lwemishini nogesi phakathi kwekhebula nesibhamu. Uxhumano lwemishini phakathi kwekhebula nekhanda lubuthakathaka kunekhebula ngokwayo ukuvumela intambo ukuthi idonswe ngokukhululeka uma isibhamu siba namandla.wabhajwa emgodini. Ngokuvamile kubizwa ngokuthi indawo ebuthakathaka. Ikhanda lekhebula lenziwe ngentamo enephrofayili ukuvumela okujwayelekileimishini yokudobaukubuyisela izintambo zamathuluzi uma iphuzu elibuthakathaka liphulwa. Ngobaizibhamu zebhokisisebenzisa ikhebula elikhulu, le ntamo inephrofayili ebushelelezi ukuvumela ukuzibandakanya ngeukudubuleka/ukuhlangana kwempi. Ngokuphambene, intamo evamile yokudoba ngocingo inikezwa izibhamu ezinobubanzi obuncane.

Indawo Yekhola Ekulayini Idluliselwe Ukubhoboza

Isitholi sekhola noma ithuluzi le-gamma ray libeka isibhamu ekujuleni okunqunywe ngokunembile okuhlobene nezilinganiso zelogi enembobo evulekile noma izingxenyekazi zekhompuyutha zokuqedela. I-Gamma-ray amathuluzi zisetshenziswa kancane ngenxa yemvelo yazo entekenteke kanye nokulula okuhlobene lapho ikhola yelogi ingasetshenziselwa ukuhlanganisa ukujula. Ngokuvamile, ithuluzi le-gamma ray nesitholi sekhola (GR-CCL) zisetshenziswa ngokuhlanganiswa ngaphambi kokugijima kwe-perforating ukuze kuvunyelwe ukujula okunembile.ipayipi lebhokisiamakholomu ahlobene namalogi okuhlola imbobo evulekile azonqunywa.

Isidingo sokugijima okwengeziwe kwe-GR-CCL singagwenywa ngokuqinisekisa ukuthi ithuluzi le-gamma ray lihlanganiswaibhondi kasimende logyokukhiqiza uhlobo lwebhokisi. Ukujula kwekhola kusetshenziselwa ukulungisa amaphutha ezilinganisweni ezijulile ezenziwe ngenkathi kusetshenziswa isibhamu esibhobozayo emgodini. Ake sithi ilogi ye-gamma ray enembobo evulekile ayinalo uhlamvu olwanele lokuvumela ukuhlobana nekhola yelogi yebhokisi.

Kuleso simo, kungase kudingeke ukuqhuba ilogi ye-neutron nge-collar log ye-casing ukuze kutholakale ukujula kwamakholomu e-casing. Ubunzima bokuhlobanisa ukugijima kwelogi yekholomu ehlukene kungaholela emaphutheni ekuhlonzeni amakholomu angawodwana lapho wonke amalunga e-casing afana kakhulu ngobude. Ngakho-ke, kuyisiko ukusebenzisa ilunga elifushane (ilunga lomdlwane) entanjeni ye-casing phezulu kwesikhawu se-reservoir. Lokhu kuqinisekisa ukuthi amakholomu e-casing abonakala kalula futhi ngokushesha, okunciphisa ingozi yokujula ngokujulile.

Idivayisi yokuma

Ngezibhamu ezincane ezinobubanzi, ezingabhobhozi ngo-360°, amathuluzi okumisa abekwe ngaphansi kwendawo yokubeka ikhola ukuze kuqinisekiswe ukuthi isibhamu sibheke ohlangothini olulungile lwe-azimuthal emgodini womthombo. Lapho sidutshulwa, ukuma kwe-azimuthal yesibhamu emthonjeni kuzonquma ibanga phakathi koketshezi lomthombo laphoukushaja okumiseijethi kufanele ihambe ngaphambi kokungena ebhokisini.

Ngokuvamile, leli banga kufanele lincishiswe ukuze kuzuzwe ukungena okuphezulu kokubunjwa kanye nokusebenza kahle kokubhoboza. Kusetshenziswa i-spring noma idivayisi kazibuthe ukuze kuqinisekiswe ukuthi isibhamu sibanjwe ngokumelene ne-casing, okunciphisa ukuma phakathi komzimba wesibhamu kanye nekesi elibheke lapho kudutshulwa khona. Ngokubhobhoza, ukubhobozwa kwezindawo ezingenhla ze-aukuqedwa okuningikudinga ukuthi amashothi adutshulwe ngomumo ogwema ukulimala kwentambo yokuqedela ende.

I-Wireline Idlulise Isibhamu Esiqhumayo

Isibhamu sibekwe ngaphansi komhlangano we-perforating. Isibhamu siqukethe isiqhushumbisi esicushwe ngogesi, noma isivalo sokuqhuma, esixhunywe ekugcineni kweshubhu leziqhumane ezaziwa ngokuthi intambo eqhumayo noma intambo yokuqala . Intambo eqhumayo ihamba ubude besibhamu. Ithintana ngokomzimba nenani ngalinye lezindleko ezinomumo.

Lapho isibhamu siqhunyiswa, isivalo esiqhumayo siqala ukuqhunyiswa kwentambo ye-prima, okubuye kusebenze icala ngalinye elimise. Ezibhamuni zokuphatha ezingenalutho, ikepisi eliqhumayo libekwa ngaphansi kwesibhamu, futhi isibhamu siqhunyiswa kusuka phansi kuya phezulu. I-detonator ngeke iqale i-primacord uma uketshezi lukhona ngenxa yokuvuza, ukuvimbela ukuqhunyiswa kwe-oda eliphansi nokuhlukaniswa kwesibhamu okungaholela. Izibhamu zohlobo lwe-capsule ezithengekayo nezingabizi kakhulu zinekepisi eliqhuma phezulu futhi zidutshulwa kusukela phezulu kuya phansi. Ake sithi isikhawu esiqhubekayo sizobhobozwa.

Kuleso simo, izingxenye zezibhamu ngokuvamile zixhunywa ndawonye nge-ballistically (lapho igagasi lokushaqeka kwe-detonation yesigaba esisodwa sesibhamu liqala ngokuqondile ukuqhunyiswa kwesilandelayo) futhi lidutshulwa njengesibhamu esisodwa. Lapho izikhawu eziningi ezimfushane zizobhobozwa khona, izibhamu zingahlanganiswa futhi zigijime ndawonye bese zidutshulwa ngazinye ekujuleni okudingekayo. Umklamo wesibhamu ozoxoshwa ufezwa ngokusebenzisa ama-diode kanye nokushintsha kwemishini kusibhamu se-downhole.

Njengomkhiqizi ochwepheshile wokubhoboza izibhamu, uVigor utshale isikhathi esiningi nemali ku-R&D kanye nokukhiqizwa kwezibhamu ezibhobozayo, ukuze nje kunikeze amakhasimende ethu imikhiqizo yezibhamu ezihamba phambili emhlabeni. Kuze kube manje, isibhamu se-perforating esivela ku-Vigor sisetshenziswe ezindaweni eziningi zikawoyela eYurophu, eMpumalanga Ephakathi, e-Asia Ephakathi, eNingizimu Asia, eMelika nakwezinye izifunda, futhi siye saqashelwa kakhulu amakhasimende. Uma unentshisekelo yokumba ama-downhole, ukuqedwa, amathuluzi okugawula embonini kawoyela negesi, sicela ungangabazi ukuxhumana nathi ukuze uthole imikhiqizo yobuchwepheshe kakhulu kanye nenkonzo yekhwalithi engcono kakhulu.
