Izinhlobo Zezibhamu Zokuqhunyiswa

I-Tubing Perforating Gun

Izibhamu ezibhoboza amashubhu zingasebenzisa amachibi engeziwe ngokungena kuzintambo eziningi zokukhiqiza kanye nokufinyelela ezindaweni zokukhiqiza ezengeziwe ngaphandle kokukhipha intambo yokuqedela emthonjeni. Ngaphezu kwalokho, ngeke kube nesidingo sokuthola i-workover noma i-drilling rig ukwenza umsebenzi onjalo njengoba singakwazi ukubhoboza ngokungenasici.

Izinzuzo

● Ukulawulwa okungcono komthombo kungafinyelelwa ngenxa yokuthi isipakishi namashubhu akhona ngesikhathi sokubhobozwa.

● Ivumela ukulingana okulinganiselwe ekwakhekeni.

● Amathuluzi okupakisha nawokuqedela/DST asemthonjeni ngesikhathi sokubhoboza.

● Ukulinganisela kusiza ekuhlanzeni izimbobo.

Ukubi

● Izibhamu ezinobubanzi obuncane bangaphandle namashaji amancane zizoba nokubhoboza okulinganiselwe.

● Kunesidingo sokusabalalisa izibhamu ukuze kuthuthukiswe ukusebenza kahle.

Umkhawulo webhalansi elinganiselwa ku-1000 psi.

● Umkhawulo wobude be-perforator ngobude bokugcoba, idivayisi yokumisa, izisindo ezingeziwe zokubhekana nokucindezela okuphezulu, kanye nendawo yokubeka ikhola.

Izinhlobo

Kunezinhlobo ezintathu eziyinhloko zezibhamu ze-thru tubing perforating:

● Izibhamu ezisebenzisa izithwali ezibuyiswa ngokugcwele.

● Labo abasebenzisa umugqa wenkampani yenethiwekhi obuyiselekayo izindleko zokusekela eziqukethwe ezimweni ezisebenzisekayo.

● Izibhamu lapho ikesi yokushaja namakepisi ehlukana khona abe izingcezu ezincane ngemva kokuqhunyiswa

Izibhamu Zesithwali Ezingenalutho Ezibuyiselwayo

Lezi izinguqulo ezincane zezibhamu ze-casing esingazisebenzisa ku-tubing, ngakho-ke sibe nosayizi wokushaja ophansi ongu-180, ngakho-ke, ukusebenza okungcono kakhulu kunazo zonke ezinye izibhamu. Banikeza kuphela u-0 o ngezigaba ngobuningi. kokungu-4spf kusibhamu esingu-2 1/8 ”OD kanye no-6spf kusibhamu esingu-2 7/8” OD. Ngenxa yokuma kwekheshi lezi zibhamu ezingaba nazo, kuzoba nesidingo samathuluzi okuqondisa noma okusabalalisa izindawo.

Izibhamu zenethiwekhi ezingenalutho zitholakala ngosayizi abahlukahlukene kusukela ku-30 ​​mm (1 3/16″) ukuya ku-73 mm (2 7/8″) ekusetshenzisweni kwamashubhu. Iyunithi yezinhlamvu encane yokuqedela (Izinhlobo zokuqedela) I-ID ikhawulela usayizi wesibhamu ofanelekile. Nokho, izibhamu ezincane ezifika ku-54 mm (2 1/8″) zinamandla alinganiselwe ngenxa yobukhulu bazo bomzimba. Lokhu kukhawulela ubude belayini yokushaja emise okumise.

Ngakho, ubude bendiza bunciphisa inani leziqhumane ekushajweni ngakunye. Ubuningi bokudubula obunamandla ngalezi zibhamu amashothi ayi-19 imitha ngayinye (amashothi ama-6 ngonyawo ngalunye). Singakwazi ukumisa izibhamu ze-thru ukuze zinikeze cishe noma yisiphi isigaba se-perforating. Ukungena kahle kwezindleko ezincane ezidutshulwa kuwo wonke umthombo cishe kuzovala ukuncipha kwesikhumba sejiyomethri ngenxa yokuhlukaniswa ngezigaba.

Isimiso Somsebenzi

Izibhamu ngokuvamile zisetshenziswa ngezigaba zero. Ngaphezu kwalokho, singabeka isibhamu ngomshini noma ngozibuthe ukuze sinciphise igebe phakathi kwesibhamu nepayipi le-casing. Izibhamu ezinkulu ezingama-73 mm (2 7/8″) zinikeza ukusebenza okuqhathaniswa nalokho okutholwe ngezibhamu ezincane ezisebenziseka kalula noma ezisebenziseka kalula. Ukusebenza kwawo kokungena kuvumela ukusetshenziswa kwawo ekucupheni okuzungeza ngezigaba noma okungu-360°, kunciphisa isikhumba sejiyomethri futhi kuthuthukise ukusebenza kokungena ngisho nalapho kuqhunyiswa kuwo wonke umgodi. Izibhamu zenkampani yenethiwekhi ezingenalutho zinciphisa umonakalo we-casing njengoba inkampani yenethiwekhi iqukethe amandla okuqhuma kanye nezingcezwana zesivinini esikhulu zamakesi eshaji anomumo.

Izibhamu zenethiwekhi ezingenalutho zisebenza kahle kakhulu kunezibhamu ze-capsule ekubhobhozeni izikhawu ezinde phakathi nokugijima ngakunye. Lokhu kungenxa yokuthi isisindo sesithwali sinciphisa isidingo sezisindo ezengeziwe. Kodwa-ke, izithiyo zemishini yokucindezela phezulu zikhawulela ubude besibhamu esiphezulu ngesikhathi esisodwa ukuze bufinyelele kumamitha ayi-10.

Izibhamu Ezicwebezelayo Ezisetshenziswa Kakhulu futhi Ezingabizi Kancane Nge-Thru Tubing

Izibhamu ezithengekayo nezingabizi kakhulu ziyatholakala ezinkampanini eziningi zesevisi ezibhobozayo ngaphansi kwamagama ahlukahlukene ohwebo futhi zihluka ngosayizi ukusuka ku-43 mm (1 11/16″) kuya ku-73 mm (2 7/8″). Ukusebenza kwawo kuvame ukudlula izibhamu ezingenalutho ezinosayizi ofanayo. Lezi zibhamu zihlanganisa amashaji amise okukodwa, ngasinye sisemkhumbini ohlukile wokucindezela osekelwa izintambo noma imicu yenkampani yenethiwekhi.

Lapho isibhamu sidubula emthonjeni, sibhidliza imikhumbi yokucindezela, engase yenziwe ngobumba, i-aluminium, noma insimbi, ibe izingcezu ezincane. Izibhamu ezingabizi kakhulu zingabuyisa izintambo ezisekelayo noma amapheshana, kodwa izibhamu ze-capsule ezisebenzisekayo ziyawachitha futhi zizishiye emthonjeni. Imfucumfucu ephakeme kakhulu kufanele iwele phansi komthombo, kodwa ukugeleza kokuqala kokuhlinzwa kungakhuphula. Emithonjeni echezuke kakhulu, ukungqubuzana kungase kuvimbele imfucumfucu ukuba yehlele emthonjeni, kubangele insimbi noma ezinye izinto eziyizicucu ukuba ziyiswe phezulu lapho umthombo ukhiqizwa.

Ukuze uvimbele ukulimala kokuklinywa, amavalvu okuphepha angaphansi komhlaba, kanye nemishini yokukhiqiza engaphezulu, kubalulekile ukuthatha izinyathelo zokugwema udoti. Ukugeleza okubuyela phezulu kuzoqukatha okokusebenza kwe-polymer okuminyana kancane kanye nezingcezwana zezinto ezivela kumkhumbi wengcindezi nekesi lokushaja elimise okwesimo. Lezi zingcezu ziqhutshwa amandla okuqhuma kanye nomthelela ku-casing, okwenza umonakalo omkhulu kanye nokugqwala okusheshayo. Ukuze uvimbele ukulimala kwe-casing ngokweqile, kufanele ukhawule usayizi wezibhamu ezibhoboza ishubhu zibe ngu-54 mm (2 1/8″).

Ububi

Izinhlobo zezibhamu ezinwebekayo nezinwebeka kancane zithathwa njengezinamandla kakhulu kuzo zonke izinhlobo. Kodwa-ke, izinzuzo abazinikezayo kufanele zicatshangelwe ngokumelene nezinkinga ezivelayo ngenxa yenani elibalulekile lemfucumfucu emgodini womthombo, amathuba okuba nomonakalo webhokisi odalwe amashaji anamandla kakhulu, kanye nokungabikho kwendawo ebiyelwe ukuze kuvalwe ukuqhuma.

Isibhamu esibhobozayo esakhiwe futhi sakhiqizwa ithimba le-Vigor R&D sikhiqizwa ngokuhambisana ngokuqinile nezinga le-SYT5562-2016, futhi singenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende, uma unentshisekelo ochungechungeni lwethu lwezibhamu ezibhobozayo, sicela ungangabazi thintana nathi ukuze uthole imikhiqizo yekhwalithi engcono kakhulu nokusekelwa okungcono kakhulu kwezobuchwepheshe.
