Umsebenzi kanye nezingxenye ezibalulekile zePacker

I-Packer iyidivayisi ewumshini enezinto zokupakisha ezifakwe kusitsha esiklanyelwe, esisetshenziselwa ukuvimba ukuxhumana koketshezi (uketshezi noma igesi) ngesikhala sonyaka phakathi kwamapayipi ngokuvala isikhala esiphakathi kwawo”.

I-Packer ivamise ukusetha ngaphezu nje kwendawo yokukhiqiza ukuze ihlukanise isikhawu sokukhiqiza kusukela ku-casing annulus noma ezindaweni ezikhiqizayo kwenye indawo emgodini womthombo.

Lapho kuqedwa imigodi enezimbobo, isikhwama sokukhiqiza siqhutshwa phakathi nobude bonke bomthombo kanye nedamu. Imbobo enekesi isebenza ngempumelelo njengendlela yokulawula yokukhiqizwa okuphephile kwama-hydrocarbons afiswayo futhi njengesithiyo esivimbela ukufakwa kabusha koketshezi olungadingeki, amagesi, nezinto eziqinile emgodini womthombo.

Ngemva kokuba intambo yokubhoboza isisusiwe, ukuhlangana okuqhubekayo kwama-casings amadayamitha ahlukene kufakwa emthonjeni ekujuleni okuhlukahlukene futhi kuvikelwe ekubunjweni ngenqubo eyaziwa ngokuthi i-Cementing. 'Usimende' lapha ubhekisela engxubeni kasimende nezinye izithasiselo ezimpontshelwa emthonjeni bese zivala isikhala esiphakathi kwebhokisi kanye nokwakheka okuzungezile.

Ngemva kokuba umthombo usuvaleleke ngokuphelele ekubunjweni okuzungezile, imbobo kufanele ibhodlozwe ukuze kukhuthazwe ukukhiqizwa okuvela ezingxenyeni ezisebenzayo zechibi elibizwa ngokuthi 'izindawo zokukhokha'. Ukubhoboza kwenziwa kusetshenziswa 'izibhamu eziqhumayo' eziqala ukuqhuma okulawulwayo okuqhumisa izimbobo ezingxenyeni ezithile zebhokisi (kanye nasechibini) ukuze kukhiqizwe ama-hydrocarbon okulawulwayo.

I-Parveen inikezela ngomugqa ophelele wabapakishi nezinto ezisetshenziswayo - kusukela kubapakishi abajwayelekile kuya kumiklamo ekhethekile yezindawo ezinobutha kakhulu. Amapaki ethu aklanywe ngokwe-API 11 D1 Ukuqinisekisa IBanga le-V6-V0 kanye neBanga Lokulawula Ikhwalithi Q3-Q1.

Imisebenzi ye-Packer: 

• Ngaphezu kokuhlinzeka ngophawu phakathi kweshubhu ne-casing, eminye imisebenzi ye-packer imi kanje:
• Vimbela ukunyakaza kwe-downhole kwentambo yeshubhu, ukhiqize ukungezwani okukhulu kwe-axial noma imithwalo yokucindezela entanjeni yeshubhu.
• Sekela esinye isisindo seshubhu lapho kunomthwalo ocindezelayo obalulekile entanjeni yeshubhu.
• Ivumela usayizi ophelele wepayipi eligeleza kahle (intambo yeshubhu) ukuhlangabezana nokukhiqizwa okuklanyiwe noma amazinga okugeleza komjovo.
• Vikela i-casing yokukhiqiza (intambo ye-casing yangaphakathi) ekugqwaleni emanzini akhiqizwayo kanye nokucindezela okuphezulu.
• Ingahlinzeka ngendlela yokuhlukanisa izindawo eziningi zokukhiqiza.
• Bamba uketshezi olusebenza kahle (uketshezi olubulalayo, uketshezi lwepaki) ku-casing annulus.
• Yenza kube lula ukuphakamisa okwenziwayo, njengokuphakanyiswa kwegesi okuqhubekayo ku-A-annulus.

Izingxenye ezibalulekile zePacker:

• Umzimba noma i-mandrel:

I-Mandrel iyingxenye eyinhloko yepaki equkethe ukuxhumana kokugcina futhi inikeza ipayipi ngokusebenzisa ipakethe. Ingaphansi kokuchayeka ngokuqondile oketshezini olugelezayo yingakho ukukhethwa kwayo kwempahla kuyisinqumo esibaluleke kakhulu. Izinto ezisetshenziswa kakhulu yi-L80 Type 1, 9CR, 13CR, 9CR1Mo. Ukuze uthole izinsiza ezibolayo nezimuncu kakhulu i-Duplex, i-Super Duplex, i-Inconel nayo isetshenziswa ngokwemfuneko.

• Iziliphu:

I-slip iyithuluzi elimise okwe-wedge elinezintambo (noma amazinyo) ebusweni bayo, elingena futhi libambe udonga lwe-casing lapho ipakethe isethiwe. Kunezinhlobo ezahlukene zemiklamo yeziliphu ezitholakala kumapaki afana neziliphu ze-dovetail, uhlobo lwe-rocker slips bidirectional slips kuye ngezidingo zokuhlanganiswa kompakishi.

• Ikhoni:

Ikhoni iboshwe ukuze ifane nengemuva lesiliphu bese yenza irempu eshayela isiliphu siphumele ngaphandle futhi singene odongeni lwe-casing lapho amandla okusetha asetshenziswa kumpakishi.

• Isistimu yokupakisha-elementi

I-elementi yokupakisha iyingxenye ebaluleke kakhulu yanoma imuphi umpakishi futhi inikeza injongo yokuqala yokuvala. Uma iziliphu sezigxilile odongeni lwe-casing, amandla engeziwe okusetha asetshenziswayo anika amandla isistimu ye-packing-elementi futhi enze uphawu phakathi komzimba wompakishi kanye nobubanzi bangaphakathi bebhokisi. Izinto ezisetshenziswa ngokuyinhloko yi-NBR, i-HNBR noma i-HSN, i-Viton, i-AFLAS, i-EPDM njll. Isistimu ye-elementi edume kakhulu isistimu ye-elementi eyodwa unomphela enendandatho yokunweba, isistimu yezingcezu ezintathu enendandatho yesikhala, isistimu ye-elementi ye-ECNER, isistimu ye-elementi elayishiwe yasentwasahlobo, Fold isistimu yesici sendandatho yangemuva.

• Khiya indandatho:

Indandatho yokukhiya idlala indima ebalulekile emsebenzini wompakishi. Inhloso yendandatho yokukhiya ukudlulisa imithwalo ye-axial nokuvumela ukunyakaza okukodwa kwezingxenye zamapaki. Indandatho yokukhiya ifakwe endlini yokukhiya futhi kokubili ukuhamba ndawonye phezu kwendandatho yokuvala i-mandrel. Wonke amandla okusetha akhiqizwe ngenxa yokucindezela kweshubhu akhiyelwa kumapaki ngendandatho yokukhiya.

Njengomunye wabakhiqizi abahamba phambili bamapaki, i-Vigor izinikele ekubekeni amazinga embonini ngekhwalithi nokuthembeka. Onjiniyela bethu baletha isipiliyoni seminyaka kukho kokubili ekusetshenzisweni nasekusetshenzisweni emkhakheni kwamapaki, okusihlinzeka ngemininingwane ebalulekile endimeni yabo ebalulekile ekusebenzeni okuphumelelayo kokumba. Siyaqonda ukuthi umpakishi wekhwalithi ephezulu angaba nomthelela omkhulu ekusebenzeni kahle nokuphepha, yingakho sitshala ngokungaguquki ocwaningweni nasekuthuthukisweni. Umgomo wethu uwukusungula nokukhiqiza uchungechunge lwezixazululo zamapaki ezilungele izinhlelo zokusebenza zomhlaba wangempela.

Kwa-Vigor, sibeka phambili izidingo zamakhasimende ethu, siqinisekisa ukuthi imikhiqizo yethu ayihlangani nje kuphela kodwa idlule lokho esikulindele. Uma ungathanda ukuhlola ukuthuthukiswa kwethu kwakamuva kwamapaki noma amanye amathuluzi okumba ama-downhole, sikukhuthaza ukuthi ufinyelele. Ithimba lethu lochwepheshe lilungele ukukunikeza ukwesekwa kobuchwepheshe obuchwepheshile kanye nemikhiqizo yekhwalithi ephezulu efanelana ngqo nezidingo zakho. Ukuphumelela kwakho kuwumsebenzi wethu, futhi silapha ukukusiza ukukufeza.
