Umsebenzi kunye naMalungu aPhambili ePacker

I-Packer sisixhobo esinomatshini esinento yokupakisha efakwe kwisixhobo esiyilelweyo, esisetyenziselwa ukuthintela unxibelelwano lwe-fluid (ulwelo okanye igesi) ngesithuba sonyaka phakathi kwee-conduits ngokuvala isithuba esiphakathi kwazo”.

Isipakishi sikholisa ukusetwa kanye ngentla kwendawo yokuvelisa ukwahlula isithuba sokuvelisa ukusuka kwi-annulus ye-casing okanye kwiindawo zokuvelisa kwenye indawo kumthombo.

Xa kugqityezelwa imingxuma enecala, ingxowa yemveliso iqhutywa kubo bonke ubude bequla kunye nedama. Umngxuma owenziweyo usebenza ngokufanelekileyo njengendlela yokulawula ukuveliswa ngokukhuselekileyo kweehydrocarbons ezifunwayo kwaye njengomqobo othintela ukubuyiselwa kolwelo olungafunwayo, iigesi, kunye nezinto eziqinileyo kumthombo womthombo.

Emva kokuba umtya we-drill ususiwe, ukudityaniswa okuqhubekayo kwee-casings zobubanzi obuhlukeneyo kuqhutyelwa emthonjeni kwiindawo ezinzulu ezihlukeneyo kwaye zikhuselekile ekubunjweni kwinkqubo eyaziwa ngokuba yi-Cementing. 'Isamente' apha ibhekisa kumxube wesamente kunye nezongezelelo ezithile ezimpontshelwa equleni kwaye zizalise ivacuum phakathi kwebhokisi kunye nokwakheka okujikelezileyo.

Emva kokuba umthombo wamanzi uvalwe ngokupheleleyo ekubunjweni okujikelezileyo, iqula kufuneka ligqojozwe ukuvuselela imveliso evela kumacandelo asebenzayo edama abizwa ngokuba 'yimimandla yokuhlawula'. Ukugqobhoza kwenziwa kusetyenziswa 'Imipu yokugqobhoza' ethi isuse uqhushumbo olulawulwayo oludubula imingxunya kumacandelo athile ebhobhothi (kunye nakwindawo yokugcina amanzi) ukwenzela ukuveliswa okulawulwayo kweehydrocarbons.

I-Parveen ibonelela ngomgca opheleleyo wabapakishi bemveliso kunye nezincedisi - ukusuka kubapakishi abasemgangathweni ukuya kuyilo olukhethekileyo kwezona ndawo zineentshaba. Iipakethi zethu zenzelwe ngokwe-API 11 D1 yoQinisekiso lweBanga le-V6-V0 kunye noLawulo loMgangatho weBanga le-Q3-Q1.

Imisebenzi yePacker: 

• Ukongeza ekuboneleleni ngetywina phakathi kwetyhubhu kunye ne-casing, eminye imisebenzi ye-packer yile ilandelayo:
• Thintela ukushukuma komngxuma ongezantsi womtya wetyhubhu, ukuvelisa i-axial tension okanye imithwalo yoxinzelelo kumtya wetyhubhu.
• Xhasa ubunzima obuthile betyhubhu apho kukho umthwalo ocinezelayo obalulekileyo kumtya wetyhubhu.
• Ivumela obona bungakanani bobona bungakanani bombhobho wokuqukuqela (umtya wetyhubhu) ukuhlangabezana nemveliso eyiliweyo okanye amanqanaba okumpompoza kwamanzi.
• Khusela i-casing yemveliso (intambo ye-casing yangaphakathi) kwi-corrosion evela kulwelo oluvelisiweyo kunye noxinzelelo oluphezulu.
• Inokubonelela ngeendlela zokwahlula imimandla yokuvelisa ezininzi.
• Bamba ulwelo olunika inkonzo kakuhle (ulwelo olubulalayo, ulwelo lwepaki) kwi-casing annulus.
• Ukuququzelela ukuphakamisa okwenziweyo, okufana nokuphakamisa igesi eqhubekayo nge-A-annulus.

Amacandelo aphambili ePacker:

• Umzimba okanye i-mandrel:

I-Mandrel iyona nxalenye ephambili ye-packer equlethe uxhulumaniso lokugqibela kwaye ibonelela nge-conduit nge-packer. Iphantsi kokuvezwa ngokuthe ngqo kulwelo oluqukuqelayo yiloo nto ukukhetha kwayo imathiriyeli kusisigqibo esibaluleke kakhulu. Eyona nto isetyenziswayo yi-L80 Type 1, 9CR, 13CR, 9CR1Mo. Kwiinkonzo ezigqwesileyo nezimuncu ngakumbi i-Duplex, i-Super Duplex, i-Inconel nazo zisetyenziswa ngokwemfuno.

• Iziliphu:

I-slip sisixhobo esine-wedge esine-wickers (okanye amazinyo) ebusweni baso, esingena kwaye sibambe udonga lwe-casing xa i-packer iseti. Kukho iintlobo ezahlukeneyo zoyilo lweziliphu ezifumaneka kubapakishi njengee-dovetail slips, uhlobo lwe-rocker slips bidirectional slips kuxhomekeka kwiimfuno zendibano yompakishi.

• Ikhowuni:

I-cone ifakwe kwi-beveled ukuze ihambelane nomva wesiliphu kwaye yenza i-ramp eqhubela isiliphu ngaphandle kunye nodonga lwe-casing xa ukuseta amandla kufakwe kwi-packer.

• Ukupakisha-into inkqubo

Into yokupakisha yeyona nto ibalulekileyo kuyo nayiphi na ipakethe kwaye ibonelela ngeyona njongo yokutywina. Nje ukuba iziliphu zibambelele eludongeni lwecasing, amandla ongeziweyo asetyenzisiweyo anika amandla inkqubo yokupakisha kwaye enze itywina phakathi komzimba opakishayo kunye nobubanzi bangaphakathi be-casing. Izinto eziphambili ezisetyenziswayo yi-NBR, i-HNBR okanye i-HSN, i-Viton, i-AFLAS, i-EPDM njl. njl umva ring inkqubo element.

• Tshixa umsesane:

Umsesane wokutshixa udlala indima ebalulekileyo kumsebenzi wompakishi. Injongo yendandatho yokukhiya kukudlulisa imithwalo ye-axial kunye nokuvumela ukunyakaza okungafaniyo kwezinto zokupakisha. Ikhonkco lokutshixa lifakwe kwizindlu zokutshixa kwaye zombini zihamba kunye phezu kwe-lock ring mandrel. Onke amandla okuseta aveliswe ngenxa yoxinzelelo lwetyhubhu atshixiwe kwipaki ngeringi yokutshixa.

Njengomnye wabavelisi abahamba phambili beepakethe, i-Vigor izinikele ekubekeni imigangatho yoshishino lomgangatho kunye nokuthembeka. Iinjineli zethu zizisa iminyaka yamava kwisicelo kunye nokusetyenziswa kwentsimi yabapakishi, esinika ulwazi oluxabisekileyo kwindima yabo ebalulekileyo kwimisebenzi eyimpumelelo yokomba. Siyaqonda ukuba umpakishi okumgangatho ophezulu unokuba nefuthe elibonakalayo kwimpumelelo kunye nokhuseleko, yiyo loo nto sihlala sityala imali kuphando nakuphuhliso. Injongo yethu kukuvelisa izinto ezintsha kunye nokuvelisa uthotho lwezisombululo zepakethe ezilungele ngokugqibeleleyo usetyenziso lwehlabathi lokwenyani.

E-Vigor, sibeka phambili iimfuno zabathengi bethu, siqinisekisa ukuba iimveliso zethu azihlanganisi nje kuphela kodwa zigqithise oko kulindelweyo. Ukuba unomdla ekujongeni uphuhliso lwethu lwamva nje lokupakisha okanye ezinye izixhobo zokugrumba umngxuma, siyakukhuthaza ukuba ufikelele. Iqela lethu leengcali likulungele ukukubonelela ngenkxaso yobuchwephesha kunye neemveliso ezikumgangatho ophezulu ezilungiselelwe iimfuno zakho. Impumelelo yakho ngumsebenzi wethu, kwaye silapha ukukunceda ukuba uwufezekise.
