Ntchito ndi Zigawo Zofunikira za Packer

Packer ndi chida chamakina chokhala ndi chinthu cholongedza chomwe chimayikidwa muchotengera chopangidwa, chomwe chimagwiritsidwa ntchito kutsekereza kulumikizana kwamadzi (zamadzimadzi kapena gasi) kudzera mumpata wapakati pakati pa makoswe potseka danga pakati pawo ”.

Packer nthawi zambiri imayikidwa pamwamba pa malo opangirako kuti ilekanitse nthawi yopangira kuchokera ku casing annulus kapena kutulutsa madera kwina kwa chitsime.

M'mabowo omalizidwa, chosungirako chimayendetsedwa mozungulira chitsime chonse ndikudutsa m'madzi. Bowolo limagwira ntchito ngati njira yowongolera popanga bwino ma hydrocarboni omwe amafunidwa komanso ngati chotchinga chomwe chimalepheretsa kulowanso kwamadzi osafunika, mpweya, ndi zolimba m'chitsime.

Pambuyo pochotsa chingwe chobowola, kulumikiza kosalekeza kwa ma diameter amitundu yosiyanasiyana kumathamangitsidwa m'chitsime mozama mosiyanasiyana ndikutetezedwa ku mapangidwe mwanjira yotchedwa Cementing. 'Simenti' apa akutanthauza kusakaniza kwa simenti ndi zowonjezera zina zomwe zimaponyedwa m'chitsime ndikudzaza mpweya womwe uli pakati pa thumba ndi mapangidwe ozungulira.

Chitsimecho chikatsekeredwa kuchokera pamalo ozungulira, botolo liyenera kung'ambika kuti lipangitse kutulutsa kuchokera kugawo loyenera la dziwe lotchedwa 'pay zones'. Kuboola kumachitika pogwiritsa ntchito 'Perforating guns' yomwe imayambitsa kuphulika kolamulirika komwe kumaphulitsa mabowo kupyola m'magawo apadera a casing (ndi m'malo osungiramo madzi) kuti azitha kupanga ma hydrocarbon.

Parveen imapereka mndandanda wathunthu wazopakira ndi zowonjezera - kuchokera pamapaketi wamba kupita ku mapangidwe apadera am'malo ovuta kwambiri. Mapaketi athu adapangidwa molingana ndi API 11 D1 Validation Grade V6-V0 ndi Quality Control Grade Q3-Q1.

Ntchito za Packer: 

• Kuphatikiza pa kupereka chisindikizo pakati pa chubu ndi casing, ntchito zina za paketi ndi izi:
• Pewani kusuntha kwa pobowo kwa chingwe cha chubu, kutulutsa mphamvu ya axial kapena kupanikizana pa chingwe cha chubu.
• Thandizani ena mwa kulemera kwa chubu komwe kuli kolemetsa kwambiri pa chingwe cha chubu.
• Imalola kukula kokwanira bwino kwa njira yoyendetsera chitsime (chingwe cha chubu) kuti igwirizane ndi kapangidwe kake kapena kuchuluka kwa jakisoni.
• Tetezani chosungira chopangira (chingwe chamkati) ku dzimbiri kuchokera kumadzi opangidwa ndi kupanikizika kwambiri.
• Itha kupereka njira yolekanitsira magawo angapo opanga.
• Gwirani zamadzimadzi zomwe zimagwira bwino ntchito (kupha madzi, zamadzimadzi zopakira) mu casing annulus.
• Kuwongolera kukweza kochita kupanga, monga kukweza gasi mosalekeza kudzera mu A-annulus.

Zofunikira za Packer:

• Thupi kapena mandrel:

Mandrel ndi gawo lalikulu la paketi lomwe lili ndi zolumikizira zomaliza ndipo limapereka njira kudzera papaketi. Imakhudzidwa mwachindunji ndi madzimadzi oyenda chifukwa chake kusankha zinthu zake ndikofunikira kwambiri. Zida zomwe zimagwiritsidwa ntchito kwambiri ndi L80 Type 1, 9CR, 13CR, 9CR1Mo. Pazinthu zowononga komanso zowawasa Duplex, Super Duplex, Inconel amagwiritsidwanso ntchito malinga ndi zofunikira.

• Zoyenda:

Chombocho ndi chipangizo chopangidwa ndi mphero chokhala ndi zingwe (kapena mano) pankhope pake, zomwe zimalowa ndikugwira khoma la casing pamene choyikapo chiyikidwa. Pali mitundu yosiyanasiyana ya mapangidwe a masilipi omwe amapezeka mumapaketi ngati ma slip a dovetail, masilipi amtundu wa rocker bidirectional kutengera zomwe amapakira amafunikira.

• Mphuno:

Cone imakumbidwa kuti ifanane ndi kumbuyo kwa slip ndipo imapanga kanjira kamene kamathamangitsira kunja ndikulowa mukhoma la casing pamene mphamvu yoyika ikugwiritsidwa ntchito kwa wonyamula.

• Packing-element system

Packing ndiye gawo lofunikira kwambiri papaketi iliyonse ndipo limapereka cholinga choyambirira chosindikiza. Zotsalirazo zikangokhazikika pakhoma la casing, mphamvu yowonjezera yowonjezera imalimbikitsa makina olongedza zinthu ndikupanga chisindikizo pakati pa thupi lopakira ndi mkati mwake mwa casing. Zida zomwe zimagwiritsidwa ntchito kwambiri ndi NBR, HNBR kapena HSN, Viton, AFLAS, EPDM etc. Makina odziwika kwambiri azinthu ndi makina okhazikika amodzi okhala ndi mphete yowonjezera, magawo atatu azinthu okhala ndi mphete ya spacer, ECNER element system, Spring loaded element system, Pindani. back ring element system.

• Lock mphete:

mphete yokhoma imagwira ntchito yofunika kwambiri pakupakira. Cholinga cha mphete yotsekera ndikutumiza katundu wa axial ndikulola kusuntha kwa unidirectional kwa zigawo zonyamula. The loko mphete anaika mu loko mphete nyumba ndi onse kuyenda pamodzi pa loko mphete mandrel. Mphamvu zonse zokhazikitsidwa chifukwa cha kukakamiza kwa chubu zimatsekeredwa mu paketi ndi mphete ya loko.

Monga m'modzi mwa otsogola opanga mapaketi, Vigor adadzipereka pakukhazikitsa miyezo yamakampani kuti akhale odalirika komanso odalirika. Akatswiri athu amabweretsa zaka zambiri pakugwiritsa ntchito komanso kugwiritsa ntchito mapaketi, zomwe zimatipatsa chidziwitso chamtengo wapatali pa ntchito yawo yofunika kwambiri pakubowola bwino. Timamvetsetsa kuti paketi yapamwamba kwambiri imatha kukhudza kwambiri magwiridwe antchito ndi chitetezo, ndichifukwa chake timayika ndalama zambiri pofufuza ndi chitukuko. Cholinga chathu ndi kupanga zatsopano ndikupanga mayankho angapo apaketi omwe ali oyenererana ndi ntchito zenizeni padziko lapansi.

Ku Vigor, timayika patsogolo zosowa za makasitomala athu, kuwonetsetsa kuti zinthu zathu sizimangokwaniritsa zomwe tikuyembekezera. Ngati mukufuna kudziwa zaposachedwa zapacker kapena zida zina zoboola pansi, tikukulimbikitsani kuti mulankhule nawo. Gulu lathu la akatswiri ndi okonzeka kukupatsirani chithandizo chaukadaulo chaukadaulo ndi zinthu zapamwamba kwambiri zogwirizana ndi zomwe mukufuna. Kupambana kwanu ndi ntchito yathu, ndipo tili pano kukuthandizani kuti mukwaniritse.
