Momwe Mungasankhire Pulagi ya Bridge

Mapulagi a mlatho ndi zida zapadera zomangira zomwe zitha kukhazikitsidwa ngati zida zodzipatula kwakanthawi kuti zitengedwenso (zobweza) pambuyo pake kapena kuyikidwa ngati zida zomangira zokhazikika komanso zodzipatula (Zosavuta).

Zitha kuyendetsedwa pa waya kapena mapaipi opangidwa kuti akhazikikeposungira kapena tubing. Komanso, pali zitsanzo zomwe zimayikidwa mu casing koma zimatha kudutsa mu chingwe cha chubu.

Mapulogalamu a Bridge Plug

Pulagi ya mlatho imagwiritsidwa ntchito pamene:

• Malo amodzi kapena angapo okhala ndi perforated (kapena ofooka) ayenera kutetezedwa pansi pa malo omwe athandizidwa.
• Mtunda pakati pa malo ochitirako mankhwala ndi pansi pa chitsime ndi wautali kwambiri.
• Magawo angapo ndikusankha zone imodzi yothandizira ndi kuyesa ntchito kumaphatikizapo acidizing,hydraulic fracturing,casing simenti, ndi kuyesa.
• Chabwino Kusiyidwa.
• Ntchito Zokonza Simenti.

Pamene pulagi yobweza mlatho ikagwiritsidwa ntchito, imakutidwa ndi mchenga matope asanapope. Mwanjira iyi, imatetezedwa, ndipo simenti yowonjezereka mu khola imatha kutulutsa popanda kuiwononga.

Zofotokozera

• Ps amasankhidwa malinga ndi zinthu zotsatirazi:
• Kukula kwa casing, giredi & kulemera (9 5/8″, 7″, .....) zomwe zikhazikitsidwa.
• Max Chida OD.
• Kutentha.
• Kupanikizika.

Magawo & Mitundu Ya Bridge Plug

Pali magulu awiri akuluakulu a mapulagi a mlatho malinga ndi ntchito zawo:

• Drillable Type
• Mtundu Wobwezerezedwanso

Komanso, titha kuwagawa molingana ndi njira zawo zokhazikitsira:

• Wireline set mtundu
• Makina amtundu wa seti

Drillable Type

Mapulagi obowoleredwa nthawi zambiri amagwiritsidwa ntchito kulekanitsa choyikapo pansi pagawo loti chiwongoleredwe. Iwo ali ofanana mu kapangidwe ndiChosungira Simenti, ndipo akhoza kukhazikitsidwa pa waya kapena akubowola chitoliro.Mapulagi awa salola kuyenda kudutsa chida.

Mtundu Wobwezerezedwanso

Mapulagi obwezerezedwanso amayendetsedwa bwino ndi zida zogwiritsidwa ntchito ndi ntchito yofanana ndi mtundu wobowoleredwa. Nthawi zambiri amayendetsedwa paulendo umodzi (Tripping pipe) ndi Retrievable Packers ndipo amabwezedwa pambuyo pake simenti ikatulutsidwa. Ogwiritsa ntchito ambiri amawona mchenga wa frac kapena wosungunuka acidcalcium carbonate pamwamba pa pulagi yobweza musanachite ntchito ya simenti kuteteza simenti kuti isakhazikike pamwamba pa pulagi yobweza mlatho.

Pulogalamu ya Tubing Bridge

Pulagi ya thru-tubing bridge (TTBP) imapereka njira yotsekera madera ena (otsika) popanda kufunikira kochotsa machubu kapena kupha (njira yobowolera - Dikirani & njira yolemetsa) madera opangira apamwamba. Izi zimapulumutsa nthawi ndi mtengo, ndipo sipadzakhala kufunikira kopangira. Imasindikiza pachitsimecho ndi gawo la rabara lokulitsa kwambiri lomwe limatha kudutsa mu chubu lomaliza ndikusindikiza mubokosi lomwe lili pansipa.

Pulagi ya mlatho imayikidwa ndi hydraulically kuti itha kuyendetsedwamachubu ozungulira kapena mawaya amagetsi (pogwiritsa ntchito chida choyikira mawaya amagetsi). Rabara yopumira imatha kukhazikitsidwa m'ma ID ambiri kuphatikiza chitoliro chopanda kanthu, zoboola, zomangira zotsekera, zowonera mchenga, ndi mabowo otseguka. Itha kugwiritsidwanso ntchito ngati kutsekera kocheperako kocheperako kapena kusiyidwa kwachitsime kosatha.

Mitundu Ina Pamsika

Mapulagi a Iron Bridge

Mapulagi a Iron bridge adapangidwa kuti azigwiritsidwa ntchito m'malo okwera kwambiri, kutentha komanso kukokomeza. Mapulagiwa amakhala ndi mapangidwe olimba ndipo amatha kukhazikitsidwa pogwiritsa ntchito machubu wamba kapena chida cholumikizira mawaya. Pulagi ili ndi valavu yodutsa mkati yomwe imalola kuti madzi azitha kuyenda papulagi ikafunika, ndikuteteza kutulutsa kulikonse kosafunika kapena kutuluka. Valve yamkati yodutsamo imalolanso kutsuka kwa zinyalala pakubweza, kuonetsetsa kuti pulagiyo ndi yodalirika ikakhazikitsidwa.

Mapulagi a Composite Bridge

Mapulagi a kompositi amapangidwa kuti azigwiritsidwa ntchito pomwe kutentha kwambiri ndi kupanikizika kulipo, koma atha kugwiritsidwanso ntchito m'malo otsika kwambiri. Pulagi yamtunduwu ndi yodalirika kwambiri ndipo imagwiritsidwa ntchito pomalizidwa bwino pomwe chosungiracho chiyenera kutetezedwa ku kuwonongeka kobwera chifukwa cha madzi akumunsi. Mapulagi a kompositi amakhala ndi chinthu chophatikizika cholongedza, chomwe chimapangitsa chisindikizo pakati pa pulagi ndi chotchingira chozungulira kapena chubu.

Mapulagi a WR Bridge

Mapulagi a WR amapangidwa kuti azigwiritsidwa ntchito pomwe kutentha kwambiri ndi zovuta zimakhalapo. Amakhala ndi mapangidwe apamwamba omwe amawalola kuti atengedwe mwachangu komanso mosavuta popanda zida kapena zida zowonjezera. Pulagi imakhala ndi zotchingira zapamwamba, pulagi mandrel, chinthu cholongedza, ndi zotsitsa zapansi. Akayikidwa, zotchingira zakumtunda zimakulirakulira ku khoma la casing kapena chubu pomwe zotsika zapansi zimagwira mwamphamvu. Panthawi yobwezeretsa, zigawozi zimagwira ntchito pamodzi kuti zitsimikizire kuti pulagi imakhalabe mpaka itachotsedwa.

Mapulagi a BOY Bridge

Mapulagi a BOY Bridge adapangidwa kuti azigwiritsidwa ntchito pomwe pali zovuta komanso kutentha kwambiri. Mapulagiwa amakhala ndi mapangidwe olimba omwe amawalola kukhazikitsidwa pogwiritsa ntchito machubu wamba kapena chida cholumikizira mawayilesi. Pulagi ili ndi valavu yolowera mkati yomwe imalola kuti madzimadzi aziyenda papulagi pakafunika, ndikuteteza kutulutsa kosafunika kapena kutulutsa. Ilinso ndi chinthu chophatikizika cholongedza, chomwe chimapanga chisindikizo pakati pa plug thupi ndi casing yozungulira kapena chubu.

Mitundu yosiyanasiyana ya mapulagi a mlatho opangidwa ndi gulu la Vigor imaphatikizapo mapulagi achitsulo chachitsulo, mapulagi ophatikizika, mapulagi osungunuka ndi Mapulagi a Wireline Set Bridge (Obwezeredwa). Mapulagi onse a mlatho akhoza kusinthidwa malinga ndi zosowa za makasitomala kuti akwaniritse malo ovuta a malo omanga. Ngati muli ndi chidwi ndi zida za pulagi ya Vigor's bridge, chonde musazengereze kulumikizana nafe kuti mupeze zogulitsa ndi ntchito zabwino kwambiri.
