Permanent Packer ndi Retrievable Packer

Permanent Packer

Zomangamanga zomwe zimatchulidwa kuti ndizokhazikika zimachotsedwa ku zitsime ndi mphero. Izi ndi zomangika zosavuta ndipo zimapereka kutentha kwakukulu ndi kupanikizika kwa ntchito. Kung'onozing'ono kwa kunja kwa mayunitsi okhazikika kumapangitsa kuti pakhale kutuluka kwapamwamba mkati mwa chingwe cha casing. Kumanga kocheperako kumawathandiza kuti azikambirana kudzera m'magawo opapatiza komanso apatuka omwe amapezeka pachitsime. Kukula kwawo kwamkati kumawapangitsa kukhala oyenera kugwiritsidwa ntchito ndi zingwe zamachubu za mainchesi ochulukirapo komanso kumaliza kwa monobore.

Amayendetsedwa ndikuyikidwa pogwiritsa ntchito mawaya amagetsi, mapaipi obowola, kapena machubu. Zikakhazikitsidwa, zinthuzo zimalephera kuyenda kuchokera mbali iliyonse. Zokonda pa mawayilesi zimatumiza mphamvu yamagetsi kuti ikhazikitse chopakiracho kudzera pakuphulika kwa chiphulika. Kenako chowotcha chimalekanitsa msonkhano ndi wopakira. Zinthu zokhazikika ndizoyenera zitsime zokhala ndi kuthamanga kwambiri kapena kusiyanasiyana kwamachubu.

Kubweza Packer

Zonyamula zobweza zimaphatikizanso mitundu yonse yanthawi zonse yotsika kwambiri / kutentha kwapang'onopang'ono (LP/LT) ndi mitundu yovuta kwambiri yothamanga / kutentha kwambiri (HP/HT). Zogulitsazi ndizokwera mtengo kwambiri kuposa zokhazikika zomwe zimapereka magwiridwe antchito ofanana chifukwa chazovuta zamapangidwe akamagwiritsa ntchito zida zapamwamba. Komabe, zinthu monga kumasuka kwa kuchotsa packer wellbore ndi kugwiritsiridwanso ntchito zimathandizira kuthetsa mtengo.

Zogulitsazo zimagawidwanso m'mitundu yosiyanasiyana, kuphatikiza:

Kuyika mwamakina: Kukhazikitsa kumachitika kudzera pakuyenda kwamachubu amtundu wina. Izi mwina zikuphatikiza kuzungulira kapena kutsika / pansi. Kuphatikiza apo, katundu umakhudzidwa pakukhazikitsa mayunitsi monga kulemera kwa chubu kumakakamira kapena kukulitsa chinthu chosindikizira. Kukoka chingwe kumatulutsa zinthu. Izi ndizofala kwambiri m'zitsime zosaya, zowongoka zomwe zimakhala ndi mphamvu yochepa.

Kukhazikika: Zinthu zopakira za kalasiyi zimayikidwa kudzera pakukoka kukanikiza komwe kumayikidwa pa chubu. Slack amathandizira kumasula chinthucho. Amagwira ntchito bwino m'zitsime zosaya zomwe zimakhala ndi kupsinjika kwapakati.

Seti yozungulira: Izi zimagwiritsa ntchito kuzungulira kwa machubu kuti akhazikitse ndi kutseka gawo lina.

Hydraulic-set: Gululi limagwira ntchito ndi kuthamanga kwamadzimadzi kumayendetsa cone m'malo kumbuyo kwa zotsalira. Pambuyo pokhazikitsa, loko loko yamakina kapena kukakamizidwa kotsekeka kumawapangitsa kuti asasunthike. Kunyamula tubing kumayendetsa ntchito yotulutsa.

Inflatable: Zomwe zimadziwikanso kuti swellable elements, zigawozi zimadalira kuthamanga kwamadzimadzi kuti afufuze machubu a cylindrical kuti awayike. Amapezeka poyesa maenje otseguka pobowola zitsime zowunikira komanso kutsimikizira simenti popanga zitsime. Ndiwoyeneranso ku zitsime zomwe onyamula ayenera kudutsa malire asanakhazikike m'mimba mwake mokulirapo m'mabowo kapena mabowo otseguka.

Kuyang'ana mwatsatanetsatane njira zina zodziwika bwino kumatsatira pansipa:

Zinthu zobwezerezedwanso zopakira zimathandizira kupanga kuya kwakuya kapena jekeseni. Izi zimakhala ndi zotsalira za unidirectional zomwe zimangogwira pa casing pakakhala zovuta pamachubu. Kuthamanga kwa chubu kumalimbitsa zinthu. Gululi limayikidwa mwamakina ndikumasulidwa ndi chubu kasinthasintha. Mitundu yambiri imabwera ndi kumasulidwa kwadzidzidzi ngati njira yoyamba yotulutsidwa ikalephera.

Ma tension packers amagwiritsidwa ntchito pomwe kupanikizika pansi kumakhala kokulirapo nthawi zonse kuposa kukakamiza kwa annulus komwe kuli pachidacho. Kuthamanga kokwera uku kumakakamiza zinthuzo kuti zigwirizane ndi slip kuti zisungidwe.

Zinthu zobwezeredwa zoponderezedwa zokhala ndi zodutsa madzimadzi ndizoyenera malo ocheperako komanso apakatikati amafuta ndi gasi pobowola kutentha kwapakati. Kulumikizana kwamakina kumapangitsa kuti gawo lisakhazikike. Pomwe imathamanga mu dzenje, kuzungulira kwa tubing kumayambitsa chinthucho. Kokani midadada yomwe ili pa chinthucho chigwireni ndikupereka kukana kofunikira kuti muyike. Cholumikiziracho chikatulutsidwa, kutsitsa chingwe cha chubu kumapangitsa kutseka kwa chosindikizira ndikuyika zotsetsereka. Kugwiritsa ntchito mphamvu mosalekeza kumapangitsa chisindikizocho popatsa mphamvu zinthuzo. Kutulutsa kumatheka pokoka chingwe cha chubu.

Njira iyi ili ndi kuthekera kwapadera kolimbana ndi zitsenderezo zokulirapo komanso kutentha kuposa njira zina zokakamira. Valavu yodutsa imapangitsa kuti wopakirayo azitha kufananiza zovuta zomwe zimapezeka mu chubu ndi annulus ndikupangitsa kuti zikhale zosavuta kumasula chidacho. Kupanikizika kosalekeza kapena kulemera kwa chubu ndikofunikira kuti valavu yodutsayo ikhale yotsekedwa. Izi sizoyenera pazitsime za jakisoni kapena maopaleshoni ochepetsa kuthamanga kwa voliyumu.

Kukanika kobwezeredwa/kuponderezana kumalimbikitsa kutsetsereka kwa machubu movutikira, kupsinjika, kapena kusalowerera ndale. Izi ndizofala kwambiri masiku ano zomwe zimakhazikitsidwa mwamakina. Amakhala ndi masinthidwe osiyanasiyana azovuta, kukanikizana, kapena kuphatikiza ziwirizo kuti akhazikitse ndikunyamula chinthu. Kusankhidwa kwa machitidwe ndi mavoti osiyanitsa zimapangitsa kuti zikhale zothandiza pazochitika zambiri. Ndi ma seti awa, mphamvu yopatsa mphamvu imatsekeredwa ndi makina otsekera mkati mpaka gawolo litatulutsidwa ndi valavu yodutsa. Valve iyi imathandiziranso pakufanana.

Zipangizozi zimakhala zosunthika kwambiri kuposa njira zina ndipo zimapezeka popanga ndi jekeseni.

Zomangira zokhazikika komanso zobwezeredwa za sealbore zimayikidwa ndi mawaya amagetsi kapena ma hydraulics pa chingwe cha chubu. Kukhazikitsa ndi mawayilesi kumapereka liwiro lowonjezereka komanso kulondola pomwe njira zoyika ma hydraulic-setting zaulendo umodzi zimapindula pakuyika chiphaso chimodzi. Amathandizira kukhazikitsa ndi ma wellheads flanged. Gululi lili ndi zopukutidwa zamkati zamkati. Chosindikizira cha chubu chokhala ndi zonyamula za elastomeric chimapanga chisindikizo cholumikiza machubu opangira ndi packer bore. Kuyika kwa zisindikizo za elastomeric mu bore kumapangitsa kuti chitsime chizidzipatula.

Mtundu wa msonkhano wa Locator umalola kusuntha kwa chisindikizo panthawi yopanga ndi kuchiza. Mtundu wa Anchor Assembly umasunga zisindikizo mkati mwa packer bore kuti aletse kuyenda kwa machubu.

Mayankho okhazikika a sealbore amapereka magwiridwe antchito abwino kuposa zida zomwe zitha kubwezedwa. Amakhala ndi zovuta zambiri pamapangidwe omwe amawapangitsa kukhala okwera mtengo.

Monga chimodzi mwa zida zofunika kwambiri pakumalizidwa, mapaketi ndi ovuta kwambiri kupanga mwaukadaulo. Mapaketi a Vigor amapangidwa pogwiritsa ntchito njira zotsimikizirika kwambiri ndipo nthawi zonse amayendetsedwa motsatira miyezo ya API11D1 panthawi yopanga. Ndi chifukwa cha kuwongolera mwamphamvu kwa Vigor panjirayo kuti mtundu wa malonda nthawi zonse umaposa zomwe kasitomala amayembekeza, ngati mukufuna chidwi ndi zida za Vigor zobowola ndikumaliza zida zodula mitengo, chonde musazengereze kulumikizana ndi gulu laukadaulo la Vigor kuti mupeze zabwino. zinthu zabwino ndi ntchito.
