Kusiyana Pakati pa Cement Retainers ndi Bridge Plugs

Kuchita Bwino Kwambiri Kubowola & Kugaya:

Ngati vuto ndi kuchita kubowola kapenantchito za mphero(mphero), machitidwe omwe akulimbikitsidwa ndi awa:

• Gwiritsani ntchito atricone pang'ono(IADC Bit Code2-1, 2-2, 2-3, 2-4, ndi 3-1) - mapangidwe olimba apakati.Chithunzi cha PDCsichikondedwa.
• RPM yabwino kwambiri idzakhala - 70 mpaka 125
• Gwiritsani ntchito kukhuthala kwamatope kwa 60 CPS pochotsa zodula
• Kulemera pang'ono - Ikani 5-7 Klbs. Mpaka kumapeto kwa pamwamba pa mandrel amabowoleredwa, omwe ndi mainchesi 4-5. Kenako onjezerani 3 Klbs. kulemera kwa inchi imodzi ya kukula pang'ono kubowola gawo lotsala. Chitsanzo: 4-1/2 pang'ono idzagwiritsa ntchito 9,000-13,500 lbs. za kulemera.
• Osagwiritsa ntchito kulemera kwake kuposa kuchuluka kovomerezeka. Kulemera kosaneneka kumatha kung'amba zigawo za Bridge Plug, ndipo kuyenda ulendo wina kudzakhala kovomerezeka kuchotsa ma chunks kuti alole kulowanso.
• Drill Collars- zidzagwiritsidwa ntchitoperekani WOB yofunikirandiKubowola pang'onoChitsanzo: 4-1/2 thru 5-1/2 (8 min.) 7 ndi kukulirapo (12 min.).
• Mabasiketi Azakudya-Basiketi imodzi kapena zingapo zotayira zidzagwiritsidwa ntchitokubowola chingwe. Ngati kusinthidwa kosinthira kukukonzekera, zida zilizonse mu chubu kapena chingwe chobowola ziyenera kukhala ndi ID yofananira ya bityo kuti zodula zisaduke.
• Annular Velocity- 120 ft / min iyenera kuganiziridwa.
• Zinyalala dengu pamwamba pang'ono.

Zida Zofunika Pokhazikitsa ndi Kutumikira

• Wireline Adapter Kit
• Stinger Seal Assembly
• Tubing Centralizer
• Chida Chokhazikitsa Makina
• Wireline Adapter Kit ya Flapper Pansi
• Chida cha Hydraulic Setting

Kukhazikitsa Pulagi ya Bridge & Njira Zotulutsa

Zowonadi, makhazikitsidwe ndi njira zotulutsira zizikhala zosiyana kuchokera kwa wopanga ndi wopanga. Koma, tikukudziwitsani njira wamba kuti mupeze lingaliro.

Tension Seti

Thamangani mpaka pakuya kofunikira kwinaku mwakhomerera ku chida chake chopezera.

Nyamulani, tembenuzani XX (1/4) tembenukira kumanja pa pulagi, ndikutsitsa chubu kuti mukhazikitse zoterera.

Kokani kukanikiza kokwanira pakulongedza zinthu, chepetsani, ndikunyamulanso kuti mutsimikizire kukhazikitsidwa kwa pulagi (15,000 mpaka 20,000 lbs).

Mukatha kuyimitsa pulagi, chepetsani kulemera kwa chubu, gwirani torque yakumanzere, ndikunyamula kuti mutulutse chida chothamangitsira pulagi.

Compression Set

Thamangani mpaka pakuya kofunikira kwinaku mwakhomerera ku chida chopezera.

Nyamulani, tembenuzani XX (1/4) tembenukira kumanja pa pulagi, ndikutsitsa chubu kuti mukhazikitse zoterera.

Chepetsani kulemera kokwanira pakulongedza zinthu, kenaka ikani kuti mukhazikitse zotsalira zam'mwamba ndikuchepetsanso (15,000-20,000 lbs).

Mukatha kuyimitsa pulagi, chepetsani kulemera kwa chubu, gwirani torque yakumanzere, ndikunyamula kuti mutulutse chida chothamangitsira pulagi.

Njira Yotulutsira

M'munsi machubu mpaka chopezera chida tagi pa pulagi mlatho ndi latches yomweyo.

Zungulirani kuti muchotse mchenga pazilipi za pulagi.

Tsegulani valavu yodutsa pochepetsa kulemera kwake, gwirani torque yakumanja, kenako nyamulani.

Yembekezerani kuti mufanane ndi kuthamanga.

Kokani m'mwamba kuti mutulutse zotsalira, kupumulani zinthu zolongedza, ndikumanganso.

Pulagi tsopano ikhoza kusuntha.

Ngati pulagi silingatuluke mwachizolowezi, chepetsani, yikaninso, kenako kukoka kuti mumete ma J-pini ndikumasula pulagi (mapini a J adzameta 40,000 mpaka 60,000 lbs iliyonse).

Mukatha kumeta mapini, chidacho sichidzatha kusunthira pansi.

Zofunika Zofunikira Pa Pulagi Ya Bridge Kuti Muganizirepo

Mapulagi ambiri a mlatho amabwera ndi njira yayikulu yolowera mkati kuti muchepetse kusuntha kwa RIH & POOH. Njira yodutsayi imatsegulidwa musanatulutse pulagi kuti mupange kufananiza kofanana. Ma BP ena amakhalanso ndi kuthekera kokhazikitsa ndi kunyamula chinthucho pamavuto.

Kubowoleza kwa chida kuyeneranso kuganiziridwa kuti kupulumutsa nthawi ndi mtengo wa ntchito.

Zida zina zimabwera ndi mawonekedwe osinthira kukhala chosungira simenti kapena kuchoka pamakina kupita ku seti yamawaya.

Chilolezo chabwino pakati pa pulagi ya mlatho ndi casing chiyenera kuganiziridwanso kuti chikhale ndi ntchito zothamanga komanso zotetezeka popanda kukhazikitsidwa mwadzidzidzi.

Pali mapangidwe ena omwe amalepheretsa kuyenda chifukwa cha zopinga zotsutsana. Izi zimatsimikizira kuti sipadzakhala kusuntha ngati kupanikizika kwapadera kukukwera ndi njira (mmwamba kapena pansi).

Mapulagi a mlatho ndi zida zofunika zotsika pansi zomwe zimagwiritsidwa ntchito popanga mafuta ndi gasi pakufanana kwa mphamvu, kusiyidwa kwakanthawi, komanso kudzipatula kwa zonal. Pali mitundu ingapo ya mapulagi a mlatho omwe amapezeka kuti agwirizane ndi ntchito zosiyanasiyana. Mtundu uliwonse uli ndi mawonekedwe ake apadera komanso zopindulitsa zomwe zimapangitsa kuti zikhale zoyenera kwa mitundu ina ya ntchito. Kugwiritsa ntchito mtundu woyenera wa pulagi ya mlatho kumatha kuchepetsa kwambiri nthawi ndikuwonetsetsa kuyesedwa kopambana.

Ngati muli ndi chidwi ndi zida za pulagi ya Vigor's bridge, chonde musazengereze kulumikizana nafe kuti mupeze zinthu zaluso kwambiri komanso ntchito yabwino kwambiri.
