05 Kupulumutsa ku Downhole
1. Chabwino kugwa mtundu
Malingana ndi dzina ndi chikhalidwe cha zinthu zomwe zikugwa, mitundu ya zinthu zomwe zikugwera m'zitsime makamaka zimaphatikizapo: zinthu zogwa chitoliro, zinthu zogwa pamtengo, zingwe zogwa ndi tizidutswa tating'ono tating'ono ta zinthu zogwa.
2. Kupulumutsidwa kwa zinthu zomwe zagwa chitoliro
Asanayambe kusodza, munthu ayenera kumvetsetsa zoyamba za zitsime za mafuta ndi madzi, ndiko kuti, kumvetsetsa zobowola ndi kupanga mafuta, kudziwa momwe chitsimecho chilili, momwe kanyumba kameneka, komanso ngati pali zinthu zoyamba kugwa. Kachiwiri, fufuzani chifukwa cha zinthu zomwe zikugwa, ngati pali mapindikidwe ndi mchenga pamwamba pa maliro pambuyo zinthu kugwa kugwa mu chitsime. Werengetsani kuchuluka komwe kungapezeke mukawedza, limbitsani dzenje la derrick ndi guyline. Ziyeneranso kuganiziridwa kuti mutatha kugwira zinthu zomwe zagwa, payenera kukhala njira zodzitetezera komanso zotsutsana ndi jamming ngati mukugwedeza mobisa.
Zida zopha nsomba zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo ma cones achikazi, ma cones aamuna, mikondo yopha nsomba, migolo yophera nsomba, etc.
Njira zopulumutsira ndi:
(1) Tsitsani nkhungu yotsogolera yoyendera mobisa kuti mumvetsetse malo ndi mawonekedwe a zinthu zomwe zikugwa.
(2) Malingana ndi zinthu zomwe zikugwa ndi kukula kwa malo a annular pakati pa zinthu zomwe zikugwa ndi casing, sankhani zida zoyenera zophera nsomba kapena kupanga ndi kupanga zida zopha nsomba nokha.
(3) Lembani kamangidwe ka zomangamanga ndi njira zotetezera, ndikuchita chithandizo cha salvage molingana ndi kamangidwe kamangidwe pambuyo povomerezedwa ndi madipatimenti oyenera malinga ndi ndondomeko yoperekera malipoti, ndikujambula zithunzi za zida zolowera m'chitsime.
(4)Opaleshoniyo ikhale yokhazikika posodza.
(5)Unikani zinthu zomwe zagwa zomwe zapulumutsidwa ndi kulemba chidule.
3. Usodzi wothira pamtengo
Zambiri mwa zinthu zomwe zikugwa zimakhala zoyamwitsa, komanso pali ndodo ndi zida zolemetsa. Zinthu zogwa zimagwera m'bokosi ndikugwera m'chitoliro chamafuta.
(1) Kupha nsomba m’chubu
Ndikosavuta kupulumutsa ndodo yosweka mu chubu. Mwachitsanzo, ndodo yoyamwa ikagundidwa, ndodoyo imatha kutsitsidwa kuti igwire kapena kutsitsa chidebecho kuti chipulumuke.
(2) Kupha nsomba m’khola
Kusodza mu casing kumakhala kovuta kwambiri, chifukwa mkati mwake mkati mwa casing ndi lalikulu, ndodo ndi zowonda, chitsulo ndi chaching'ono, chosavuta kupindika, chosavuta kutulutsa, ndipo mawonekedwe a chitsime chakugwa ndi ovuta. Populumutsa, ikhoza kupulumutsidwa ndi mbedza kuti iwongolere kutsetsereka kwa nsapato kapena kuwombera masamba. Chinthu chogwacho chikapindika m'bokosi, chimatha kupulumutsidwa ndi mbedza. Zinthu zogwa zikamangika mobisa ndipo sizingaphatikizidwe, gwiritsani ntchito silinda ya mphero kapena nsapato ya mphero popera, ndipo gwiritsani ntchito maginito usodzi kupha zinyalala.
4. Kupulumutsa zinthu zazing'ono
Pali mitundu yambiri ya zinthu zing'onozing'ono zogwa, monga mipira yachitsulo, nsagwada, mawilo a gear, zomangira, ndi zina zotero. Ngakhale kuti zinthu zomwe zimagwa zimakhala zazing'ono, zimakhala zovuta kwambiri kuzipulumutsa. Zida zopulumutsira zinthu zing'onozing'ono ndi zakugwa makamaka zimaphatikizapo kupulumutsa maginito, kulanda, dengu la reverse circulation salvage ndi zina zotero.
