"Umutima" wa Tricone Roller Bits: Ubwoko butatu bwo gutwara ibintu bugena neza gucukura

Mubushakashatsi bwa peteroli na gaze hamwe nubucukuzi bwa geologiya ,.roller cone bitni nk "inyamaswa yicyuma" yinjira mu butaka, kandi kubyara bikora nk "umutima" wiyi nyamaswa. Ifasha umuvuduko mwinshi wo kuzenguruka ya roller, kwihanganira imikazo yo munsi yubutaka no guterana amagambo, kandi igena neza ubuzima bwa serivisi ya biti nuburyo bwiza bwo gucukura. Uyu munsi, tuzasenya ubwoko butatu bwibanze bwubwoko bwa roller cone bits, dusuzume amabanga ya tekinike inyuma ya buri kintu na ssenariyo aho bitwaye neza.

I. Kunyeganyeza Rubber Ifunze: Igiciro-Cyiza Nyampinga, Umufasha Wizewe Kubintu Byoroheje kugeza Hagati-Bikomeye

Mubihe bisanzwe byo gucukura, kunyerera bifunze reberi ni "inararibonye" ifite uburambe bwo gukoresha. Imiterere yacyo ntabwo igoye; intangiriro igizwe nigitambambuga cyo kunyerera kigizwe nikinyamakuru kivanze nicyuma cyihanganira kwambara. Nkibice bibiri byuma byuzuye neza, byohereza imbaraga binyuze mukunyerera. Kugirango wirinde kwinjiza amazi yo gucukura, inteko yabugenewe yo gufunga kashe—nka kashe ya radiyo impeta na gasketi zanyuma—yashyizwe kuruhande rwinyuma rwikizenga, kandi urwobo rwuzuyemo amavuta menshi-yuzuye kugirango bibe "inzitizi yo gukingira."

Ibyiza byingenzi byiyi myitwarire biri muri "stabilite" no "gukora neza." Igishushanyo mbonera cyerekana uburyo bwo gukwirakwiza imitwaro hamwe no guhangana ningaruka zisumba izindi, bikemerera gukora neza nubwo haba harumuvuduko mwinshi wo gucukura no kwihuta cyane. Byongeye kandi, irerekana ibiciro byo gukora no kubungabunga byoroshye—nyuma yo kwambara, gusa bushing igomba gusimburwa kugirango igarure biti kuri serivisi. Ariko, kashe ya reberi ni "intege nke" zayo: ubusanzwe ubushyuhe bwayo ntiburenga 120°C.

Kubwibyo, "urugamba nyamukuru" rwo kunyerera rwa reberi rufunze ruri mu buryo bworoshye kandi buciriritse, nk'ibumba, umusenyi, n'amabuye. Birakwiriye cyane cyane kubutaka busanzwe bwo gucukura,gucukura icyerekezo, kandi idakora neza ibikorwa aho kugenzura ibiciro ari ngombwa. Niba ibyifuzo byawe byo gucukura bihuye nibi bintu, iyi myitozo izaba ihitamo cyane.

II. Kuzunguza Rubber Ifunze: Igikoresho Cyiza Cyambere Pioneer, Igikoresho Cyibanze Hagati-Ikomeye Kuri Imiterere

Iyo gucukura bihindutse hagati-bigoye-bigoye cyane, nka granite na basalt, imikorere yo kunyerera ifunze reberi iba idahagije—kandi ni mugihe kizunguruka gifunze reberi ifata icyiciro. Iterambere ryibanze ni ugusimbuza gakondo kunyerera hamwe nibintu bizunguruka (imipira cyangwa imipira). Byombi kuzunguruka hamwe nimpeta y'imbere / hanze bikozwe muburyo buhanitse bwo kwambara budashobora kwangirika, mugihe hagumishijwe kashe ya reberi hamwe na sisitemu yo gufunga no gusiga amavuta.

Impinduka zikomeye zizanwa no guterana amagambo ni "kugabanya imbaraga": kurwanya ubukana biragabanuka cyane,bitgutangira torque ni nto, kandi irashobora kugera byoroshye umuvuduko wo kuzunguruka. Umuvuduko wo gucukura imashini wiyongera 10% -30%, nta gushidikanya ko aribyiza byingenzi mumishinga ikurikirana gucukura neza. Ariko, iragwa kandi imipaka ya kashe ya rubber—ubushyuhe bwacyo ntarengwa bwo hejuru burenze gato ubw'inyerera, ariko bugera kuri 130 gusa°C, hamwe ningutu yumuvuduko wa 60MPa. Ikigeretse kuri ibyo, ibintu bizunguruka byumva cyane umwanda; ibice bikomeye mumazi yo gucukura birashobora gutera byoroshye guhuzagurika, kubwibyo bisabwa cyane bishyirwa ku isuku yamazi yo gucukura.

Hashingiwe kuri ibyo biranga, ibyuma bifunga reberi bifunze cyane cyane mu gucukura mu bucukumbuzi bukomeye kandi bukomeye, nk'ibice bihagaritse by'iriba ryimbitse kandi rinini cyane, ndetse n'imishinga yo gucukura ikora neza isaba umuvuduko wo gucukura cyane. Kubijyanye no gutoranya amazi yo gutobora, birahujwe cyane namazi meza hamwe na sisitemu yo gucukura ibice-bikomeye. Kugirango utange umukino wuzuye kubyiza-bikora neza, gukoresha amazi yo gucukura arimo ibice binini bikomeye bigomba kwirindwa bishoboka.

III. Ikizunguruka kidafunze Ikirere: Impuguke yo hejuru yubushyuhe bwo hejuru, Impuguke yihariye yuburyo budasanzwe bwo gucukura

Mu bushyuhe bwo hejuru cyane hamwe n’umuvuduko ukabije w’ubucukuzi bwimbitse, nk'iriba rya geothermal hamwe na gaz ya shale iriba ryimbitse, kashe ya reberi yubwoko bubiri bwa mbere izananirana kubera ubushyuhe bwinshi. Kuri iyi ngingo, umwuka wikizunguruka udafunze uhinduka igisubizo cyonyine gifatika. Igishushanyo mbonera cyacyo ntigisanzwe: ifata ibintu byuzuzanya ariko ikuraho burundu inteko. Umuyoboro woguhuza uhujwe neza nuburyo bwo gucukura, kandi umwuka wumuvuduko mwinshi cyangwa amazi ya atome atobora akoreshwa nkuburyo bwo gukonjesha no gusiga amavuta.

Hatabayeho imbogamizi za kashe, kurwanya ubushyuhe bwayo byageze ku gusimbuka neza, bigera kuri 200°C, ishoboye rwose guhuza nubushyuhe bwo hejuru cyane munsi yubutaka. Muri icyo gihe, umwuka w’umuvuduko ukabije uhora usukura urwungano ngogozi, ntirukuraho gusa ubushyuhe buterwa no guterana amagambo ahubwo runirukana neza ibice byinjira kugirango wirinde kwambara, bizamura cyane kwizerwa mubidukikije. Ariko, ifite kandi "ibisabwa" byihariye: ifite ibyifuzo byinshi cyane kuri sisitemu yo gutanga ikirere, bisaba isoko yumuyaga mwinshi uhoraho. Byongeye kandi, ubuzima bwo kubyara bugira ingaruka ku isuku y’isoko ry’ikirere—niba umwanda uvanze mumasoko yikirere, birashobora guteza ibyangiritse byoroshye.

Ubu bwoko bwo gutwara ibintu bufite ubuhanga bwihariye, bukoreshwa cyane cyane mubushyuhe bukabije nubushyuhe bwo hejuru cyane, ndetse nuburyo budasanzwe nko gucukura nabi hamwe no gucukura ikirere. Muri ubu buryo, umwuka wumuvuduko mwinshi ntabwo utanga amavuta gusa nogukonjesha kubyara gusa ahubwo unarinda neza gusenyuka neza, kugera kuntego ebyiri icyarimwe. Twabibutsa ariko ko bidahuye rwose na sisitemu isanzwe y’amazi ashingiye ku mazi kandi ishobora gukorera gusa muri gaze cyangwa itangazamakuru ryamazi atobora—iyi niyo ntandaro yo gusaba kugarukira.

Incamake: Nigute ushobora guhitamo mubintu bitatu? Guhuza Ibikorwa Byakazi Nibyingenzi

Nyuma yo kwiga ibisobanuro birambuye kuri ibi bitatu, biragaragara ko nta busumbane bwuzuye cyangwa ubudashyikirwa muri bo—gusa itandukaniro rihuye nibikorwa byihariye byakazi. Mumagambo yoroshye, logique yibanze yo gutoranya irashobora kuvunagurwa mubice bitatu:

Kubintu byoroheje kugeza hagati-bigoye kandi bitameze neza aho ibikorwa-byibanze byambere, hitamo kunyerera bifunze reberi; kubiciriritse-bigoye kugeza aho bigoye gusabwa umuvuduko mwinshi kandi neza, hitamo ibizunguruka bifunze; naho kuri ultra-high ubushyuhe, ultra-high pressure iriba ryimbitse cyangwa inzira zidasanzwe nko gucukura ikirere, gutwara ikirere kidafunze nikintu cyonyine.

Nka "mutima" wa roller cone bit, guhitamo gutora bigira ingaruka itaziguye kubiciro, imikorere, numutekano wibikorwa byo gucukura. Twizera ko iyi ngingo izagufasha gusobanura itandukaniro ryibanze hagati yibi bintu bitatu, bikagufasha guhitamo "umutima" ukwiye kubikorwa bifatika byo gucukura no kwemeza gucukura neza kandi byizewe igihe cyose.
