Ubuvuzi bwa cryogenic bwo gukata PDC

PDC ikata ni ibintu byinshi hamwe nibintu byiza byabonetse mugucumura ifu ya diyama hamwe na sima ya karbide ya sima ikoresheje ubushyuhe bwinshi hamwe nikoranabuhanga ryinshi (HTHP).

Gukata PDC bifite ubushyuhe bukomeye bwumuriro, gukomera cyane, no kwambara birwanya imbaraga, hamwe nimbaraga nyinshi, gukomera gukomeye, kandi byoroshye gusudira.

Igice cya diyama ya polycrystalline gishyigikirwa na sima ya karbide ya sima, ishobora gukuramo ingaruka nini kandi ikirinda kwangirika gukomeye mugihe cyakazi. Niyo mpamvu, PDC yakoreshejwe cyane mugukora ibikoresho byo gutema, geologiya na peteroli na gaze ya dring bits, nibindi bikoresho birwanya kwambara.

Mu murima wa peteroli na gaze, ibice birenga 90% byamashusho yose yo gucukura byujujwe na PDC bits. PDC bits isanzwe ikoreshwa mugucukura urutare rworoshye. Ku bijyanye no gucukura byimbitse, haracyari ibibazo byubuzima buke na ROP yo hasi.

Muburyo bwimbitse bugaragara, imiterere yakazi ya PDC drill bit irakaze cyane. Uburyo nyamukuru bwo kunanirwa igice cyibice birimo macro-kuvunika nk amenyo yamenetse no gukata byatewe ningaruka zatewe na biti ya myitozo yakira umutwaro munini, hamwe nubushyuhe bukabije bwo hasi butera ibice. Kugabanuka kwimyambarire yurupapuro bitera kwambara ubushyuhe bwurupapuro rwa PDC. Kunanirwa kuvugwa hejuru kurupapuro rwa PDC bizagira ingaruka cyane kubuzima bwa serivisi no gukora neza.

Ubuvuzi bwa Cryogenic ni ubuhe?

Kuvura Cryogenic ni kwagura ubushyuhe busanzwe. Ikoresha azote yuzuye hamwe na firigo nkibikoresho bikonjesha kugirango bikonje ibikoresho kugeza ku bushyuhe buri munsi yubushyuhe bwicyumba (-100 ~ -196 ° C) kugirango bongere imikorere yabo.

Ubushakashatsi bwinshi buriho bwerekanye ko kuvura cryogenic bishobora guteza imbere cyane imiterere yubukorikori bwibyuma, aluminiyumu, nibindi bikoresho. Nyuma yo kuvura cryogenic, ibintu bikomeza imvura bibaho muribi bikoresho. Ubuvuzi bwa kirogenike burashobora kunoza imbaraga zidasanzwe, kwambara, no kugabanya imikorere yibikoresho bya karbide ya sima, biherekejwe no kuzamura ubuzima. Ubushakashatsi bujyanye nabwo bwerekanye ko kuvura cryogenic bishobora guteza imbere imbaraga zo guhagarika imbaraga za diyama, impamvu nyamukuru yo kongera imbaraga ni uguhindura imitekerereze isigaye.

Ariko, turashobora kunoza imikorere ya PDC ikata binyuze mumiti ya cryogenic? Kuri ubu hari ubushakashatsi buke bufite akamaro.

Uburyo bwo kuvura cryogenic

Uburyo bwo kuvura cryogenic kubatema PDC, ibikorwa ni:

(1) Shira ibyuma bya PDC mubushyuhe bwicyumba mu itanura ryo kuvura;

. iyo ubushyuhe bugeze -30 ℃, bizagabanuka kugeza kuri -1 ℃ / min. Mugabanye -120 ℃; ubushyuhe bumaze kugera kuri -120 ℃, gabanya ubushyuhe kuri -196 ℃ ku muvuduko wa -0.1 ℃ / min;

(3) Bika amasaha 24 ku bushyuhe bwa -196 ° C;

. ya 3 ° C / min;

.

Ikariso ya PDC ivura hamwe na PDC itavuwe yageragejwe kugirango igereranwe ryimyambarire. Ibisubizo by'ibizamini byagaragaje ko ibipimo byo kwambara byari 3380000 na 4800000. Ibisubizo by'ibizamini byerekanye ko nyuma yo gukonja cyane Ikigereranyo cyo kwambara cya PDC ivura ubukonje kiri hasi cyane ugereranije n’icyuma cya PDC kitavuwe.

Byongeye kandi, amashuka ya PDC yatunganijwe kandi atavuwe yarasuditswe kuri matrix hanyuma acukurwa kuri 200m mugice kimwe cyamariba yegeranye afite ibipimo bimwe byo gucukura. Gukora imashini ya ROP ya biti ya drill yiyongereyeho 27.8% ukoresheje PDC ivura korogeje ugereranije nudakoresha kode ya PDC ivura.

Uratekereza iki kubijyanye no kuvura cryogenic yo gukata PDC? Murakaza neza kugirango mudusigire ibitekerezo byanyu.
