Ni irihe tandukaniro riri hagati y'umubiri w'icyuma n'umubiri wa matrix PDC bit?

Igicucu cya PDC gikorwa ahanini n'ibyuma bya PDC bicukura n'ibyuma, bihuza ubukana bwiza bw'icyuma no kudashira kw'icyuma cya polycrystalline diamond compact bituma igicucu cya PDC kigira uburebure bwihuse mu gikorwa cyo gucukura. Igicucu cya PDC gifite umuvuduko wihuta mu gukora ibintu byoroshye mu gihe igicucu cya PDC gifite uburebure bw'igicucu cya PDC kirwanya kwangirika, igicucu cya matrix gishobora gucukura bikomeye ugereranije n'igicucu cya PDC bitewe n'umubiri wacyo wa tungsten carbide matrix, ariko gifite uburebure buto ugereranije n'igicucu cya PDC. Niba ushishikajwe n'igice cya PDC, ndakwinginze hamagara Far Eastern Drilling.

Uduce twa PDC tw'umubiri wa Matrix ugereranije n'uduce twa PDC tw'umubiri w'icyuma

Niba umaze igihe runaka ukora mu gucukura, ushobora kuba warumvise ibyerekeye uduce twa PDC. PDC isobanura "polycrystalline diamond compact," bisobanura imvange y'ibikoresho bigize ubuso bw'utu duce. Matrix Body PDC na Steel Body PDC byombi bikorwa muri iyi mvange.

Utu duce dufite amazina menshi. Bakunze kwitwa:

• Uduce twa PDC
• Uduce duto twa diyama ya polycrystalline
• Uduce tw'amenyo y'ibice by'ibumba
• Uduce tw'uduce two gukata diyama twa polycrystalline

Uduce twa PDC dukunze gukoreshwa mu gucukura peteroli - ariko dukunzwe no mu zindi nganda. Twakozwe mu 1976 kandi ubu turakunzwe nk'ukouduce tw'udupira tw'amapine(ubwoko bw'igice gifite ibice bizenguruka). Nubwo ibice bya PDC bifite amateka maremare yo kugira icyo bigeraho, bikomeza gutera imbere no guhora bitera imbere binyuze mu nguni nshya kandi zigezweho zo guca, gutunganya, n'ibikoresho. Ibi bice birakora neza cyane kuko bikora mu gukata amabuye aho kuyasya. Buri mwaka, iterambere rishya mu ikoranabuhanga rirushaho kunoza imikorere y'ibice bya PDC no kunoza umuvuduko wo gucukura.

Utu duce tuzwi nk'uduce "tugera ku ibara" tw'inganda zicukura - dukora akazi kandi dushobora kugira akamaro kanini kuri serivisi zitandukanye n'ubwoko butandukanye bw'imashini - nta bice byimuka ngo bihure, nta mvururu, gucukura neza gusa ku byo ukeneye byose.

Uduce twa PDC ni iki?

Hari ubwoko bubiri bw'ibanze bwaUduce two gucukura twa PDC– uduce twa PDC tw’umubiri wa matrix n’uduce twa PDC tw’icyuma. Byombi bifite imiterere isa n’utundi duce dufite imiterere ine kugeza ku munani yo gukata, cyangwa ibyuma, biva hagati. Buri icyuma gishyirwa hejuru y’uduce turi hagati ya cumi na mirongo itatu. Utwo duce dufite imiyoboro y’amazi itatanye kugira ngo ikonje, kandi hari n’akantu ko ku mutwe w’agace. Niba ugerageza kwiyumvisha aka gace, kameze nk’ikamba umwami ashobora kwambara.

Uduce twa PDC dukoreshwa mu gucukura peteroli na gaze, gucukura ingufu z'amashanyarazi, gucukura amariba y'amazi, gucukura ubwubatsi, gucukura amabuye y'agaciro no gucukura mu cyerekezo kitambitse.

Ubumenyi bwihishe inyuma y'uduce twa PDC

Ushobora kuba warize mu ishuri ko diyama ari yo igoye cyane ku muntu. Ni yo! Kandi ni nziza cyane mu gukata ibindi bikoresho nk'amabuye yo gucukura.

Uduce twa PDC dukoresha diyama nto, zihendutse kandi zakozwe n'abantu mu buryo bwo gukata. Uburyo bwo gukora diyama kuri utwo duce buragoye. Byoroshye, dore uburyo bwo gukora utwuma twa diyama:

• Diyama ntoya zikozwe mu buryo bwa sintetike zikorwa
• Diyama zishyirwa hamwe mu matsinda manini y'amakristaro
• Hanyuma kristu zishushanywa mu mbonerahamwe za diyama
• Hanyuma ameza ya diyama afatwa ku cyuma, akenshi karubide ya tungsten, n'icyuma gifunga
• Iki kiba igice cyo gukata igice - hari utumashini twinshi two gukata kuri buri gice cy'igice
• Hanyuma ibyuma bishyirwa ku byuma, bifatanye n'umubiri w'igice

Hamwe, ibyuma byo gukata n'ibyuma biri ku mutwe w'igice cya PDC bikoreshwa mu gukata amabuye y'ubwoko bwose.

Diyama zikoze mu byuma bicukura

Nkuko mubibona, diyama zikoze mu buryo bwa sintetike ni ingenzi mu gukora uduce twa PDC. Mu gukora utu duce, hakorwa utubuto duto cyane twa diyama (tuzwi kandi nk'uduce twa diyama). Iyi grit iraramba cyane ariko ntihinduka ihamye ku rwego rwa molekile iyo ishyushye. Bityo, grit yawe ya PDC ishobora kwangirika niba idakonje neza iyo ikoreshejwe.

Uko byagenda kose, diyama zikoze mu nganda ntizipfa kwangirika cyane; ni zo zikwiriye kugira ngo zirambe kandi zirambe. Ubwoko bw'icyuma burahinduka iyo uhisemo matrix cyangwa icyuma gikozwe mu nganda - ariko diyama ni ingenzi cyane. Uduce twa PDC dushobora kumara igihe kirekire mu gihe dukonje neza.

Uduce twa PDC tw'umubiri wa Matrix
