Imiterere itandukanye ya PDC

Gucukura nigikorwa cyingenzi mubikorwa bya peteroli na gaze. Bits ya PDC (nanone yitwa Polycrystalline Diamond Compact bit) ikoreshwa mugikorwa cyo gucukura. PDC bit ni ubwoko bwa biti bigizwe na polycrystalline Diamond nyinshi (PCD) ifatanye kumubiri wa biti hanyuma igacibwa mumabuye mugukata ibikorwa hagati yabatemye nigitare.

Gukata PDC nigice cyingenzi cyimyitozo ya bito, nayo ifarashi yo gukoreramo. Imiterere itandukanye ya PDC igabanya intego zakazi zitandukanye. Guhitamo imiterere iboneye ni ngombwa cyane, bishobora kunoza imikorere yawe no kugabanya ikiguzi.

Mubisanzwe, tugabanije gukata PDC nkuko bikurikira:

1． Amashanyarazi ya PDC

2． Utubuto twa PDC

Amashanyarazi ya PDC akoreshwa cyane cyane mu gucukura ibice byo gucukura no gucukura peteroli. Irashobora kandi gukoreshwa muri diyama ya biti na PDC.

Ibyiza byingenzi kubatema PDC:

• Ubucucike bukabije (porosity)

• Guhuza byinshi hamwe no guhuza ibitsina

• Kwambara cyane no kurwanya ingaruka

• Ubushyuhe bwo hejuru cyane

• Imikorere myiza muri rusange iboneka ku isoko

PDC yamashanyarazi ya diametre kuva kuri 8 kugeza 19mm ::

Ibisobanuro byavuzwe haruguru ni kubakoresha guhitamo. Mugihe kimwe, ibisobanuro bitandukanye byibicuruzwa birashobora kubyara no gutunganywa ukurikije ibisabwa nabakoresha.

Nkibisanzwe, ibinini binini (19mm kugeza 25mm) birakaze kuruta uduce duto. Ariko, barashobora kongera ihindagurika ryumuriro.

Imashini ntoya (8mm, 10mm, 13mm na 16mm) yerekanwe gucukura ku kigero cyo hejuru cyo kwinjira (ROP) kuruta gukata binini mubisabwa bimwe. Imwe muriyo porogaramu ni hekeste kurugero. Bits zashizweho hamwe nuduce duto ariko byinshi muribyo birashobora kwihanganira ingaruka ziremereye.

Byongeye kandi, uduce duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto duto. Ibiti binini bishobora gutera ibibazo byo gusukura umwobo niba amazi yo gucukura adashobora gutwara ibiti hejuru.

Kubyara PDC

Imashini ya PDC ikoreshwa nka antifriction itwara moteri yo hasi, ikoreshwa cyane mumasosiyete akorera peteroli hamwe ninganda za moteri zimanuka. Ububiko bwa PDC bufite ubwoko butandukanye burimo PDC ya radiyo, ibyuma bya PDC.

Imyenda ya PDC irwanya cyane kwambara. Ugereranije na karubide ya tungsten gakondo cyangwa izindi zikomeye zivanze, ubuzima bwa diyama buba inshuro 4 kugeza 10, kandi burashobora gukora mubushyuhe bwinshi (kuri ubu ubushyuhe bwo hejuru ni 233 ° C). Sisitemu yo gutwara PDC irashobora gukuramo umutwaro urenze igihe kinini, kandi igihombo gito cyo guterana mukiterane cyongera imbaraga za mashini zoherejwe.

Utubuto twa PDC dukoreshwa cyane cyane kuri DTH drill bit, cone bit, na diamant.

Amabuye ya diyama akoreshwa cyane cyane mumashini acukura amabuye y'agaciro, nk'ingoma zikomeza gucukura amabuye y'agaciro, ingoma zogosha za Longwall, imashini irambirana ya tunnel (imashini yimashini ikingira, imashini izunguruka, kuzunguruka, kuvuza ingoma, n'ibindi)

Utubuto twa PDC harimo:

(1) PDC ya buto ya PDC: ikoreshwa cyane kuri DTH drill bit.

(2) Utubuto twa PDC: cyane cyane ikoreshwa kuri biti.

(3) Utubuto twa parabolike ya PDC: ikoreshwa cyane mugukata infashanyo.

Ugereranije na tungsten ya karbide ya buto, buto ya PDC irashobora kunoza imiti irwanya inshuro 10.

Usibye ubunini busanzwe, turashobora kandi kubyara umusaruro ushushanyije.

Murakaza neza kugirango ubone zzbetter PDC ikata, imikorere myiza, ubuziranenge buhoraho, nagaciro keza.
