Ni bangahe uzi kubyerekeye gukata PDC?

Ibyerekeye PDC (Polycrystalline Diamond Compact) Cutter

PDC (Polycrystalline Diamond Compact) Cutter ni ubwoko bwa superhardibikoresho bigabanya diyama ya polycrystalline hamwe na karubide ya tungsten yubushyuhe bukabije nubushyuhe.

Ivumburwa ryumutemeri wa PDC ryateje imberebitikugeza imbere mubikorwa byo gucukura, kandi igitekerezo cyahise gikundwa. Kuva ikogoshaIgikorwa cyo gukata PDC ningirakamaro kuruta guhonyora ibikorwa bya buto cyangwa amenyo ya biti, gukata neza- bitzirakenewe cyane.

Mu 1982, imyitozo ya PDC yagizwe 2% gusa yibirenge byose byacukuwe. Muri 2010, 65% yubuso bwacukuwe bwakozwe na PDC.

Uburyo Cutters ya PDC ikorwa? 

PDC Cutters ikozwe muri tungsten karbide substrate na diyama ya gritike. Ikozwe hifashishijwe ubushyuhe bwubushyuhe hamwe numuvuduko mwinshi hamwe na catalizator ya cobalt alloy kugirango ifashe guhuza diyama na karbide mugihe cyo gucumura. Mugihe cyo gukonjesha, karbide ya tungsten igabanuka ku kigero cyikubye inshuro 2,5 kurenza diyama, ihuza Diamond na Tungsten Carbide hamwe hanyuma igakora Cutter ya PDC.

Ibiranga na Porogaramu

Kubera ko PDC Cutters igizwe na diyama grit na tungsten karbide substrate, ihuza ibyiza bya diyama na karubide ya tungsten.： 

1. High abrasion irwanya

2. High ingaruka zirwanya

3. High

Ubu PDC Cutters ikoreshwa cyane mubucukuzi bwa peteroli, gaze nubushakashatsi bwa geologiya, gucukura amakara, hamwe nibindi byinshi byo gucukura no gusya, ibikoresho nka PDC Drill Bits, nka Steel PDC Drill Bits & Matrix PDC Bits yo gucukura peteroli na Tri-cone PDC Imyitozo yo gucukura amakara.

Imipaka

Ingaruka zangirika, kwangirika kwubushyuhe, hamwe no kwambara byangiza byose bibuza gukora imyitozo ya bito kandi birashobora kugaragara no muburyo bworoshye bwa geologiya. Ariko, ibintu bigoye cyane kuri PDC bitobora biratangaje cyane.

Kinini VS ntoya

Nkibisanzwe, ibinini binini (19mm kugeza 25mm) birakaze kuruta uduce duto. Ariko, barashobora kongera ihindagurika ryumuriro. Byongeye kandi, niba BHA itarakozwe kugirango ikemure ubukana bwiyongereye, ihungabana rishobora kuvamo.

Imashini ntoya (8mm, 10mm, 13mm, na 16mm) yerekanwe gucukura kuri ROP ihanitse kuruta ibinini binini mubisabwa. Imwe muriyo porogaramu ni hekeste.
Na none, bits zashizweho hamwe nuduce duto ariko byinshi muribyo birashobora kwihanganira ingaruka zikomeye imizigo. 

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 birashobora gutera ibibazo mugusukura umwobo niba amazi yo gucukura adashobora gutwara ibiti hejuru ya annulus.

imiterere

Imiterere ya PDC ikunze kugaragara cyane ni silinderi, igice kubera ko amashanyarazi ya silindrike ashobora gutondekwa muburyo bworoshye muguhagarika umwirondoro wa biti kugirango ugere kubucucike bunini. Imashini zisohora ibyuma bya elegitoronike zirashobora gukata neza no gushushanya ameza ya diyama ya PDC. Imigaragarire idahwitse hagati yameza ya diyama na substrate igabanya imihangayiko isigaye. Ibi biranga kunoza uburyo bwo gukata, gutemba, no kumeza ya diyama. Ibindi bice bishushanya bigabanya imbaraga zo kurwanya kugabanya urugero rwibibazo bisigaye.
