Nigute wahitamo PDC bito?

1. Urutare rwa rock: Amarushanwa yo gukomera no guhinduka

Ikimenyetso Cyeri: Ubushobozi bw'urutare kugirango arengere deformation ya plastike cyangwa gushushanya.

INGORANE MU GIKURIKIRA (nka Granite, Basalt): Gukomera kwinshi Kugeza byoroshye gukata amenyo no kwambara bikabije bya drill bit. Ibiranga ibishushanyo bibereye bits:

Amenyo Yinshi Gukata amenyo: Ubwiza-bwohejuruPDC CutterHamwe n'ingaruka zikomeye zo kurwanya ingaruka kandi ituze ryiza ryumuriro rigomba gutoranywa.

Igishushanyo kinini: ongera imbaraga zumubiri wumuriro kugirango urwanye imbaraga zinyabutare.

Inguni ntoya: Inguni mbi yo guhagarika (nka -15 ° kugeza kuri -25 °

Igishushanyo mbonera cyo kurinda: kubuza Uwitekadrill bitDiameter kuva kugabanuka vuba kubera kwambara bikomeye.

2. Urutare rukurura: Ikigeragezo cyanyuma cyo kuramba

Ikimenyetso Cyeri: Ubushobozi bw'urutare kwambara amenyo yo gucamo nadrill bitumubiri (ufitanye isano rya hafi nibiri mumabuye y'agaciro akomeye nka Quartz).

Imiterere ya Abrasive cyane (nka Quartz Sandstone, granite yuzuye ubunini, ibice bya chert):

Ibirangaimyitozo:

Amenyo ya Ultra-wambara-Kurwanya Gutema: Koresha ibice bya PDC hamwe numutekano muremure

Ingamba zo Gutegura iryinyo ryuzuye: Ongera umubare wo gutema amenyo kugirango usangire umutwaro wambaye iryinyo rimwe.

Imiterere ya hydraulic yerekeranye: Guharanira Gukuraho Gukuraho Gukuramo kugirango wirinde kwambara byihuse kuberako yasya kabiri.

Ahantu hashimangiwe kurindwa / ahantu harwanya abrasion-irwanya ibinyabuzima: bigoye karbide cyangwa ibikoresho bya diyama mu rutugu no kurengera ibintu byo kurengera.

3. Imiterere yo gushinga hamwe nubusabane: guhuza n'imihindagurikire y'imikorere igoye

Ibitekerezo byibanze: Urwego rwo Gutezimbere Uburiri, ingingo, kuvunika muburyo bwa rutare, nibihe byo gusimburana ibintu bitoroshye kandi byoroshye.

Imiterere itoroshye (nk'ibirori byo kuvunika amakosa, shiti hamwe n'ingingo zanduye cyane, intanga ngabo-mudstone-mudstone):

Ibirangaimyitozo:

Kurwanya Ingaruka nyinshi: Gutema amenyo kandidrill bitUmubiri ugomba kuba ushobora kwihanganira ingaruka zingaruka ziterwa no guhinduka gutunguranye muri progaramu.

Igishushanyo gihamye: Imbaraga zingufu nziza (ihindagurika rito) hamwe nuburyo bwo kurinda umutekano kugirango wirinde kunyeganyega gukabije cyangwa gutandukana kwadrill bitmu turere dutongana cyangwa ibice byoroshye.

Imiterere yo gukata: irashobora kwemeza iryine ivanze cyangwa ibishushanyo mbonera byinyuma byo kuzamura imihindagurikire aho imiterere yububiko.

4. Gucukura ibipimo: icyiciro cyo gukora

Core ihuye: Igishushanyo cyadrill bitakeneye guhuza urwego ruteganijwe kuri gato (wob) hamwe numuvuduko wo kuzunguruka (RPM).

Ingingo z'ingenzi:

Wob yo hejuru / FPM nkeya: mubisanzwe ikwiriye gushiraho ibintu bikomeye, bisaba Uwitekadrill bitKugira imiterere ikomeye (nkibibyimba) hamwe n'amenyo mbi yo gutema amenyo.

Wob / FPM ndende: Ikwiriye yoroshye kubikorwa bisanzwe-bikomeye, thedrill bitIrashobora gukorerwa hamwe nigitambaro cyiza cyo gutema amenyo hamwe nuburyo bwa hydraulic bufasha gukuramo chip.

Ibipimo byerekana: Nubwo drill ubwayo ubwayo ikwiriye gushiraho urutare, ibipimo bidafite ishingiro (nko kwimura bidafite ishingiro bigamije kwikuramo kwikuramo) bizatera imbogamizi imbohe cyangwa imikorere mito.

5. Ubwoko bwa PDC Drill Bit: Buri kimwe gifite umwihariko

Ibyiciro byingenzi: Ukurikije intego zishushanyije hamwe na pronarios zisaba, hariho ubwoko bwingenzi bwaPdc yoroheje:

Ubwoko busanzwe: Bitandukanye, bikwiranye no kwicisha bugufi-byoroshye-bigoye, bitangaje.

Ubwoko / Ubwoko-bwo Kwihanganira Ingaruka: Imiterere ishingiye ku gahato (nk'icyuma cyabyibushye, cyazamuye uburinzi bworoshye, Amenyo Yihanganira Ingaruka), yagenewe bidasanzwe

Ubwoko burwanya cyane: Ukoresheje ibikoresho birwanya cyane, gahunda nziza kandi kandi ishimangira kurengera, ibangamira ahantu hashobora kugaragara (nka Quartz Sandstone.

Byimbitse / Ultra-Byimbitse Ubwoko: Gushimangira bidasanzwe kumuhanda wubushyuhe no kwizerwa mubushyuhe bwinshi hamwe nibidukikije.

Icyerekezo / Horizontal Ubwoko Bwihariye: Byongeshejwe Ubuyobozi, Guhagarara no Kurwanya Ubushobozi.

Umwanzuro: Gufata ibyemezo byinshi-Gufata neza bihuye neza
