Uru nke PDC ibe n'ibe

Polycrystalline diamond compact (PDC) na PDC drill bits ka ewebatala n'ahịa ruo ọtụtụ iri afọ. N'ime ogologo oge a,onye na-egbutu PDC na PDC drill bit enwetala ọtụtụ ihe ndọghachi azụ n'oge mmalite ha, nwetakwara nnukwu mmepe. Nwayọọ nwayọọ mana n'ikpeazụ, PDC ibe n'ibe ji nwayọọ nwayọọ dochie cone ibe n'ibe na-aga n'ihu na nkwalite na PDC cutter, bit kwụsie ike, na bit hydraulic Ọdịdị. Mpekere PDC na-eji ugbu a karịa 90% nke mkpokọta egwu egwu n'ụwa.

A na-eji ihe egwu egwu diamond na-eme ihe fọrọ nke nta ka ọ bụrụ ngwa niile gụnyere mgbawa ike geothermal, igwu ala, mmiri mmiri, mkpọpu ikuku gas, na igwu mmiri nke ọma.

Nke a bụ ụfọdụ uru nke bits PDC.

1. Ọnụ-dị irè

Mpekere PDC nwere ike ịdị oke ọnụ ahịa. N'adịghị katricone bit, ọ dịghị akụkụ na-akpụ akpụ na a PDC bit na-agwụ ike. Ola diamond sịntetịt chere ihu nwere ike ịgbawa, mana enwere ike ịwepụta ihe na-egbutu PDC ma tinye nke ọhụrụ n'ọnọdụ ya. Ịrụghachi ntakịrị PDC na-abụkarị ihe dịka ọkara ọnụahịa ịzụrụ ntakịrị ọhụrụ.

2. Ọnụ ọgụgụ nke penetration

PDC ibe n'ibe, n'ụdị ziri ezi, nwere ọnụ ọgụgụ dị egwu nke ntinye. Nhazi nke bits PDC na-eme nke ọma gụnyere mana ọnweghị oke na shale, limestone, nkume aja, na ụrọ. Iberibe PDC nwere ike ịbụ ebe ọ bụla ruo ugboro 3-5 ngwa ngwa karịa ibe n'ibe tri-cone.

3. Ego ego

Mpekere PDC na-echekwa ego. N'ihi na PDC ibe n'ibe na-agbawa ngwa ngwa, enwere ọtụtụ oge echekwara. Oge echekwara na-enye ohere ka onye na-egwupụta ihe rụchaa ọtụtụ ọrụ n'ime obere oge. Na obere ọrụ, a na-echekwa awa na ụbọchị. Na nnukwu ọrụ, a na-echekwa izu na ọnwa. Uru nke imecha ọrụ ahụ ngwa ngwa ga-agụnye ịchekwa ego na awa mmadụ na mmanụ ụgbọala, nzute na/ma ọ bụ gafere oge njedebe, na iji obere ihe na ihe oriri.

N'ozuzu, enwere ọtụtụ uru iji jiri ibe PDC gwuo ala. Dị ka ihe ọ bụla ọzọ, ụlọ ọrụ na-egwupụta ihe na-agbanwe mgbe niile. Mgbanwe na teknụzụ na mkpọpu nwere ike ịbụ nnukwu ihe. Mpekere PDC nwere ike ịbụ mgbanwe na-eme gị ihe dị iche.
