Mkpebi dị mkpirikpi nke PDC drill bit
Polycrystalline diamond compact (PDC) ka a na-eji ihe na-egbutu diamond sịntetik n'ụdị ahụ nchara ma ọ bụ matriks ahụ. PDC drill bits gbanwere ụlọ ọrụ egwu egwu nwere nnukwu ngwa ngwa yana ikike ntinye dị elu (ROP).

A haziri ma rụpụta PDC Bits dị ka:

§Matrix-ahụ bit

§Steel-ahụ ibe n'ibe

MATRIX-ahụ
Matrix bụ ihe siri ike na nke na-emebi emebi nke mejupụtara ọka tungsten carbide n'ụzọ igwe ejikọtara ya na ihe dị nro, sie ike, nke ọla. Ọ na-egbochi mbuze karịa ígwè. A na-ahọrọ ha na apịtị na-egwupụta ihe dị elu.

Uru-
1. Matrix bụ ihe a na-achọsi ike dị ka ihe dị ntakịrị karịa nchara n'ihi na isi ike ya na-eguzogide abrasion na mbuze.
2. O nwere ike iguzogide ibu mkpakọ dịtụ elu.
3. Maka ibe n'ime diamond, naanị matriks-ahụ ka a ga-eji mee ihe.

ọghọm -
1. Tụnyere ígwè, ọ nwere obere nguzogide n'ikwado mmetụta.
2. Mmetụta siri ike nke matrik ahụ na-amachi ụfọdụ atụmatụ matriks-bit, dị ka ịdị elu agụba.

NLA-ahụ
Steel bụ metallurgically megide matriks. A na-ahọrọkarị ibe n'ụdị nchara nchara maka nhazi dị nro na nke anaghị emebi emebi na nnukwu oghere. Iji belata nbibi anụ ahụ, ibe n'ibe na-enwe ihu siri ike na ihe mkpuchi nke na-egbochi mbuze na mgbe ụfọdụ na-enweta ọgwụgwọ mgbochi ịgba bọọlụ maka nhazi nkume na-arapara nke ukwuu dị ka shales.

Uru-
1. Steel bụ ductile, siri ike, ma nwee ike idi ibu mmetụta ka ukwuu.
2. O nwere ike iguzogide ibu mmetụta dị elu, mana ọ dị nro na, na-enweghị njirimara nchebe, ọ ga-ada ngwa ngwa site na abrasion na mbuze.
3. N'ihi ike ihe nchara, profaịlụ bit gbagwojuru anya na nhazi hydraulic ga-ekwe omume yana ọ dị mfe iji wuo n'igwe ọtụtụ axis, igwe igwe igwe na-ejikwa ọnụọgụ kọmputa.

ọghọm -
1. Anụ igwe anaghị egbochi mbuze karịa matriks, yabụ, ọ na-enwe ike iyi ya site na mmiri na-ekpo ọkụ.


PDC ibe n'ibe na-akpụ akpụ bụ isi site n'ịkpacha ihe. A na-ebunye ike ntinye kwụ ọtọ site na ibu etinyere na bit na ike kwụ ọtọ site na tebụl rotary n'ime ndị na-egbutu ya. Ike nke nsonaazụ na-akọwa ụgbọ elu nke mkpali maka cutter. A na-akpụzi mkpụkpụ n'akụkụ mbụ n'akụkụ ụgbọ elu nke mbuli, nke dabere na ike nkume.

Oke ngwa ngwa maka ibe n'ibe PDC chọrọ teknụzụ cutter PDC pụrụ iche iji nweta arụmọrụ kacha arụ ọrụ na ngwa ọ bụla. Pọtụfoliyo kacha mma ga-ebuli arụmọrụ na ịma aka mgbapu ọ bụla.
