PDC bit yakashandisa kuchera mafuta negasi zvakadzama, kuchera matombo akaomarara, kuchera matsime emvura inopisa, uye mapurojekiti ezvivakwa zvehukuru hwakakura.

1. Kusapfeka Kwakanaka Kwazvo Pakugadzirwa Kwakaoma. Yakagadzirwa ne tungsten carbide matrix ine density yakakura, bit iyi inodzivirira kukuvadzwa kwakanyanya mumatombo akaoma (semuenzaniso, granite, quartzite) uye munzvimbo dzine pressure/high-temperature (HPHT). Inoderedza kupera kwema bit ne30%+ zvichienzaniswa nema matrix bits akajairwa, zvichiita kuti igare kwenguva refu mumamiriro ezvinhu akaoma ekuboorera.

2. Kushanda Nesimba Kwekuchera & Kupinda Mukati Mechigadziko Chimiro chekucheka chakagadziridzwa chine dhizaini yekucheka yePDC yakagadziridzwa uye angle yekumashure inokwidziridza kubata kwematombo akaomarara. Inoita kuti ROP (Rate of Penetration) ive yakakwira ne25-40% kupfuura ma roller cone bits echinyakare, ichipfupisa maitiro ekuchera uye ichideredza mari yekuchera pa-foot.

3. Kusimba Kwakasimba uye Kuramba Kushanda Kwemavhiri. Kugadzika kwemuviri we matrix kwakasimbiswa kunovandudza kusimba kwechimiro, zvichiita kuti chidimbu chigone kumira kuzununguka kwakanyanya uye kushanduka-shanduka kwe torque mudombo rakaoma rakatyoka. Kunoderedza kukuvara kwemavhiri uye kutadza kushanda zvakanaka, kuderedza kuwanda kwekugumburwa uye nguva isingabudisi zvibereko (NPT).

4. Hunhu Hwakanaka Hwemaburi & Kugadzikana Kwemaburi. Dhizaini yepamusoro yehydraulics inoita kuti zvidimbu zvibviswe zvakanaka, kudzivirira kubhururuka uye kunamira muzvikamu zvakaoma. Inochengetedza dhayamita yemaburi uye kumira zvakanaka, inoderedza matambudziko ekushandisa bhokisi uye inovandudza kushanda zvakanaka kwetsime.
