Ma nā ʻano paʻakikī waena ākea o Saudi Arabia—ka pōhaku limestone, ka dolomite, a me ka one pōhaku i hoʻohui ʻia—ua pilikia pinepine nā mea ʻoki PDC pālahalaha maʻamau me ka lohi o ka komo ʻana a me ka hoʻonele ikehu kiʻekiʻe. Hoʻololi nā koʻi axe a me nā mea ʻoki ʻano triangular i ka pāʻani ma ka hoʻoikaika ʻana i ke kaumaha, ka hōʻemi ʻana i ka ikaika ʻoki, a me ka hāpai nui ʻana iā ROP. Ke alakaʻi nei ʻo Ninestones Superabrasives i kēia hoʻololi pono me ka hana kiʻekiʻe.Nā hoʻokomo Pdc Kinai hoʻolālā ʻia no ka ʻeli ʻana ma ke kahua maoli.
ʻAno ʻoki: Shaped vs. Flat PDC
Hilinaʻi nā mea ʻoki pālahalaha i ka ʻoki piha piha, kahi e hana ai i ke kū'ē kiʻekiʻe a me ka pōpō i ka pōhaku paʻakikī waena. Hōʻike ka ʻikepili mai AADE (American Association of Drilling Engineers) i nā mea ʻoki i hoʻohana ʻia i ka hoʻokomo ʻana i ka ukana kiko e hana i ka pōhaku ma mua o ka haki ʻana, e ʻoki ana i ka MSE (Mechanical Specific Energy) a hiki i ka 35%.
Hoʻohana nā mea hoʻokomo ʻano koʻi i kahi kualono ʻoi e māhele mua i ka pōhaku, a laila ʻoki. Hoʻohana nā mea hoʻokomo prismatic triangular i ʻekolu mau ʻaoʻao symmetric no ka haki paʻa a hoʻomau. ʻOi aku ka wikiwiki o ka ʻeli ʻana o nā geometries ʻelua me ka WOB liʻiliʻi, e hāpai pololei ana iā ROP.
A hiki i ka 35% ka hōʻemi ʻana i ka Mechanical Specific Energy (MSE)— i hōʻoia ʻia e ka ʻikepili kahua AADE me ka hoʻohana ʻana i ke ʻano ʻokiʻoki PDC i hoʻohālikelike ʻia.
No ke aha i hoʻokomo ai ʻo Shaped China Pdc iā Excel ma ka Medium-Hard Rock

1
Ka hoʻoikaika ʻana i ke kaumaha no ka maʻalahi o ka haki ʻana i ka pōhaku
2
ʻO ka torque haʻahaʻa a me ka haʻalulu no ka ʻeli ʻana maʻalahi

ʻAno o NinestonesNā hoʻokomo Pdc Kinahoʻohui i ka geometry i hoʻonui ʻia me ka PCD kiʻekiʻe, ke kaulike ʻana i ka wikiwiki a me ka paʻakikī ma mua o nā mea ʻoki pālahalaha maʻamau.
Hihia Kahua: Lele ROP i nā ʻAno Carbonate Saudi
Ua hoʻāʻo kahi hui ʻeli ma nā kahua kalapona waena o Saudi Arabia i ka hana a Ninestones.Nā hoʻokomo Pdc Kinae kūʻē i nā mea ʻoki pālahalaha maʻamau:
| ʻAno ʻoki | ROP | Kūlana |
|---|---|---|
| Nā mea ʻoki pālahalaha | 2.1 m/h | Hoʻopili pinepine ʻia |
| Nā Hoʻokomo Pdc Kina i Hoʻohālike ʻia | 3.4 m/h(+62%) | ʻAʻohe ʻokiʻoki |
Ua hoʻopau ʻia ka ʻāpana luawai i 1.5 mau lā ma mua, e hōʻemi ana i ka huina kumukūʻai ma 28%. Ua hōʻoia nā luna o ke kahua ua mālama ʻia ka ʻoi o nā mea hoʻokomo i hoʻohālikelike ʻia no ka manawa lōʻihi.

E pili ana i ka Mea Kākau
ʻO Khalid Al-Faraj, he ʻenekinia ʻeli ma Dammam, Saudi Arabia, he 19 mau makahiki o ka ʻike ma nā hana ʻaila a me ke kinoea ma uka ma ke Aupuni. He loea ʻo ia i ka hoʻonui ʻana i ka PDC bit, ka hoʻomaikaʻi ʻana i ka ROP, a me ke koho ʻana i nā mea hana i hoʻololi ʻia i ke ʻano.
"ʻO kā lākouNā hoʻokomo Pdc Kinaʻo ia nā huahana PDC ʻoi loa ke ʻano aʻu i hoʻohana ai ma nā ʻano Saudi. Hāʻawi lākou i nā loaʻa ROP mau, ka lōʻihi maikaʻi, a me ka lako hilinaʻi. No kekahi mea hoʻohana e manaʻo ana e wikiwiki i ka ʻeli ʻana i ka paʻakikī waena, ʻo Ninestones ke koho kiʻekiʻe loa.
