ʻO ka ʻūmiʻi daimana PDC kino Matrix M137 5 7/8 ʻīniha (149mm)

ʻO ka API M137 5 7/8 ʻīniha ke kino matrix PDC daimana wili ʻāpana i loko o ka waihona mai ka mea hoʻolako Kina.
Hoʻonui ka 7 mau pahi a me nā mea ʻokiʻoki lālani pālua i ka hiki ke ʻeli i nā pōhaku paʻakikī, lawe mai ke kino matrix i ke ola ʻeli lōʻihi.
ʻO 5 7/8" ka ʻāpana lua lalo loa i hohonu loa, i kekahi manawa ʻoi aku ka hohonu ma mua o 3500 mika, kiʻekiʻe loa ke kumukūʻai o ka hoʻololi ʻana i ka bit i ka ʻeli ʻana i ka lua hohonu, no laila e pili ana i ka PDC Diamond Drill Bit, he mea nui loa ka manawa holo a me ka wikiwiki o ke komo ʻana.
Noi:
Nā ʻano paʻakikī me ka ikaika compressive kiʻekiʻe, e like me ka shale paʻakikī, ka limestone, ka one pōhaku, ka dolomite, a pēlā aku
Nā Hiʻohiʻona:
He ʻāpana matrix body PDC ka M137 me 7 mau pahi wili me ka pale back-reaming a me ka pale spiral gauge.
Hoʻolālā Hydraulic i hoʻomaikaʻi ʻia a me nā hopena hoʻomaʻemaʻe a hoʻomaʻalili hoʻi o nā ʻāpana e pale aku i ka bit-balling.
ʻO ka bit PDC he Polycrystalline Diamond Compact bit, ua kapa ʻia hoʻi ʻo ia he Diamond bit. Wahi a ka hoʻokaʻawale ʻana o nā mea, he kino matrix a he kino kila ko nā bit PDC.
Hana ʻia ka ʻāpana PDC kino matrix e ka pauka tungsten carbide, a ʻo ka pale ana o ke ana ʻo TSP. ʻO ke kila kila PDC bit he kila lapaʻau wela AISI 4145H (kila maʻamau ʻAmelika), nā ʻeke wili mīkini CNC kiʻekiʻe, ka pahi, nā nozzles.
