Nā Kola wili
ʻO ke kola wili ma ke ʻano he mea hoʻokahi o ke kaula drill he mau tubular ʻoihana nui ia i hoʻohana ʻia e wili i ka lepo e hāʻawi i ke kaumaha ma luna o ka bit no ka wili ʻana.Hoʻohana ʻia e hui pū me ka paipu drill.Loaʻa nā ʻano slick a me spiral grooved ka nui.Ua hōʻoia ʻia kā mākou hana hana i ka API spec 7-1.Hana ʻia ke kola drill me AISI 4145 H a i ʻole 4145 H Modified alloy steel.Wehe ʻia nā pahu mai kahi ʻaoʻao me ka like ʻole.Hoʻomaʻamaʻa ʻia nā kola drill āpau me ka paʻakikī i loko o 285 a 341 BHN, i hōʻoia ʻia i hoʻokahi iniha ma lalo o ka ʻili o ka paipu.
Hāʻawi nā kola drill non-magnetic i ka ikaika a me ka paʻakikī i ka wā e pale ana i ka hoʻopili magnetic e hōʻino paha i ka pololei o nā anana magnetic.Hana ʻia ia mai nā mea kila kūikawā me ka haʻahaʻa haʻahaʻa, nā waiwai mechanical kiʻekiʻe a me ke kūpaʻa kiʻekiʻe i ka haki ʻana i ka corrosion.
Hāʻawi mākou i nā kola drill slick, nā kola drill spiral a me nā collar drill non-magnetic;ko lakou nui mai 3-1/8 a 11 iniha.Ma waho aʻe o nā kola drill ma ka papa ma lalo nei, hiki iā mākou ke hoʻolako i nā kola drill ʻē aʻe ma ke noi a nā mea kūʻai aku.

Drill collars mea he integral kaumaha hana hui i kūkulu 'ia mai ka paa paa o AISI 4145H hoololiia alloy kila.?Hāʻawi ʻia kā mākou mau kolamu drill maʻamau me kahi kūlana hoʻopau ʻili "e like me ka ʻōwili ʻia".Loaʻa i nā pahu maʻamau a pau ka hoʻomaʻamaʻa wela e hāʻawi iā lākou i nā pono mechanical pono.
Hoʻopaʻa ʻia nā kaola a hoʻoheheʻe ʻia.Hana ʻia nā kola drill a pau i loko
e like me ka API spec 7, Q1 a me ka hoʻomaʻamaʻa 7G i ʻōlelo ʻia, e like me ka pili.
