PDC drill bit imapangidwa makamaka ndi odulira a PDC ndi chitsulo, kuphatikiza kulimba kwa chitsulo komanso kukana kuwonongeka kwa polycrystalline diamond compact kumapangitsa kuti PDC bit ikhale ndi malo ofulumira pakubowola. Thupi lachitsulo PDC bit limakhala ndi liwiro lofulumira pakupangidwa kofewa pomwe matrix body PDC bit ndi yolimba kwambiri, matrix body bit imatha kubowola molimba poyerekeza ndi chitsulo PDC bit chifukwa cha tungsten carbide matrix body yake, koma imakhala ndi malo ocheperako poyerekeza ndi chitsulo PDC drill bit. Ngati mukufuna chilichonse mwa ma PDC bits, chonde lemberani Far Eastern Drilling.
Matrix Body PDC Bits vs. Steel Body PDC Bits
Ngati mwakhala mukugwira ntchito yoboola kwa nthawi yayitali, mwina mwamvapo za PDC bits. PDC imayimira "polycrystalline diamond compact," yomwe imafotokoza chinthu chomwe chimapanga pamwamba pa kudula kwa ma bits awa. Matrix Body PDC ndi Steel Body PDC onse amapangidwa ndi chinthuchi.
Zidutswa zimenezi zili ndi mayina ambiri. Nthawi zambiri zimatchedwa:
- Ma PDC Bits
- Zidutswa zazing'ono za diamondi za polycrystalline
- Zidutswa za mano zopangidwa ndi chip cha Composite
- Zidutswa zodulira diamondi za polycrystalline
Zidutswa za PDC nthawi zambiri zimagwiritsidwa ntchito pobowola mafuta - koma ndizodziwika bwino m'mafakitale ena. Zinapangidwa mu 1976 ndipo zikudziwikanso masiku ano monga momwe zilili ndizidutswa za roller-cone(mtundu wa chidutswa chomwe chili ndi zigawo zozungulira). Ngakhale kuti zidutswa za PDC zakhala zikuyenda bwino kwa nthawi yayitali, zimapitilizabe kusintha ndikusintha nthawi zonse kudzera mu ngodya zatsopano komanso zatsopano zodulira, makonzedwe, ndi zipangizo. Zidutswa izi ndi zothandiza kwambiri chifukwa zimagwira ntchito yodula miyala m'malo moziphwanya. Chaka chilichonse, kupita patsogolo kwatsopano muukadaulo kumawongolera magwiridwe antchito a zidutswa za PDC ndikuwonjezera liwiro la kubowola.
Zidutswa zimenezi zimadziwika kuti ndi “zidutswa zoyambira pamphuno mpaka pamwala” zomwe zimagwiritsidwa ntchito pobowola – zimagwira ntchito bwino ndipo zimatha kukhala zothandiza kwambiri pa ntchito zosiyanasiyana komanso mitundu yosiyanasiyana ya mapangidwe—palibe zinthu zosuntha zomwe zingatsekedwe, palibe vuto, kungobowola bwino zomwe zingakuthandizeni pa zosowa zanu zonse.
Kodi Ma PDC Bits Ndi Chiyani?
Pali mitundu iwiri yoyambirira yaZidutswa za PDC zobowola– matrix body PDC bits ndi steel body PDC bits. Zonsezi ndi zozungulira zofanana ndi zomangira zinayi mpaka zisanu ndi zitatu, kapena masamba, omwe amatuluka pakati. Tsamba lililonse limayikidwa pamwamba pa zodulira pakati pa khumi ndi makumi atatu. Zidutswazo zimakhala ndi ngalande zamadzi zomwe zimafalikira kuti zizizire, ndipo pali nozzle pamwamba pa chidutswacho. Ngati mukuyesera kuganiza za chidutswa ichi, chikuwoneka ngati korona yomwe mfumu ingavale.
Zidutswa za PDC zimagwiritsidwa ntchito pobowola mafuta ndi gasi, kubowola geothermal, kubowola zitsime zamadzi, kubowola zomangamanga, migodi ndi kubowola mbali zonse.
Sayansi Yokhudza Ma PDC Bits
Mwina munaphunzira kusukulu kuti diamondi ndi chinthu chovuta kwambiri chomwe anthu amadziwa. Ndicho! Ndipo ndi chabwino kwambiri podula zinthu zina monga miyala yoboolera.
Zidutswa za PDC zimagwiritsa ntchito diamondi zazing'ono, zotsika mtengo, zopangidwa ndi anthu popanga ma diamondi awo. Njira yopangira diamondi pazidutswa izi ndi yovuta. Zosavuta, nayi njira yopangira zidutswa za diamondi:
- Ma diamondi ang'onoang'ono opangidwa amapangidwa
- Kenako ma diamondi amasonkhanitsidwa kukhala makhiristo ambiri.
- Kenako makhiristo amapangidwa kukhala matebulo a diamondi
- Matebulo a diamondi amalumikizidwa ku chitsulo, nthawi zambiri tungsten carbide, ndi chomangira chachitsulo.
- Izi zimakhala gawo lodulira la chidutswa - pali zodulira zambiri pa tsamba lililonse la chidutswacho
- Kenako zodulirazo zimalumikizidwa ku masamba, omwe amalumikizidwa ku thupi la chidutswacho
Pamodzi, zodulira ndi masamba omwe ali pamwamba pa chidutswa cha PDC zimagwiritsidwa ntchito kudula miyala yamitundu yonse.
Ma Dayamondi Opangidwa mu Drill Bits
Monga mukuonera, ma diamondi opangidwa ndi zinthu zofunika kwambiri popanga ma PDC bits. Popanga ma diamondi amenewa, timadontho tating'ono kwambiri ta diamondi (omwe amatchedwanso diamond grit) timapangidwa. Ma diamondi amenewa ndi olimba kwambiri koma sakhazikika bwino akamatenthedwa. Chifukwa chake, PDC bit yanu imatha kulephera ngati siizizira bwino ikagwiritsidwa ntchito.
Komabe, ma diamondi opangidwa ndi zinthu zachilengedwe satha kutha; ndi zinthu zoyenera kwambiri kuti munthu akhale ndi moyo wautali komanso wolimba. Mtundu wa chitsulo umasintha ngati mutasankha matrix kapena chitsulo - koma diamondi ndi yofunika kwambiri. Ma PDC bits amatha kukhala ndi moyo wautali bola ngati atazizidwa bwino.
Matrix Body PDC Bits
Matrix body bits ndi amodzi mwa mitundu yotchuka kwambiri ya ma PDC bit. Amapangidwa ndi zinthu zophatikizika zomwe zimakhala zolimba komanso zofooka. Zinthuzo zimapangidwa ndi tinthu ta tungsten carbide tomwe timalumikizidwa ndi chomangira chachitsulo chofewa komanso cholimba. Ngakhale kuti ma Matrix body bits si olimba kwambiri polimbana ndi kugunda, ali ndi kukana kwabwino kwambiri kwa kukwawa kuposa ma PDC body bits achitsulo.
Zidutswa za thupi la matrix zimapangidwa pogwiritsa ntchito nkhungu yotenthedwa mu uvuni. Nkhunguyo imadzazidwa ndi chitsulo chosakanikirana mu mawonekedwe olimba, imatenthedwa kuti isungunuke, iziziritsidwe, kenako n’kusonkhanitsidwa ndi zodulira.
Kugwiritsa Ntchito Matrix Body PDC Bits
Matrix body PDC bits amagwiritsidwa ntchito makamaka pa ntchito izi:
- Mapangidwe ofewa mpaka apakati olimba
- Kuchuluka kwa voliyumu
- Mchenga wautali
- Mapulogalamu omwe gawo lomwelo lidzafunika kugwiritsidwa ntchito poyendetsa ma bit angapo
Zidutswa za PDC za Thupi la Chitsulo
Ma PDC bits a thupi lachitsulo ndi ena mwa mitundu yodziwika bwino ya ma PDC bit. Ma bits awa ndi osiyana ndi matrix bit mu kapangidwe kake. Amapangidwa kuchokera ku chitsulo m'malo mwa chitsulo chomwe chimagwiritsidwa ntchito popanga matrix body PDC bits. Ndi abwino kwambiri pakulimbana ndi impact koma nthawi zambiri amawonongeka chifukwa cha kukokoloka.
Zidutswa zachitsulo za PDC zimagwiritsa ntchito kudula kwa chidutswacho kuti ziswe mwala womwe chikuboolera. Nthawi zambiri zimakhala zokhazikika ndipo zimatha kuboolera mofulumira kwambiri.
Zidutswa zimenezi zimapangidwa ndi zitsulo. Zidutswazo zimapangidwa ndi makina opangidwa ndi zitsulo ndi ma lathes kuti apange thupi la chidutswacho, kenako mano odulira ndi nsanamira zimalumikizidwa nazo. Zidutswa zachitsulo za PDC zimapangidwa mosavuta kukhala mawonekedwe ndi mapangidwe ovuta. Kupanga mapangidwe ovuta kumathandiza kuti pakhale mitundu yosiyanasiyana ya mawonekedwe odulira ndi mawonekedwe. Kusiyanasiyana kwa mawonekedwe odulira kungakhale kothandiza pobowola miyala yapadera.
Kugwiritsa Ntchito Zidutswa za PDC za Thupi la Chitsulo
Zidutswa za PDC za thupi lachitsulo ndizothandiza pazinthu zomwe zimaphatikizapo:
- Kubowola mapangidwe a shale
- Malo ofewa a miyala yamchere
- Kuboola mwachangu m'magawo
- Kuboola gasi wachilengedwe
- Zitsime zakuya
- Mapangidwe okhwima
Gulani Ma PDC Bits Pa intaneti
Kusankha wogulitsa ma PDC bits kungakhale ntchito yovuta kwambiri. Ngakhale pali njira zambiri zabwino zoti musankhe, Far Eastern Driling Bit ndi kampani yodziwa bwino ntchito yokhala ndi zinthu zambiri ku China. Mutha kudziwa zambiri kuchokera patsamba lawebusayiti www.chinafareast.com
