Uyini umehluko phakathi komzimba wensimbi nomzimba we-matrix PDC bit

I-PDC drill bit yenziwa kakhulu ngabasiki be-PDC kanye nensimbi, okuhlanganisa ukuqina okuhle kwensimbi kanye nokumelana nokuguguleka kwe-polycrystalline diamond compact kwenza i-PDC bit ibe ne-footage esheshayo enqubweni yokubhoboza. I-PDC bit yomzimba wensimbi inesivinini esisheshayo ekwakhekeni okuthambile kuyilapho i-PDC bit yomzimba we-matrix imelana kakhulu nokuguguleka, i-matrix body bit ingabhoboza ukwakheka okuqinile uma iqhathaniswa ne-PDC bit yomzimba wensimbi ngenxa yomzimba wayo we-tungsten carbide matrix, kodwa ine-footage ehamba kancane uma iqhathaniswa ne-PDC drill bit yomzimba wensimbi. Uma unesithakazelo kunoma yimaphi ama-PDC bits, sicela uxhumane neFar Eastern Drilling.

Ama-Matrix Body PDC Bits vs. Ama-PDC Bits Omzimba Wensimbi

Uma ususebenze ekubholeni isikhathi eside, kungenzeka ukuthi uke wezwa ngama-PDC bits. I-PDC imele ukuthi “i-polycrystalline diamond compact,” echaza i-compound yezinto ezakha indawo yokusika yalezi zingcezu. Zombili i-Matrix Body PDC kanye ne-Steel Body PDC zenziwe ngale compound.

Lezi zingcezu zinamagama amaningi. Zivame ukubizwa ngokuthi:

• Amabhithi e-PDC
• Amabhithi amancane edayimane e-polycrystalline
• Izingcezu zamazinyo ezinama-chip ahlanganisiwe
• Izingcezu zebhulokhi yokusika idayimane ye-polycrystalline

Ama-PDC bits avame ukusetshenziselwa ukubhoboza uwoyela - kodwa athandwa nakwezinye izimboni. Adalwa ngo-1976 futhi asathandwa namanje njengoba kunjalo nangamanje.amabhithi e-roller-cone(uhlobo lwengxenye enezingxenye ezijikelezayo). Nakuba ama-bits e-PDC enomlando omude wempumelelo, ayaqhubeka nokuguquka futhi athuthuka njalo ngokusebenzisa ama-engeli amasha namasu okusika, amalungiselelo, nezinto zokwakha. Lawa ma-bits asebenza kahle kakhulu njengoba esebenza ukugunda ukwakheka kwamatshe kunokuzichoboza. Unyaka ngamunye, intuthuko entsha kwezobuchwepheshe ithuthukisa ukusebenza kahle kwama-bits e-PDC futhi ithuthukise isivinini sokubhoboza.

Lezi zingcezu zaziwa ngokuthi “izingcezu ezisuka ekhaleni ziye etsheni” embonini yokubhoboza – zenza umsebenzi futhi zingasebenza kahle kakhulu ezinhlotsheni eziningi zezinsizakalo kanye nezinhlobo zokwakheka—azikho izingxenye ezihambayo ezizovinjwa, akukho nkinga, ukubhoboza okusebenzayo kuzo zonke izidingo zakho.

Ayini Ama-PDC Bits?

Kunezindlela ezimbili eziyinhloko ze-Izingcezu zokubhoboza ze-PDC– ama-PDC body bits kanye nama-PDC body bits ensimbi. Womabili ama-bits ayindilinga anesimo esifanayo anezakhiwo zokusika ezine kuya kweziyisishiyagalombili, noma ama-blade, aphuma phakathi nendawo. I-blade ngayinye ibe isiphezulu ngezicuphi eziphakathi kweshumi namashumi amathathu. Ama-bits anemisele yamanzi esakazekile ukuze aphole, futhi kukhona i-nozzle esicongweni se-bit. Uma uzama ukucabanga ngale ngxenye, ibukeka njengomqhele inkosi engase iwugqoke.

Ama-bits e-PDC asetshenziselwa ukumba uwoyela negesi, ukumba komhlaba, ukumba imithombo yamanzi, ukumba ukwakhiwa, ukumbiwa kwemigodi kanye nokumba okuqondile.

Isayensi Engemuva Kwezingcezu Ze-PDC

Kungenzeka ukuthi uke wafunda esikoleni ukuthi idayimane liyinto enzima kunazo zonke ezaziwayo kumuntu. Linjalo! Futhi lilungele ukusika ezinye izinto ezifana nokwakheka kwamatshe okubhoboza.

Ama-bits e-PDC asebenzisa amadayimane amancane, angabizi, enziwe ngabantu ezakhiweni zawo zokusika. Inqubo yokwakha amadayimane kulezi zingcezu iyinkimbinkimbi. Kulula, nansi inqubo yokwakha ama-bits okubhoboza amadayimane:

• Kwenziwa amadayimane amancane okwenziwa
• Amadayimane abe esehlanganiswa abe yizinqwaba ezinkulu zamakristalu
• Amakristalu abe esebunjwa abe amatafula edayimane
• Amatafula edayimane abe esehlanganiswa nensimbi, ngokuvamile i-tungsten carbide, kanye ne-metallic binder.
• Lokhu kuba yingxenye yokusika ye-bit - kunezicucu eziningi ebaleni ngalinye le-bit
• Izicucu zibe sezinamathiselwa ezinsikeni, ezinamathiselwe emzimbeni we-bit

Ndawonye, ​​izicucu kanye nama-blade asesiqongweni se-PDC bit asetshenziselwa ukusika izinhlobo ezahlukene zamatshe.

Amadayimane Okwenziwa Ezingcezu Zokubhoboza

Njengoba ubona, amadayimane okwenziwa ayizinto ezibalulekile zama-bits e-PDC. Ekwenzeni la ma-bits, kudalwa izinhlamvu ezincane kakhulu zedayimane (ezibizwa nangokuthi i-diamond grit). Le grit ihlala isikhathi eside kodwa ayizinzi ezingeni lama-molecule uma ishisa. Ngakho-ke, i-PDC bit yakho ingase yehluleke uma ingapholiswanga ngokwanele uma isetshenziswa.

Noma kunjalo, amadayimane okwenziwa awagugi kakhulu; ayizinto ezifanele kakhulu ukuze ahlale isikhathi eside futhi ahlale isikhathi eside. Uhlobo lwensimbi luyashintsha uma ukhetha i-matrix noma i-steel body bit - kodwa idayimane ibalulekile. Ama-PDC bits angaba nesikhathi eside sokuphila uma nje epholile ngokwanele.
