Uyini umehluko phakathi komzimba wensimbi kanye ne-matrix body PDC bit

I-PDC drill bit yenziwa ikakhulukazi abasiki be-PDC nensimbi, okuhlanganisa ukuqina komthelela omuhle kwensimbi nokungagugi kwe-polycrystalline diamond compact kwenza i-PDC bit ibe nesithombe esisheshayo enqubweni yokumba. Ibhithi yensimbi ye-PDC inejubane elisheshayo ekubunjweni okuthambile kuyilapho i-matrix body PDC bit imelana kakhulu nokugqokwa, i-matrix body bit ingabhola ukwakheka okuqinile uma iqhathaniswa nensimbi yomzimba we-PDC bit ngenxa yomzimba wayo we-tungsten carbide matrix, kodwa inezithombe ezihamba kancane lapho. uma kuqhathaniswa nensimbi yomzimba we-PDC yokubhoboza kancane. Uma unentshisekelo kunoma yimaphi amabhithi e-PDC, pls xhumana ne-Far Eastern Drilling

I-Matrix Body PDC Bits vs. Steel Body PDC Bits

Uma usebenze ekubholeni nganoma yisiphi isikhathi, kungenzeka ukuthi uzwile ngezingcezu ze-PDC. I-PDC imele “i-polycrystalline diamond compact,” echaza inhlanganisela yezinto eyenza lezi zingcezu ezisikwayo. Kokubili i-Matrix Body PDC kanye ne-Steel Body PDC zenziwe ngale nhlanganisela.

Lezi zingcezu zihamba ngamagama amaningi. Avame ukubizwa ngokuthi:

• Izingxenye ze-PDC
• I-polycrystalline diamond compact bits
• Izinyosi ze-chip ezihlanganisiwe
• Izingcezu ze-polycrystalline diamond cutting block

Amabhithi e-PDC avame ukusetshenziselwa ukumba uwoyela - kodwa adumile nakwezinye izimboni. Zadalwa ngo-1976 futhi zithandwa kakhulu manjeizingcezu ze-roller-cone(uhlobo lwebhithi elinezingxenye ezijikelezayo). Nakuba amabhithi e-PDC anomlando omude wempumelelo, ayaqhubeka nokuvela futhi athuthuke njalo ngokusebenzisa ama-engeli amasha namasha wokusika, amalungiselelo, nezinto zokwakha. Lezi zingcezu zisebenza kahle kakhulu njengoba zisebenzela ukugunda ukwakheka kwamadwala kunokuwachoboza. Unyaka ngamunye, intuthuko entsha kwezobuchwepheshe ithuthukisa ukusebenza kwe-PDC bits futhi ithuthukise isivinini sokumba.

Lezi zingcezu zaziwa ngokuthi izingcezu ze-"nose-to-the-grindstone" zemboni yokumba - zenza umsebenzi wenziwe futhi zingasebenza ngempumelelo ezinhlobonhlobo zezinsizakalo nezinhlobo zokubunjwa—azikho izingxenye ezinyakazayo ukuze ziminyaniswe, cha. ukuxabana, ukubhoboza okusebenzayo kuzo zonke izidingo zakho.

Ayini ama-PDC Bits?

Kunezitayela ezimbili eziyinhloko zeIzingxenye zokugaya ze-PDC- Izingcezu ze-PDC zomzimba we-matrix kanye nezingcezu ze-PDC zomzimba wensimbi. Zombili ziyizicucu eziyindilinga ezimise ngendlela efanayo ezinezakhiwo zokusika ezine kuya kweziyisishiyagalombili, noma izindwani, eziphephetha phakathi nendawo. I-blade ngayinye ibe isiqoqwa ngabasiki abaphakathi kweshumi namashumi amathathu. Izingcezu zinemigudu yamanzi ehlakazekile ukuze iphole, futhi kukhona umbhobho phezulu kwebhithi. Uma uzama ukucabanga lokhu okuncane, kubukeka kufana nomqhele inkosi engase iwugqoke.

Izingcezu ze-PDC zisetshenziselwa ukumba uwoyela negesi, ukumba i-geothermal, ukubhola umthombo wamanzi, ukumba ukwakhiwa, ukumba izimayini kanye nokubhola okuqondisayo.

Isayensi Ngemuva kwe-PDC Bits

Kungenzeka ukuthi uye wafunda esikoleni ukuthi idayimane liyinto enzima kunazo zonke ezaziwayo kumuntu. Ikona! Futhi ilungele ukusika kwezinye izinto ezifana namatshe okwakhiwa kokumba.

Amabhithi e-PDC asebenzisa amadayimane amancane, angabizi, enziwe umuntu ezakhiweni zawo zokusika. Inqubo yokudala amadayimane kulezi zingcezu iyinkimbinkimbi. Esenziwe lula, nansi inqubo yokudala izingcezu zokumba idayimane:

• Amadayimane amancane okwenziwa ayenziwa
• Amadayimane abe esehlanganiswa abe izixuku 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 yebhithi - kukhona abasiki abaningi ku-blade ngayinye yebhithi
• Khona-ke abasiki bahlanganiswa nama-blades, ahlanganiswe nomzimba we-bit

Ndawonye, ​​ama-cutters nama-blades esicongweni sebhithi ye-PDC asetshenziselwa ukusika ukwakheka kwamadwala azo zonke izinhlobo.

Amadayimane Okwenziwa ku-Drill Bits

Njengoba ubona, amadayimane okwenziwa ayizinto ezibalulekile zamabhithi e-PDC. Ekukhiqizeni lezi zinhlamvu, izinhlamvu zedayimane ezincane kakhulu (ezibizwa nangokuthi i-diamond grit) ziyadalwa. Le grit iqinile kakhulu kodwa iyancipha kancane ezingeni lamangqamuzana lapho ishisa. Ngakho-ke, ibhithi lakho le-PDC cishe lingahluleka uma lingapholiswanga ngokwanele lapho lisetshenziswa.

Kungakhathaliseki ukuthi, amadayimane okwenziwa amelana ngendlela emangalisayo; ziyizinto ezifanele zokuphila isikhathi eside nokuqina. Uhlobo lwensimbi luyashintsha uma ukhetha i-matrix noma insimbi yomzimba wensimbi - kodwa idayimane libalulekile. Izingcezu ze-PDC zingaphila isikhathi eside inqobo nje uma zipholile ngokwanele.
