PDC drill bit inonyanya kugadzirwa nePDC cutters nesimbi, zvichibatanidza kusimba kwesimbi uye kusashanda zvakanaka kwepolycrystalline diamond compact kunoita kuti PDC bit ikwanise kudhonzwa nekukurumidza mukuita kwekuchera. Steel body PDC bit ine kukurumidza kufonzwa kwakapfava nepo matrix body PDC bit inodzivirira kufonzwa, matrix body bit inogona kufonzwa zvakasimba kana ichienzaniswa ne steel body PDC bit nekuda kwe tungsten carbide matrix body yayo, asi ine footage inononoka kana ichienzaniswa ne steel body PDC drill bit. Kana uchida chero PDC bits, ndapota taura neFar Eastern Drilling.
Matrix Body PDC Bits vs. Steel Body PDC Bits
Kana wakashanda mukuchera kwenguva yakareba, ungangove wakanzwa nezvePDC bits. PDC inomiririra "polycrystalline diamond compact," iyo inotsanangura chinhu chinoumba nzvimbo yekucheka mabits aya. Matrix Body PDC neSteel Body PDC ese anogadzirwa nechinhu ichi.
Zvidimbu izvi zvine mazita akawanda. Zvinowanzo danwa kuti:
- PDC Bits
- Zvidimbu zvemadhaimani zvePolycrystalline
- Zvidimbu zvemazino zvechip zvakasanganiswa
- Zvidimbu zvekucheka madhaimani zvePolycrystalline
Zvidimbu zvePDC zvinowanzo shandiswa pakuchera mafuta - asi zvakakurumbirawo mune mamwe maindasitiri. Zvakagadzirwa muna 1976 uye zvichiri kufarirwawo nanhasi sezvakaitazvidimbu zve roller-cone(rudzi rwechidimbu chine zvikamu zvinotenderera). Kunyange zvazvo maPDC bits ane nhoroondo refu yekubudirira, anoramba achichinja uye achiramba achivandudza kuburikidza nemakona matsva uye matsva ekucheka, kurongeka, uye zvinhu. Mabits aya anoshanda zvakanyanya sezvo achishanda kubvisa maumbirwo ematombo pane kuapwanya. Gore rega rega, kufambira mberi kutsva muhunyanzvi kunovandudza kushanda kwemaPDC bits uye kuvandudza kumhanya kwekuboora.
Zvidimbu izvi zvinozivikanwa se "zvidimbu zvinosvika paburi" zveindasitiri yekuchera - zvinopedza basa uye zvinogona kushanda zvakanaka kune akasiyana-siyana mabasa uye mhando dzekugadzira - hapana zvikamu zvinofamba zvinomanikidzwa, hapana mhirizhonga, kungochera zvinobudirira zvinoenderana nezvaunoda.
Chii chinonzi PDC Bits?
Kune nzira mbiri huru dzePDC drill bits– matrix body PDC bits uye steel body PDC bits. Ose ari maviri akafanana denderedzwa zvidimbu ane zvidimbu zvina kusvika zvisere zvekucheka, kana kuti mapanga, anobhururuka kubva pakati. Banga rega rega rinozoiswa pakati pegumi kusvika makumi matatu ekucheka. Zvidimbu zvacho zvine nzira dzemvura dzakapararira kuti dzitonhore, uye pane nozzle pamusoro pechidimbu. Kana uri kuedza kufungidzira chikamu ichi, chinoita sekorona ingapfekwa namambo.
Zvidimbu zvePDC zvinoshandiswa pakuboorera mafuta negasi, kuboorera geothermal, kuboorera matsime emvura, kuboorera kuvaka, kugoba uye kuboorera kwakatwasuka.
Sainzi Iri Kuseri Kwemabhiti ePDC
Ungave wakadzidza kuchikoro kuti dhaimani chinhu chakaoma kupfuura zvimwe zvose chinozivikanwa nevanhu. Ndizvo chaizvo! Uye chakanakira kucheka zvimwe zvinhu zvakaita sematombo ekuboorera.
Zvidimbu zvePDC zvinoshandisa madhaimani madiki, asingadhuri, akagadzirwa nevanhu mukugadzira kwavo. Maitiro ekugadzira madhaimani pazvidimbu izvi akaoma. Zviri nyore, heino maitiro ekugadzira zvidimbu zvekuboorera madhaimani:
- Madhaimani madiki ekugadzira anogadzirwa
- Madhaimani acho anobva aunganidzwa kuita makristaro makuru
- Makristaro acho anobva aumbwa kuita matafura edhaimani
- Matafura edhaimani anobva abatanidzwa nesimbi, inowanzova tungsten carbide, uye chinhu chinosunga simbi.
- Izvi zvinova chikamu chekucheka chechidimbu - kune zvidimbu zvakawanda zvekucheka pabanga rega rega rechidimbu.
- Zvinochekwa zvinosungirirwa pamashizha, ayo anosungirirwa pamuviri wechidimbu.
Pamwe chete, zvicheki nemapazi ari pamucheto wePDC bit zvinoshandiswa kucheka matombo emhando dzese.
Madhaimani Ekugadzira muDrill Bits
Sezvamunoona, madhaimani ekugadzira ndiwo anonyanya kukosha pakugadzira maPDC bits. Mukugadzira madhii aya, dhaimani diki-diki (dzinonziwo diamond grit) dzinogadzirwa. Dhaimani iyi inogara kwenguva refu asi inova isina kugadzikana padanho remamorekuru kana ichipisa. Saka, dhaimani yako yePDC inogona kukundikana kana isina kutonhodzwa zvakanaka kana ichishandiswa.
Zvisinei, madhaimani ekugadzira haaparare zvakanyanya; ndiwo akakodzera kugara kwenguva refu uye kugara kwenguva refu. Rudzi rwesimbi runochinja kana ukasarudza matrix kana simbi - asi dhaimani yakakosha. PDC bits dzinogona kugara kwenguva refu chero bedzi dzakatonhodzwa zvakanaka.
Matrix Body PDC Bits
Matrix body bits ndeimwe yemhando dzePDC bit dzinonyanya kufarirwa. Dzakagadzirwa nezvinhu zvakasanganiswa zvakaoma uye zvinoputsika. Zvinhu izvi zvakagadzirwa netungsten carbide grains dzakasungirirwa nesimbi nesimbi yakapfava uye yakasimba. Kunyange zvazvo maMatrix body bits asina kusimba zvakanyanya pakugumburwa, ane resistance iri nani pane maPDC body bits esimbi.
Zvidimbu zvemuviri we matrix zvinogadzirwa nekushandisa chakuvhuvhu chinopisirwa muchoto. Chikumbavhu chinozadzwa nesimbi yakagadzirwa muchimiro chakasimba, chinopisirwa kuti chinyunguduke, chinotonhodzwa, uye chozosanganiswa nevacheki.
Mashandisirwo eMatrix Body PDC Bits
Matrix body PDC bits anonyanya kushandiswa pakushandisa uku:
- Maumbirwo akapfava kusvika pakati nepakati akaomarara
- Vhoriyamu yakakwira
- Jecha rakawanda
- Mashandisirwo apo bit imwechete ichada kushandiswa kune akati wandei bit runs
Simbi Muviri PDC Bits
Mabhiti ePDC emuviri wesimbi ndeimwe yemhando dzemabhiti ePDC anonyanya kuzivikanwa. Mabhiti aya akasiyana nebhiti rematrix mukugadzirwa kwawo. Akagadzirwa nesimbi pachinzvimbo chesimbi inoshandiswa pamabhati ePDC emuviri wematrix. Akanaka kwazvo pakudzivirira kukanganiswa asi anogona kukanganiswa nekukukurwa kwevhu.
Zvidimbu zvesimbi zvePDC zvinoshandisa kucheka kwechidimbu ichi kupwanya dombo rachiri kuboora. Kazhinji zvinogara zvakagadzikana uye zvinogona kuboora nekumhanya kwakanyanya.
Zvidimbu izvi zvinogadzirwa nesimbi. Zvidimbu zvinogadzirwa nesimbi uye machira ekugadzira kuti zvigadzire muviri wechidimbu, uye mazino ekucheka nedanda zvinosungirirwa pairi. Zvidimbu zvesimbi zvePDC zvinogadzirwa zviri nyore kuita maumbirwo akaomarara nemagadzirirwo. Kugadzira magadzirirwo akaomarara kunobvumira mhando dzakasiyana dzezvidimbu zvekucheka uye magadzirirwo. Kusiyana kwezvidimbu zvekucheka kunogona kubatsira pakuchera matombo akasiyana.
Mashandisirwo eSimbi Body PDC Bits
Zvidimbu zvePDC zvemuviri wesimbi zvinobatsira muzvishandiso zvinosanganisira:
- Kuchera matombo eshale
- Nzvimbo dzakapfava dzematombo emabwe
- Kuboorwa nekukurumidza mu stratum
- Kuchera gasi rechisikigo
- Matsime akadzika
- Maitiro ekusagadzikana
