Madhiragidhi ekuchera ari pakati pezvishandiso zvekuchera zvinoshandiswa zvakanyanya mukuchera matsime emvura, kuongorora geology, migodhi, kuvaka, mapurojekiti egeothermal, uye HDD (Horizontal Directional Drilling). Nekuda kwechimiro chavo chiri nyore, kushanda zvakanaka, uye kushanda zvakanaka muzvikamu zvakapfava kusvika zvepakati, madhiragidhi ekuchera achiri sarudzo yakakurumbira kune vanogadzira dhiragi pasi rese.
KuChina Far Eastern Drilling, tinopa mhando dzakasiyana dzema "drag bits" akagadzirirwa mamiriro akasiyana e geology uye zvinodiwa pakuboorera. Chinyorwa chino chinopa mhando huru dzema "drag bits" zvichibva pachimiro chekucheka uye kuvakwa kwemuviri.
1. Kupatsanura neKucheka Maumbirwo
Tungsten Carbide Drag Bit (Tungsten Drag Bit)
Zvidimbu zvekudhonza zveTungsten zvinoshandisa tungsten carbide inserts yepamusoro-soro kana zvinhu zvakasimba sezvinhu zvekucheka. Zvidimbu izvi zvinozivikanwa ne:
Kudzivirira kupfeka kwakanaka
Kushanda kwekuchera kunodhura uye kunoshanda zvakanaka
Yakakodzera kuumbwa kwakapfava kusvika pakati nepakati
Inoshandiswa zvakanyanya mutsime remvura uye mukuchera mabhora epasi pevhu
PDC Dhonza Bit
Zvidimbu zvekudhonza zvePDC (Polycrystalline Diamond Compact) zvinoshandisa michina yekucheka madhaimani yakagadzirwa, zvichiita kuti kucheka kugare kwenguva refu uye kugoneka pakuboorwa.
Zvakanakira zvinosanganisira:
Kupinda kwepamusoro kwehuwandu hwevanhu
Hupenyu hwebasa hwakareba
Dziviriro iri nani yegeji
Mari yekuboora yakaderedzwa pamita imwe neimwe
Mabhiti ekudhonza ePDC anowanzo shandiswa mu:
Kuchera matsime emvura
Kuboorwa kwemhepo inopisa
Mapurojekiti eHDD
Kuongorora migodhi
Kuboora kwekuvaka
Danho rekudhonza Bit
Step Drag Bit ndeimwe yemadhizaini ePDC drag bit anozivikanwa zvikuru. Kurongeka kwayo kwekucheka kwakapinza kunovandudza kushanda zvakanaka kwekucheka uye kupinda kwekugadzira.
Zvimiro:
Chiito chekucheka nehasha
Kumhanya kwekuboora nekukurumidza
Kuchenesa maburi zvakanaka kwazvo
Yakakodzera ivhu, shale, sandstone, nezvimwe zvakapfava
Chevron Drag Bit
Zvidimbu zvekudhonza zvemhando yeChevron zvine blade rakaita seV rinobatsira kudzikamisa chidimbu ukuwo zvichivandudza kudzora kwakanangana.
Mashandisirwo anosanganisira:
Matsime emvura
Maburi emutyairi weHDD
Kuongorora kwezvepasi
Dhirowa Bit reMulti-Blade PDC
Zvichienderana nezvinodiwa pakuchera, madhiri ekudhonza ePDC anogona kugadzirwa ne:
Mapazi matatu
Mapazi mana
Mapazi mashanu
6 mashizha kana kupfuura
Mamwe mapanga anowanzo wedzera kugara kwenguva refu uye hunhu hwemaburi, nepo mapanga mashoma achiwanzoita kuti pave nekukasira kupinda.
2. Kupatsanurwa neBit Body Material
Kunze kwerudzi rwekucheka, madhibhiti ekudhonza anogonawo kurongwa zvichienderana nemaitiro ekugadzira muviri wedhibhiti.
Kanda Muviri Wekudhonza Bit
Zvidimbu zvekudhonza muviri zvinogadzirwa kuburikidza nemaitiro ekukanda nemazvo.
Zvakanakira:
Mutengo wakaderera wekugadzira
Sarudzo dzekugadzira dzinochinjika
Yakakodzera kushandiswa kwekuchera bhora kwetsika
Zvidimbu izvi zvinowanzo shandiswa apo kunyanya kukosha kwemari ndiko kunonyanya kukosha.
Kudhonza Muviri Wakagadzirwa
Zvidimbu zvekudhonza muviri zvakagadzirwa nesimbi yakagadzirwa, zvichiita kuti chimiro chive chakasimba uye chakasimba.
Zvakanakira:
Simba repamusoro remakanika
Kudzivirira mhedzisiro kuri nani
Hupenyu hwebasa hwakareba
Kuvimbika kwepamusoro mumamiriro ekuboorera akaomarara
Zvidimbu zvekudhonza zvakagadzirwa nemuviri zvakaumbwa zvinofarirwa pabasa rehunyanzvi rekuboorera uko kushanda nesimba uye kugara kwenguva refu zvakakosha.
3. Kusarudza Chidimbu Chekudhonza Chakakodzera
Kusarudza dhiraivha yakakodzera kunoenderana nezvinhu zvakati wandei:
Kuoma kwekugadzirwa
Nzira yekuboorera
Chiyero chinodiwa chekupinda
Dhayamita yegomba
Zvaunofanira kufunga nezvebhajeti
Kuti zvigadzirwe zvakapfava uye zviome zvishoma, tungsten drag bits ndiyo inonyanya kufarirwa. Kuti zviome zvakanaka uye kuti zviome kwenguva yakareba, PDC drag bits inowanzopa kushanda kwakanakisa.
Nezve Far Eastern Drilling
Weifang Far Eastern Machinery Co., Ltd. inonyanya kugadzira nekupa maturusi ekuboorera emhando yepamusoro, anosanganisira:
Zvidimbu zveTricone
PDC Bits
PDC Drag Bits
Zvidimbu zveHybrid
Zvivhuriso zveMaburi
Magadzirirwo eHDD
Zvishandiso Zvekuchera Dombo
Neruzivo rwemakore anopfuura gumi nemashanu muindasitiri uye vatengi munyika dzinopfuura makumi matatu, Far Eastern Drilling inoramba ichipa mhinduro dzakavimbika dzekuchera matsime emvura, geothermal, migodhi, kuongorora geology, HDD, kuvaka, uye mapurojekiti enheyo pasi rese.
Tibatei nhasi kuti muwane mhinduro yakakodzera yekudhonza bit pabasa renyu rinotevera rekuboorera.
