Pamusoro 5 Tricone Drill Bit Kutadza Kukanganisa Kuchera Kubudirira.

1. Flow Passage Erosion, Perforation, uye Nozzle Drop-off

Zvikonzero zvinokonzeresa kukukurwa kwemugero wekuyerera uye kuputika ndezvinotevera:

-Kushandiswa kwemaviri nozzle musanganiswa;

- Yakawandisa inlet kuyerera velocity mumuromo;

- Yakakwirira-density madhaka ane yakakwira yakasimba-chikamu chemukati;

-Kushandisa pulse nozzle zvimiro zvisingaenderane neyedu zvidimbu zvetricone drill.

Nekuda kweakasarudzika mamiriro e geological mune mamwe maoiri uye maitiro ekuchera anoshandiswa, iron ore poda inowedzerwa kudhaka system. Kushandisa maviri maviri nozzle musanganiswa uye pulse nozzle zvimiro zvinowedzera hydraulic maitiro, ayo anokuvadza zvakanyanyachidimbu chetricone drillnzira dzinoyerera. Mamiriro ezvinhu aya anoratidzawo kuti kweduchidimbu chetricone drill nzira dzekuyerera dzinogona kusazadzisa zvizere zvinodiwa nevashandisi.

Kushandisa zvekare mhino dzechinyakare kana kushandisa dzisiri dzemazuva ese dzisingaenderane nezvakatsanangurwa nekambani yedu zvinogona kukudza gaka pabendekete remuromo, kugadzira eddy currents inotungamira mukuboborwa kwechigaro chenozzle. Ichi zvakare chimwe chezvikonzero zvekutanga zvekutadza kwenozzle.

Zviitiko zvekudonha kweNozzle zvakanyanya kuNorth America neShengli Oilfield. Zvikonzero zvikuru zvinosanganisira nzira dzekuisa dzisina kufanira panguva yekumisikidza nozzle kana kuvapo kwezvinhu zvekune dzimwe nyika zvinokonzeresa kubuda kwemadhaka. Kana rin'i yekuvharisa kana rin'i yekuvharisa yakukurwa yodonha, muromo unova usingadzoreki uye unogona kuwira mutsime.

2. Koni kana Koni Tip Kudonha mutsime

Pave nemakumi maviri neimwe nyaya dzemakoni kana makoni akadonha mumatsime, kunyanya muSichuan, Shengli, neKaramay oilfields.

Chikonzero chekutadza kwecone tip ndeye eccentric kutenderera kwechibooreso, kana kusakara kwakanyanya pamazino ekoni nemagrooves, zvichitungamira mukutsemuka kwemuromo uye kunotevera kwedhaka kupinda mumabhengi, zvichikonzera kutadza. Eccentric kutenderera kwedrill bitinogona kukonzerwa ne:

-Abrasive maumbirwo kana maumbirwo ekuchinja anokonzera mukati memutsara mazino kupfeka kana kuputsika;

- Kusarudzwa kwebhiti kusiri iko, gomba rezasi risina kuchena, kana chibhorani chisina kurongeka;

- High lateral mauto kana composite kuchera nedhaka mota.

Kukundikana kwekoni kunokonzerwa ne:

- Tip kutyoka nekunonoka kutsika, zvichikonzera kutakura jenari kupfeka uye kukiya kukuvara kwegorofu, zvichitungamira mukuburitswa kwesimbi bhora uye kudonha kwekoni;

- Kudhiraivha zvine hukasha nemadhaka motors, zvichikonzera kutakura chisimbiso kutadza kana kupfeka kwekunamira, izvo zvinotungamira kudonha kwekoni;

-Abnormal working conditions of the drill bitdownhole.

3. Kutyoka kweZino, Kudonha kweZino, uye Mazino Akatsetseka

Zvikonzero zvikuru zvekutsemuka kwemazino zvinosanganisira:

- Debris pazasi petsime;

-Kusarudzika bhiti kusarudzwa kana kuumbwa kwakaoma;

- Bit bounce kana buri rezasi risina kuchena.

Kudonha kwemazino kunonyanya kuitika nekuda kwekunyanya kupfeka paganda rekoni, kuderedza simba rekubata remazino. Kudzika kwemazino kwave kucherechedzwa mumatsime egeothermal muDalian neTianjin, kunyanya nekuda kwekuoma uye kubvongodza maumbirwo.

4. Kubereka Kukundikana

Zvikonzero zvekutadza kupfeka kwekunamira nekuda kwekuwanda kwenzvimbo inotakura mutoro zvinosanganisira:

- Yakakwira WN kukosha, kushandiswa kweimwe-bend mota, zvichikonzera akakwira lateral masimba pane dhiri dhiri;

- Mamiriro ekugadzira kana zvinhu zvekune dzimwe nyika pagomba rezasi, zvichikonzera kubvongodza uye kukanganisa mitoro;

-Eccentric kutenderera kweiyo bit, inotungamira kune kusaenzana kutakura mutoro.

Kukasira kutadza kutakura zvisimbiso kunokonzerwa nekudzikira kwakadzika kwe tembiricha kana kushandiswa zvishoma mumatsime akatsemuka. Kupisa kwefrictional kunogadzirwa nekubatana pakati pekoni kumashure uye tsime, zvichiita kuti zvisimbiso zverabha zvipise uye zvidzikise nguva isati yakwana.

5. Thread Connection Fracture uye Kuputsika Kwegumbo

Drill mabhiti ane tambo yakatsemuka yekubatanidza kazhinji anosangana neizvi nekuda kwekusarongeka kwe makeup kana kuwandisa torque, izvo zvinogadzira kushushikana kunotangisa uye kuparadzira kutsemuka, pakupedzisira zvichikonzera kukanganisa kubatana kweshinda.

Kutyoka kwegumbo kunowanzoitika panguva yekushushikana mupfungwa padyo neinotakura magazini mudzi, zvakanyanya nekuda kwe:

-Isina kufanira kana isingaenderane bit box makeup, iyo inosimbisa koni uye inoshandisa yakawandisa torque;

- Mamiriro ekugadzira anokonzera kusimba kwedhayamita kupfeka, kuderedza simba rejenari;

- Abnormal stress pane drill bit.
