IADC Tricone Bit Classification Codes System

IADC Tricone Bit Classification Codes System

Hangata lichate tsa IADC cone drilling bit classification li sebelisoa ho khetha bonyane bo molemo ka ho fetisisa bakeng sa ts'ebeliso e itseng. Lichate tsena li na le likotoana tse fumanehang ho tsoa ho baetsi ba bane ba etelletseng pele ba likotoana. Li-bits li arotsoe ho latela khoutu ea Mokhatlo oa Machaba oa Li-Drilling Contractors (IADC). Boemo ba karolo e 'ngoe le e' ngoe ka chateng bo hlalosoa ka linomoro tse tharo le sebopeho se le seng. Tatellano ea litlhaku tsa linomoro e hlalosa "Series, Type and Features" ea bit. Sebopeho se eketsehileng se hlalosa likarolo tse eketsehileng tsa moralo.

IADC KHOUTU TŠEBELETSO

Nomoro ea Pele:

1, 2 and 3 designate Steel Tooth Bits, with 1 for soft, 2 for medium and 3 for hard formations.

4, 5, 6, 7 and 8 designate Tungsten Carbide Insert Bits for varying formation hardness with 4 being the softest and 8 the hardest.

Nomoro ea Bobeli:

1, 2, 3 and 4 help further breakdown the formation with1 being the softest and 4 the hardest.Nomoro ea Boraro:

Nomoro ena e tla arola karoloana ho latela mofuta oa ho beha / tiiso le ts'ireletso e khethehileng ea li-gauge ka tsela e latelang:

1.Standard bula bering rolara bit

2.Standard bula bearing bit bakeng sa ho cheka moea feela

3.Standard bula bearing bit e nang le ts'ireletso ea gauge e hlalosoang e le

carbide e kenya serethe sa khoune.

4.Roller tiisitsoe bering bit

5.Roller e tiisitsoeng ka ho beha bit e nang le carbide e kenyang serethe sa khoune.

6.Journal e tiisitsoeng e bering bit

7.Journal e tiisitsoeng e bering bit e kenyang carbide seretheng sa khoune.

Popeho ea "bonolo" "bohareng" le "thata" ke likarolo tse pharaletseng haholo tsa letamo la jeoloji le ntseng le phunyeletsoa. Ka kakaretso, mefuta ea majoe ka har'a sehlopha ka seng e ka hlalosoa ka tsela e latelang:

Meetso e bonolo ke letsopa le lehlabathe le sa kopanngoeng.

Tsena li ka chekoa ka WOB e batlang e le tlase (pakeng tsa 3000-5000 lbs/in of bit diameter) le RPM e phahameng (125-250 RPM).

Litefiso tse kholo tsa phallo li lokela ho sebelisoa ho hloekisa lesoba ka katleho kaha ROP e lebelletsoe ho ba holimo.

Leha ho le joalo, litefiso tse feteletseng tsa phallo li ka baka ho hlatsuoa (hlahloba hore na lipeipi tsa ho phunya li hlatsuoa). Litefiso tsa phallo ea 500-800 gpm lia khothaletsoa.

Joalo ka mefuta eohle ea li-bit, boiphihlelo ba lehae bo bapala karolo e kholo ho etsa qeto ea li-parameter tsa ts'ebetso.

Meetso e mahareng e ka kenyelletsa shale, gypsum, shaley lime, lehlabathe le siltstone. 

Ka kakaretso WOB e tlase e lekane (3000-6000 lbs/in ea biti ea bophara).

Lebelo le phahameng la rotary le ka sebelisoa ka li-shales empa tjhoko e hloka sekhahla se fokolang (100-150 RPM).

Majoe a lehlabathe a bonolo a ka boela a phunngoa ka har'a mekhahlelo ena.

Hape ho khothaletsoa litefiso tse phahameng tsa phallo bakeng sa ho hloekisa masoba

Libopeho tse thata li ka kenyelletsa lejoe la mokoetla, anhydrite, lejoe le thata la lehlabathe le nang le li-quartic streaks le dolomite.

Tsena ke majoe a matla a phahameng a ho hatella 'me a na le lintho tse senyang.

Ho ka 'na ha hlokahala WOB e phahameng (mohlala, pakeng tsa 6000-10000 lbs/in of bitidiameter.

Ka kakaretso lebelo la rotary le sebelisoa butle (40-100 RPM) ho thusa ketso ea ho sila / ho pshatla.

Mekhahlelo e thata haholo ea quartzite kapa chert e cheka hantle ka ho kenya likotoana tsa daemane ho sebelisa RPM e phahameng le WOB e tlase. Litefiso tsa phallo hangata ha li bohlokoa mefuteng e joalo.
