Top 5 Tricone Drill Bit Failures Ukuchaphazela ngokuSebenza ngokuSebenzayo.

1. Ukhukuliseko lwePasiji eHambayo, ukuNgqobhoza, kunye nokuLahlwa kweNozzle

Ezona zizathu ziphambili zokhukuliseko lwendlela yokuhamba kunye nokugqobhoza zezi zilandelayo:

- Ukusetyenziswa kwemibhobho emibini yendibaniselwano;

- Isantya sokungena ngokugqithisileyo kwi-nozzle;

- Udaka olunoxinano oluphezulu olunomxholo ophezulu wesigaba esiqinileyo;

-Ukusetyenziswa kolwakhiwo lombhobho wepulse olungahambelaniyo nolwethu i-tricone drill bits.

Ngenxa yeemeko ezizodwa ze-geological kwezinye iindawo zeoli kunye neenkqubo zokugaya ezisetyenzisiweyo, i-iron ore powder yongezwa kwinkqubo yodaka. Ukusebenzisa imidibaniso yemilomo emibini kunye nolwakhiwo lombhobho wepulse kwandisa impembelelo yehydraulic, eyonakalisa kakhului-tricone drill bitiipaseji zokuhamba. Le meko ikwatyhila ukuba wethui-tricone drill bit iipaseji zokuhamba zisenokunganeli ngokupheleleyo iimfuno ezikhethekileyo zabasebenzisi.

Ukusebenzisa kwakhona imilomo emidala okanye ukusebenzisa imilomo engekho mgangathweni engahambelaniyo neenkcukacha zenkampani yethu kunokwandisa isithuba esikhoyo kwigxalaba lombhobho, yenze imisinga edidayo ekhokelela ekugqobhozeni kwesitulo somlomo. Oku kukwangomnye woonobangela abaphambili bokusilela kwemibhobho.

Izehlo zokulahla umbhobho zigxile kakhulu kuMntla Merika naseShengli Oilfield. Izizathu eziphambili ziquka iindlela zokufakela ezingafanelekanga ngexesha lokunyuka kwe-nozzle okanye ubukho bezinto zangaphandle ezibangela ukuvuza kodaka. Nje ukuba umsesane wokutywina okanye umsesane wogcino ukhukulisekile kwaye uwe, umlomo awuthinteleki kwaye unokuwela equleni.

2. ICone okanye iCone Tip Ukuwisa kwiQula

Kubekho iimeko ezingama-21 zeecones okanye iingcebiso zecone eziwela emaquleni, ngakumbi eSichuan, eShengli, naseKaramay oilfields.

Unobangela wokungaphumeleli kwencam yecone kukujikeleziswa kwe-eccentric ye-drill bit, okanye ukunxitywa okuqatha kumazinyo e-cone kunye ne-grooves, ekhokelela ekuqhekekeni kwencam kunye nokungena kodaka okulandelayo kwiibheringi, kubangele ukusilela. Ukujikeleza kwe-Eccentric kwei-drill bitingabangelwa:

- Ukwakheka kwe-Abrasive okanye ukuguqulwa kokwakheka okubangela ukuba amazinyo angaphakathi kumqolo aguge okanye aphuke;

- Ukukhetha ibhiti ngokungafanelekanga, umngxuma ongezantsi ongacocekanga, okanye umngxuma ongaphantsi ongaqhelekanga;

- Amandla asemacaleni aphezulu xa kugrunjwa okuhlanganisiweyo ngenjini yodaka.

Ukusilela kokulahla ikhowuni kubangwa:

- Ukwaphuka kwengcebiso ngokulibaziseka ukukhubeka, okukhokelela ekunxibeni kwejenali kunye nomonakalo wokutshixa, okukhokelela ekukhululweni kwebhola yentsimbi kunye nokuwa kwekhowuni;

- Ukugrumba okukrakra ngeenjini zodaka, okukhokelela ekungaphumeleli kwetywina okanye ukunxiba okuncamathelayo, okukhokelela ekuweni kwecone;

- Iimeko zokusebenza ezingaqhelekanga ze i-drill bitumngxuma ezantsi.

3. Ukuqhawuka kwezinyo, ukuwisa izinyo, kunye namazinyo acaba

Oonobangela abaphambili bokuqhawuka kwamazinyo ziquka:

- Inkunkuma emazantsi equla;

- Ukukhethwa kwebhithi engafanelekanga okanye ukwakheka okuqinileyo;

- Ibhit gxuma okanye umngxuma ongezantsi ongacocekanga.

Ukuwa kwezinyo kwenzeka ikakhulu ngenxa yokuguga okugqithisileyo kwiqokobhe le-cone, ukunciphisa amandla okubamba amazinyo. Ukucandwa kwamazinyo kuye kwabonwa kumaqula e-geothermal e-Dalian nase-Tianjin, ikakhulu ngenxa yokwakheka okuqinileyo kunye ne-abrasive.

4. Ukuthwala Ukusilela

Izinto ezibangela ukusilela kokuncamathelisa ngenxa yomthwalo ogqithisiweyo wendawo uquka:

- Amaxabiso aphezulu e-WN, ukusetyenziswa kwe-motor-bend enye, okubangelwa amandla aphezulu asecaleni kwi-drill bit;

- Iimeko zokuqulunqa okanye izinto zangaphandle kumngxuma ongezantsi, obangela i-bit bounce kunye nemithwalo yempembelelo;

- Ujikelezo lwe-Eccentric yentwana, ekhokelela kumthwalo ongalinganiyo wokuthwala.

Ukusilela kwangethuba kokuzala amatywina kungenxa yobushushu obuphezulu bemingxuma okanye ukusetyenziswa kancinci kumaqula atenxileyo. Ubushushu befrictional benziwa kukudibana phakathi kwecone back and wellbore, nto leyo ebangela amatywina erabha afudumale kwaye athobeke phambi kwexesha.

5. Ukuqhawuka koQhagamshelwano lwemisonto kunye nokuqhekeka komlenze

Amasuntswana okucoca ngoqhagamshelo lwentambo eqhekekileyo ngokuqhelekileyo afumana oku ngenxa yokungalungiswanga kakuhle okanye itorque egqithisileyo, edala uxinzelelo oluthi luqalise kwaye lusasaze iintanda, ekugqibeleni lubangele ukusilela konxibelelwano lwentambo.

Ukwaphuka komlenze ngokuqhelekileyo kwenzeka kuxinzelelo loxinzelelo kufutshane nengcambu yejenali, ngokuyintloko ngenxa:

-I-makeup yebhokisi engafanelekanga okanye engahambelaniyo, egxininisa i-cone kwaye isebenzise i-torque egqithisileyo;

- Iimeko zokwakheka ezibangela ukunxitywa kwedayamitha enzima, ukunciphisa amandla ejenali;

- Uxinzelelo olungaqhelekanga kwi-drill bit.
