Ukusetyenziswa kunye noxilongo lweFault of Tricone Bits

1. Ukukhetha kancinci

Xa ubhobhoza ubunzulu obahlukeneyo kwaye udibana ne-abrasiveness yokwakheka eyahluka-hlukeneyo, kubalulekile ukukhetha i-tricone bit echanekileyo ngokusekelwe kwinjongo yokomba (umzekelo, ukucocwa kwequla, ukugrumba iplagi, okanye ukugrunjwa kwendlela). Kumacandelo aphezulu angenzulwanga, khetha ai-tricone rotary drill bitngesantya esiphezulu sokomba oomatshini kunye namazinyo avuleke kakhulu. Kumacandelwana anzulu, apho ukuqhutywa kokwenziwa kuncipha, iqondo lobushushu lequla liyenyuka, kwaye ixesha lokutshintshwa kwesuntswana liyenyuka, khetha kancinane ubomi obude, ukumelana nobushushu obuphezulu, kunye nokunganyangeki okuqinileyo, okufana nei-tungsten carbide i-tricone drill bitokanye aI-TCI ye-tricone bit. Ukongeza i-wedge-shaped or conical teeth kwi-bit kunokuphucula ukusebenza kwayo kwezoqoqosho, ngakumbi xa usebenza nayoamasuntswana okomba borewellokanye kwizicelo zemigodi, apho ukuqina kubalulekile.

2. Ukusetyenziswa kweBit Tricone

Nangona ukukhetha isuntswana elifanelekileyo kubalulekile, ukusetyenziswa ngokufanelekileyo kubaluleke ngokufanayo. Nangona imodeli ye-bit echanekileyo, ukusetyenziswa okungafanelekanga kunokukhokelela kwimiphumo enganelisiyo.

(1) Ukuhlolwa kweBit kunye nokwamkelwa:

Oku kubandakanya ukujonga inkangeleko yesuntswana, ukuqinisekisa ukuhambelana nezixhobo zokuphatha kancinci, imilomo, kunye nezitshixo zombhobho. Ngaphambi kokuba uqhube isuntswana emngxunyeni, khangela ngesandla ukujikeleza kwe-tricone kwaye urekhode iinkcukacha ezifanelekileyo, kubandakanywa imodeli ye-bit, umenzi, ibakala lensimbi, inombolo yomngxuma wamanzi kunye nobukhulu, kunye nohlobo lokudibanisa intambo, ukuqinisekisa ukuba ihambelana ne-adapter. Ukuba usebenzisa i-metal seal drilling bit, jonga kabini inkqubo yokutywina ukunqanda imiba yokulahleka kwamanzi.

(2) Ukuphathwa kweBit:

Sebenzisa isixhobo esichanekileyo sokuphatha i-bit, khusela i-bit, sebenzisa i-lubricant yentambo, kwaye uyiqinise ngokuhambelana ne-torque ekhuthazwayo, uqinisekisa ukuba i-bit iqhotyoshelwe ngokukhuselekileyo (qinisekisa ukuba umkhono wokunxiba ufakwe ngokulandelelana okuchanekileyo okanye indawo).

(3) Ukubaleka kunye nokuReaming:

Lawula isantya esithotyiweyo ngokusebenzisa izithinteli zokuvuthela, iintloko zecasing, amacandelo ancitshisiweyo edayamitha, amacandelo okomba umkhombandlela, okanye amacandelo e-dogleg. Yehlisa isuntswana ngokutyibilikayo ukunqanda umbhobho obambekayo okanye ukubambeka kancinci. Kumacandelo amade, jikeleza ngokwezigaba ukuthintela ukuncamathela, ukuvuza, okanye ukulahleka kokujikeleza. Qinisekisa ukuba impompo isebenza ngokuqhelekileyo phambi kokuba ubuyisele kwakhona. Ai-tricone rock bitisoloko ilungele ezi meko ngenxa yokukwazi kwayo ukujongana noluhlu lweefomati.

(4) Ukuphonononga emazantsi:

Xa usondela ezantsi, jonga ubunzima kwibit (WOB) kunye netorque. Ukuba i-WOB kunye ne-torque yonyuka, ibonisa ukudibanisa nezantsi okanye ukusika okuqokelelweyo. Kuphephe ukuthoba ngobumfama intwana okanye ukuphonononga ezantsi, njengoko kunokuvala imingxuma yamanzi. Ukuba kukho ukusika okanye nayiphi na into ephazamisayo, phakamisa umtya wokubhobhoza, uqalise ngokukhawuleza impompo, uqinisekise ukusebenza ngokufanelekileyo kwempompo, uze ucoce umzantsi ngelixa udibanisa. Soloko uyiqala kwangoko impompo kwaye uyimise kade. Ukuba ugrumba kwiindlela ezinzima,faka amasuntswana okugaya izinyoinokusebenza ngakumbi.

(5) Ukugrumba okanye ukuPlaga:

Emva kokuba ufikile ezantsi, hlamba iqula ukuze ucoce umngxuma phambi kokomba. Sebenzisa i-WOB ephantsi, isantya esisezantsi sokujikeleza, izinga lokuhamba okuphezulu, kunye ne-torque ephantsi ukugcina iimeko zemingxuma. Ngelixa ujikeleza kwaye ujikeleza umtya we-drill, ukuwuhambisa phezulu naphantsi kunceda ukucoca i-bit. Lawula i-WOB ukunqanda ukonakalisa isuntswana. Ukubeka iliso kwinguqu yoxinzelelo lwempompo ukunqanda ukuvaleka kwemilomo. Xa udibana ne-stick-slip okanye utshintsho oluphawulekayo lwe-torque, lungisa isantya, unciphise i-WOB, sebenzisa isantya esiphantsi, kwaye uzinzise i-torque. Ukuba usebenzisa intambo yombane esebenza ngamandla, yehlisa isantya sokuhamba; ukuba usebenzisa i-drill string engenamandla, nyusa izinga lokuhamba. Kukho umahluko ekuthelekiseni iWOB kunye nesantya. Isantya esiphezulu kunye ne-WOB ephantsi zilungele ukubunjwa okuthambileyo, ngelixa i-WOB ephezulu kunye nesantya esiphantsi singcono kwiifom ezinzima. Xa usebenza nge-abrasive formations,amasuntswana e-tricone yezinyo eligidiweyoinokubonelela ngentsebenzo engcono.

3. Tricone Bit Fault Diagnosis

(1) Ukucutheka kancinci:

Xa ugrumba kwiifom ezinobunzima obuphezulu, i-bit ingaba namava okuncipha. Ukusebenza kwe-bit kunye ne-stabilizer yokusika i-wellbore ibonisa i-torque eyongeziweyo kwitafile ejikelezayo okanye i-top drive, i-drilling ebambelele, isantya sokujikeleza esingazinzanga (esiguquguqukayo ngokuhamba kwexesha), kwaye akukho ukwanda kwe-torque yokubhoboza. Ukusetyenziswa kwe-WOB ephantsi kunye nesantya esisezantsi akukunciphisi ukugrumba okuxingileyo. Ukuba akukho nto ivaliweyo emva kokuphakamisa i-bit kunye nokumisa impompo, kwaye akukho zixhobo ezinkulu zamatye ezibonwayo kwi-shaker, kunokugqitywa ukuba i-bit iyancipha. Lo mbandela uxhaphakile xa usebenzisaiicones ezintathu zokubhola kwiimeko ezinzima.

(2) Ukubanjwa kancinci:

Ukuba kukho ukwanda kwe-torque (umzekelo, ukunyuka komthwalo kwitafile ejikelezayo okanye kwi-top drive, u-drilling obambekayo ngamaxesha, iinguqu ezinkulu kwimveliso yenkqubo yamandla, okanye ingxolo ye-injini engaqhelekanga), kudibaniswa nexesha lokusetyenziswa kwe-bit kunye neemeko zokwakheka, kubonisa ukuba i-bit ingabanjwa. Ujikelezo olukhawulezileyo kunye nokufunyanwa kancinci kufuneka kwenziwe. Ai-tricone rock bitngamanye amaxesha unokujongana nalo mba, ngakumbi kulwalwa oluqinileyo.

(3) Ukulahleka kwamazinyo:

Ukuba kukho ukwanda kwe-torque kwitafile ejikelezayo okanye kwi-top drive, kwaye xa itafile ejikelezayo okanye i-top drive imisiwe, i-bit iqala ukuguquka, ngokunyathela okuqinileyo, ukuguquguquka kweenaliti kwisalathisi sobunzima, kuncitshiswe kakhulu okanye akukho myinge wokungena, okanye utshintsho lwesikhokelo xa uphakamisa umtya wokubhobhoza, ukulahleka kwamazinyo kungenzeka. Oku kuphawuleka ngakumbi kumaqula anzulu, kwaye kufuneka kujongwe kwaye kutshintshwe kwangethuba ukuphepha umonakalo ongakumbi. Kwiimeko ezinjalo, izinyo lokugaya kwimigodi okanye i-TCI drill bits enokuqina okongeziweyo kunokunceda ukunciphisa ukuguga.

Qaphela: Kwimeko yokuxinga okanye ukugrumba ngesiquphe, intwana kufuneka itsalwe kwaye ihlolwe okanye itshintshwe ngokukhawuleza. Kuphephe ukukhangela ezantsi kwiimeko ezinjalo ukuthintela ukulahleka kwamazinyo ngakumbi.

Enyanisweni, abavelisi abahlukeneyo, ubukhulu, kunye neemodeli ze-tricone bits, nangona zisetyenziswe phantsi kweeparitha ezicetyiswayo, zinexesha elikhuselekileyo lokusebenza. Logama nje kungekho msebenzi ungafanelekanga wenziwayo ngeli xesha, intwana ikhuselekile ngokubanzi. Kungenjalo, kufuneka iphathwe ngobunono. Kubalulekile ukukhetha phakathifaka amasuntswana okugaya izinyookanyeamasuntswana e-tricone yezinyo eligidiweyokuxhomekeke kulwakhiwo oluthile ukuqinisekisa ukusebenza kakuhle.
