Kushandisa uye Kukanganisa Kuongororwa kweTricone Bits

1. Bit Selection

Pakuchera kusvika pakadzika kwakasiyana uye uchisangana nekuumbwa kwakasiyana-siyana, zvakakosha kuti usarudze chidimbu chakakodzera chetricone zvichienderana nechinangwa chekuchera (semuenzaniso, kucheneswa kwetsime, kudhirowa kweplug, kana kudhirowa kwenzira). Muchikamu chepamusoro chetsime chisina kudzika, sarudza atrione rotary drill bitine high mechanical drilling speed uye mazino akaparadzana zvakanyanya. Kune zvikamu zvakadzika, uko kudhirowa kwekugadzira kunodzikira, tembiricha yemutsime inokwira, uye nguva yekutsiviwa kunowedzera, sarudza zvishoma nehupenyu hurefu, kushivirira kwepamusoro, uye kusapfeka kwakasimba, sengetungsten carbide tricone drill bitkana aTCI trione zvishoma. Kuwedzera mazino akaita wedge kana conical kune bhiti kunogona kuvandudza hupfumi hwayo, kunyanya kana uchishanda nayoborewell drilling bitskana mumigodhi, uko kusimba kwakakosha.

2. Tricone Bit Kushandisa

Nepo kusarudza bhiti rakakodzera kwakakosha, kushandiswa kwakakodzera kwakakosha zvakaenzana. Kunyangwe neiyo chaiyo bit modhi, kushandiswa zvisina kunaka kunogona kutungamirira kumigumisiro isingafadzi.

(1) Bit Kuongorora uye Kugamuchirwa:

Izvi zvinosanganisira kutarisa kutaridzika kweiyo bhiti, kuve nechokwadi kuenderana nebit kubata maturusi, nozzles, uye nozzle wrenches. Usati wamhanyisa bhiti mugomba, tarisa nemaoko kutenderera kwetricone uye rekodha ruzivo rwakakodzera, kusanganisira bit modhi, mugadziri, giredhi resimbi, nhamba yegomba remvura uye saizi, uye yekubatanidza tambo mhando, kuve nechokwadi kuti inofanana neadapter. Kana iwe uri kushandisa simbi seal drilling bit, kaviri-tarisa yekuisa chisimbiso kuti udzivise kurasikirwa kwemvura.

(2) Bit Handling:

Shandisa iyo chaiyo bit yekubata chishandiso, chengetedza bhiti, isa shinda yekuzora, uye woisimbisa zvinoenderana neinokurudzirwa torque, uchisimbisa bhiti rakanamirwa zvakachengetedzeka (ona kuti sleeve yekupfeka yakaiswa mukutevedzana kwakaringana kana chinzvimbo).

(3) Kumhanya mukati uye Kuongorora:

Dzora kumhanya kwekudzikisa kuburikidza nezvinodzivirira kuvhuvhuta, misoro yemakesi, zvikamu zvakaderedzwa zvedhayamita, zvikamu zvekuchera, kana zvikamu zvedogleg. Dzikisa zvishoma zvishoma kuti udzivise pombi yakanamira kana kuti bit jamming. Pazvikamu zvirefu, tenderera mumatanho kudzivirira kunamira, kubuda, kana kurasikirwa kwekutenderera. Ita shuwa kuti pombi iri kushanda zvakajairika isati yatangazve. Atrione rock bitinowanzoenderana nemamiriro ezvinhu aya nekuda kwekugona kwayo kubata huwandu hwemaumbirwo.

(4) Kuongorora Pazasi:

Paunosvika pasi, tarisa huremu pabit (WOB) uye torque. Kana WOB uye torque zvichiwedzera, inoratidza kubata nepasi kana kuunganidza kucheka. Dzivisa upofu kudzikisa bhiti kana kuongorora pasi, sezvo inogona kuvhara makomba emvura. Kana paine zvicherwa kana chipi chinovhiringidza, simudza tambo yekubooresa, zvishoma nezvishoma tanga pombi, chengetedza kushanda kwepombi kwakaringana, wobva wachenesa pasi uchigadzira kubatanidza. Gara uchitanga pombi nekukurumidza uye kuimisa nguva yapera. Kana iwe uchichera kuburikidza nemaitiro akaoma,isa zvimedu zvekubooresa zinozvingava zvinobudirira.

(5) Kuchera kana kubatanidza:

Kana wasvika pasi, geza tsime kuti uchenese gomba usati waboora. Shandisa yakaderera WOB, yakaderera kutenderera kumhanya, yakakwira kuyerera, uye yakaderera torque kuchengetedza maburi mamiriro. Paunenge uchitenderera uye uchitenderedza tambo yekubooresa, kuifambisa kumusoro nekudzika kunobatsira kuchenesa bhiti. Dzora WOB kudzivirira kukuvadza chidimbu. Monitor pombi pressure inoshanduka kudzivirira kuvharika kwenozzle. Paunenge uchisangana netsvimbo-inotsvedza kana yakakosha kusiyanisa torque, gadzirisa kumhanya, kuderedza WOB, shandisa yakaderera kumhanya, uye kudzikamisa torque. Kana ukashandisa chibooreso tambo, kuderedza kuyerera kweyero; kana ukashandisa chibooreso chine tambo isina simba, wedzera mwero wekuyerera. Pane misiyano mukufananidza WOB uye kumhanya. Kumhanya kwepamusoro uye kuderera kweWOB kwakakodzera kuumbwa kwakapfava, nepo WOB yakakwira uye yakaderera kumhanya zviri nani kune yakaoma maumbirwo. Paunenge uchishanda neabrasive formations,milled zino trione bitsinogona kupa kushanda kuri nani.

3. Tricone Bit Fault Diagnosis

(1) Kuderera zvishoma:

Pakuchera kuburikidza nemaumbirwo ane abrasiveness yakakwirira, bhiti rinogona kusangana nekuderera. Kuita kweiyo bit uye stabilizer kucheka tsime kunoratidza yakawedzera torque patafura inotenderera kana yepamusoro dhiraivha, yakanamatira kudhiraivha, isina kugadzikana inotenderera kumhanya (inochinja nekufamba kwenguva), uye hapana kuwedzera kwekuchera torque. Iko kushandiswa kweWOB yakaderera uye yakaderera kumhanya haideredze kunamira kuchera. Kana pasina kuvhara mushure mekusimudza bhiti uye kumisa pombi, uye pasina matombo makuru ematombo anoonekwa pane shaker, zvinogona kugumiswa kuti chidimbu chiri kuderera. Iyi nyaya inowanzoitika pakushandisamatatu makoni anoboorera zvimedu mumamiriro ezvinhu akaoma.

(2) Bit Seizure:

Kana paine kuwedzera kwe torque (semuenzaniso, kuwedzera mutoro patafura inotenderera kana dhiraivha yepamusoro, kudhirowa kwakanamatira nguva nenguva, misiyano mikuru mukubuda kwesimba remagetsi, kana ruzha rweinjini isina kujairika), yakasanganiswa nenguva yekushandiswa kwebit uye mamiriro ekuumbwa, zvinoratidza kuti bhiti rinogona kubatwa. Kutenderera nekukasira uye kudzoreredza zvishoma kunofanira kuitwa. Atrione rock bitdzimwe nguva inogona kutarisana nenyaya iyi, kunyanya mukugadzirwa kwedombo rakaoma.

(3) Kubuda Zino:

Kana pane kuwedzera kwe torque patafura inotenderera kana yepamusoro motokari, uye kana tafura ye rotary kana dhiraivha yepamusoro ichimiswa, bhiti rinotanga kutendeuka, nekuchera kwakasimba kwakanamatira, kuchinja kwetsono-kufanana nekuchinja kwechiratidzo chehuremu, kuderedzwa zvakanyanya kana kuti pasina chiyero chekupinda, kana kuchinja kwekutungamira pakusimudza tambo yekuchera, kurasikirwa kwezino kungave kwakaitika. Izvi zvinonyanya kucherechedzwa mumatsime akadzika, uye zvinofanirwa kutariswa nekutsiviwa nekufamba kwenguva kudzivirira kumwe kukanganisa. Muzviitiko zvakadaro, zvimedu zvemazino zvakagayiwa zvemigodhi kana TCI drill bits zvine kusimba kwakawedzerwa zvinogona kubatsira kuderedza kusakara.

Cherechedzo: Kana paine chero yakanamatira kana kucheneruka mamiriro ekuchera, bhiti rinofanirwa kudhonzwa kunze nekuongororwa kana kutsiviwa nekukasira. Dzivisa kuongorora pasi mumamiriro ezvinhu akadaro kudzivirira kuwedzera kuparara kwezino.

Mukuita, vagadziri vakasiyana, saizi, uye mhando dze trione bits, kunyangwe kana yakashandiswa pasi peyakakurudzirwa paramita, ine yakachengeteka yekushanda nguva. Chero bedzi pasina kushanda kusina kunaka kunoitika mukati menguva ino, bhiti racho rinowanzo chengeteka. Zvikasadaro, inofanira kubatwa nokungwarira. Zvakakosha kusarudza pakatiisa zvimedu zvekubooresa zinokanamilled zino trione bitszvichienderana nekuumbwa kwakananga kuti ive nechokwadi chekushanda kwakakwana.
