Laum me ntsis daim ntawv thov cov lus qhia
1 ntsis xaiv
1.Thov nyeem cov lus piav qhia lithology thiab cov ntaub ntawv me ntsis ntawm cov qhov dej uas nyob ib sab ua tib zoo, thiab txheeb xyuas cov yam ntxwv tsim.
2.Xaiv hom tsim nyog raws li lithology.
2 Kev npaj ua ntej drilling
1.Tshuaj xyuas me ntsis yav dhau los rau lub cev puas tsuaj, poob cutters lossis inserts thiab lwm yam. Ua kom tsis muaj cov khib nyiab ntawm lub pob tw, thiab ntxuav lub qhov hauv qab yog tias tsim nyog.
2.Bit yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj kev puas tsuaj cutters thiab cov khoom tawv.
3.Kuaj xyuas seb puas muaj kev puas tsuaj ntawm me ntsis cuttes thiab yog tias muaj cov khoom txawv teb chaws hauv qhov me me.
4.Kuaj xyuas seb qhov kev txhim kho nozzle puas ua tau raws li qhov yuav tsum tau ua, thiab hloov cov nozzles yog tias tsim nyog.
3 Kos qhov me ntsis
1.Clean me ntsis xov thiab siv roj rau cov xov.
2.Raws lub breaker mus rau me ntsis, txo txoj hlua xyaum mus rau tus pin thiab koom nrog cov xov.
3.Ntawm qhov me ntsis thiab tawg hauv lub teb bushing, thiab ua kom me ntsis kom pom zoo torque.
4 Tripping hauv
1. Tshem tawm lub breaker thiab ua tib zoo txo qis me ntsis los ntawm cov khoom siv lub taub hau kom tsis txhob ua rau nws puas.
2.Shrinkage, lub xub pwg nyom, dogleg thiab lub rooj zaum tseem ceeb ntawm borehole yuav tsum ceev faj thaum me ntsis los ntawm qhov khoob.
3. Pib lub twj tso kua mis thiab lub voj voog drilling dej los ntxuav lub qhov taub thaum xyaum mus rau qhov taw tes txog 30 meters mus rau hauv qab ntawm lub qhov, thiab tig lub laum txoj hlua ntawm qhov ceev tsis tshaj 60rpm.
4.Txuas hauv qab li ib nrab 'meter'.Ci rau 5 mus rau 10 feeb nrog dej puv.
5 Reaming
1.Reaming ntev seem ntawm undergauge qhov tsis pom zoo.
2.Yog tias yuav tsum tau ua haujlwm reaming, nws tau pom zoo tias qhov kev ua haujlwm reaming yuav tsum tau ua nrog qhov siab tshaj plaws ntawm kev khiav, tshwj xeeb qhov hnyav ntawm me ntsis tsis tshaj 90N / mm (inch), rotary ceev tsis tshaj 60 rpm qhov twg daig tau ntsib thaum tripping hauv.
6 ntsis break-in
1.Overusing zaub seev thaum me ntsis approch bottomhole.Yog hais tias WOB thiab torque nce, uas qhia tau hais tias me ntsis tau attived ntawm bottomhole.Siv tsis ntau tshaj 90N / mm, hnyav -on = ntsis thiab 40to 60rpm los tsim lub bottomhole qauv yam tsawg ib nrab 'meter'.
2.Bit break-in tiav thiab yuav tsum tau kho RPM kom tau txais kev pom zoo drilling parameter ua ke.
3.Drilling tsis hloov kho yuav tsum raug xaiv nyob rau hauv cov kev txwv ntawm qhov kev pom zoo tsis xa mus rau kev pom zoo drilling tsis optimization txoj kev.
