Tilmaamaha dalbashada qaniinyada

1 xoogaa xul ah

1. Fadlan si taxadar leh u akhri sharaxaada lithology-ga iyo xogaha ceelasha ku xiga, iyo falanqaynta sifooyinka samaynta.

2.Doorashada nooca habboon ee waafaqsan lithology.

2 Diyaarinta ka hor inta aan la qodin

1. Iska hubi in yar oo hore u dhaawacantay jidhka, gooyayaasha lumay ama wax la galiyay iwm. Hubi in aanay jirin wax qashinka ah oo ku yaala daloosha badhida, oo nadiifi godka hoose haddii loo baahdo.

2.Bit waa in si taxadar leh loo maareeyaa si aysan waxyeelo u gaarin gooyayaasha iyo walxaha adag.

3. Hubi haddii ay jiraan wax dhaawac ah oo ku yimaadda qashinka yar iyo haddii ay jiraan wax shisheeye ah oo ku jira qashinka.

4. Hubi haddii ku rakibida biibiile ay buuxinayso shuruudaha, oo beddel nozzles haddii loo baahdo.

3 Calaamadaynta xoogaa

1.Nadiifi dunta yar oo dufan mari dunta.

2. Ku hafi jabiyaha xoogaa, hoos u dhig xadhigga biinanka oo geli dunta.

3. Ka hel qaybta iyo jabiyaha gudaha baadiyaha wareegta ah, oo ka samee inta lagu talinayo torque.

4 Soo gal

1. Ka saar jabiyaha oo si taxadir leh u yara hoos u sii dhex mari aaladda madaxa ceelka si aanay waxyeelo u geysan.

2.Xoojinta, garabka, eeyaha iyo kursiga muhiimka ah ee ceelka riigga ah waa in ay taxaddaraan marka la qaniino dalool bannaan.

3.Bilow bamka iyo dareeraha qodista wareegga si aad u dhaqdo daloolka barida marka la qodayo meel qiyaastii 30 mitir ka xigta godka, oo ku wareeji xadhigga daloolista xawaarihiisa hoose oo aan ka badnayn 60rpm

4.U dhowow xagga hoose qiyaastii nus mitir.Wareeg 5 ilaa 10 daqiiqadood oo leh qulqul buuxa.

5 Reaming

1.Reaming qaybaha dhaadheer ee godka hoose laguma talinayo.

2.Haddii hawlgalka dib-u-dejinta ay lagama maarmaan tahay, waxaa si xoog leh loogu talinayaa in hawlgalka dib-u-celinta lagu sameeyo wareegga wareegga ugu sarreeya, miisaan gaar ah oo aan ka badnayn 90N/mm (dhexroor), xawaaraha wareegga ah ee aan ka badnayn 60 rpm halkaasoo uu ku xayiran yahay markii uu dhacayay. gudaha

6 xoogaa jaban

1.Aaladaha bandhiga oo si xad dhaaf ah u isticmaala marka ay qaniinto godka hoose.Haddii WOB iyo torque-gu ay kordhaan, taasi waxay muujinaysaa in waxoogaa ay guntiga dhiisha iskaga dhigeen. Isticmaal wax aan ka badnayn 90N/mm, miisaan -on = bit iyo 40 to 60rpm si aad u dejiso qaabka godka hoose ugu yaraan nus mitir.

2.Bit break-in waa la dhammeeyay waana in la hagaajiyaa RPM si loo helo isku darka cabbirka qodista ugu wanaagsan.

3. hagaajinta cabbirrada qodista waa in lagu doortaa xadka cabbirada lagu taliyey ee tixraaca cabbiraadaha qodista ee lagu taliyey habka hagaajinta.
