2.Kusarudza mhando yakakodzera maererano ne lithology.

2 Kugadzirira usati wachera

1.Ongorora chidimbu chekare chekukuvara kwemuviri, kucheka kwekucheka kwakarasika kana kuisa nezvimwe. Iva nechokwadi kuti hapana chero junk pane buttom gole, uye chenesa gomba rezasi kana zvichidiwa.

2.Bit inofanira kubatwa nekuchenjerera kuitira kuti irege kukuvadza vanocheka uye zvinhu zvakaoma.

3.Check kana pane kukuvadzwa pane bit cuttes uye kana pane imwe nyika nyaya mukati me bit.

4.Check kana kuisa nozzle kunoenderana nezvinodiwa, uye kutsiva nozzles kana zvichidikanwa.

3 Kutara kumusoro

1.Clean bit threads woisa girizi pashinda.

2.Fit the breaker to the bit, dzikisa tambo yekuboora papini uye ubatanidze tambo.

3.Locate the bit and breaker in the rotary bushing, uye ita-up iyo bit kuti igamuchirwe torque.

4 Kupinda mukati

1.Bvisa muputsi uye unyatsodzikisa zvishoma kuburikidza nemudziyo wematsime kuitira kuti urege kukuvadza.

2.Shrinkage,shoulder,dogleg and key seat of borehole inofanira kungwarira kana yapinda nepaburi risina chinhu.

3.Tanga pombi uye cycle drilling fluid kuti ugeze buri repabuttom paunoboora kusvika pane imwe nzvimbo inenge 30 metres kusvika pasi pegomba, uye tenderedza tambo yekuboorera pa low speed isingadarike 60rpm.

4.Swedera pasi inenge hafu yemamita.Denderedzwa kwemaminetsi mashanu kusvika gumi nekuyerera kwakazara.

5 Kurangarira

1.Reaming yakareba zvikamu zvegomba re undergauge hazvikurudzirwi.

2.Kana basa rekudzorera richidikanwa, zvinokurudzirwa zvakasimba kuti basa rekudzorera riitwe nehupamhi hwekuyerera kweyero kutenderera, huremu hwakananga pabit husingapfuure 90N/mm (dhayamita), kasi yekutenderera isingapfuure 60 rpm apo yakanamatira payakagumburwa. mu.

6 Bit kupaza-mukati

1.Overusing kuratidza zviridzwa kana bit approch bottomhole.Kana iyo WOB uye torque zvichiwedzera, zvinoratidza kuti bit have attived at bottomhole.Shandisa isingadariki 90N/mm, huremu -on = bit uye 40to 60rpm kumisa pateni yepasi pehafu yemamita.

2.Bit break-in yapera uye inofanira kugadziriswa RPM kuti iwane optimal drilling parameter musanganiswa.

3.Drilling parameters kugadzirisa kunofanira kusarudzwa mukati memiganhu yemiganhu yakakurudzirwa inoreva kukurudzirwa kudhiraivha parameters optimization nzira.
