Kudzivirira uye kurapwa kwekuchera kudonha kunamatira

Nekuda kwekusashanda zvakanaka kwemvura yekuchera, yakawandisa kusefa kunonyorovesa kuumbwa uye kusunungurwa. Kana kuti shale yakanyudzwa muchikamu chetsime ine yakawandisa dip Angle inowedzera, ichipaza mugomba uye ichikonzera kunamira kuchera.

Zviratidzo zvekuputsika kwemadziro etsime:

1.Yakadonha panguva yekuchera

2.Tsime yakadonha panguva yekuchera

3.Tsime rakadonha richiboora

4.Reaming yakasiyana

Kudzivirira kudonha kwemadziro:

1. Shandisa anti-collapsing drilling fluid kana kuti drilling system inoenderana nekuumbwa, zvakakodzera kunatsiridza density uye viscosity yemvura yekuchera, kunyatso kudzora kurasikirwa kwemvura, uye kugadzirisa dombo rekutakura.

2. Kuchera munzvimbo dzinoputika, vasati vapinda muShahejie maitiro, mvura yekuchera inofanira kuwedzerwa nezvinhu zvakakwana zvekudzivirira-kudonha maererano nezvinodiwa zvekugadzira, uye zvinyorwa zvinofanira kusvika kusvika 3%.

3. Kuita kwemvura yekuchera kunofanira kugadzikana uye haigoni kurapwa zvakanyanya.

4. Panguva yekuchera, kuwedzera kwepombi kunowedzera, uremu hwakarembera hunoderera, chigadziro chekuchera chakanamatira, uye kudzoka kwechitsime kunoderedzwa kana kuti tafura imwe chete inotenderera inosunungurwa. Kana pombi yekuchera yakadzoserwa zvakakomba, pombi yekuchera inofanira kumira kana kubatana, mudziyo wekuchera unofanirwa kusimudzwa kune yakajairika tsime chikamu, uye nzira yekuyerera nayo inogamuchirwa.

5. Kuchera munzvimbo inovuza, mvura yekuchera yakawanda mune shoma kunze, kumisa kucheresa kutenderera kwekutarisa, kuvuza kunodarika 5 m³/h, kana mukati nekubuda chete, kunofanirwa kucherwa nekukasira, kudhirowa kweannular kusingaperi kwemvura yekuchera, haifanirwe kuvhurika. pombi pakati. Kana iyo yekuchera mvura isina kukwana, inogona kuzadzwa nemvura kuedza kuburitsa mudziyo wekuchera.

6. Dzivisa kutenderera-kutenderera, kazhinji shandura chinzvimbo, uye edza kudzivirira chikamu chetsime chiri nyore kudonha nekudonha.

7. Kuchera kunofanira kuramba kuchizadzwa nemvura yekuchera kuchengetedza kudzvanywa kwembiru yemvura. Kana kuchera kwakamira, hakuna kuoma kudhonza kunze. Mushure mokunge mudziyo wekuchera wadzikiswa kune chikamu chetsime uye pombi yakazarurwa kazhinji nekutama kuduku, kutenderera kunowedzera zvishoma nezvishoma.

8. Tanga kuchera nekumhanya kwakaderera pasina kuburitsa piston.

9. Dzora kukurumidza kwekuchera, hapana kuoma kwakaoma kana kupikisa, simudza chigadziro chekuchera kune chikamu chemutsime wakatsetseka, uye shandisa imwe punch. Nzira mbiri kusvika nhatu.

Kurapa kwe shaft wall kudonha:

Mushure mekuputsika kwechibhorani, panogona kunge kune mamiriro maviri, imwe ndeyokuti kutenderera kunogona kuva kuduku, uye imwe ndeyokuti kutenderera hakugoni kusimbiswa zvachose.

1. Kana iwe uchikwanisa kutenderera nekutamisa kudiki, haufanirwe kurasikirwa netariro iyi, asi unofanirwa kudzora chiyero chekutanga chekuyerera kwekunze uye kubuda kunze. Mushure mokunge kutenderera kwakagadzikana, zvishoma nezvishoma kuwedzera viscosity uye kugera kwemvura yekuchera kuti iwedzere simba rayo rekutakura jecha, uye zvishoma nezvishoma kuwedzera kuyerera kwekuedza kuunza dombo rakaputsika kumusoro. Mushure mekunge danho iri raitwa, kunyangwe kana chibooreso chinonamira chekuyamwa chikaitika, chinoitwawo.

2. Kana gomba rakanamira rakaumbwa nekudonha kwe limestone uye dolomite, uye chikamu chakaputsika chetsime chisina kureba, unogona kufunga nezvekupomba inhibitory hydrochloric acid kuti usunungure yakanamatira.

3. Nhanho inotevera ndeye milling reverse. Mukugadzirwa kwakapfava, zvinokurudzirwa kushandisa chigayo chakareba chebhari, kana kushandisa chigayo chakareba chebhari nekoni yechirume kana pfumo rehove, kuitira kuti kugayo nekudzosera kumashure kunogona kupedzwa panguva imwe kukurumidza kufambira mberi. Mukugadzirwa kwakaoma, zvinokurudzirwa kudzikisa kureba kwechubhu yekasi uye kuderedza zvikanganiso mukugayo. Kana uchikuya kucenterizer, zvinokurudzirwa kuisa chirongo kuti usunungure yakanamatira, nokuti chokwadi chakawanda chakaratidza kuti pane zvishoma kuunganidza jecha pazasi pecentralizer, uye hazvifanirwe kugaya iyo stabilizer.
