Zvinhu Zvinokanganisa Kuchera Hunhu uye Kumhanya

1. Sezvo drill bit speed yekuboora komputa yakapetwa kaviri yegiya II regiyo yekuchera, uye kanoda kuita kana iyo yegiya I, zviri nyore kuwedzera zvakanyanya ROP.

2.The high rotational speed of compound drilling inokodzera kutema maitiro ePDC bit mukugadzira shear.

3.Wellbore trajectory iri nyore. Kubatanidza kudhirowa kwakananga uye kutsvedza kudhiraivha kwechinguvana shanduko, zviri nyore kudzora iyo dogleg angle uye kuve nechokwadi chekuchengetedzwa kwepasi.

4.The drilling tool structure iri nyore nyore. Panguva yekuchera mukomboni, dhiri yekuchera inowanzo <100-120kN, uye zvinodiwa pakuchera zvinogona kupedzwa nemakororo mashoma kana asina, uye mukana wekunamira wakaderedzwa zvakanyanya.

5. Iyo yepamusoro-inoshanda PDC drill bit inobatana neiyo simba rekuchera chishandiso kuchera matsime, iyo inodzivirira kutadza kwekutanga kweiyo koni inotakura pakukurumidza uye haikonzereki kurasikirwa kwekoni.

Pesvedzero yeDrilling Parameters pane Drilling Quality Speed

Munguva yekuchera, pesvedzero yemaparamendi ekuchera pakati pezvinhu zvinodzoreka pakumhanya kwekuchera hazvigone kufuratirwa, senge: bit mhando, bit nozzle dhayamita, bit simba remvura, bit pressure, kukurumidza, pombi yekumanikidza, kutama, nezvimwe. iyo nyaya yemamwe mamiriro echinangwa, iyo ROP inowanzowedzerwa nekudzora kudhirowa kudhiraivha, kutenderera kumhanya, kupomba kumanikidza uye kutamiswa.

Pesvedzero yeKuchera Fluid paKuchera Hunhu uye Kumhanya

Drilling fluid iropa rekuchera, saka kuita kwemvura yekuchera kwakakosha pakuchera. Zvinhu zvikuru zvinokanganisa ROP ndeye viscosity yemvura yekuchera, kuwanda kwemvura yekuchera uye yakasimba mukati memvura yekuchera. Tichifunga nezvenyaya yekuti mushonga wekurapa unoshandiswa mune iripo yakadzika tsime fluid system yakapfuma mune chromium ion uye mamwe heavy metal ion ane simba guru pane zvakatipoteredza, zvinokurudzirwa kudzidza uye kushandisa nharaunda yakadzika tsime yekuchera mvura. sisitimu yekuvandudza silicate drilling fluid system parizvino inoshandiswa mune diki diki muChina, Synthetic basic drilling system kuti igadzire yakadzika tsime kuchengetedza kuchera mvura inoteedzana inokodzera mamiriro ejoloji uye einjiniya enzvimbo yega yega yekuchera.
