Yakakwana Nhungamiro yeTricone Drill Bit Sarudzo uye Kushandisa

Mukuchera rotary, iyodrill bitinoshanda sechombo chikuru chekupwanya maumbirwo ematombo. Hunhu hwebhiti uye kuenderana kwayo nemhando yekugadzira, zvivakwa zvedombo, uye mamiriro ekuchera anokanganisa kumhanya kwekuchera. Kusarudza yakaringana bhiti mhando uye kudhirowa paramita zvichienderana nemamiriro ekuumbwa kwakakosha pakuvandudza kudhirowa nekudzikisa mitengo. Kuchera kwakadzika-tsime kunosangana nemaitiro akawanda uye marudzi ematombo ane akasiyana zvivakwa, kugadziradrill bitkusarudza basa rakaoma.

1. Empirical Bit Sarudzo nzira

Iyo inozivikanwawo seMunda Drilling Data Method, iyi inzira inoshanda uye inoshandiswa zvakanyanya pakati penyanzvi dzemunda. Inotsamira pakuongorora data kubva kumatsime ari padyo munzvimbo imwe chete, ichitarisa kumhando diki dzakawana yakanyanya kucherwa uye avhareji mwero wekupinda pasi pemamiriro akafanana ejologi uye kudzika. Iyi nzira iri nyore, inoshanda, uye yakanyatsokodzera matunhu ane maumbirwo akafanana.

2. Reference-Based Bit Selection Method

Kuti ukunde zvipimo zvemaitiro ehunyanzvi, nzira iyi inosanganisira acoustic yekutema dhata sechiratidzo chisina kunanga chekugadzira, ichisimbisa huchokwadi hwesainzi. Inozivikanwa se "Reference Method," inoda vatengesi vashoma kuti vaenzanise maparamendi ekugadzira anotorwa kubva kune acoustic kutema neakamisikidzwa bit matemplate matemplate, achigonesa kurudziro chaiyo.

3. Kuenzana Mukana Bit SelectionNzira

Iyi nzira inotevera nzira yakarongeka:

• Tora dhizaini yekugadzira data kuburikidza nekuyedza kana nzira dzekufungidzira.
• Shandisa ongororo yenhamba pane yakaunganidzwa dombo data kuti uone avhareji yekuboora kugona (Kd) uye chiyero chikanganiso (S) chega chega chimiro.
• Iine IADC kodhi bhiti yekusarudza chati, enzanisa dhizaini yekugonesa nhanho yekuona akakodzera mabhii mabhiti ega ega geological kuumbwa.

4. Yakakurudzirwa Drilling Parameters yeZvose Formations

Kushanda kwakanyanya kweadrill bitinotsamira pakusarudza iyo chaiyo bhiti mhando uye kushandisa yakakodzera dhiri paramita.

5. Drillability Profile uye Bit Selection yePuguang Formation

Kushandisa geological uye matanda data kubva mumatsime munharaunda yePuguang, bit performance yakaongororwa uye yakakamurwa ne geological layers uye borehole sizes kuburikidza ne "Drill Bit Technical Efficiency Index" (JX = VL = avhareji yemechani yekupinda mwero × bit footage).

• Maumbirwo uye Lithology Mbiri: Ruzivo rwemazita, ukobvu, uye akasangana nemhando dzematombo munzvimbo yePuguang.
• Drillability Profile uye Inokurudzirwa Bit Sarudzo: Inoisa Class mafomati neIADC makodhi zvichienderana nedhill kugona mazinga.
• Empirical Bit Selection Recommendations: Zvichienderana nedunhu bhiti rekushandisa data, izvi zvinopa zvinokurudzirwa bit zvigadziriso zveakajairwa saizi.
• Zvikumbiro zveUinjiniya Parameter: Inoverengera huremu hwakakwana-pa-bit (WOB), RPM, hydraulic simba index, uye chikumbaridzo WOB yakavakirwa padombo drill.

6. Nhungamiro yeOptimal Drill Bit Selection uye Kushandisa

(a) Sarudzo Yakavakirwa paLithology uye Kudhirowa kugona: Kudhirowa bhiti kusarudzwa kunofanira kunyanya kufunga nezvekugadzira lithology uye kugona kudhiraivha kupatsanura, negadziridzo zvichienderana neiyo lithological profiles yakasangana panguva yekuchera.

(b) General Recommendations forPDC Bits: Kazhinji,PDC zvikamuanokodzera zvinyoro-kusvika-pakati maumbirwo.

• Kune maumbirwo akapfava ane high plasticity, shandisa mabits ane hombe-diameterPDCvanocheka uye highcutter kuratidzwa kuti iwedzere kushanda kwedombo-kupwanya.
• Kune epakati-akaoma maumbirwo ane yakaderera plasticity, sarudza mabits ane diki-diameter PDC cutters uye yakaderera kuratidzwa kudzivirira kutyora kwekucheka uye kuwedzera hupenyu hwematurusi.

(c) Kugadziridza Maparamendi ekuchera Kubva paBit Structure uye Formation Conditions: Rongedza parameters-senge WOB, RPM, uye hydraulic simba-zvichienderana neiyo bhiti mamiriro uye magadzirirwo mamiriro, uye ona kuti anoramba ari mukati mekurudziro mitsara.

(d). Sarudzo yeNzira Nekudzika Kwemvura uye Chimiro:

• Kune maumbirwo akadzika, peya PDC mabheti ane downhole motors kukwidziridza yakakwira RPM kugona.
• Kune yepakati-yakadzika, yakakura-dhayamita yakaboora maapplication, wedzera WOB uye kuderedza RPM sezvakakodzera kukwirisa kudhirowa kwakanaka.
