Zida Zapamwamba za Downhole Milling

Kufotokozera Kwachidule:

Zida zophera nsomba zimagwiritsidwa ntchito popera nsomba ndi zinthu zina zogwetsera pansi, kuyeretsa khoma (bowo la khoma) zinyalala kapena kukonza posungira. Mfundo yake ndi pogaya nsomba kukhala zinyalala mozungulira ndi kukakamizidwa kwa chingwe chobowola ndi tungsten carbide yomwe imawotchedwa pagawo lodulira la mphero, ndipo zinyalala zimatha kubwezeredwa pansi ndi madzi obowola.
Mitundu yambiri ya zida zophera ndizofala m'mapangidwe, pomwe malinga ndi mawonekedwe osiyanasiyana a nsomba, mbali zodulira zimafunikira. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimatha kukonzedwa mkati, kunja ndi kumapeto kwa zida za mphero.
Pambuyo pakupanga kwatsopano komanso kudzikundikira kwaukadaulo m'zaka zaposachedwa, akumana ndi zosowa zenizeni za makasitomala ochokera ku China ndi kunja chifukwa cha magwiridwe antchito odalirika. Kupatulapo mitundu ndi makulidwe omwe atchulidwa pazotsatirazi, timalandilanso kupanga molingana ndi mawonekedwe apadera omwe angakwaniritse zosowa za kasitomala.

Tengani chitsanzo cha nsapato za mphero:

Thupi lalikulu limagwiritsa ntchito zitsulo zazitsulo zogwira ntchito kwambiri (4145H) kuti zitsimikizire kuti zimagwira ntchito bwino komanso mogwira mtima pansi pa zovuta zosiyanasiyana zoboola komanso kuthamanga kwa rotary. Pakadali pano, timatengera zitsulo zapamwamba za tungsten carbide kuti tikwaniritse mphero mwachangu. Stabilizer ndi siketi yakunja ya junk mphero ndi taper mphero zitha kupangidwa ngati pakufunika.

Amagwiritsidwa ntchito pogaya pang'ono, kondomu, choyezera m'mimba mwake, mano olimbana, chitoliro chochapira, polumikizira zida zobowolera, zida zapampopi zakuya, zopakira, zogawa madzi ndi zida zina zazitali.
Petrozhr junk mphero amapezeka mumitundu yosiyanasiyana komanso ma geometries. Uinjiniya wathu wapamwamba wa mphero komanso wowotcherera wodziwa bwino amaonetsetsa kuti mpheroyo imakhala yokhazikika komanso yokhazikika pamphero iliyonse yazakudya.
