Watermelon String Mill
Watermelon hlua khau yog ib qho ntawm cov cuab yeej milling hauv kev ua haujlwm sab. Nws yog siv los kho cov casing, reaming thiab qhib cov channel. Nws feem ntau yog siv tam sim tom qab qhib qhov rais. Lub milling ntug (ua hauj lwm cheeb tsam) ntawm lub watermelon zeb hu rau lub borehole phab ntsa, thiab qhov kawg ntawm txhua ntug yog tsim los ua lub khob hliav qab. Thaum lub qhov rais qhib, cov txiv tsawb zeb tuaj yeem ua kom ntev lub qhov rais los ntawm sab saum toj thiab tshem tawm cov scaling thiab burrs sab laug ntawm cov yeeb nkab phab ntsa thaum pib txiav.

Pilot zeb
Pilot zeb yog tsim rau milling casing, liner, teb khau los yog loj ID tubing. Cov hniav txiav hnav khaub ncaws nrog cov khoom siv tungsten carbide siab ua rau Petrozhr pilot mills tuaj yeem ua tiav kev nkag mus sai nrog tsawg hnav.Qhov me me thiab curled txiav cov khib nyiab yog yooj yim tshem tawm. Thiab tus tsav kawg yog siv los ua kom ruaj khov hauv ID ntawm cov khoom uas raug milled.
