Matrix Lub Cev PDC Core Bit
Tsim kom muaj ROP siab dua hauv kev sib sib zog nqus thiab sib zog ua haujlwm, PDC xyaum me ntsis ib txwm xyaum los ntawm hauv av mus rau hauv qab ncaj qha nrog tsawg lossis txawm tias ib zaug khiav, txuag ntau qhov kev siv sijhawm thiab tus nqi.
Sib txawv los ntawm tricone ntsis, PDC laum me ntsis khiav nrog WOB qis dua tab sis siab dua RPM, yog li nws feem ntau ua haujlwm nrog lub tshuab qis qis kom tuaj yeem nrawm nrawm.
Kev ua tau zoo ntawm PDC laum me ntsis nyob ntawm ntau ntawm PDC cov tshuab txiav, peb muab cov kev daws teeb meem tshwj xeeb rau qhov xav tau tshwj xeeb ntawm cov ntawv sib txawv.
Taw qhia:
Nws tiv taus yaig nrog kev pab lub neej ntev uas tuaj yeem txhim kho kev ua kom zoo thiab txuag nqi.
Nta
1.Drilling hauv nruab nrab mus rau qhov nyuaj:Lub laum me muaj qhov nruab nrab thiab luv parabolic crowns, riam-tis hniav thiab nruab nrab-siab ntom ntom ntaub ntaub. Nws tuaj yeem tau txais kev nrawm nrawm dua hauv kev tsim nrog lub zog qis qis thiab me me ntawm kev txhuam.
2.Txoj Cai Txiav Cov Hniav: 13 hli txawv teb chaws txiav cov hniav tshwj xeeb txhim kho lub peev xwm los laum nyuaj interlayer.
3.Txoj Kev Ntsuas Siab: Qhov siv cov khoom siv dag zog siab txhim kho qhov hnav tsis kam ntawm qhov ntsuas thiab ua rau nws muaj lub neej ntev nrog cov khoom siv laum.
