Hlau Lub Cev PDC Laum Ntsis
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.

Hlau Lub Cev PDC Cov Khoom Teeb ROP Cov Ntaub Ntawv Thaum Drilling
hauv Sichuan Suav.
HNUB NYOOG
Txhawm rau txhawm rau txo tus nqi ntawm PDC Ntshuam me me los ntawm Smith thiab Halliburton, Suav tsim khoom muab lawv tus kheej tsim PDC Bit rau qhov dej zoo los hloov Smith Bits.
DAWS
Txhawm rau kom ua tiav ROP zoo dua, DeepFast muab nws tus kheej tsim Steel Lub cev PDC Ntsis 12 1/4 "DFS1905U kom tau txais ROP siab dua.
XAUS
Nws teev cov ntaub ntawv ROP tshiab ntawm 22.18 m/h.
Nws muaj ROP zoo dua li Smith Bit thiab Halliburton hauv cheeb tsam no.
Txheej txheem cej luam
Hauv Sichuan ntawm Tuam Tshoj txoj kev tsim yog nruab nrab-nyuaj tab sis txhuam, Chuanqing West Drilling Company xav txhim kho kev nrawm thiab nws tshwj xeeb tshaj yog ua PDC kev ntsuas hauv SI005-X5 thiab $ I005-X6 qhov dej pib pib los ntawm kwv yees li 500 meters rau 12 1 /4 qhov.
