Ntxiv ib lub desander rau koj cov av nkos
Tshawb xyuas cov av nkos txhua ob peb meters
Yam khoom:
👉 Mud Pumps & Circulation Systems →/mud{0}}pump/
5
Tsis yog Drill Bit Xaiv
Ib lub laum me ntsis sib phim rau qhov tsim tsis raug nkim sijhawm thiab roj.
Xaiv cov khoom raws li tsim
Drag Bit→ soft av nplaum
Tricone Ib→ Mixed formations
DTH Ib→ hard rock
Qhov Opener→ nthuav borehole ua ntej casing
Cov cuab yeej pom zoo:
👉 DTH rauj & khawm khoom →/dth-rauj/
6
Tsis muaj zog lossis tsis sib haum xeeb Cua Compressor
Cua ntim thiab cua siab yog lub plawv ntawm DTH drilling. Ntau tus neeg ua haujlwm saib xyuas qhov xav tau ntawm compressor.
Cov teeb meem huab cua
Lub siab poob tom qab 80-120 meters
Cuttings tsis tuaj yeem nqa tawm
Drill hlua tau daig
Kev nkag mus qeeb hauv pob zeb
Cov lus qhia kom raug Compressor
13–17 bar → qhov dej ntiav
17–25 bar → tob pob zeb qhov dej
900-1500 cfm → kev tu lub qhov zoo
