PDM Drill (downhole Tsav)
Lub downhole Tsav yog ib hom downhole fais fab cuab yeej siv lub zog los ntawm cov kua thiab ces txhais cov kua siab mus rau txhua yam zog. Thaum lub zog cov kua dej ntws mus rau hauv lub hydraulic lub cev muaj zog, qhov sib txawv ntawm qhov sib txawv ntawm qhov nkag thiab qhov hluav taws xob ntawm lub cev muaj zog tuaj yeem tig lub rotor hauv stator, muab qhov tsim nyog torque thiab ceev rau lub laum me ntsis rau drilling. Cov ntsia hlau laum cov cuab yeej yog tsim rau ntsug, directional thiab kab rov tav qhov dej.
