Abstract:

This paper analyzes the complexity and its reason of Xishanyao and Badaowan coal seam wellbore in Tuha Basin,and emphatically discusses the mechanism of the coal seam wellbore unstability. The result shows that coal seam wellbore unstability is a synthetic effect caused by such factors as physics,chemistry,mechanics and machinery.

Key words: Tuha Basin, Xishanyao, Badawan, Coal seam, Hole sloughing prevention, Hole damage, Hole .stabilization
