Key words:<\/strong> drilling problem, accident, wellbore instability, mechanical properties of rock, inelastic deformation zone, swell speed of wellbore.

This article focuses on the condition of wellbore instablility while drilling well at Vietsovpetro\u2019s offshore fields. The statistic and analysis of the wellbore stability time from moment opening the formation by drilling was revealed. Wellbore\u2019s swelling speed in the Lower Miocene Field \u00abWhite Tiger\u00bb was calculated. A comparison of the result analysis material by field report with calculation result is presented. In addition, the evaluation material of wellbore stability time by using the different drilling technology\u2019s are shown.<\/p>\n
