Abstract Lost circulation and borehole collapse often occurred in petroleum drilling.The key is that the three pressure profiles which can maintain borehole stability couldn’t been prodicted.The mechanics analysis software is successfully developed for borehole stability after plenty of theory reseach and experiment. The laboratory measurement and well logging data analysis method are introduced to get formation strength and mechanical parameter which are necessary in the software. The prediction with the software is applied to drilling in Nanhai oilfield，and the results are satisfactory.

Key words： formation pressure profile prediction method application effect
