USING THE LOGGING INFORMATION OPTIMIZATION MUD DESIGN OF WELL DRILLING.

This paper analyses as affecting the various factors of borehole stability to go on.We make the feasibility scheme of using the logging information optimization mud design of well drilling.How to prevent project accident such as lost circulation,borehole caving,well collapse had been discussed,think good choose mud density and understanding the direction and size of stress apply correctly the project of well drilling is the crucial place that solves these problems.
