ENGINEERING RISK ASSESSMENT METHOD FOR UNDRILLED STRATA BASED ON DRILLING CONSTRUCTION PREVIEW

ABSTRACT
With the development of the oil industry, the accuracy of the conventional well structure design method will be lower and lower. In order to ensure the smooth progress of drilling construction, this paper proposes a risk assessment method for the formation be drilled based on the equivalent drilling fluid density matrix, which reduces the use of empirical coefficients in the well structure design and realizes the fine design of the well structure.
KEYWORDS
risk assessment of strata to be drilled, circulation drilling, drilling fluid circulation equivalent density
