AB - 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.
