Abstract

Reasonable hole configuration can avoid drilling incident. Traditional hole configuration design method can't show the necessary cementing point with complex lithology. In this paper, firstly, the four pressure calculation models and the value basis of hole configuration design coefficient and value range were introduced. Secondly, the restriction conditions for safely drilling in naked hole section were introduced. Finally, A hole configuration was designed by considering leakage pressure and changing coefficients. During drilling, there is no incident, Which can prove that the design method and coefficient range is reasonable and effective.
