摘      要：The optimization of methods for the quantitative evaluation of risks in drilling engineering is an effective means to ensure safety in situations where high temperature and high pressure blocks are *** such a context,this study analyzes the complexity of the drilled wells in such *** is shown that phenomena such as well kick,loss,circulation,and sticking,are related to the imbalance of wellbore pressure.A method for risk quantitative evaluation is proposed *** method is used to evaluate the risk for 9 drilled *** comparing the predictions of the method with actual historical data related to these wells,it is found that the coincidence rate is about 95%.
