          Abstract:
          Because of the complicated geological features, the borehole destabilization seriously influencs the drilling engineering in the terrestrial formation, northeastern Sichuan. The rock mechanics theory is used to study the core experimental data, testing data and calibration log data in this area. Established are the models to calculate and construct the parameters profile including rock elastic parameters, earth stress, three formation pressures and the safety window of drilling mud density. The research also confirmed the main geological factors influencing the borehole destabilization in this area are the complicated and variable lithology, developed fractures and multisuits of vertical pressure system, etc. Moreover, this technology has been used in the drilling wells and obtains a good result, which provides an important technical support for the borehole destabilization evaluation in the terrestrial formation in northeastern Sichuan.
