STUDY ON EVALUATIONS OF THE DRILLED FORMATION CHARACTERISTICS
实钻地层特性评估方法的研究

Based on the study of rock bit interaction, the physical models for inversion of the drilled formation characteristics are obtained. The computer program developed can be applied to calculate and plot the pore pressure, lithology and anisotropy of the formations. The results obtained by running the program are in coincidence with the data from oil field, and verification of the above models is shown.
