In view of the difficulty of obtaining the basic parameters of drilling deep and ultra-deep wells in complex areas, drilling engineers in China and abroad have used a large amount of formation information in logging data in recent years to conduct an in-depth study on the application of logging data in drilling engineering And promotion. This paper introduces the principle, method, field application and computer application software of using well logging data to calculate the mechanical parameters of formation rock, predicting the formation pressure, calculating the drillability of formation rock, extracting the basic data of drilling, selecting and predicting the bit drilling speed Development situation. Based on the feedback information in field application, the problems in research and application are pointed out, and the development trend of logging data in drilling engineering is also forecasted
