| Abstract: | In this paper,a self—adaptive autoregressive model is applied to predict the drilling trajectary of the directional and horizontal wells.This model needs few pa- rameters and can predict very quickly.Field data from cluster drilling of 9 wells prove that the model is of high accuracy.The average error of well deflection angle is less than 0.1° and the average absolute error of azimuth is less than 0. 5°. |

| Keywords: | directional wells predict drilling trajectary self—adaptive model |
