Abstract

A drilling method and a drilling apparatus are provided. In the method, the feature parameter of the stratum around the well, the feature parameter of the stratum in front of the drill bit, the preset drilling parameter, the preset trajectory parameter, the current pose of the drill bit and the current rate of penetration of the drill bit are obtained; the feature parameter of the reservoir in front of the drill bit is determined based on the feature parameter of the stratum around the well and the feature parameter of the stratum in front of the drill bit; the above parameters are inputted to the pre-trained drilling parameter modification model to obtain drilling trajectory parameter and drilling speed parameters; and the drilling direction and the rate of penetration are regulated based on the above parameters.
