Abstract
The invention discloses a micro-rotating drilling method in directional drilling, a computer device and a readable storage medium. Including: acquiring rotation speed and torque and on-site drilling information; taking the rotation speed and the torque as a micro-rotating drilling state learning sample, taking the on-site drilling information as a second learning sample, inputting to a neural network control model for training, outputting a micro-rotating drilling algorithm for controlling the top drive; controlling the top drive with the micro-rotating drilling algorithm to achieve the micro-rotation operation. In the invention, an maximum torque and an maximum speed of the top drive can be continuously controlled during the operations such that the drill string can drive the drill tool to drill forward at a preset speed, static frictional resistance exerted on the drill string can be better eliminated.
