Clastic rock horizontal well track adjusting method based on LWD resistivity logging

The invention relates to the technical field of tracking an oil layer while drilling of a horizontal well, in particular to a clastic rock horizontal well trajectory adjusting method based on LWD resistivity logging, which comprises the following steps: calculating TZYZ by using GR and RT numerical values of a target interval and upper and lower surrounding rocks, and making a cross plot by using data of a curve of the TZYZ and a curve of the RT so as to determine discrimination boundaries of the target interval, the upper surrounding rocks and the lower surrounding rocks. A drill bit adjustment response mechanism for controlling a horizontal well tracking trajectory is formulated according to the discrimination boundaries of a target layer, an upper surrounding rock and a lower surrounding rock; in the drilling process, the drill bit direction is controlled in real time according to a drill bit adjustment response mechanism and adjustment factor number data calculated in real time, the scheme is simple and e
