Geosteering method and apparatus, and storage medium

A geosteering method, comprising:

• acquiring first well trajectory information of a target well, and first geological information and second geological information of the target well, wherein the first geological information is geological information obtained by investigating a geology of a first designated geological attribute in a region corresponding to a first well trajectory, the first geological information comprises interface coordinate information of geological layer of at least one geological attribute, and the second geological information comprises interface coordinate information of geological layers of geological attributes of a reference well of the target well;
• determining, by using a plane where the first well trajectory is located as a steering profile, a geological structure line of a first class geological layer corresponding to the first geological information on the steering profile, and determining, by using the geological structure line of the first class geological layer as a reference and based on the second geological information, a geological structure line of a second class geological layer corresponding to the second geological information on the steering profile, so as to obtain a geosteering model of the target well, wherein the geological structure lines are intersecting lines between interfaces of the geological layers and the steering profile, and the second class geological layer is a geological layer with a geological attribute that is different from that of the first class geological layer;
• and
• using the geosteering model to perform geosteering on actual drilling of the target well.
