The invention discloses an interpretation method for well logging during drilling. The method includes the steps of well logging information collection, stratigraphic model construction, exploration drilling, measurement while drilling, simulation value acquisition and stratigraphic model adjustment. The interpretation method for well logging during drilling has the advantages that a geologic model obtained according to the method better conforms to practical geological conditions and is capable of not only providing reliable real-time bases for geosteering during exploration drilling but also achieving the interpretation and evaluation purpose after drilling to obtain more accurate and reliable well logging interpretation results, so that the requirements of current exploration and development, particularly horizontal well exploration drilling can be met.
