The fast sedimentation rate, complex lithology, and extensive development of interlayers make it difficult to identify the interlayers in sandy conglomerate reservoirs. In response to the problem of unclear identification of interlayers in the sandy conglomerate reservoirs of the Cretaceous Guyang Formation in the west of Hetao Basin. Based on the differences in logging responses of different rock types and physical properties, a comprehensive identification method for multiple logging parameters of interlayer is proposed, which is used to separately identify gravelly interlayer, argillaceous interlayer, calcareous interlayer, and physical property interlayer. Multiple types of interlayers are extensively developed in the research area, mainly consisting of gravelly and argillaceous interlayers. In the sedimentation of fan roots, a large number of gravelly interlayers are distributed, with a large thickness and quantity of interlayers; in the direction of the fan, the hydrodynamic force gradually weakens, causing a gradual decrease in the number of gravel interlayers and a gradual decrease in the overall development of the interlayers; continuing towards the fan edge, there is an increase in the sedimentation of sandy and muddy sediments, with more development of argillaceous interlayers and an increasing trend in the development of interlayers. The overall development of the interlayer shows a trend of decreasing first and then increasing downstream along the sedimentary direction. A logging identification method is proposed for the unique gravelly interlayers in sandy conglomerate reservoirs, which can effectively improve the accuracy of interlayer identification and is of great significance for the efficient development of sandy conglomerate reservoirs.
