Abstract

Abstract: The lithologic profile of pyroclastic rock is based on the sedimentary environment of multiple sources, which has the characteristics of lithologic grain variation of continental clastic rock and the characteristics of rock composition from different sources. Based on the physical characteristics of the logging project, the curve value contains two aspects of rock particle size and composition information, so it is necessary to judge the transition lithology with thin thickness and complex composition according to the change relationship between upper and lower lithology. According to the variation characteristics of pyroclastic rock in the logging response of Hailaer Basin, a continuous lithologic profile variation model is established, which effectively improves the identification accuracy of transitional lithology in the lithologic profile.
