摘要

The lithology section structure of Hailar Basin is very complex not only for the existence of volcanic lava and the normal sedimentary rocks, but also for the presence of volcanic transitional lithology. Conventional logging curves can well reflect the lithology with significant characteristics and larger sediment thickness. But transitional lithology with thin deposition thickness and complex composition need to be determined through the relationship between upper and lower lithologic changes. Thus, based on the correlation of main lithology and log response, this paper proposes and establishes 4 kinds of logging response patterns of continuous lithological sections, and presents examples of corresponding wells. Application of logging response pattern of continuous lithological section improves the identification accuracy of deposition thickness and complex composition of transitional lithology.
