Abstract: Lithology of Bozhong 19-6 buried hill structural belt is very complicated.As a result,it is difficult to accurately calculate the porosity parameters directly from the log curve. The data of logging and experimental cores were used to analyze the lithology of buried hill reservoirs of Archean from the aspects of alteration, logging response characteristics,porosity,mineral content and fractures. A heavy mineral identification model was established and double indicator curves were used to identify heavy minerals. A set of mineral composition inversion models suitable for the complex lithologic reservoirs of buried hills of Archean in Bozhong19-6 was established. The results show that the metamorphic rocks,igneous rocks,and other rocks in the study area are complex in lithology,making it difficult to calculate accurate log curves for rock skeletons. The mass fraction of heavy minerals in buried hill formations is about 8%, and pyrite,siderite and iron dolomite are common. The effective porosity calculated by this inversion model agrees well with the core. The improved multi-mineral component inversion method can reduce the impact of complex mineral component on the physical properties of Bozhong 19-6 buried hill formation. The inversion mineral component and porosity are basically consistent with the experimental analysis. This study can provide some technical support for exploration and development in the area.

Key words: metamorphic rock, double indicator curves, heavy minerals, multi-mineral component inversion, Archean, Bozhong19-6 buried hill structural belt
