摘要

The Mesozoic buried hill of KL16-1 structural belt in Laizhou Bay Sag is an important oil and gas exploration area in Laizhou Bay sag, which has a good exploration prospect. Influenced by tectonic evolution, the types and main controlling factors of Mesozoic volcanic reservoirs are not clear, which affect the exploration and development of buried hill reservoirs. In this study, the lithologic characteristics, reservoir space types and the main controlling factors of volcanic reservoir development were systematically studied by casting thin sections, core data, well logging data and analytical laboratory data. The reservoirs in the study area are mainly volcanic clastic reservoirs, and the reservoir space types are mainly primary and secondary, and the primary reservoir space is mainly secondary. Comprehensive analysis shows that the main controlling factors of reservoir development are volcanic rock lithology, tectonic movement and diagenesis. The research results of this paper have certain significance for the fine study of the Mesozoic volcanic buried hill reservoir and the prediction of oil and gas reservoirs in the KL16-1 structural belt of Laizhou Bay Sag.
