摘要： 北三台地区石炭系火成岩储集层具有强非均质性,通过研究认为,储集层物性的非均质性主要受风化界面、岩性、岩相和裂缝等因素影响,纵向上受距不整合面距离影响,相同距离则受岩性和溶蚀作用影响,裂缝则加剧了储集层的溶蚀,提高了其连通性和扩大了溶蚀规模,据此,探讨了该类火成岩有利储集层形成的两种模式。

Abstract: The characteristics of reservoir lithology and petrophysical property as well as serious heterogeneity of the target zones in studied area are introduced in this paper. The study suggests that the heterogeneity is mainly influenced by weathering interface, lithology, lithofacies and fractures. In vertical, the effect of unconformity depth on heterogeneity is a key factor, and for the same depth, it is influenced by the lithology and dissolution, while the fractures expand the connectivity and scale of reservoir dissolution. Accordingly, two models for forming the favorable volcanic reservoirs are discussed.

Key words: Beisantai area, Carboniferous, volcanic reservoir, heterogeneity, influencing factor
