火山岩气藏通常具有渗透性差异大、非均质性严重、气水分布复杂、孔隙结构复杂、岩石类型繁多、岩性复杂等特点,具有全然不同于常规气藏开发的特殊性和困难性。当今国内外已经发现的火山岩气藏数量有限,还没有形成可以借鉴的方法和经验。因此,进一步认识火山岩气藏,开展气井产能研究非常必要,也为今后火山岩气藏的动态预测提供充足的技术依据,为加快气藏投产速度,正确编制开发方案,科学开发气藏奠定良好的基础。通过研究,对SC45区块火山岩气藏的产能分布有了具体的认识,为气藏开发投产提供了理论依据和数据支撑。
Volcanic gas reservoirs are usually characterized by large differences in permeability, serious heterogeneity, complex gas and water distributions, complex pore structures, numerous rock types and complex lithologies, which are totally different from the particularities and difficulties of conventional gas reservoir development. At present, there are a limited number of volcanic gas reservoirs that have been discovered both at home and abroad, and methods and experiences that can be used for reference have not been formed yet. Therefore, it is necessary to further understand volcanic gas reservoirs and conduct gas well productivity research, and also provide sufficient technical basis for the future dynamic prediction of volcanic gas reservoirs, which lays a good foundation for accelerating gas reservoir production speed, correctly formulating development plans and developing gas reservoirs scientifically . Through the research, the production distribution of volcanic gas reservoirs in SC45 block has been specifically recognized, which provides theoretical basis and data support for the development and production of gas reservoirs.
