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。因此,进一步认识火山岩气藏,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。本文对SC45区块火山岩气藏产能分布规律与产能控制因素进行了详细的分析,为后期的布井开发提供参考依据。
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. Therefore, further understanding of volcanic gas reservoirs provides sufficient technical basis for the future dynamic prediction of volcanic gas reservoirs, laying a good foundation for accelerating the gas reservoir production speed, correctly developing the development plan and scientific development of gas reservoirs. In this paper, the production distribution and control factors of volcanic gas reservoirs in SC45 block are analyzed in detail, which provides a reference for later wellbore development.
