摘要
近年来,随着火山岩油气藏勘探开发的突破性进展,火山岩储层已经成为油气勘探的一个新领域。本文在调研了国内外火山岩储层研究成果的基础上,总结了火山岩储层储集空间类型及成因、储集空间的演化特征以及储层发育的控制因素。火山岩储层是内外因共同作用的结果,内因包括岩性岩相、喷发环境,外因包括构造作用和成岩作用。内因奠定了储层形成与分布的基础和储集空间的发育程度;外因对储层的储渗性能有明显改造。最后指出了火山岩油气储层成因研究中存在的一些问题,并且针对这些问题提出了今后的研究方向。
Volcanic reservoirs have become a new target of oil and gas exploration in recent years along with the breakthroughs in exploration and development of volcanic reservoirs. On the basis of investigation of the research results of volcanic reservoirs at home and abroad, this paper summarizes the types and geneses of reservoir space, the evolution of reservoir space and the controlling factors of reservoir formation. Volcanic reservoir is a result of common effects of internal and external causes. Internal causes include lithology, lithofacies and eruption environment; and external causes contain tectonism and diagenism. Internal causes determine the formation and distribution of reservoirs and the development of reservoir space; external causes reform reservoir properties. Some problems in the research of volcanic reservoir genesis are pointed out and the scope of future research is proposed in light of these problems.
