Abstract:

The traditional petroleum theory is helpful to search oil in sedimentary rocks. However, as oil-gas exploration has been intensively concentrated on sedimentary regions, the oil-bearing sedimentary regions become less and less. To look for oil in non-sedimentary areas caught more and more attention. This paper analyzes the oil-gas potential in the volcanic rocks worldwide, and studies the oil-gas reservoir formation conditions of volcanic rocks in basins. The volcanic-hosted oil-gas reservoir is normally located at the lower sequences, where with a low exploration but high potential shall be a new vital oil-gas exploration area. Some volcanic basins in circumPacific, Mediterranean sea and middle Asia are of good oil-gas reservoir-forming conditions, where can become the major areas for volcanic-hosted oil-gas.

Key words:

volcanic rocks; oil-gas resources; oil-gas reservoir

摘要：

传统石油地质理论在沉积岩层中寻找和开发了巨大的油气资源，然而，可寻找的空间越来越少，非沉积岩层中寻找油气越来越受到人们的重视。本文分析了目前全球在火山岩地层中已发现的油气资源潜力，认为含油气盆地中的火山岩具备形成大型油气藏的条件，往往分布在含油气盆地的中下部组合，勘探程度低，资源潜力大，是未来全球油气勘探的重要新领域。环太平洋、地中海和中亚地区各个含火山岩盆地具备良好的火山岩油气成藏条件，是今后火山岩油气发现的主要区域。
