利用油气化探技术评价青藏高原羌塘盆地海相碳酸盐岩地区构造的含油气性

The assessment of petroleum resource potential of marine carbonate region using surface geochemical exploration technique in Qiangtang basin, Tibet, China

摘要: 用浅表地球化学方法评价青藏高原碳酸盐岩区块的油气资源潜力是盆地勘查阶段的战略问题之一。研究了羌塘盆地托纳木区块的油气地球化学异常特征、异常成因和圈闭的油气属性。研究表明，托纳木背斜是羌塘盆地非常有远景的油气靶区，油气化探能够为区块油气资源评价提供重要的地球化学信息。

Abstract: Geochemical assessment of petroleum resource potential in a basin is one of the strategic problems. This paper focuses on the surface geochemical anomalies , diagnostic hydrocarbon and petroleum characteristic of Tuonamu anticlines. Our results show that Tuonamu anticline is one of the perspective petroleum targets, and surface geochemical exploration can provide important oil and gas information in local assessment of petroleum resource.
