深层油气藏勘探前景分析

Analysis of Deep Oil and Gas Reservoirs Exploration Prospect

系统总结了国内外深层油气的最新研究进展和勘探成果,指出深层具备了形成油气藏的基本条件,并已发现了一系列的油气藏。在特定条件下,深层的砂砾岩、碳酸盐岩和火山岩等均能发育成为工业性油气储层。深部油气藏具有近源特征,垂向运聚成藏是其基本模式,由于构造运动的破坏,多期成藏较为常见。我国深部油气资源丰富,是含油气盆地油气勘探的重要接替领域。

This thesis systematically summarizes the latest research progress and petroleum exploration results in the deep oil and gas fields both at home and abroad. It points out that the deep layer has the basic conditions for forming the oil and gas reservoirs and a series of oil and gas reservoirs have been found in this field. Under the specific conditions, the deep-layer glutenite, carbonate rock and volcanic rock can develop into the commercial oil and gas reservoirs. The deep oil and gas reservoirs are characterized with the near- source property. The vertical migration and accumulation is the basic pattern for such reservoirs. The multi-stage oil and gas accumulation is quite common owing to destruction of structural activities. China is rich in the deep oil and gas resources. The deep field is an important substitute area for exploration of the oil and gas basins.
