Toolebuc地层是澳大利亚东北部埃罗曼加(Eromanga)盆地广泛分布的白垩系岩石单元。这一地层主要由页岩和粉砂岩组成,在某些部位碳质和沥青质矿物富集,人们认为这是石油的一个重要的潜在来源—油页岩。一、油页岩人们用“油页岩”这个名词来描述若干种有机质或沥青质岩石。包括Toolebuc地层在内的大多数油页岩是在耗氧的浅海、湖泊、沼泽沉积的。油页岩形成的关键因素是有能够使有机物保存下来的早期贫氧条件。目前,世界上许多油页岩中已获得了每吨油页岩达4000升的石油产量。虽然Toolebuc地层油页岩中平均产油量只有每吨60升,但油页岩的储量之大,对
The Toolebuc Formation is a widely distributed Cretaceous rock unit in the Eromanga Basin, northeastern Australia. This formation is mainly composed of shale and siltstone. Carbonaceous and asphaltene-rich minerals are enriched in some areas and are considered to be an important potential source of oil - oil shale. First, the oil shale People use the term “oil shale” to describe a number of organic matter or asphaltene rocks. Most of the oil shale, including the Toolebuc Formation, is deposited in oxygen-laden shallow seas, lakes and swamps. The key factor in the formation of oil shale is the early depletion of oxygen that can hold down organic matter. At present, many oil shale in the world has obtained 4,000 liters of oil per tonne of oil shale. Although the average oil yield in Toolebuc stratigraphic oil shale is only 60 liters per ton, the reserves of oil shale are large,
