一些大规模油气体地最近在中国在海洋的碳酸盐被发现了,特别在揭示有利探索的深水库的重要发现勘探。Tazhong 区域是在 Tarim 盆的一阶的构造单位,在有的地方将近万亿在在 Lianglitage 的奥陶纪石灰石礁石公寓建筑群的天然气资源的立方的米形成。水库是架边礁石公寓建筑群,由极端低的孔描绘了,低渗透并且强壮异构,与 4500 6500 m 的当前的埋葬深度。研究发现 Lianglitage 形成的深水库的形成和分发被早高精力的沉积外形控制,自从喜玛拉雅的时代,腐蚀,而是破裂网络由强壮的煤气控告的进程形成了不仅,它在优化并且改善水库性质起了一个重要作用。这篇论文讨论在之间的关系强壮以后煤气控告并且在深奥陶纪碳酸盐水库的水库能力的改进,并且另外 builts 相应机制和模式,它为有益的探索目标的预言和评估是有利的。
Some large-scale oil-gas fields have recently been discovered in marine carbonate in China, especially the significant discoveries in deep reservoir that reveals a favorable exploration prospect. Tazhong area is the first-order tectonic unit in Tarim Basin, where there are nearly trillion cubic meters of natural gas resources in the Ordovician limestone reef flat complex in Lianglitage Formation. The reservoir is shelf edge reef flat complex, characterized by ultra-low porosity, low permeability and strong heterogeneous, with a current burial depth of 4500―6500 m. Studies find that the formation and distribution of deep reservoir of the Lianglitage Formation were controlled not only by the early high-energy sedimentary facies and corrosion, but the fracture network formed by the strong gas-charging process since the Himalayan epoch, which played an important role in optimizing and improving reservoir properties. This paper discusses the relationship between the strong later gas-charging and the improvement of the reservoir capacity in deep Ordovician carbonate reservoir, and also builts the corresponding mechanisms and modes, which is favorable for the prediction and evaluation of the advantageous exploration targets.
