Growing macroscale fold structures are one of the most dynamic and complex systems in
geology, where during fold growth pore fluid pressure, fluid temperature, and fluid …

Using examples from core studies, this article shows that separate identification of
mechanical stratigraphy and fracture stratigraphy leads to a clearer understanding of …

Natural fractures are effective reservoir spaces and the main seepage channel for tight
sandstones, which control the migration, enrichment, and productivity of oil and natural gas …

致密砂岩储层基质物性极差, 天然裂缝的发育为油气的运移与聚集提供渗流通道和储集空间,
有效裂缝的分布明显改善了致密储层储渗性能和单井产量. 利用岩心, 薄片, 测井资料及相关实验 …

A fracture network arrangement is quantified across an isolated carbonate platform from
outcrop and aerial imagery to address its impact on fluid flow. The network is described in …

Natural fractures provide the main path for fluid flow in tight oil reservoirs and can control the
flow direction in the subsurface. Tight sandstones commonly have intense mechanical …

深层致密泥岩盖层由于成岩程度高, 脆性强, 易发生脆性破裂并造成盖层泄漏, 因此,
盖层的完整性评价十分关键. 泥岩盖层的变形特征主要受泥岩密度和围压控制, 随着埋深增大 …

The existence of bedding planes in rock materials has an obvious impact on the material
mechanical properties and the failure process of engineering projects. In this study, a series …

Nearly 3,600 vertical joints were measured in sand-mud interbedded rock masses from 30
outcrops in the Yan'an area, China. Information such as joint spacing, joint aperture and the …

Through-going joints cutting across beds are often invoked to match large-scale
permeability patterns in tight carbonate reservoirs. However, despite the importance of these …
