The dispersion coefficient is a key physical parameter for enhanced gas recovery (EGR) and
reflects the degree of mixing between the displacing-fluid CO 2 and natural gas. However …

Calcite cement is the dominant control on reservoir quality in turbidite sandstones of the
Upper Permian Bell Canyon Formation, Delaware Basin. These well-sorted, very fine …

碎屑岩地层普遍具有非均质性. 然而, 在勘探尺度的油气运聚和成藏研究中, 输导层内部成分,
结构和物性等方面的非均质性被忽略, 致使输导层的非均质性特征及其对地层流体和油气运聚的 …

针对陆相碎屑岩特超低渗储层油气运聚成藏研究中存在的问题, 选择鄂尔多斯盆地西部延长组下
组合砂岩油藏储层为研究对象, 分析其沉积结构构造, 成岩作用与致密化过程的非均质性 …

储层孔渗物性的非均质性客观存在, 对于地下流体的流动过程影响明显, 这不仅对于油气田开发
十分重要, 在油气运聚成藏研究中也不能忽视. 文章讨论一类较为特殊的结构非均质性 …

Authigenic clays and calcite cements are important in the development of reservoir tightness
and the formation of hydrocarbon sweet spots. We investigated Jurassic low-permeability …

Heterogeneity is an essential feature of tight sandstones because it is directly related to
reservoir quality. The Upper Triassic Xujiahe Formation in the Sichuan Basin was used as a …

Sandstones with carbonate cements are found in a variety of depositional settings (eg
fluvial, lacustrine, deltaic, shallow marine) with abundances ranging from just a few volume …

Understanding the diagenetic evolution of carbonate cementation in hydrocarbon reservoirs
is critical to better reconstruct the history of fluid flow during petroleum accumulation. The …

Reliable modeling of meandering fluvial reservoirs is challenging because of the
heterogeneity in magnitude and pattern of porosity and permeability related to depositional …
