Both compositional and textural maturities of the sandstone are low, whereas such reservoir features as porosity and permeability are generally high. 岩石的成分成熟度和结构成熟度普遍低，而储层物性通常却很好。
The sedimentary microfacies and diagenesis are considered as the main controlling factors of physical properties of the beach-bar sandstone reservoirs in the study area. 沉积微相和成岩作用是控制本区滩坝砂体储层物性的主要因素。
