Both compositional and textural maturities of the sandstone are low, whereas such reservoir features as porosity and permeability are generally high. 巖石的成分成熟度和結構成熟度普遍低，而儲層物性通常卻很好。
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. 沉積微相和成巖作用是控制本區灘壩砂體儲層物性的主要因素。
