湖北宜昌早奥陶世生物礁储层孔隙发育，类型多样，主要有骨架孔、生物体腔孔、溶蚀孔和微孔隙等８种类型。物性分析表明，礁体储层物性较差，以低孔低渗为特点，导致这种储集物性的原因一方面与礁体沉积特征有关，另一方面与胶结作用、压实作用等破坏性成岩作用的改造有关。探讨了礁体储层成因与构造埋藏史、有机质演化史和孔隙演化史的关系及成藏机理。
The pores of the Early Ordovician reef reservoirs in Yichang, Hubei Province are well developed in various types. There are mainly 8 types of skeleton pores, biological cavity pores, dissolved pores and micro-pores. Physical property analysis shows that the reef reservoirs are poor in physical properties and characterized by low porosity and low permeability. The reasons for this reservoir property are related to sedimentary characteristics of reefs on the one hand, and destructiveness such as cementation and compaction Diagenesis related to the transformation. The relationship between reservoir genesis and tectonic burial history, organic matter evolution history and pore evolution history and reservoir forming mechanism were discussed.
