摘　　要：通过岩石薄片观察,运用综合地质研究的方法,定量分析了刘庄油田储层孔隙度、渗透率、碳酸盐含量,并进一步分析了影响刘庄油田孔隙发育的主要因素。孔隙发育程度及其物理特征直接影响油气藏的形成和油气藏的质量。沉积环境和沉积特征是孔隙发育的先决条件,成岩作用直接影响储层物性的好坏。在成岩过程中,交代作用和溶解作用可使孔隙度进一步增大,压实以及压溶作用则使储层孔隙性能变差。通过研究搞清了刘庄油田储层孔隙发育的规律,对该油田的开发部署具有借鉴意义。Reservoir porosity,permeability and carbonate content are quantitatively analyzed through thin section observation and comprehensive geologic study.The influence factors of pore development in Liuzhuang oilfield are also analyzed.Pore development degree and physical property directly affected oil and gas accumulation and reservoir quality.Depositional environment and characteristics were preconditions of pore development,and diagenesis decided petrophysical property.During diagenetic process,metasomasis and dissolution further contributed to porosity.Compaction and pressolution caused porosity variation.Reservoir pore development in Liuzhuang oilfield is understood,this may guide development deployment in this oilfield.
