卧龙河气田石炭系储层特征

Characteristics of Carboniferous Reservoir in Wolonghe Gas Field

储集空间类型和孔喉结构是影响储层质量的重要原因,通过常规、铸体薄片和压汞分析以及物性测试手段对储层孔隙、喉道的类型,以及储层物性特征进行研究分析,这对深入认识本区的储层特征及其控制因素有积极作用。研究表明,卧龙河气田石炭系储层主要以孔隙-裂缝型储层,孔隙岩石结构复杂,以低孔隙为主,渗透率和含水饱和度变化较大。

Reservoir type and pore throat structure are the important factors that affect the quality of reservoir. The characteristics of reservoir pore,throat type and reservoir physical properties were studied by conventional,cast sheet and mercury intrusion analysis and physical property test,which had a positive effect on the reservoir characteristics and its controlling factors. The study shows that the Carboniferous reservoirs in the Wolonghe gas field are mainly composed of pore-fractured reservoirs,and the pore rocks are complex,with low porosity and permeability and water saturation.
