Examples
- Observation of drilling cores and casting - sections and the characters of pore structures and permeability of the matrix of the lower - ordovician carbonate in comparing with the lower limit of a reservoir for matrix reveal that the porosity , permeability , maximum pore diameter , saturation and median throat diameter in the matrix with undeveloped fissures , holes and solution pores are far lower than those of a reservoir limit although some micro - pores are developed in the matrix which therefore has no capacity of storing and producing oil - gas
摘要通过钻井岩心和铸体薄片观察，根据下奥陶统灰岩基质的孔渗特征和孔隙结构特征，并与基质作为储层的下限对照裂隙、洞穴和溶蚀孔洞不发育的灰岩基质，发现尽管有微孔隙的发育，但其孔隙度、渗透率、最大孔喉半径、饱和度、中值喉道半径等参数值远低于储层下限值，基本不具备储集和生产油气的意义。
