摘要
储层的物性通常包括其孔隙性、渗透性、孔隙结构以及非均质性等。其中孔隙性和渗透性是储集层的两大基本特征,也是衡量储集层性能好坏的基本参数。储层的孔隙性是指空隙形状、大小、连通性与发育程度。岩石的孔隙度越大,储集流体的能力越强。储层的渗透性是指一定压差下,岩石允许流体通过的能力。孔隙度的好坏直接决定了岩层储存油气的数量,渗透率的好坏则控制了储集层内所含油气的产能。
The reservoir physical characteristics usually include porosity,permeability,pore structure and heterogeneity,and so on.Of them,the porosity and permeability are the two basic reservoir characteristic,and also the basic parameters to evaluate the bad or good of the reservoir performance.The porosity of reservoir refers to the void shape and its size,connectivity and development degree.The greater the porosity of the rock,the stronger the ability of the reservoir to move.Reservoir permeability refers to the ability of a rock to allow fluid to pass through in a certain pressure differential.The porosity of the reservoir directly determines the volume of the oil and gas storage,and the good or bad of the permeability determines the oil and gas productivity in the reservoir.
