| 摘 要： | 束缚水饱和度的大小是划分油气层与水层的重要依据之一.在岩石物理实验的基础上,分析影响束缚水饱和度大小的各种因素,利用彼此之间的关系求取束缚水饱和度的大小.以XX盆地低渗储层为例,分析低渗储层束缚水饱和度的特点,建立了束缚水饱和度与孔隙度、渗透率、气柱高度等的模型,应用到实际资料中,检验各种模型的适用性与准确性,取得了较好的效果.

| Abstract: | The irreducible water saturation is an important indicator of dividing oil ＆ gas layer from water layer. The main factors in- fluencing the amount of irreducible water saturation have been analyzed on the basis of petrophysical laboratory testing results. Then the amount of irreducible water saturation can be calculated with the relationships between the affecting factors and the irreducible water saturation. After analyzing the characteristics of the irreducible water saturation of low permeable layer, the models of irreduc- ible water saturation with porosity, permeability, and the height of gas reservoirs have been established with an illustration of the low permeable layers in XX Basin. The applicability and accuracy of the models are checked by being applied in the actual situation and the result is good. |
