| 摘 要： | 针对长庆靖边下古生界气藏的储层非均性问题，采用地层系数非均质概率统计分析方法，结合试井分析认识，对储层非均质性进行定量描述和深入评价，并对储层非均质与压力传播速度的关系进行了研究。结果表明，地层系数变异系数、级差以及均方差均表明储层渗透率非均质非常严重；储层渗透率越高，压力传播越快，压力响应越大，随着孔隙度增加，压力传播速度减少。这类问题的解决具有实际意义，能够直接指导气田开发层位的选定和并网调整。

| Abstract: | The Lower Paleozoic reservoir of Changqing Jingbian Gas Field has serious heterogeneity.In order to research the reservoir heterogeneity,the great amount of calculation and analysis about the variation coefficient,difference of series and mean square deviation of these formations has been conducted based on core analysis data to make clear that the heterogeneity in and between layers is very great.The results show that the formation permeability is quite high,the pressure spread is quicker;and the pressure ... |
