摘要: 针对天然气藏描述过程中气层难以识别和用常规阿尔奇公式计算的含气饱和度(Sg)偏低的问题, 利用阿尔奇公式提出了改进方法, 从而用交会图技术有效地识别出气层, 提高了含气饱和度解释精度, 使其与实际含气饱和度相符, 具有较强的理论基础和使用价值。

Abstract: In the light of difficulty in identificating gas layer during natural gas description and lower gas saturation value with conventional Archie formula, this paper presented a modified method with Archie formula, in which application of cross plot technique can effectively identify gas layer, its results accord with actual gas saturation.This method has solid theoretical basis and practical value.
