张庆国．ＳＴＭ低阻凝析油气藏测井解释研究．测井技术，１９９８，２２（３）：１８６～１８９ＳＴＭ三叠系凝析油气藏为罕见的低阻凝析油气藏。储层岩性复杂，油气层电阻率极低，泥质影响特殊，对测井解释造成极大困难。本文从实际地质资料分析入手，讨论了复杂岩性泥质砂岩测井解释方法、低阻油气层饱和度的确定方法。新方法能有效地识别低阻油气层。

The Triassic condensate gas reservoir in STM Oilfield is a kind of rarely low resistivity reservoir. Because of its complex lithology, the very low resistivity of hydrocarbon zone and the special effect of shale, it was very difficult to make log interpretation. Through the analysis of real geology information, the log interpretation method for the complex shaly sand and the saturation calculation method for the low resistivity reservoir have been discussed.Oil & gas zone by the new method can be easily identified, ensuring the smooth reservoir description.
