摘　　要：用地球化学方法进行测井解释不受储层岩石组成及储层流体物理性质的影响。Baskin和 Huang等 [2 ]的研究结果表明 ,根据不同的碳数分布范围可以直接划分出油层、气层和水层。例举了塔里木盆地及柴达木盆地运用这一方法对一些油层、气层和水层岩石抽提物的饱和烃色谱分析实验结果。此方法可用于随钻过程中识别油、气、水层 。Log interpretation with geochemistry technique is not affected by reservoir rock composition and formation fluid properties.Researches by Baskin and Huang show oil,gas and water intervals may be directly zoned in accordance with different carbon distributions.Applications to predict gas,oil and water intervals using reservoir extracts′ saturated hydrocarbon chromatography in Tarim and Caidam Basin are presented in this paper.The above geochemistry technique can be used to identify oil,gas and water intervals during drilling,and also to reevaluate oil and gas intervals of the old wells and the wells with poorer log responses.
