| 摘 要： | 西湖凹陷目前已发现的油气层主要集中在平湖组和花港组储层之中。平湖组主力烃源岩的有机质类型以Ⅲ型为主,主要形成气藏（含凝析气藏）和轻质油藏,其具有流动性强、极易挥发等特点,烃类损失较大。通过目前应用的几种录井技术来看,泥浆综合气测录井能较好的识别油气层,通过对C1参数的矫正能够很好的识别出油气显示层,根据各气测参数的特征变化,并能对油气层的性质进行初步的较准确评价。地化录井、定量荧光录井由于受到烃类损失大的影响,在对油气层识别及评价中不及气测录井敏感。

| Abstract: | Major oil and gas reservoirs in Xihu Sag developed in Pinghu and Huagang formation.Organic matter of Pinghu source rocks is of type III,and main hydrocarbon type in Xihu Sag is gas reservoir（condensate gas reservoir） and light oil reservoir,which is characterized by high fluidity and high volatility.At present,several logging methods have been used in Xihu Sag,in which gas logging can evaluate the hydrocarbon type initially while drilling.Meanwhile,geochemical logging and quantity fluorescence test are not so effective as gas logging in hydrocarbon evaluation. |
