| 摘 要： | 通过南方地区页岩气藏的储层特征和赋存方式的研究，认为页岩各组分含量的准确计算直接关系到含气量评价的精度.以南方3个工区计74块岩心样品组分分析实验为基础，提出页岩的五元工业组分体积模型和体积含量计算方法.对其中表征页岩含气性最关键组分——干酪根（有机碳）含量，分别建立与三孔隙度、电阻率、铀元素等5条测井曲线的线性关系.通过有机碳敏感性分析，引入两种多元回归计算有机碳含量方法，确定了适用于3个南方地区有机碳含量的公式.3口探井应用实例表明该方法符合页岩气藏的实际，提高了页岩气层各组分含量的计算精度，取得了预期的地质效果.

| Abstract: | Based on the analysis of mineralogical composition of 74 rock samples from the shale gas reservoirs in three work areas in South China, the paper puts forward the volumetric model and calculating method of volume content for five commercial components, meanwhile, builds and analyzes the linear relations for kerogen content which is the key composition to characterize the gas content of shale. With two methods of multiple regression calculation, the formulae of organic carbon content in South China are ascertained, which have been proved to conform to actual situation of the shale gas reservoirs. |
