摘要(Abstract)：

川东北地区嘉陵江组储层的岩性、物性及孔隙结构复杂,使得流体性质的判别成为测井解释工作中的一大难题。以碳酸盐岩储层测井解释原理为指导,通过分析电阻率值的分布范围、孔隙度—含水饱和度交会图上点子的分布特征以及P1/2累计频率曲线图上曲线的倾斜程度,对储层流体性质作了定性判别。结合钻井显示情况以及试油结果,认为电阻率绝对值法、孔隙度与含水饱和度交会法以及P1/2正态分布法在本区储层流体性质的定性判别中应用效果较好。
The complexity of lithology,physical property and the pore configuration in the carbonate reservoir of Jialingjiang Formation in NE Sichuan make the study of the fluid property discrimination a hard nut to crack.Under the guidance of the well logging interpretation rule of carbonate reservoirs,analyzing the distribution range of resistivity,the pattern of dot in φ-Sw crossplot and the slope degree of the curve in P1/2 ogive,the authors studied the qualitative discrimination of fluid property.According to the well drilling displays situation and the well testing report,such the methods that absolute value of resistivity,P1/2 ogive and φ-Sw crossplot are thought the best methods to discriminate the fluid property.
