摘要
针对低阻油层测井资料解释的含油饱和度往往偏低 ,造成油水层难以识别的问题 ,提出了用测井毛管资料综合法 ,该方法是以岩芯样品的实测孔隙度 (ψ)分析和压汞实验室毛管压力与油藏条件下毛管压力、毛管压力与含油高度 ( H)的关系转换 ,统计得出了相对含油体积与孔隙度、含油高度的关系 ,利用该关系可估算储层的含油饱和度 ,与工作站解释相结合 ,应用于大安北葡萄花油层 ,与试油对比 。
The lower resistivities of reservoirs always result in the lower oil saturation in log interpretation and difficulty in recognizing oil and water layers.A method of calculating oil saturation with log capillary pressure data is discussed here.Based on the analysis of porosity measured with core samples and the transmitting relationship between the capillary pressure in mercury injection laboratory and that in pool,and between the pressure and the oil bearing height,the author gives the expression of relative oil bearing volume with porosity and oil bearing height.With this expression,oil saturation of reservoirs can be estimated.Combined with imterpretation in workstation,the applying result in Putaohus Reservoirs of Da'anbei District is perfect.
