【摘要】 含油饱和度是计算油田储量、编制油田开发方案、评价水淹层的基本参数之一。在目前我国大部分油田,尤其东部老油田相继进入高含水后期开采阶段以后,含油饱和度解释工作显得更为重要。在多种电性参数对比的基础上,优选深侧向电阻率作为含油饱和度解释的基本参数,并建立了解释模型。电阻率经厚度因素校正后,含油饱和度解释取得了比较理想的效果,尤其是薄油层的解释精度有了很大提高。解释结果对比表明,文章所提出的厚度参数校正方法是可行的。更多还原

【Abstract】 Oil saturation is one of the main reservoir parameters in calculating petroleum reserve, planning oilfield development program and evaluating flooded zones. At present, most of oilfields, especially eastern oilfields in china, step into the period of high water bearing, so it gets the more important work to accurately interpreting oil saturation. Base on contrasting several electric parameters, this paper screens the deep lateral logging resistivity to interpreting oil saturation, and builds its model. Interpretation accuracy of oil saturation in oil bearing formation, especially in thin reservoir, is greatly improved as resistivity is corrected by formation thickness. The interpretation result shows that the parameter correction method of resistivity and the interpretation model of oil saturation fit into reservoir development.更多还原
