摘要(Abstract)：
为提供高精度储层参数,通过室内模拟地层条件下岩电实验研究,得到了葡西、新肇和卫星地区岩电参数;利用实验得到的岩电参数计算地层的含水饱和度,与理论值和试油结论进行了对比分析,结果表明,不同地区、不同层位岩电参数变化范围较大;对同一油层而言,利用理论值与实验值进行饱和度计算,实验参数更为合理些;同时在方法上探索了影响岩电实验效果的一些因素及应注意的问题。
The rock electricity experiments under the simulated condition were used to improve the interpretation accuracy of the formation parameters. In this paper the four key constants of Archie' s formula of Puxi area, Xinzhao area and Weixing area of Daqing Oilfield were obtained by the experiments. Contrasting the ?' calculated saturation from the experimental constants with theoretic and field-testing results, the constants varied widely from region to , region, and layer to layer. The experimental constants are much favorable than the theoretic ones for the interpretation of water saturation. So the measured data can improve interpretation accuracy of formation oil saturation by Archie' s formula. Many factors that influent the measurement results are also discussded, and the reasons which cause errors during the rock electricity experiments are analyzed completely.
