中文摘要：

双频激电井地电位法相对其它常规井地电位方法有独特优势和特点，利用该方法研究剩余油分布具备良好的理论和应用前景．但其理论机理、仪器方法及数据解释尚处于起步阶段．本文以大庆油田6-P2325井为例，首次进行了双频激电井地电位探测，得到了地表的电位差分布图，把该图与前期结果进行对比表明应用该方法研究剩余油分布是可行的，可为剩余油分布研究提供信息数据，也可为深入研究大功率双频激电测井理论机理和仪器研制提供现场试验数据和依据．

英文摘要：

The dual frequency induced polarization and borehole-to-surface potential （DFIP-BSP） method has unique advantages and characteristics over other conventional borehole-to-surface potential method. It has academic and applied prospect with this method to research the distribution of the residual oil. But it is still at the starting stage of the research of theoretical mechanism,instrument method and data interpretation. This paper takes the 6-P23225 well as an example to present, the exploration of the DFIP-BSP method firstly performed and the distribution of potential detected. Comparing the results with previous work shows this method is feasible and provides the field test data and basis for researching theoretical mechanism and high-power DFIP ＆BSP instruments.
