An advanced geoelectric method for monitring EOR precess has been developed by the Geophysical Laboratory in Kyushu University, Japan. The 4D method named as Fluid Flow Tomography has been applied to monitor fluid-flow behaviors before steam injection, during injection and after steam injection for three months by the joint research works of Kyushu University, JAPEX and CANOS on the Hangingstone test site in Fort McMurray, Athabasca area, Alberta, Canada.With the automatic recording system controlled by a personal computer, charged potentials and spontaneous potentials can be simultameously measured with two seconds interval as a function of time at multiple stations up to 120 channels surrounding operating boreholes. Fluid-flow behaviors in the oil sand foramtion were visualized as a function of time by making contour maps of residual potentials derived from spontaneous polarization data and relative changes of apparent resistivity distributions during the 8th thermally enhanced oil recovery process on the Hangingstone test site.Three dimensional distributions of injected steam, condensed water, oil bank and bitumens could be imaged as a function of time by the 3D inversion of Spontaneous Polarization data and Charged Potential data separated by data processings of digital filtering techniques from the observed data obtained by the present Fluid Flow Tomography method.

日本九州大学地球物理实验室开发了一种用于监测EOR过程的先进地电方法。九州大学、JAPEX和CANOS联合研究在加拿大阿尔伯塔省阿萨巴斯卡地区Fort McMurray的Hangingstone试验场进行了为期三个月的注汽前、注汽中、注汽后流体流动行为监测，称为流体流动层析成像（Fluid Flow Tomography）。使用由个人计算机控制的自动记录系统，可以在作业井眼周围多达120个通道的多个站点同时测量带电电位和自发电位，间隔两秒钟，作为时间的函数。通过对杭ingstone试验场第8次热采过程中自发极化数据和视电阻率分布的相对变化曲线绘制剩余电位等值线图，将油砂地层流体流动行为可视化为时间函数。通过对自发极化数据和带电电位数据进行三维反演，利用数字滤波技术进行数据处理，从现有流体层析成像方法获得的观测数据中分离出注入蒸汽、凝结水、油库和沥青的三维时间分布。
