套管地层电阻率等套管电阻率测量仪器广泛应用于油井生产阶段的油藏动态监测，以评价剩余油的分布。然而，基于单注入电极的通用TCR模型仍然存在两个缺点：钢-套管电阻的真实值难以获得，电极尺度机械公差的影响难以预测。本文提出了一种基于双注入电极的创新模型。在该模型中，所有需要的变量都可以同时测量；在此基础上，采用补偿算法获得了实际的套管阻力。通过自适应目标导向的hp有限元仿真，证明了该方法可以有效地减小电极尺度对机械公差的影响。因此，TCR的测量精度大大提高。
Through-casing resistivity (TCR) measurement instruments such as Cased Hole Formation Resistivity are extensively used for the dynamic monitoring of oil reservoirs during the production phase in oil wells to evaluate the residual oil distribution. However, two shortcomings still exist in the common TCR model based on single-injection electrodes: The real value of steel-casing resistance is difficult to acquire, and the effect from mechanical tolerances of electrode scale is unpredictable. This paper proposes an innovative model based on double-injection electrodes. In this new model, all the required variables can be measured simultaneously; furthermore, a compensating arithmetic method is employed to obtain the real casing resistance. Self-adaptive goal-oriented hp-finite-element simulations have been performed to prove that the influence of mechanical tolerances of electrode scale can be reduced effectively. Therefore, the TCR measurement accuracy is highly improved.
