摘要
二元复合驱数值模拟中涉及一些描述驱油机理的物理化学参数,其准确性直接影响复合驱方案的预测结果。而这些参数主要通过室内实验测得,再由油藏人员根据经验进行修正,会因为实验条件差异导致参数误差,进而使方案预测结果与实际效果有偏差。为提升二元复合驱数值模拟的准确性,本文基于物模实验及数值模拟技术,建立了实验尺度数值模型;在物化参数敏感性分析的基础上,通过拟合驱油实验数据来修正物理化学参数,实现了二元复合驱数字化驱油实验平台的建立;并在矿场数值模拟中进行了验证。既解决了物化参数转化的问题,又提升了矿场复合驱数值模拟的准确性。与传统物理模型相比,该数字化实验平台增强了可视化、可再现性和可重复性,降低了实验成本和时间。
Some physico-chemical parameters describing oil displacement mechanisms are involved in the numerical simulation of binary composite flooding.Their accuracy directly affects the predictive results of composite flooding schemes.Currently,these parameters are mainly measured through laboratory experiments and subsequently corrected by reservoir engineers based on experience.Differences in experimental conditions can lead to parameter errors,causing deviations between predicted results and actual performance.To improve the accuracy of numerical simulation for binary composite flooding,this study established an experimentalscale numerical model based on physical-model experiments and numerical simulation techniques.Based on sensitivity analysis of physico-chemical parameters,a digital experimental platform for binary composite flooding was developed by calibrating physicochemical parameters through fitting experimental data.This platform was validated through field-scale numerical simulation.This approach not only resolves the challenge of parameter conversion but also enhances the accuracy of numerical simulation for composite flooding in mining sites.Moreover,compared with traditional physical models,this digital platform improves visualization,reproducibility,and repeatability,while reducing experimental costs and time.
