Abstract

Previous studies indicate that nanotechnology can significantly enhance the effectiveness of enhanced oil recovery (EOR) techniques, particularly hot fluid injection. The efficiency of the injection process can be significantly influenced by the nanofluid's thermophysical properties (TPPs). However, laboratory examinations of TPPs on the performance of nanofluid-based EOR techniques are time-consuming and expensive, and theoretical models can also be inaccurate. To address this challenge, machine learning (ML) models can efficiently predict nanofluid TPPs and their impact on oil recovery performance. This study uses six ML algorithms: the K-Nearest Neighbors (KNN), the Theil-Sen regressor, the decision tree (DT), the lightGBM, the Bayesian ridge, and the LASSO. Using the VR-fluid thermal conductivity and temperature created the formula and the model for thermal conductivity of the VR-VGO nanofluid with 2 mass% CuAeg, and also by the VR-VGO nanofluid with 2 mass% CuAeg thermal conductivity and temperature created the formula and model for VR-fluid thermal conductivity. The maximum R-squared (R2) for the VR-VGO nanofluid with 2 mass% CuAeg for the formula and the model attained by the Theil-Sen regressor and the KNN, which respectively are 0.997 and 0.999 in linear formation, and the best R2 for the VR-fluid for the formula and the model reached by the BR and the KNN respectively are 0.98 using the polynomial formation, and 0.995 using the linear form. The VR-fluid viscosity and temperature calculate the VR-VGO nanofluid with 2 mass% CuAeg viscosity and the VR-fluid viscosity are calculated using the VR-VGO nanofluid with 2 mass% CuAeg viscosity and temperature. The best R2 for the VR-VGO nanofluid with 2 mass% CuAeg reached by the Theil-Sen regressor for the formula, the KNN for the model, and the R2 score for the VR-VGO nanofluid with 2 mass% CuAeg viscosity respectively are 0.999 and 0.999 in linear form. The best R2 value for the VR-fluid for the formula by the BR is 0.999, and for the model by the KNN is 0.999 in linear form.

开发用于预测可用于提高采收率的VR/VGO纳米流体热物性的机器学习模型
先前的研究表明,纳米技术可以显著提高提高采收率(EOR)技术的有效性,特别是热流体注入技术。纳米流体的热物理性质(TPPs)会显著影响注入过程的效率。然而,在实验室测试TPPs对基于纳米流体的EOR技术的性能既耗时又昂贵,而且理论模型也可能不准确。为了应对这一挑战,机器学习(ML)模型可以有效地预测纳米流体TPPs及其对采收率的影响。本研究使用了六种机器学习算法:k近邻(KNN)、Theil-Sen回归器、决策树(DT)、lightGBM、贝叶斯脊和LASSO。利用虚拟现实流体的导热系数和温度建立了含有2质量% CuAeg的虚拟现实- vgo纳米流体的导热系数公式和模型,并通过含有2质量% CuAeg的虚拟现实- vgo纳米流体的导热系数和温度建立了虚拟现实流体的导热系数公式和模型。对于2质量% CuAeg的VR-VGO纳米流体,采用Theil-Sen回归量和KNN得到的公式和模型的最大R-squared (R2)在线性形式下分别为0.997和0.999,采用多项式形式的BR和KNN得到的公式和模型的最佳R2为0.98,采用线性形式的R2为0.995。虚拟现实流体的粘度和温度是用2质量% CuAeg粘度的虚拟现实- vgo纳米流体计算的,虚拟现实流体的粘度是用2质量% CuAeg粘度和温度的虚拟现实- vgo纳米流体计算的。公式的Theil-Sen回归量、模型的KNN和黏度为2质量% CuAeg的VR-VGO纳米流体的线性R2分别为0.999和0.999。基于BR的公式和基于KNN的线性模型的最佳R2值分别为0.999和0.999。
