【摘要】 利用多元线性回归分析法,以某油田灰岩岩芯的酸岩反应动力学实验数据为基础,建立并求取了酸岩反应速率与其影响因素间的多元线性回归模型,并对方程进行了验证评价,通过求取各因素的标准化回归系数来评价影响酸岩反应速率的4个主要影响因素:酸液浓度、地层温度、酸液粘度和圆盘转速,结果表明,它们对酸岩反应速率影响程度的大小顺序依次为:粘度>转速>温度>浓度,为灰岩的酸压施工提供了参考依据。更多还原

【Abstract】 Using multiple linear regression analysis method,four main inflencing factors of acid-rock reaction rate: the acid concentration, formation temperature, acid viscosity and disc speed of rotation are analyzed and evaluated on the basis of experimental data of acid-rock reaction kinetics of of an oilfield limestone cores.The results show that the degree of the size of the order affecting the acid-rock reaction rate is viscosity > speed > temperature > concentration,which provides a reference for limestone acid fracturing treatment.更多还原
