【摘要】 依据油田生产中常见的油、水两相电阻率异常差异,提出了一种油水两相流动阵列电阻成像方法。该方法通过测量相邻电极电流激励模式下的电压变化,运用基于微扰原理的线性反投影图像重组算法,再现井筒测量截面上的油、水分布,显示为管道截面流动图像。理论研究表明,该方法是实现生产测并成像化测量的一种有效途径。更多还原

【Abstract】 Based on the considerable impedance difference between oil and water in production and operation,an array impedance imaging method is presented.By measuring the electrical voltage variation in given current execution mode,using an image reconstruction algorithm,the cross-sectional oil-water two phase flow image can be obtained.The theoretical analysis shows that it is feasible.更多还原
