摘要
基于油、气与水的导电特性和介电特性差异，提出一种多相管流成像测井方法，可测量并求出油井内多相流体流动的截面图像．通过分析油井内流体中电磁场的特性，提出新的成像测井方法，并用自行研制的环状阵列式测量探头进行实验，验证了方法的可行性．
A method of electromagnetic imaging logging in multiphase pipe flow is persented, which is based on the electric property differences between oil, gas, and water to measure and compute the images of multiphase flowing section in oil wells. Through analysis of the electromagnetic field properties in oil well fluid, the imaging logging method is produced, and itS practicability is inspected using the experiment results by the self-mantifactured probe.
