摘　　要：由于水、油介电特性差异较大,电磁波在不同含水率的油水混合介质中传播的相位系数有很大不同,通过测量电磁波在油水混合介质的同轴线内相位系数获取油水混合介质的含水率,并研制出了一种新型原油含水率仪。针对油田实际情况,对该仪器进行了动静结合的实验研究。实验表明,该仪器能够实现油井含水率全范围的连续测量,且具有较高的分辨率和准确度,解决了准确测量油田原油高含水率这一难题。There is a big difference between dielectric property of water and oil, so the phase constant of oil/water mixture flows (which is measured by a coaxial line) is quite differente, when electronmagnetic wave travels in it. This coaxial line is used as a sensor to measure the water content. The test study has been carried for this instrument with dynamic and static state for the practice of oil field. It can realize continuous measurement of water content in oil well with high resolution and accuracy, and resolve the difficulty of measuring water content in high water cut oil field.
