abstract = "Real-time monitoring of dynamic liquid-level is very important in oilfield. A novel method combining pressure measurement and temperature profile measurement is proposed in this paper to measure dynamic liquid-level of oil-well in real-time. A fiber Bragg grating pressure sensor based on an eccentric-pushrod structure is used to measure downhole pressure, and the multimode fiber is used to measure temperature profile. The initial position of the dynamic liquid-level can be determined by the inflection point of the temperature profile. The density of the liquid in the well is calculated from the initial pressure and the dynamic liquid-level. Base on this data, the real-time position of the dynamic liquid-level can be obtained only by using the pressure data. Experimental results show that the method that combining pressure measurement and temperature profile measurement can provides real-time and accurate monitoring of oil-well dynamic liquid-level data.",
