摘要
钻探过程中井底钻具的振动及倾角是调控钻探工艺及轨迹的重要参数,有必要实时监测.基于摩擦纳米发电机,提出了一种新型的多功能自发电井下传感器,可同步实现振动频率及倾角的测量.试验表明,该传感器测量振动频率及倾角范围分别为 0～11 Hz及 0～90°,测量误差均为±5%,可在温度0～100℃及湿度 0～90%的工况环境下正常工作.与传统的井下传感器相比,该传感器可同步监测振动频率和倾角,有效缩减了传感器数量,同时还具有自发电功能,有效减轻了井下供电压力.
Abstract
The vibration and inclination angle of the bottom hole drilling tool during the drilling process are important parameters to control the drilling process and trajectory,and it is necessary to monitor them in real time.A new multifunctional self-generating underground sensor was proposed based on triboelectric nanogenerators,which can simultaneously measure vibration frequency and inclination angle.The test results show that the sensor measures the vibration frequency and inclination angle in the range of 0-11 Hz and 0-90°,respectively,the measurement error is±5%,and can work normally in the working environment of 0-100℃and 0-90%humidity.Compared with traditional downhole sensors,this sensor can monitor the vibration frequency and inclination angle synchronously,effectively reducing the number of sensors,and also has the function of self-generating,which effectively reduces the pressure of underground power supply.
