摘　　要：采用较高频率的短波可以使电磁波较易穿透非金属容器的阻隔而作用到被测介质上;利用谐振电路的特点可以测量出微小的电容变化并保证有足够的信噪比。为了减小测量系统的自身天线辐射干扰,要选择适当的振荡频率并加装去除干扰器件以保证测量数据的稳定可靠。将这一方法用于测量定向模型井筒环形空间中岩屑沉积厚度,收到了良好的使用效果。This paper presents a method for measuring the solid con-teut in water inside a non-metallic container, especially measuring the settling thickness of cuttings in the aunulus of a directional well. The short wave with a higher frequency can be used for the detection, because this kind of short wave can easily penetrate the wall of non-metallic container to reach the solids in it. A special resonance circuit has been designed. It can detect the tiny variation in solid content and get higher signal noise ratio. In order to minimize the radiation interference from antenna, the circuit must oscillate in a proper frequency and an interference eliminating unit must bs added.
