Chinese Abstract

研製了一種可用於油藏監測的3分量光纖加速度傳感器。該傳感器通過3個單方向傳感單元分別獲得3個正交方向上的被測加速度分量,每個傳感單元是一質量-彈簧系統,通過波紋管與順變材料構成複合彈性體,並採用光纖干涉結構將被測加速度通過解調光纖中的相位變化反映出來。實驗數據表明,該加速度傳感器具有良好的線性度、一致性和穩定性。系統的工作頻帶範圍為10 Hz至800 Hz,其軸向靈敏度為38 dB re rad/g,交叉法去敏度達到32 dB re rad/g,最小可檢測加速度為39.3 μg/Hz(上標 1/2)。

English Abstract

A 3-component (3-C) fiber-optic accelerometer suitable for well logging is presented. The accelerometer can accomplish the 3-C measurement by multiplexing three unidirectional sensing elements, in which every one is based on a push-pull mass-spring structure. Experimental results show good linearity, consistency and stability. The suitable measurement frequency range of the system is between 10 Hz and 800 Hz. The difference between on-axis sensitivity and cross-sensitivity is 32 dB re rad/g, and minimum detectable level is 39.3 μg/Hz(superscript 1/2)
