适于温度300℃、压力50MPa的测井传感器连接封装装置,具备如下全部特征:包括光纤传感器、传感光缆和光缆压套,光纤传感器包括伸出的第一光纤抽头,传感光缆穿过光缆压套,伸出部分为第二光纤抽头;第一光纤抽头、第二光纤抽头末端固定连接,且连接点附近光纤抽头部分仅包括光纤纤芯和包层。第一光纤抽头和第二光纤抽头外围整体包覆有内径大于完整光纤外径的密封套,从而在密封套和连接点之间形成光纤冗余空间。本发明对光纤连接点附近的光缆剥离了被覆层,形成一个光纤冗余空间,能让光纤接头不受外力和应力的作用,有效的保护连接点;保证传感传感器与传感光缆的接头有良好的机械强度和抗弯折能力。
Suitable for logging sensors with a temperature of 300 ° C and a pressure of 50MPa, the packaging device has all the following features: an optical fiber sensor, a sensing optical cable and a cable clamping sleeve. The optical fiber sensor includes a protruding first optical fiber tap. And the protruding part is a second optical fiber tap. The first optical fiber tap and the second optical fiber tap end are fixedly connected, and the optical fiber tap part near the connection point only comprises the optical fiber core and the cladding. The periphery of the first optical fiber tap and the second optical fiber tap is integrally covered with a sealing sleeve with an inner diameter larger than the outer diameter of the complete optical fiber so as to form an optical fiber redundant space between the sealing sleeve and the connection point. In the invention, the coating layer is peeled away from the optical cable near the optical fiber connection point to form an optical fiber redundant space, which can make the optical fiber connector not be subjected to the external force and the stress and effectively protect the connection point; and ensure the connection between the sensor sensor and the sensing optical cable Good mechanical strength and bending resistance.
