FIBER-OPTIC CABLE FOR MEASURING TEMPERATURE DISTRIBUTION IN STEAM-FORCING WELLS

摘要

FIELD: optical cables engineering.;SUBSTANCE: cable has optical fiber placed in sealed metallic pipe. Protective cover is a metallization layer closely adjacent to fiber as well as glass-wire winding encircling metallization layer. Pressurized metallic pipe is filled with inert gas.;EFFECT: higher reliability and lower costs.;8 cl, 1 dwg
