Oil Gas Well Sensing Optical Cable

Oil Gas Well Sensing Optical Cable (DOSC) is dedicated cable for downhole distributed monitoring, widely deployed in DAS and DTS optical fiber well logging. It adopts 316L / Alloy 825 stainless steel tape armor with 0.71mm thickness and compressive strength of 207 MPa, supporting continuous operation within -40℃ ~ 300℃. The 0.3% excess fiber length prevents optical fibers from mechanical stress deformation under downhole service conditions. The hydrogen-absorbing filling compound stabilizes optical attenuation, mitigates hydrogen-induced loss and extends service lifespan. For operating temperature above 150℃, proprietary three-layer construction with 0.04-inch fluoroplastic intermediate layer is adopted to strengthen high temperature resistance and corrosion protection.   It can be run into wells synchronously with High Temperature Steel Tube Cable to build full-range downhole data acquisition network. Cooperated with Well Logging Cable for multi-parameter logging, it works alongside C…
