Research progress on failure prediction and prevention technology of non-metallic pipes in oil and gas fields
The corrosion and perforation risk of metal pipes in oil and gas fields is becoming more and more serious,and pipeline leakage accidents often occur.Non-metallic pipes such as glass steel pipe,steel skeleton reinforced polyethylene composite pipe and flexible composite pipe are gradually favored in oil and gas field development and production system for their good corrosion resistance and applicability.However,due to the aging effects of internal and external pressure load and medium corrosion during the long-term service of the pipe,various failure problems such as matrix cracking,pipe body brittle,fiber/matrix interfacial debonding,interlayer separation and so on need to be solved urgently.Based on this situation,this paper summarized the characteristics,application and failure causes of non-metallic pipelines commonly used in oil and gas fields,as well as the detection and positioning,non-destructive testing technology,risk assessment and life prediction methods of non-metallic pipelines,and put forward relevant suggestions on the prevention of non-metallic pipeline damage and failure in pipeline manufacturing,construction,operation,application,maintenance and key technologies.The paper also prospected the key issues of non-metallic pipeline failure prevention technology to provide effective support for the relevant research of non-metallic pipeline failure prediction methods and prevention and control technologies.
