Abstract:

The service environment of Yanchang oilfield was researched. The corrosion environment of the oil and gas area of Yanchang group is different, the summer rainstorm is frequent and the landslide debris flow is easy to occur. The theoretical analysis and pilot test of pipeline performance have been carried out. We suggest that the steel pipeline, t FRP pipeline and the flexible composite pipe for high pressure transmission can be used in Yanchang group. The combined application strategy of steel pipeline, FRP pipeline and flexible composite pipe for high pressure transmission was proposed and verified. The results show that the combined application strategy effectively slows down the pipeline corrosion problem, reduces pipeline leakage accidents caused by accidental landslides, and reduces environmental pollution accidents caused by accidents such as pipeline corrosion and leakage. The tracking and analysis of pipeline combined application strategy for up to 5 years, the results show that the pipeline combined application strategy is more economical. It is concluded that the combined application strategy of steel pipelines, FRP pipelines and Flexible Composite Pipe for High Pressure Transmissions can ensure smooth operation of pipelines and save costs in the development of oil and gas fields, and it is recommended to popularize.
