The software"Stoner Pipeline Simulator"(SPS) is a software system with high accuracy recognized worldwide for long distance oil and gas pipeline design,parameter calculation and automation control simulation of the whole pipeline.Applied is the software for analog calculation of certain crude oil pipeline and found is an anomaly within certain oil transportation temperature range,that is,friction between stations will increase as the transportation temperature increases.Studied is the anomaly and introduced are common calculation methods for factors of friction resistance and calculation method for built-in factor of friction resistance of the software SPS.Study and analysis results showthat the weighted factor of friction resistance will increase as the temperature increases because curvature of friction factor curve ofturbulent flowin the fluid is more than that oflaminar flow.
