摘要：Pipeline blockage, which results from solid and hydrocarbon deposition caused by changes in pressure, temperature, or composition, is a critical issue in oil and gas production and transportation systems. Sometimes blockage, which extends several miles in the long-distance pipe, can be approximated as a pipe with a smaller diameter. While the earlier work focused on treating pipeline blockage as a choke for its limited size and length, this study attempts to analyze the relationship between the pressure distribution and the blockage size/length when analyzing the blockage characteristics under different situations. This paper explores the distribution of pressure and pressure gradient around the pipeline blockage under different operating conditions. Three-dimension (3D) computational fluid dynamic (CFD) simulations under steady-state are carried out to examine the effects of blockage diameter, blockage length, and blockage location. The relationship between the pressure drop and blockage characterization is predicted. A forecasting model for blockage sensing and localization is proposed. Lab experiments are conducted to compare the simulation results to measured data and the accuracy of forecasting model is evaluated. The study indicates that CFD simulation results match the experiment data and the model is a useful tool in detection of pipeline blockage.
