Abstract
Blockage often occurs in gas-condensate natural gas pipelines. A transient compositional multiphase hydrodynamic model for transient gas-condensate two-phase flow and a hybrid high-resolution higher-order TVD/Roe scheme are used to investigate wave propagations in gas-condensate natural gas pipelines with blockages under transient excitations. The wave propagation behavior at one of the two ends or one or more specified locations with known blockages at given locations along a pipeline is monitored. The location of a blockage along a pipeline may change, and the corresponding wave propagation behavior is simulated. The effect of severity and length of a blockage on the characteristics of wave propagation behavior is investigated. A double-test approach is proposed to determine the length of a blockage in a pipeline. Also, multiple blockages with different relative locations along a pipeline are investigated. This study is intended to develop a blockage detection technique for gas-condensate natural gas pipelines using wave propagation characteristics.
