中文摘要	Fractures in the rich gas transportation pipeline was analyzed based on a crack propagation pipeline model for rich gas transmission. A multi-parameter equation of state which includes the rich gas phase transition was used to calculate the pressure plateau occurring during the rich gas phase transition. A three-stage linear pressure model was used to study the pressure distribution around the crack tip. The model was validated against full-scale burst tests and numerical simulations of the propagation phase. The model shows that the fractures are more severe with the increase volume percentage of the natural gas liquids, namely the cracks will run a long distances before being arrested.
