油气混输管道段塞流模拟及段塞流捕集器设计研究

Study on simulation of slug flow in oil-gas mixed transportation pipeline and design of slug catcher

油气混输管道经常出现段塞流,泰梯尔-杜克勒-巴衲(TDB)流态图将油气两相流动分为五种流态,段塞流可分为三种类型。石油-天然气(OLGA)软件可模拟运行期段塞流及清管期段塞流。油气混输管道下游应设置段塞流捕集器,以确保下游设备正常运行。

Slug flow often occurs in oil-gas mixed transportation pipeline;Taitel-Dukler-Barnea(TDB)flow pattern diagram divides oil-gas two-phase flow into five flow patterns;Slug flow can be divided into three types.OIL-GAS(OLGA)software can simulate slug flow during operation and pigging.Slug catcher shall be set at the downstream of oil-gas mixed transmission pipeline to ensure the normal operation of downstream equipment.
