摘　　要：油气混输管式捕集器工艺计算原则上应考虑两方面因素 ,即来流在管束分离段内应转变为分层流型 ,以便于气液分离 ;同时 ,储存段应能容纳清管工况下产生的积液 ,使液体不致于从气体出口流出。基于这两条原则进行分离段和储存段的设计计算 ,并动态模拟当 1/ 10 0 0概率最大液塞进入捕集器时液位和压力的动态变化 ,据此确定捕集器最优结构尺寸。基于上述原理 ,编制了管式捕集器结构尺寸优化设计软件 ,软件尚需实际工程的考核和完善。In the technological calculation of the tubular-type slug catcher for oil-gas transmission, two factors should be taken into account. The first one is that the inflow have to be transformed into stratified flow so as to separate gas and liquid. The second one is that the storage section requires accommodating the liquid volume produced during the pigging period. Based on these two principles, design and calculation of the separation section and storage section are conducted, and dynamic simulations of the change of the liquid level and pressure in case of the maximum liquid slug 1 in 1000 entering the slug catcher are implemented. Thereby the optimum size of the slug catcher is determined. On the basis of the above-mentioned principle, the software of optimum design of the size of the tubular-type slug catcher is programmed.
