摘要:
为对深水高压气井测试地面流程中的节流油嘴段的温压场及水合物生成情况进行研究，采用数值模拟的方式对整个节流管路进行气体流动特性分析。并利用P-T图回归公式法，得出不同温压场条件下的水合物生成情况，进行水合物生成范围对比。结果表明：针阀出口后端气体速度随着管路入口压力和针阀直径的增大而增大，随管路出口压力的增大而减小，而气体温度随管路入口压力、管路出口压力、针阀直径的变化趋势与之相反。管路入口压力的递增、管路出口压力的递减以及针阀直径的递增，都会导致针阀突变径处的速度场、温压场波动更加剧烈，并使得水合物生成范围扩大。
Abstract:
In order to study the temperature-pressure field and hydrate generation of the throttle nozzle section in the ground process of deepwater high-pressure gas well test,the gas flow characteristics of the entire throttle pipeline were analyzed by numerical simulation.The generation of hydrate under different temperature-pressure field conditions was obtained by using the regression formula method based on P-T graph,and the range of hydrate generation was compared.The results showed that the velocity of gas at rear end of needle valve outlet increased with the increase of pipeline inlet pressure and diameter of needle valve,and decreased with the increase of pipeline outlet pressure,while the change trend of gas temperature with the pipeline inlet pressure,outlet pressure and diameter of needle valve was the opposite.With the increase of pipeline inlet pressure,the decrease of pipeline outlet pressure and the increase of diameter of needle valve,the fluctuation of velocity field and temperature-pressure field at the location with abrupt change of the diameter of needle valve would be more violent,and the range of hydrate generation would enlarge as well.
