摘要: 为探究深海卧管⁃悬链线系统内立管管内流动特性,针对南海某油气田,通过数值模拟分析了管径、卧管入口处总流量、含水率(质量分数)和出口压力对管内流动特性参数的影响规律。结果表明,以管内流动状态发生转变的位置为界限,各影响因素对管内流动状态参数的影响表现出不同的变化规律,但是管内沿程温度分布基本不受相关因素的影响;4个因素对管内流动特性参数的影响存在明显的阶段性:管径的影响分为D=0.06~0.12 m和D=0.12~0.50 m两个阶段,卧管入口处总流量的影响分为Q=0.001~0.030 m3/s和Q=0.100~0.300 m3/s两个阶段,含水率的影响分为w=10%~25%和w=25%~30%两个阶段,出口压力的影响分为0~5.0、5.0~7.0 MPa和7.0~10.0 MPa三个阶段。

Abstract: In order to explore the flow characteristics of vertical pipe in the deep⁃sea horizontal pipe⁃catenary system, in this paper, aiming at an oil and gas field in the south China sea, the influence of diameters, total flow rate, water cut and outlet pressure were simulated. The results show that the position of the flow state in the pipe is the boundary, and the influence of each influencing factor on the flow state parameters in the pipe shows different changes, but the temperature distribution along the pipe is not affected by the relevant factors; From the perspective of the research scope of the above four parameters, the influence process of each parameter is divided into different stages. The influence of pipe diameter is divided into two stages: D=0.06~0.12 m and D=0.12~0.50 m, the total flow of Q=0.001~0.030 m3/s and Q=0.100~0.300 m3/s, the water content of w=10%~25% and w=25%~30%, and the outlet pressure is divided into three stages, including 0~5.0, 5.0~7.0, 7.0~10.0 MPa.
