中文摘要:
      在海洋油气开发中,水下节流阀作为水下生产系统的重要组成部分,用于调节生产单元的流量,冲蚀是其主要失效因素之一,因此研究水下节流阀冲蚀失效的影响机理尤为重要。以某笼套式角型水下节流阀为研究对象,建立了水下节流阀的三维流体域模型,采用ANSYS Fluent的标准k-ε湍流模型、DPM离散相模型和Generic冲蚀模型进行了不同开度下的流场数值模拟计算和冲蚀分析,研究了流场环境参数对冲蚀的影响。对水下节流阀流场数值模拟结果进行分析,得到了水下节流阀流场内流速、压力的分布规律。对不同开度下水下节流阀的冲蚀数值模拟结果进行分析,发现节流孔处是冲蚀最为严重区域,得到了冲蚀率随开度的变化曲线。对不同流场环境参数下水下节流阀的冲蚀数值模拟结果进行分析,得到了最大冲蚀率和最大冲蚀深度随流场环境参数的变化规律。根据数值模拟的分析及结论可以对水下节流阀结构进行改进,并在油气生产中对流场环境参数进行控制,提高海洋油气开发的经济效益。
英文摘要:
      In offshore oil and gas development, subsea choke valve is an important part of subsea production system, which is used to regulate flow rate of the production units, and erosion is one of the main failure factors. Erosion is one of the main failure factors, so it is particularly important to study the influence mechanism of subsea choke valve erosion failure. A three-dimensional fluid domain model of a cage-cased angular subsea choke valve was established. The flow field numerical simulation and erosion analysis under different opening degrees were carried out by using the standard k-ε turbulence model, DPM discrete phase model and Generic erosion model of ANSYS Fluent, and the influence of environmental parameters of flow field on erosion was studied. By analyzing the numerical simulation results of subsea choke valve fluid domain, the distribution law of velocity and pressure in subsea choke valve fluid domain was obtained. By analyzing the numerical simulation results of subsea choke valve erosion under different opening degrees, it is concluded that the most serious erosion area is at the throttle hole, and the curve of erosion rate varying with opening degrees is obtained. The numerical simulation results of subsea choke valve erosion under different fluid domain environmental parameters are analyzed, and the variation rules of maximum erosion rate and maximum erosion depth with fluid domain environmental parameters are obtained. According to the analysis and conclusion of numerical simulation, the structure of subsea choke valve can be improved, and the fluid domain environmental parameters can be controlled in oil and gas production, and the economic benefits of offshore oil and gas development can be improved.
