稠油热采注蒸汽分配器的流场数值模拟

Flow Field Numerical Simulation of the Steam Injection Distributor in the Thermal Recovery of Heavy Oil

了解蒸汽分配器内的流场分布,比较一分三立式蒸汽分配器与一分三球形蒸汽分配器的分配效果。通过Fluent对一分三立式蒸汽分配器与一分三球形蒸汽分配器内部的流场进行数值模拟,分析分配器内密度分布、气相体积分布与速度场对蒸汽分配效果的影响。数值模拟结果表明,在蒸汽的干度与流量分布过程中,一分三球形蒸汽分配器要优于一分三立式蒸汽分配器。建立的一分三球形蒸汽分配器可为实际现场作业及高温高压球形分配器的建造提供参考。

To understand the flow field distribution inside the steam distributor,and to compare the distribution effect of the three vertical steam distributor and the three spheres steam distributor,the inside flow field was simulated by Fluent and the effect of density distribution,gas phase distribution and velocity field on steam distribution was analyzed.From the results of numerical simulation,it can be seen that,in the process of steam dryness and flow distribution,three ball steam distributor is better than three vertical distributor.The establishment of a three spherical steam distributor provides a reference for the construction of actual field operations and high temperature and high pressure spherical distributor.
