采油厂污水罐排泥现场探测实验及数值模拟仿真研究

In-situ Detection Experiment and Numerical Simulation Study of Oil Production Plant Sewage Tank Mud Discharge

针对储罐清砂困难的问题,目前,胜利油田的污水罐排泥以传统静压排泥方式为主,由于其起步较早、适用范围广、所用设备简单的优点,该技术成为油田应用最多的污水罐排泥技术。近年来,各类重型机械等新型排泥技术逐渐被引入和推广,由于其良好的排泥效果,现在已经进入了较为广泛应用阶段。但是目前没有有效的数值模拟仿真技术对排泥过程进行分析,为此,通过对现场罐底沉积物进行探测,利用Fluent进行了流场仿真,同时对罐底结构进行改进,并对改进方案进行分析,仿真结果对采油厂水罐分析改进提供了有力的支撑。

In response to the difficulties of sand cleaning in storage tanks,the current practice of mud discharge in the sewage tanks of Shengli Oilfield is primarily based on traditional hydrostatic mud discharge due to its early inception,wide applicability,and the simplicity of the equipment used.As a result,this technology has become the most widely applied mud discharge technique in the oilfield.In recent years,various new mud discharge technologies,including heavy machinery,have been gradually introduced and promoted.Owing to their effective mud removal results,these technologies are now entering a stage of more extensive application.However,there is currently no effective numerical simulation technology to analyze the mud discharge process.To address this,sediment at the bottom of the site's tank was detected,and a Fluent flow field simulation was conducted.Improvements were made to the tank bottom structure,and the improvement plans were analyzed.The simulation results provide robust support for the analysis and enhancement of the oil extraction plant's water tanks.
