微通道管路中硫酸钡沉积动力学分析
|
摘要
为研究油田注水系统管道中硫酸钡垢的沉积行为,采用压差法和火焰原子吸收分光光度法对微通道管路中硫酸钡的沉积过程进行测定分析,建立了相关的沉积动力学模型,考察了不同因素对反应动力学系数(ka)和管路沉积系数(β)的影响。结果表明,ka和β随反应的进行逐渐增大。当管路增长、流量增大、BaCl_2和Na_2SO_4初始浓度增加时,ka增大;β随着管路增长和流量增大呈非线性增加,随浓度增大线性增加。温度升高,β增幅增加,ka在反应初期无明显变化,在反应后期增加。根据实验数据拟合得到ka和β的相应关联式,由此计算得到的相应值与实验测量值大致相符;由简化的硫酸钡沉积动力学模型计算的管路出口钡含量与实验测量值基本吻合,说明基于假设前提下建立的硫酸钡沉积动力学模型是合理的。
In order to study the deposition behavior of barium sulfate scale in pipelines of oilfield water injection system,the deposition process of barium sulfate in microchannel pipelines was measured and analyzed by differential pressure method and flame atomic absorption spectrophotometry,and a related depositional dynamics model was established. The influence of different factors on the reaction kinetic coefficient(ka)and the pipeline deposition coefficient(β)was investigated. The results showed that ka and β gradually increased with the reaction. It indicated that ka increased with increasing pipeline,flow rate,and initial concentration of Ba Cl2 and Na2 SO4. β had a nonlinear increase with increasing pipeline and flow rate,and had a linear increase with increasing concentration. With the increase of temperature,the increment of β increased. While ka did not change significantly in the early stage of the reaction and increased in the later period of the reaction. Equations of ka and β were obtained by fitting the experimental data,and the corresponding calculated values were roughly in accordance with experimental measurements. The concentration of barium at the exit of pipeline calculated from established simplified model was basically consistent with experimental measurements,which illustrated that it was reasonable to explain the deposition kinetics model of barium sulfate reaction system based on assumptions.
