摘要:

油井采出原油中含有泥沙、垢等颗粒物,在管输过程中颗粒物与原油中的蜡分子协同沉积,导致管道输量降低,严重时可能造成管道堵塞,影响原油管道安全输送。对掺垢蜡沉积物进行了屈服应力测试实验和显微特性实验;对室内聚乙烯管道进行了清管实验;基于清管实验结果,利用π定理建立了清管效率预测模型。结果表明,碳酸钙垢对蜡沉积物强度的影响存在临界垢质量分数;沉积物中含垢,会提高清管器的蜡层破坏力和清管效率;通过室内实验和第三方文献实验数据,验证了所建立的模型。

关键词: 屈服应力, 蜡沉积物强度, 临界含垢质量分数, 清管实验, 清管效率预测模型

Abstract:

The crude oil produced by oil wells contains sediment, scale and other particles, which are deposited together with the wax in the process of crude oil pipeline transportation. It leads to a decrease in pipeline throughput, and may cause pipeline blockage and affect the safety of transportation in severe cases.The yield stress test and microscopic characteristic experiments show that there is a critical scale containing ratio in wax deposits of the influence of calcium carbonate scale on the strength of wax deposits. And it is found that the wax deposits containing scale will increase the breaking force on the wax layer and the pigging efficiency of the pig through the indoor pigging experiment of polyethylene pipeline. Based on the data of pigging experiment, a prediction model of pigging efficiency was established by using the π theorem. The model was validated by indoor experiments and third?party literature experimental data.

Key words: Yield stress, Strength of wax deposits, Critical scale content mass fraction, Pigging experiment, Prediction model for pigging efficiency
