摘要
为了更好地进行油、气井的生产,预测水平井筒中和混合管线中油、气、水混合物多相流的动态,以机理性研究为指导,通过实验及数学方法来讨论流动型态的转变及判别。在层状流流动模型的基础上,得到了水平管中气液两相流流型转变的部分判别准则。研究表明,在一定的范围内,该准则具有良好的流型识别能力,可用于描绘水平管中或水平井筒中气液两相流流型的变化规律,来指导油、气井的生产;同时,也为以后的研究提供了重要的理论依据。
The change and recognition of flow pattern are discussed through experimental and mathematical methods with the guidance of mechanism study to predict the behavior of multiphase flow of oil-gas-water mixture in horizontal wellbore and pipeline. Partial recognition criterion of flow pattern change for gas-liquid two-phase flow in horizontal pipe has been obtained based on a laminar flow model. The study shows that with certain limit, this criterion is very good for recognizing flow pattern and can be used to describe the changes of gas-fluid two-phase flow pattern in horizontal pipe or well to guide oil and gas well production and also provides important theoretical basis for future study.
