水平井井筒流动规律研究 摘要：水平井的优越性如今已成不争的事实，世界在短短几年中竟相钻成数千口水平井就是证明。在水平井实际生产时，井筒流动和油藏渗流是一个相互影响、相互作用体，合理描述水平段的流体流动规律和压降关系及垂直段流体流动规律，对确定水平段的长度、准确预测水平井产量等有重要意义。合理准确的掌握水平井井筒流体流动规律，不仅对水平井的生产及生产过程中调整有着重要的指导意义，而且对油藏整体的合理开发提供着重要的依据。研究水平井井筒压力分布、井筒流态及井筒压降模型；介绍水平井压降分布及油藏模型。同时研究水平井垂直段井筒流动规律，介绍气液两相流模型、流型的划分及转换；写物性参数计算、垂直井筒流动模型计算和压降模型计算。通过对比，分析，计算，总结，最终得结论。 关键词： 水平井 ； 井筒 ； 流动型态 ；三相流 Horizontal well chamber mobile rule Abstract: The advantages of horizontal wells has become an indisputable fact that today, actually the world in just a few years with thousands of horizontal wells drilled is proved. Actual production in horizontal wells, the wellbore flow and reservoir seepage is a mutual influence, interaction body, a reasonable description of the fluid flow in horizontal and vertical section of the pressure drop of fluid flow relations and law in determining the length of horizontal section, an accurate prediction horizontal wells yield significance. Reasonably accurate grasp of horizontal well bore fluid flowing in, not only for the horizontal well production and to adjust the production process has an important significance, but also the reasonable development on the reservoir to provide an important basis. This article was open hole horizontal well in the distribution in the reservoir, horizontal wells in reservoirs with bottom water in the distribution model and reservoir model of shaft, horizontal section pressure drop model, the vertical wellbore pressure drop model and the horizontal well gas-water flow between the three-phase conversion. Combined with a large number of oil production and a large number of instances of the mathematical model, by contrast, analyze, calculate, sum up the end with a conclusion. So as to provide a reliable oil field development, and scientific and reasonable development program.
