多相管流计算方法在计算水淹气井压力梯度中的应用

Application of Calculation Method of Multi-Phases Tube Flow to Calcu-lating Pressure Gradient in Watered-out Gas Well

本文提出一种新的多相管流计算方法,这种方法大部分基于流动力学的理论分析。经过6井次的计算应用,平均相对误差为-1.63％,标准离差为2.40％,证明是一种可靠的两相流计算方法。

This paper presents a new calculation method of multi-phases tube flow. Through the calcu-lation and application of six well-times, the average relative error is-1.63 and the standard devl-ation is 2. 4O%, which proves that it is a tellable method for two-phases flow calculation.
