摘要
本文建立了描述钻井气侵期间井眼气液两相流偏微分方程组,该方程组既考虑了不同渗透率的储层与储层钻开不同厚度下的气体侵入井眼情况,也给出了这种情况下该偏微分方程组的求解方法。利用实验数据进行了模拟,揭示了环空气液两相流型与流动参数变化特征,据此,能够为安全有效地井控提供理论基础。
The paper constructs two-phase gas-liquid flowing finite differential equation group which considers different permeability and exposed length of gas reservoir during gas kick and acquires the solution of the equation group. This paper also shows the two-phase gas-liquid flowing characteristics considering different gas reservoir conditions using experiment data and gives the basic theory for well-control safely.
