摘要: 应用气井、凝析气垂直管流压降计算常用的相关模型:单相模型(平均压力、平均偏差系数法)、修正单相模型、Hagedorn-Brown模型、Duns-Bos模型,对雅克拉白垩系凝析气井15井次的测试流压数据进行了拟合计算;并根据计算结果把本区垂直管流压降计算划分为无、有边(底)水侵入两个阶段,并在这两个阶段中分别用不同的模型计算,在模型适用性上给予了充分论证.

Abstract: The single phrase model (average pressure deviating coefficients method),modified single phrase model,Hageddorn-Brown model,Duns-Ros model are applied to compute vertical flowing pressure gradients of gas wells and condensate-gas wells.The fifteen wells testing flow pressure data of the Yakela Cretaceous condensate-gas wells are matching-competed.Based on these results,the vertical flowing pressure gradients of the region are divided into two stages:no border (bottom) water invading and border (bottom) water invading.Different models are used to compute respectively,which meanwhile demonstrated the models applicability.
