摘要: 针对凝析气藏中凝析气反凝析油地层水之间的相态变化极其复杂,常规相平衡计算只考虑了凝析气与反凝析油之间相态变化的问题,开展了流体组成中考虑气态凝析水组分的流体PVT实验。模拟计算了过饱和水凝析气体系的CCE和CVD实验过程,研究认为:过饱和水的存在会对体系的CCE和CVD过程造成明显的相态影响。对多相流体复杂相平衡研究具有重要意义。

Abstract: In accordance with the complexity of phase state characteristic of gascondensatewater in gas condensate reservoir, and the phase state between condensate and gas is considered in conventional phase equilibrium calculation, the PVT(pressurevolumetemperature) experiment in which the gaseous condensate water component is included in the fluid′s composition is carried out. The CCE(constant composition expansion) and CVD(constant volume depletion) experimental procedures for gas condensate system which includes the oversaturated water are simulated, the result shows: because the existence of oversaturated water in gas condensate system, the phase state characteristic will obviously influence CCE and CVD. The consequence is very important to research the complicated multiphase fluid phase equilibrium.

Key words: gas condensate reservoir, oversaturated water, phase state simulation, CCE experiment simulation, CVD experiment simulation.
