流体相态研究在凝析气藏开发中的应用

THE APPLICATION OF LIQUID PHASE STATE STUDY IN THE DEVELOPMENT OF CONDENSATE GAS RESERVOIR

凝析气藏是一种特殊类型油气藏,对该类气藏的开发特别是在高液烃含量凝析气藏的开发过程中,对流体相态研究尤为重要。指出通过流体相态研究能够取得凝析气藏不同开发过程中流体组份变化情况,从而确定较好的开发方式;在开发过程中定期取得流体样品并进行相态特征和流体组份变化规律研究,可指导开发方案实施及调整方向。认为流体评价研究在整个凝析气藏开发过程中具有广泛的应用性。

Condensate gas reservoir is a special type reservoir. Fluid phase state study is very important to the development of this kind reservoir, especially to high liquid hydrocarbon content condensate reservoir. Through the study of fluid phase state, the fluid composition variance of the condensate gas reservoir during the different development phase can be acquired, thus better development mode can be decided. Fluid sample can be acquired periodically and the study for the phase characteristic and fluid composition variance can be carried out to direct the plan implementation and direction adjustment. Fluid evaluation study can be widely used and has an important role in the development of condensate gas reservoir.
