雅克拉—大涝坝凝析气藏属于深层、高温高压凝析气藏,在开发过程中气井不同程度的产出凝析水,特别位于高部位气井凝析水产出量较高。由于凝析气藏烃类组分自身的变化较为复杂,若组分中富含气态凝析水,对相态变化、开发特征就会产生较大的影响。鉴于此,该文从相态变化以及微观渗流方面展开研究,分析凝析水产出规律及产出机理,以及凝析水对雅—大凝析气藏开发动态的影响。研究成果对雅—大凝析气藏的开发动态分析有一定的指导作用。
The Yakela-Dalaoba Gas Condensate Field has accumulations deep buried with high temperature and pressure.During development,condensate water was found in gas wells in different extent,eSpecially in wellsin higher positions.Hydrocarbon components of gas condensate reservoirs areGated.Condensate water vapor in the component may influence facies changes and developmentcomplicharacteristics greatly.From the aspects of facies change andmicroseepage,the law and mechanism ofcondensate water generation were analyzed.The influence of condensatewater on the exploration of theYakela-Dalaoba also studied.The research may guide the dynamic analysis Gas Condensate Fieldof the gas field.
