【摘要】：针对非均质底水凝析气藏水平井出水规律复杂及有效控水的问题,以中国西北部底水凝析气藏为研究背景,归纳出水平井钻遇储层的6种不同构型特征,以30口底水凝析气藏水平气井实际生产动态数据为支撑,分析了不同水平气井见水规律。分析表明,底水凝析气藏水平气井见水特征主要表现为3种类型,以此为基础,总结出不同见水规律与所钻遇储层特征的对应关系,可根据气井见水规律反演对应的储层构型特征。实例表明,采用该对应关系判断储层特征与实际储层特征的符合率达到82%以上,研究成果为底水凝析气藏合理避水开发及提高气藏采收率提供了科学的方法和理论依据。
[Abstract]:In view of the complex rule of horizontal well water and effective water control in heterogeneous bottom water condensate gas reservoir, six different configuration characteristics of horizontal well drilling and meeting reservoir are summarized with the background of bottom water condensate gas reservoir in northwestern China. Based on the actual production performance data of 30 horizontal gas wells in bottom water condensate gas reservoirs, the water breakthrough law of different horizontal gas wells is analyzed. The analysis shows that the water breakthrough characteristics of horizontal gas wells in bottom water condensate gas reservoirs are mainly three types. On the basis of this, the corresponding relationship between different water discovery laws and the reservoir characteristics in drilling is summarized, and the corresponding reservoir configuration characteristics can be retrieved according to the gas well water breakthrough law. The example shows that. The coincidence rate between reservoir characteristics and actual reservoir characteristics is more than 82%. The research results provide a scientific method and theoretical basis for reasonable water diversion development of bottom water condensate gas reservoir and enhancement of gas reservoir recovery.

【正文快照】： 0引言底水凝析气藏在开发过程中会出现很多矛盾,气井见水即为不可避免的问题之一,气井见水后直接影响气井产量甚至停产,同时影响气田整体开发效果[1-2]。由于储层物性的差异,位于不同位置的气井表现不同的见水特征[3-5],明确气井出水规律及充分认识储层特征对合理控水治水至关
