摘要: 凝析气藏是一种特殊气藏类型。在衰竭式开发过程中,不可避免发生反凝析现象,增加地层中液相的饱和度,降低气井产能。在白庙凝析气田代表井白52井单井模拟近井地带反凝析饱和度分布基础上,结合试井解释结果和拟稳态气井产能方程,提出定量评价近井地带反凝析污染对气井产能影响的方法,对分析凝析气井产能变化规律、制定相应的开发技术对策和排液工艺提供依据。

Abstract: Condensate gas reservoir is a kind of particular gas reservoir. During the primary depletion, it was inevitable that the retrograde condensation phenomena happened, thus enhancing the saturation of the liquid phase in the reservoir and reducing the productivity of the gas well. In this paper, on the basis of single well simulation of near wellbore retrograde condensation pollution and saturation distribution of the representative well (Bai 52 well) of Baimiao condensate gas field, assisting with the well test interpretation results and pseudosteady state equation, a quantitative method was put forward to evaluate the effect of near wellbore retrograde condensation pollution on gas well productivity. It provided the theoretical supports for the basis of analyzing condensate gas well productivity variation regularity, and the proper development strategy and drainage process.

Key words: condensate, saturation, retrograde condensation, skin factor, productivity
