摘要:

对让纳若尔A层169井、大港千米桥板深7井、塔里木英买7井的凝析气样品在等容衰竭实验压降过程中的凝析气组分变化规律进行了分析,提出了一种直接相态恢复法。将该方法应用于让纳若尔凝析气藏相态恢复工作中,取得了很好的应用效果。对各级压力下相态恢复结果的对比表明,直接相态恢复法代表性好,可以作为一种有效的相态恢复方法得到应用,但是在应用过程中,原始地层压力不能下降较大,否则会影响恢复后流体的可靠性。

Abstract:

Acquiring the condensate gas phase behavior in original formations condition is difficult,but it is the most important in condensate gas reservoir development.The in-line phase recovery method was proposed after the changing law of condensate gas components in constant volume depletion experiment were analyzed by taking the condensate gas fluid samples from Well 169 in Zanarol Block,Well Banshen 7 in Dagang Qianmiqiao Block,and Well Yingmai 7 in Talimu Yingmai Block.The method was applied in Zanarol condensate gas reservoir,and has made the very good applicatiom effect. The applicatiom conditiom was studied by comparing the recovery results in different formation pressure.The results show that the in-line phase recovery method is representative and effective.But there exists an attentive problem in application, which is the formation pressure can't decrease too much,or the recovery result is unreliable.`

Key words: condensate gas reservoir, condensate gas constant component, constant volume depletion experiment, in-line phase recovery method, application effect
