摘要
以英买7带底油的凝析气藏为研究对象,开展了利用水平井提高英买7凝析气藏底油采收率的可行性研究和实践。在建立气藏地质模型的基础上,运用ECLPSE300组分数值模型软件,对水平井水平段的纵向位置、水平段长度和采油速度进行了开发可行性的模拟研究,得出了在不影响天然气采收率的前提下,要提高底油的采收率应将水平井水平段部署在油气界面之上1～2m处,水平段长度为300m,采油速度控制在2.5%以下较为合理的认识。通过该气藏YM7-H1水平井底油开采实践,上述认识得到了证实并取得了提高底油采收率的实效。
This paper investigated feasibility analysis and practical application of horizontal well in Yingmai-7 gas condensate reservoir with bottom water to enhance its recovery efficiency.On the basis of the geologic model,ECLIPSE 300 was used to simulate the depth and length of the horizontal section,and reasonable recovery rate.It was concluded that the horizontal section,whose favorite length is about 300 m,should locate 1-2 m above the GOC,and the reasonable recovery rate should be kept below 2.5%.These research results have been proved by practical application of the horizontal well YM7-H1.
