摘要

在紧急情况下,需要把气井所采的凝析油回注到油层中去。针对这个问题,并结合平湖油田在实际操作中的具体情况,做了凝析油回注的模拟计算。在计算中,具体对注入压力、注入量、可回注的时间及注入凝析油的回采率、注入凝析油对岩石的润湿性等问题做了研究。研究结果在实际操作过程中被证实准确、可靠。

Abstract

In emergency, the condensate oil produced from gas well will be injected back to formation.For this question, condensate injection simulation was done and the result w as compared with practical operation data.Injection pressure, injection rate, injection time and condensate recovery were optimized.In addition, the effect of condensate injection on rock wettabiltiy was discussed.Field practice proved that computation results were accurate and reliable.
