- 摘要:
- 为了有效解除某凝析气田近井地带反凝析、反向渗析污染问题，达到提高气井产能的目的，需要优化现有生产制度。对模拟吞吐作业下凝析气井的产能敏感因素、物性变化、近井地带压力变化进行研究，分析评价了减轻反凝析污染的可行性，为凝析气田的合理高效开发提供技术支持和决策依据。模拟结果表明注气吞吐是提高采收率的一种有效方式，对凝析气井的稳产和解决反凝析问题起到了较好的作用。所以应保持近井地带压力避免反凝析现象出现。
In order to enhance gas well productivity and solve the problem of retrograde condensate near the wellbore and reverse-dialysis pollution in Yingmaili， it is necessary to optimize and adjust the existing production system. For this purpose， studied are condensate gas well productivity sensitive factors， property change and change of pressure near the wellbore in throughput operation simulation and analyzed is the feasibility of mitigating the retrograde condensation pollution. The results show that gas injection is an effective way to improve oil recovery， and hold-up of pressure near the wellbore is very important for avoiding the retrograde condensation.
