摘　　要：井底积液是凝析气井生产中的一个重大问题。陆上油田在气井停喷后通常采用人工法排出井底积液。对于海上气井来说,由于受成本及平台的局限,在投产之前进行排液采气配套工艺前期论证意义重大。介绍了各种排液采气工艺的优缺点。提出海上凝析气井排液采气配套工艺前期论证的方法并对某气田上的气井进行了排液采气论证研究,提出采用变频装置以适应油藏、油井情况不断变化这一特点,并建议采用水下井口,以避免井底积液以及采取相应工艺措施所带来的巨大成本。The hole liquid loading is still a great issue in gas condensate well production. For the Onshore oil field, several artificial processes were used to discharge bottom hole liquid after gas well stopping spraying. When it comes to offshore gas well, with a limited platform and cost restriction, to argue the drainage gas recovery matching technology before going into production is very important. The advantages and disadvantages of different drainage gas recovery technologies were introduced in this paper. The previous argu- ment method of drainage gas recovery matching technology for offshore gas condensate well was proposed and then a case study was conducted. Converter plant was adopted to subject to the characteristics of reservoir and oil well changing. In order to avoid the huge costs resulted from the bottom liquid and corresponding technical measures, it is suggested that well head under water could be perfect.
