苏北工区二氧化碳注气井取换套施工技术应用

Construction Technology Application of Carbon Dioxide Gas Injection Wel Replacement in North Jiangsu Works Area

为提高注二氧化碳井的利用率,2018年油服中心开始对该类井进行换取套管施工及研究,通过一年多的实践,目前已逐步形成了对苏北工区二氧化碳注采区比较适合的取换套工艺技术,通过对已经成功取换套的井经验,为以后相似井况的井取换套提供技术借鉴。

In order to improve the utilization of carbon dioxide injection wells,In 2018,the oil suit center began to exchange casing construction and research for such wells.Through more than one year’s practice,a suitable technology for the carbon dioxide injection and production area in North Jiangsu has been gradually formed.Through the successful experience of casing replacement,this paper provides a technical reference for similar wells in the future.
