摘　　要：为了提升裸眼分层测试求产、分层酸化、分层注/堵水等特殊作业的技术能力,需引入新工艺技术对裸眼井段进行跨式封隔。文章主要以涠洲某探井DST测试前裸眼封层作业为例,应用裸眼膨胀封隔器等工具进行分层隔离,满足了DST分层测试作业要求,扩展了裸眼井作业的技术手段,为今后类似裸眼失返漏失层跨式封隔提供了参考和借鉴。In order to enhance the technical capabilities of special operations such as open-hole layered testing for production,layered acidification,and layered injection/water plugging,it is necessary to introduce new process technologies for cross sealing of open-hole well sections.This article mainly takes the open-hole sealing operation before DST testing in a certain exploration well in Weizhou as an example,using tools such as open-hole expansion packers for layered isolation,meeting the requirements of DST layered testing operation,expanding the technical means of open-hole well operation,and providing reference and reference for cross type sealing of similar open-hole loss and leakage layers in the future.
