摘　　要：川东北地区河坝1井属一口高温、高压、高产气井,也是目前国内投入开发的井口压力最高的气井之一。针对河坝1井在投产中遇到的主要问题,分析了"三高"气井开采的关键技术,提出了采用可靠的井口装置和远程控制系统,合理选择高压平板闸阀,采用固定节流方式,合理分配节流压差,对油嘴进行硬化处理,采用法兰连接方式,以及直接开井等关键技术,确保了"三高"气井的安全平稳生产。With high temperature,pressure and gas yield,Heba 1 well in northeastern Sichuan Basin is one of wells with the highest wellhead pressure in China so far.According to the major problems occurring in production,the key exploitation technologies for three-high gas wells are obtained:(1) using reliable wellhead equipment and remote control system,(2) reasonably selecting high-pressure flat gate valve,(3) using fixed throttling method,(4)reasonably allocating throttle pressure difference,(5) hardening choke,(6) using flange connection,(7) opening well directly.These technologies may ensure a safe and stable exploitation for three-high gas wells.
