摘　　要：在对热采低效井数据统计的基础上,对油井低效原因进行系统分析,配套系列技术,做到套管损坏井治理与防治相结合。通过研究,形成了地面—井筒—油藏一体化的多元复合化学泡沫调剖技术和HDCS、压裂防砂地层改造强化采油配套工艺,针对性解决了高含水井、低产井热采开发效果差的问题。现场应用表明,该系列技术的应用有效提高了水平井的开发效果,取得了良好的经济效益。The reasons for inefficient oil wells have been systematically analyzed based on data statistics of thermal recovery wells,and supporting techniques have been completed to treat casing failure well in conjunction with prevention. Researches have developed supporting techniques for enhanced oil recovery including integrated surface—wellbore—reservoir compound chemical foam profile control,HDCS,and fracturing sand control,thus solved the problem of low thermal recovery efficiency in high water cut wells and stripped wells. Field applications indicate that these techniques have effectively increased the development effect of horizontal wells and achieved satisfactory economic benefit.
