摘要
利用老井眼定向侧钻新井眼，对地质构造重新认识和评价，可大大降低钻井成本，加快勘探开发的进度。本文介绍了曲斜七井悬空侧钻采用的钻具组合及工艺措施，并对其泥浆技术和降压解卡技术也进行了描述。该井的成功，不但取得了良好的经济效益，也为日后充分利用老井眼侧钻新井眼积累了经验。
Taking use of old well for
orientational sidetracking to reconsent and reevaluate geological configuration can greatly
reduce drilling cost and accelerate exploration and development process. This paper introduced
drill assembly and technological process while suspended sidetracking in Quxie 7 well.Its'
drilling fluid technology and decompressional releasing stuck technique are also described.
Success in this well can not only get remarkable economic benefit but also accumulate
experience for futural old well sidetracking technique.
