摘要
利用托参1井原Φ244.5mm套管实施定向开窗侧钻水平井,在不大规模处理井内套管的条件下,成功地完成了在该井眼进行的分支定向施工,为今后的套管开窗技术及分支井技术打下了基础。本文分析了托参1井的基本情况、施工程序及事故预防技术等工艺,提出了套管开窗侧钻技术,可对老井段重新选层开发,有利于充分开发油气资源,节约甲方油气资源投资。
The directional sidetracking operation in Well Tuocanl has been carried out successfully through the existent casing without massive casing treatment, which laid foundation for the window cutting and sidetracking techniques in the future. In this paper, the essential features of Well Tuocanl, the operation plan of sidetracking and accident prevention measures are investigated. It is believed that the sidetracking technique can be used to develop newly selected intervals in an existent production well, which is favorable to the fully development of oil and gas resources and investment reduction.
