TH12301CH井是一口短半径侧钻水平井,位于塔河12区,为了建立原井TK1223开发产能,开发奥套系油藏,利用侧钻水平井技术改善开发效果,提高产能及采收率而开发一口侧钻水平井;本井完钻井深6606.83m,垂深6391.67m创中石化水平井垂深最深记录。本井井眼轨迹设计合理,井眼轨迹控制方法正确,使用先进的耐高温MWD、耐高温动力钻具,技术保障措施得当,各方配合密切,优质快速完成本并的施工。本文介绍井的轨迹控制方面的特点、难点和对策,轨迹控制过程,并给出几点建议。
The TH12301CH well is a short-radius sidetracking horizontal well located in Tahe 12 Zone. In order to establish the production capacity of the original well TK1223, the development of the Oroxenian reservoir and the development of a horizontal well with lateral drilling to improve the development effect and increase productivity and oil recovery Sidetracking horizontal wells; completion of this well drilling depth 6606.83m, vertical depth 6391.67m Chuangping Petrochemical horizontal well deepest record. Wellbore trajectory design is reasonable, well trajectory control method is correct, the use of advanced high temperature MWD, high temperature-resistant power tools, technical support measures properly, all parties with close, high quality and rapid completion of the construction. This article introduces the features, difficulties and countermeasures of well trajectory control, trajectory control process, and gives some suggestions.
