在停产的老井井眼中进行套管开窗侧钻,可恢复老井产能,取得显著的经济效益。介绍了KS101C井在常规套管开窗工艺基础上,针对可钻性极差的地层,通过侧钻工艺优选、工具改造,优化工艺措施和钻头类型,成功实施超深井套管开窗侧钻工艺的思路和方法。阐述了超深侧钻井眼轨迹控制、钻井液技术等方面的成功经验,对同类井的施工有一定借鉴意义。

Casing window sidetracking drilling can resume old well productivity,gain a remarkable economic benefit.It is base upon general casing cutting windows,aiming at bad feasibility stratum,through optimizing design sidetracking technology,changing tool,optimizing measure and choosing bit,we succeed in casing window sidetracking of ultradeep well KS101C.The well path control and drilling fluid technology good experience is introduced,It can use for reference to similar well.
