摘要
河南油田在张店地区首次部署了张 110 2井、张 13 0 1井 2口长裸眼、大斜度、多目标定向井 ,井深 2 4 3 0～2 5 0 0m ,最大井斜达 72° ,对钻井中靶精度要求高 ,钻井施工难度大。介绍了 2口井的地质设计、工程设计、井壁稳定、轨迹控制等内容。 2口井的井身剖面均设计为五段制 ,其中张 13 0 1井剖面为直增增增稳 ;张 110 2井剖面为直增稳增稳 ,钻具组合均采用双扶正器短钻铤钻具结构。采用聚合物低固相不分散强抑制钻井液体系 ,并实施屏蔽暂堵技术保护油气层 ,为今后开发类似油藏提供了成功的钻井经验。
Well Zhang-1102 and Zhang-1301 are two directional wells of long open hole, high inclination and multiple targets in Henan Oilfield, Zhangdian area. The total depths range from 2430m to 2500m, with the highest inclination up to 72°, and precise target hitting is required. The geology design, drilling engineering plan, well stabilization and trajectory control programs for the two wells are introduced.Five-section profile is adopted for both wells.Bottom Hole Assembly in the two wells combines the use of dual-stabilizer with short drill collar.As for drilling fluid system,low solid content and non-dispersion inhibitive polymer drilling fluid is used,and temporary shield plugging technology is carried out for formation protection.Drilling practice offers some successful experience for developing such similar reservoirs.
