摘要
陕北两水平对接采卤井,对接靶点垂深2541.42m,水平距离365.89m,设计造斜点垂深2328m,造斜率25~30°/100m。垂直井深达2311.5m时,井斜1.08°,偏距5.69m,远离靶区,据此根据造斜钻具性能,造斜点改为2311.5m。
Two horizontally butt-jointing bittern wells drilled in northern Shaanxi, their target butt-jointing vertical depth is 2541.42m, horizontal distance 365.89m, designed kick-off point vertical depth 2328m, kick-off ratio 25-30o/100m. When the vertical well depth is 2311.5m, well deviation 1.08o, the offset shall be 5.69m, thus far away from the target area. Thereof, depend on kick-off drilling tool performance, the KOP is then redesigned to 2311.5m.
