欢 2 14 30 16C井位于辽河欢喜岭油田欢 14 16块 ,是为恢复欢 2 1430 16井产能而施工的一口139 7mm套管开窗侧钻小眼井定向井。该井在 196 5m处开窗 ,完钻井深 2 36 6m ,裸眼长度 4 0 1m ,井底水平位移 2 6 5 4 0m ,靶点位移 2 0 3 5 5m ,靶心距 3 17m ,最大井斜角 2 8° ,固井质量优。该项技术做为恢复老井产能的一项措施 ,值得推广和应用 Huan 2 14 30 16C Well located in the Huanxiling Huan oil field in Liaohe Huan 14 16 block, is to restore Huan 2 1430 16 production capacity of the construction of a  139 7mm casing window drilling small-hole directional well. The well was drilled at a depth of 196 m with a depth of 2 366 m and an unobtrusive length of 4 0 1 m. The horizontal displacement at the bottom of the well was 264500m, the target displacement was 20355m, the target center distance was 317m, the maximum inclination angle 2 8 °, good cementing quality. The technology as a measure to restore the productivity of old wells, it is worth promoting and application
