草20-12-侧平13水平井是在定向井草20-12-斜13井中进行套管锻铣侧钻所完成的具有三维三段增斜剖面的水平井,井眼小,造斜率高,井身轨迹复杂。对钻井液的悬浮携带能力、润滑防卡性能及井眼稳定性都提出了更高的要求。
Grass 20-12-side flat 13 horizontal well is a horizontal well with three-dimensional three-section increasing inclined profile completed by casing forging and milling in directional well 20-12-inclined well 13 with small wellbore, high slope making rate, Well track complex. Suspended carrying capacity of drilling fluid, anti-jamming performance and wellbore stability are put forward higher requirements.
