钻井实用技术必备
旋转制导系统（RSS）
旋转引导工具沿着期望的轨迹直接引导钻头，从而防止钻柱在井壁上滑动，允许井眼被很好地清洁，同时允许根据地层选择合适的钻头。这可以显着减少或消除滑动导向工具的缺陷。
目前，旋转式转向工具主要包括：VDS自动垂直直井钻井系统，SDD自动垂直钻井系统，ADD自动定向钻井系统，RSD旋转导向钻井系统，RCLS旋转闭环钻井系统等。
钻井工程术语
开发井:是指在油气田开发中钻探的各种石油生产井。注水注气井或调整井，在已开发的油气田钻探补充井，保持一定的产量，研究开发过程中地下条件的变化。扩建井，检查数据井等
垂直井:井眼轴通常沿垂直方向及其井角。底孔的水平位移和全角的变化率都在有限的范围内。
定向井:沿预先设计的井眼轨道，在给定方向上与井口垂直于井口一定距离，到达目标井。
Cluster Wells:在井场或钻井平台上计划钻两个或多个定向井（可能包括垂直井）。
打井施工工艺及注意要点
Well drilling c***truction technology and attention points
1. According to the requirements of the water output of the well, the wellbore structure is designed with the well depth and the caliper, and the drilling machine type and the corresponding auxiliary equipment are selected in combination with the stratum.
2. Before drilling, the machine should be leveled, the equipment should be arranged, the equipment should be stored, the tower should be erected, and the rig should be placed.
3. Drilling holes in the bedrock aquifer, *** is better to use rotary core drilling. During the drilling process, hydrogeological observati*** such as groundwater level and the disappearance of circulating liquid holes should be carried out.
4. During the process of drilling into holes, it should be described according to technical requirements, layered soil samples, water samples, temperature measurement, etc. Also ensure the quality and quantity of the sample.
