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.

方向工具

转向钻孔主要通过导向工具，滑动导向工具实现

滑动导向工具的特征在于，钻柱在引导操作期间不旋转，并且钻柱随钻头前进并沿井壁滑动。滑动导轨存在许多缺点：钻柱的扭矩和摩擦力大;井筒没有彻底清洁;钻的速度很慢等，但它仍占主导地位。

大多数定向钻井使用井下动力钻井工具。主要的滑动导向工具有：弧形套管电机，小型打地热井联系方式，可调弯曲接头，可变直径稳定器等。滑动导向工具组合：钻MWD/LWD动力钻头。

垢处理

根据业主提供的抽水井报告，当地地下水水质为碳酸钙和镁水，pH为7.1，为中性水。硬度为9.72毫克当量/升，极硬的水。 CL-SO42-为59.9 mg/l。它对钢管结构的腐蚀很弱，很容易引起系统结垢。

针对主机采取的保护措施

根据业主提供的抽水井报告，当地地下水水质为碳酸钙和镁水，pH为7.1，为中性水。硬度为9.72毫克当量/升，极硬的水。 CL-SO42-为59.9 mg/l。钢管结构腐蚀性很弱，因此水质极差。如果进入机器，系统很容易结垢，设备也会被腐蚀，从而导致热交换器性能下降或损坏，并且不能长时间使用。尽管化学方法可以减少这部分缺点。
