Compared with the DH150 well drilling rigns compared to the large rig：
Size and Flexibility: Small drilling machines are more portable and easier to transport due to their smaller size and lighter weight relative to larger drilling machines. They are also more flexible and can operate more easily in narrow or restricted work sites.
Cost and Efficiency: Small drilling machines are more affordable and more efficient than large drilling machines. They are usually simpler and easier to maintain and operate and typically require fewer workers.
Application Range: Small drilling machines are suitable for light-duty and medium-depth drilling tasks such as ground source heat pumps, water source heat pumps, groundwater monitoring, and water wells. While large drilling machines can handle deeper and larger diameter drilling work, they are relatively less flexible in adapting to the situations where small drilling machines are suitable.
Overall, small drilling machines have smaller size and flexibility, lower cost, and higher efficiency, making them an ideal choice for light-duty and medium-depth drilling operations.
