ST 350 Large Pneumatic Crawler Drill Customized Water Well Borehole For Civil Business

ST 350 Crawler Mounted Drilling Rig Product Description

Reasonable overall layout uses the tractor-mounted or full ground chassis for transportation with good maneuverability.Very flexible in difficult roads and can be widely used in many fields such as resource exploration of hydrology wells, coalbed methane, the shallow layer of shale gas, terrestrial heat, etc, and can also be used for coal-mine gas exploitation salvage work. The top-mounted driving head principal shaft has a great drift diameter, suitable for many kinds of construction work such as slurry drilling, air drilling, and air foam drilling, meeting the demands for well-drilling at different terrain strata.

ST 350 Crawler Mounted Drilling Rig Parameters

ST 350 Crawler Mounted Drilling Rig Main Features

1. Lg140 speed regulation assembly and 10 speed ranges of automobile are adopted;
2. Large torque, strong bearing capacity, remote control and speed change can be realized
3. It has high installed power and 2-gear reverse speed, which is easy to deal with accidents;
4. With normally closed hydraulic chuck, easy to operate;
5. Independent operation of vertical shaft and winch can be realized;
6. The diameter of vertical shaft through hole is large, so it can be replaced by large hexagonal driving drill pipe.

Five experiences in finding water from large wells in Qingshi Mountain area:

1, The groundwater level of thick limestone is generally deep, and when the water level is shallow, fractured zones and fault zones can be found.

2, Thick marl is generally not easy to drill a well, and a well with good water volume can be found when the supply conditions are good due to severe weathering and fragmentation.

3, The dolomitic gray layer is better in areas with longer seasonal spring periods and is generally not easy to drill wells.

4, When the supply conditions of limestone mixed with shale are very certain, the conditions are better.

5, In general, in the case of engineering drilling rigs, the water level in the limestone formation is not high enough to reach the area, which means that there is generally not enough water pump to continuously pump water.
