Coal Bed Methane Drilling Rig (CBM Drill Rig)

Description

Coal bed methane drilling rig is especially used for exploring coal bed methane (CBM). CBM is an unconventional source of natural gas. CBM wells are very shallow (less than 1000 meters in depth). CBM drill rig is also used for water well drilling and mine rescue drilling. It is also suitable for mineral investigation. Those SPS2000, SPS2600, RPS3000, RPS3200 drill rigs are suitable for CBM explosion.

Features of CBM Drill Rig

1. Coal bed methane drilling rig is mounted on truck for easy transport. Working intensity is reduced in this way.
2. The whole drilling rig is driven by hydraulic system. This rig is equipped with all kinds of safety devices.
3. The drill head has two gear shifts, so different torques and rotating speeds can be realized. Coal bed methane drilling rig can meet the requirements of different hole sizes and drilling techniques. The maximum torque is 24750N.m for big-size hole and the maximum rotating speed is 300rpm for core drilling.
4. The main spindle can float 102 mm and the drill head be set to 80° angle in order to handle the drill rod easily.
5. Drilling pressure of the coal bed methane drilling rig can be adjusted precisely according to different geological conditions.
6. The braking system is set on the main shaft of the drill head in order to suit directional drilling and horizontal drilling.
7. The mast has a telescopic design which makes the drill tool handling very easy and provides a feeding stroke of 12.5m.
8. Air/water pipelines are used for connecting relevant accessories of different drilling techniques, such as fluid drilling, air drilling, foaming drilling, etc.

Advantage of CBM Drill Rig

Coal bed methane drilling rig can meet the requirements of mud drilling, air drilling, clean water drilling, foam drilling and the other types of drilling techniques.
